[embodiment]
As shown in Figure 1, a kind of screen display content method for updating may further comprise the steps:
Step S10 obtains the displaying contents after upgrading preceding displaying contents and upgrading when detecting the incident of upgrading screen display content.The incident of upgrading screen display content can be that the user moves the page by button, touch screen or roll mouse roller and produces, as user's browsing page or when opening explorer, by direction button or roll mouse roller, make whole screen display content move up or down delegation or multirow or switching full page; The incident of upgrading screen display content can also be the variation of selected object, selected object is meant the content that highlights in the screen content, the picture of choosing as the netpage user that highlights or literal etc., selected file that highlights etc. in the explorer and for example, the user can be switched selected object by button or touch screen, thereby produces the incident of upgrading screen display content.
Step S20, the displaying contents after judge upgrading with upgrade preceding displaying contents whether identical part arranged, if, execution in step S30, if not, execution in step S40.Wherein, when the user is switched selected object by button or touch-screen, except selected object changes, the displaying contents after the renewal with upgrade preceding displaying contents in other guide identical.When making whole screen display content move up or down delegation or multirow, also may there be identical part in user's direction of passage key or roll mouse roller.In addition, the user switches full page by button or roll mouse roller, does not then have identical part.
The displaying contents of the displaying contents before the displaying contents of the displaying contents before the step S30, copy update, drafting change, the renewal that will duplicate and the change of drafting merges and shows.In the above-mentioned situation, the content of screen display after renewal with upgrade before when identical part is arranged, then duplicate before the renewal of identical part displaying contents to buffer zone as a setting layer, the displaying contents of drawing change then is in buffer zone, and the displaying contents with the change of the displaying contents before the renewal of duplicating in the buffer zone and drafting merges and demonstration again.During as user's browsing page, by button or touch-screen switching selected object is changed, when producing the incident of upgrading screen display content, displaying contents before the copy update is layer as a setting, draws selected object (being depicted as not selected state) before upgrading and the selected object (being depicted as selected state) after the renewal cover original opposite position to buffer zone content again.
Step S40 draws displaying contents and demonstration after upgrading.During user's browsing page, make the full page switching by button or roll mouse roller, wanting content displayed after the renewal and upgrading preceding content displayed does not have identical part, then directly draws the displaying contents interior and demonstration to buffer zone after upgrading.
The method of above-mentioned screen display content update, adopt earlier the preceding displaying contents of displaying contents after upgrading and renewal to be compared and judge whether identical part, if have, then duplicate identical part, again the content of change is drawn, need not same section is drawn, improved the drafting efficient that screen display content upgrades greatly.The method of above-mentioned screen display content update can obviously be improved the screen display content updating efficiency for the portable mobile termianl that this processing power of mobile phone is short of relatively, avoids occurring the situation that screen is torn.Particularly when display text,, can reduce calculated amount more because the demonstration of literal needs the process of a complexity from the character code to the displaying contents.Therefore, the method for above-mentioned screen display content update is particularly suitable as the method for mobile phone literal update displayed.
For the idiographic flow that upgrades screen display content better is described, lifts several specific embodiments below and describe in detail, but be not limited thereto.As shown in Figure 2, in one embodiment, when user's browsing page or explorer, switches by button or touch-screen selected object is changed, but when screen display content did not change except that selected object, concrete step of updating was as follows:
Step S210, obtain the displaying contents before upgrading when detecting the incident of the renewal screen display content that selected object changes and upgrade after displaying contents.By detecting, whole screen display content does not move up and down, and only switches by button or touch-screen for the user to make selected object that variation take place.During as browsing page, the selected object before upgrading is literal " physical culture ", and the selected object after the renewal is literal " amusement ".
Step S220, the displaying contents after judge upgrading with upgrade preceding displaying contents whether identical part arranged, if, execution in step S230.In the present embodiment, detect the user and switch in current page by button or touch-screen and move, selected object is changed, then change except selected object, other do not change, the displaying contents after promptly upgrading with upgrade preceding displaying contents identical part arranged.
Displaying contents before the step S230, copy update, and the selected object after repainting the preceding selected object of renewal and upgrading are with the also demonstration of selected object merging after selected object before the renewal of displaying contents before the renewal of duplicating and drafting and the renewal.Present embodiment only changes for selected object, the displaying contents after the renewal with upgrade before displaying contents have identical.Therefore original coordinate transformation is become the coordinate of buffer zone, and the displaying contents before the copy update is in buffer zone, background as the bottom, repaint the selected object before the renewal that gets access to again and upgrade after selected object, respectively according to its corresponding coordinate, override the original image that is positioned in the buffer zone on this corresponding coordinate, and the displaying contents before the renewal that will duplicate is shown on the screen with the content output that preceding selected object of the renewal that repaints and renewal back selected object are merged into buffer zone.Wherein, every row of screen display content and object all have its corresponding coordinate.With the document is example, and each object in the document all has coordinate, and this coordinate is to calculate with respect to the initial position of entire document.The size of buffer zone is big or small the same with on-screen display (osd) area.Before selected object before upgrading is meant update event takes place, the selected object that highlights in the screen, the selected object after the renewal is meant and takes place to be chosen the object that highlights by the user after the update event.As the selected literal that highlights before upgrading in the webpage is " physical culture ", upgrading the selected literal that highlights in back is " amusement ", after the displaying contents that renewal is preceding copies to buffer zone, repaint " physical culture " and " amusement ", then it is copied in the buffer zone on the corresponding coordinate, " physical culture " does not highlight, and " amusement " becomes and highlight.
As shown in Figure 3, in one embodiment, when user's browsing page or explorer etc., direction of passage key or roll mouse roller make whole screen move up delegation or multirow, or move down delegation or multirow, produce the incident of upgrading screen display content.Concrete step of updating is as follows:
Step S310, detect obtain the displaying contents before upgrading when screen display content moves up or down the incident of renewal screen display content of delegation or multirow and upgrade after displaying contents.When detecting user's browsing page or explorer etc., direction of passage key or roll mouse roller make whole screen move up delegation or multirow, or move down delegation or multirow, produce the incident of upgrading screen display content.
Step S320, the displaying contents after judge upgrading with upgrade preceding displaying contents whether identical part arranged, if, execution in step S330 then.In the present embodiment, detect the user by mobile button or roll mouse roller, make whole screen display content move up or down delegation or multirow, but full page do not take place to switch fully, the displaying contents after then upgrading with upgrade preceding displaying contents identical part arranged.In addition, in the present embodiment, by obtaining the coordinate offset amount that screen display content moves, analyze after upgrading displaying contents with upgrade preceding displaying contents whether identical part arranged.With the webpage is example, and this coordinate can calculate with the first row contains starting point coordinate of web page display contents.Screen display content moves the displaying contents that is meant whole screen and is moved, and promptly whole screen moves up or down delegation or multirow.The coordinate offset amount is meant when screen display content moves, the variable quantity that its coordinate takes place.In addition, whole screen display size is limited, and the line number that can show is limited, and the interval size of then corresponding coordinate is the same with line number, and then can set a predetermined value is maximum display line numerical value.When user's direction of passage key or roll mouse roller make whole screen move up or down delegation or multirow, do not carry out the switching fully of full page, the coordinate offset amount that the screen display content that then obtains moves should be non-vanishing, and coordinate offset amount absolute value is less than this predetermined value.With the webpage is example, as the screen display content coordinate range before upgrading is 1-10, screen display content coordinate range after the renewal is 3-12, this predetermined value is 10, coordinate offset amount absolute value is 2 less than this predetermined value, and then screen display content is moved, and the page that do not switch, therefore, the displaying contents after the renewal with upgrade before displaying contents exist part identical.If the coordinate offset amount is 10, then switching has taken place in full page, will not have identical part.
Step S330, obtain the coordinate offset amount that screen display content moves, according to the displaying contents before this coordinate offset amount copy update, draw newly-increased content, the displaying contents before the renewal that will duplicate according to the coordinate offset amount with draw newly-increased content and merge and show.In the present embodiment, behind buffer zone, have a part of clear area at buffer zone according to the displaying contents before the coordinate offset amount copy update, promptly wait to draw the district, the drafting for the treatment of that then newly-increased displaying contents is plotted to buffer zone is distinguished.As show before upgrading in the webpage for coordinate be 1 to 10 content, to show after the renewal for coordinate be 3 to 12 content, the coordinate offset amount is 2, duplicate 3 to 10 content to buffer zone according to this coordinate offset amount, the white space that in buffer zone, can have two row, with newly-increased coordinate is that 11 and 12 content is plotted to two line space white regions in the buffer zone, and the coordinate that with the coordinate that duplicates is 3 to 10 content and drafting then is that 11 and 12 content merges the back and shows.
Shown in Figure 4, in one embodiment, when user's browsing page or explorer, by button or touch-screen switching selected object is changed, and impel whole screen display content to move up or down delegation or multirow, but whole screen display content does not take place to switch fully, the displaying contents after then upgrading with upgrade preceding displaying contents identical part arranged, concrete step of updating is as follows:
Step S410 detects that selected object changes and screen display content when moving up or down the incident of renewal screen display content of delegation or multirow, obtain the displaying contents before upgrading and upgrade after displaying contents.Detect the user and switch selected object by button or touch-screen, selected object changes and makes whole screen display content also move up or down delegation or multirow, produces the incident of upgrading screen display content.
Step S420, the displaying contents after judge upgrading with upgrade preceding displaying contents whether identical part arranged, if, execution in step S430 then.Detect selected object and whole screen display content moves up or down delegation or multirow, but whole screen display content do not take place to switch completely, the displaying contents after therefore upgrading with upgrade preceding displaying contents identical part arranged.
Step S430, obtain the coordinate offset amount that screen display moves, according to the displaying contents before this coordinate offset amount copy update, draw preceding selected object of newly-increased displaying contents and renewal and the selected object after the renewal, and, draw the displaying contents and preceding selected object and the selected object after the renewal of renewal that increase newly and merge and demonstration the displaying contents before the copy update.Displaying contents after the renewal with upgrade before displaying contents identical part is arranged, then get access to the coordinate offset amount that whole screen display content moves earlier, according to the displaying contents before the coordinate offset amount copy update, draw newly-increased displaying contents again, repaint the selected object before upgrading then and upgrade after selected object, the three is merged the back shows.With the page refreshment is example, according to the displaying contents before the coordinate offset amount copy update behind buffer zone, there is a part of clear area at buffer zone, promptly wait to draw the district, then newly-increased displaying contents is plotted to buffer zone wait draw the district, repaint the selected object before upgrading again and upgrade after selected object cover on the corresponding coordinate position.As show before upgrading in the webpage for coordinate be 1 to 10 content, the selected object that highlights before upgrading is " physical culture ", to show after the renewal for coordinate be 3 to 12 content, the selected object that highlights after the renewal is " amusement ", then the coordinate offset amount is 2, duplicate 3 to 10 content to buffer zone according to this coordinate offset amount, the white space that in buffer zone, can have two row, with newly-increased coordinate is that 11 and 12 content is plotted to two line space white regions in the buffer zone, the selected object " physical culture " that repaints then before upgrading does not highlight content, selected object " amusement " after drafting is upgraded will be shown on the screen after three's merging for highlighting content.
As shown in Figure 5, in one embodiment, user's browsing page or explorer, by button or roll mouse roller full page is switched, produce the incident of upgrading screen display content, whole screen display content takes place to switch completely, then with upgrade before displaying contents do not have overlapping part.Concrete step of updating is as follows:
Step S510, when detecting whole screen display content the incident of the renewal screen display content that switches completely taking place, obtain the displaying contents before upgrading and upgrade after displaying contents.When detecting user's browsing page or explorer, make full page take place to switch completely, produced the incident of upgrading screen display content by button or roll mouse roller.
Step 520, the displaying contents after judge upgrading with upgrade preceding displaying contents whether identical part arranged, if not, execution in step S540.The user switches whole screen display content by button or roll mouse roller, the displaying contents after then upgrading with upgrade preceding displaying contents and do not have identical part.In the present embodiment, can be by getting access to the coordinate offset amount that screen display content moves, whether the displaying contents of analyzing after upgrading preceding displaying contents and upgrading has identical part.Specifically: whole screen display size is limited, and the line number that can show is limited, and the interval size of then corresponding coordinate is the same with line number, and then can set predetermined value is maximum display line numerical value.The coordinate offset amount that moves when screen display content is more than or equal to predetermined value, and this screen display content full page switches, the displaying contents after the renewal with upgrade before displaying contents do not have identical part.
Step S540 draws displaying contents and demonstration after upgrading.The coordinate offset amount that screen display content moves has surpassed predetermined value, and then variation has taken place the content of whole screen fully, and the displaying contents before displaying contents after the renewal and the renewal does not have overlapping part, does not promptly have identical part.The user moves and makes full page that switching completely take place, and then directly draws the displaying contents interior and demonstration to buffer zone after upgrading.
As shown in Figure 6, the system that a kind of screen display content upgrades comprises and detects acquisition module 10, processing module 20, update module 30 and output module 40.Wherein,
When detecting acquisition module 10 and being used to detect the incident of upgrading screen display content, obtain the displaying contents before upgrading and upgrade after displaying contents.Detect acquisition module 10 be used to detect the user by button or, touch screen or roll mouse roller move the incident of the renewal screen display content that the page produces, as user's browsing page or when opening explorer, detect acquisition module 10 and detect the user by direction button or roll mouse roller, make whole screen display content move up or down delegation or multirow, or switch full page; The incident that detects acquisition module 10 detected renewal screen display contents can also be the variation of selected object, selected object is meant the content that highlights in the screen content, the picture of choosing as the netpage user that highlights or literal etc., selected file that highlights etc. in the explorer and for example, the user can be switched selected object by button or touch screen, thereby produces the incident of upgrading screen display content.
In the present embodiment, the content of screen display after renewal with upgrade before when identical part is arranged, then update module 30 is duplicated displaying contents before the renewal of identical part to buffer zone layer as a setting, draws the displaying contents that increases newly then in buffer zone.During as user's browsing page, detect acquisition module 10 and get access to the user is switched the renewal screen display content that makes the selected object variation by button or touch-screen incident, judge module 20 is judged except selected object changes, other parts are identical, identical part is promptly arranged, displaying contents before update module 30 copy updates, selected object (being depicted as not selected state) before drafting is upgraded again and the selected object (being depicted as selected state) after the renewal are to the content of the original opposite position of buffer zone covering.Wherein, buffer zone shows that size is the same with the screen display size, and promptly buffer zone is equivalent to one and the equirotal picture of screen display.
The system of above-mentioned screen display content update, adopt judge module 20 earlier the preceding demonstration of displaying contents after upgrading and renewal to be compared and judge whether identical part, if have, then update module 30 is duplicated identical part, again the content of change is drawn, need not same section is drawn, improved the drafting efficient that screen display content upgrades greatly.
In addition, detecting acquisition module 10, to detect the incident of upgrading screen display content be in following four kinds of situations any one: selected object changes and screen does not move; Screen display content moves up or down delegation or multirow and selected object when constant; Selected object changes and screen display content moves up or down delegation or multirow; Whole screen display content takes place to switch completely.When the system that screen display content upgrades detected wherein any one situation, the process of renewal was inequality, was described in detail below the detailed process that different situations are upgraded.
(1) incident of renewal screen display content is that selected object changes and screen does not move.
Detecting acquisition module 10, to detect the incident of upgrading screen display content be that selected object changes and screen when not mobile, obtain the displaying contents before upgrading and upgrade after displaying contents.Detect acquisition module 10 by detecting, whole screen display content does not move up and down, and only switches by button or touch-screen for the user to make selected object that variation take place.During as browsing page, the selected object before upgrading is literal " physical culture ", and the selected object after the renewal is literal " amusement ".
Displaying contents before update module 30 copy updates, and repaint the selected object before upgrading and upgrade after selected object, with the selected object before the renewal of the displaying contents before the renewal of duplicating and drafting with the selected object after upgrading merges and by output module 40 output demonstrations.Present embodiment only changes for selected object, the displaying contents after the renewal with upgrade before displaying contents have identical.Therefore update module 30 becomes original coordinate transformation on the coordinate of buffer zone, and the displaying contents before the copy update is in buffer zone, background as the bottom, repaint the selected object before the renewal that gets access to again and upgrade after selected object, respectively according to its corresponding coordinate, override the original image that is positioned in the buffer zone on this corresponding coordinate, and the displaying contents before the renewal that will duplicate is shown on the screen with the content output that preceding selected object of the renewal that repaints and renewal back selected object are merged into buffer zone.Wherein, every row of screen display content and object all have its corresponding coordinate.With the document is example, and each object in the document all has coordinate, and this coordinate is to calculate with respect to the initial position of entire document.The size of buffer zone is big or small the same with on-screen display (osd) area.Before selected object before upgrading is meant update event takes place, the selected object that highlights in the screen, the selected object after the renewal is meant and takes place to be chosen the object that highlights by the user after the update event.As the selected literal that highlights before upgrading in the webpage is " physical culture ", upgrading the selected literal that highlights in back is " amusement ", after the displaying contents that renewal is preceding copies to buffer zone, update module 30 repaints " physical culture " and " amusement ", then it is copied in the buffer zone on the corresponding coordinate, " physical culture " does not highlight, and " amusement " becomes and highlight.
(2) to be that screen display content moves up or down delegation or multirow and selected object constant for the incident of upgrading screen display content.
Detect acquisition module 10 and detect the incident of upgrading screen display content to be that screen display content moves up or down delegation or multirow and selected object constant, obtain the displaying contents before upgrading and upgrade after displaying contents.When detecting acquisition module 10 and detecting user's browsing page or explorer etc., direction of passage key or roll mouse roller make whole screen move up delegation or multirow, or move down delegation or multirow, produce the incident of upgrading screen display content.
Judge module 20 judge after upgrading displaying contents with upgrade preceding displaying contents identical part arranged.In the present embodiment, detect the user by mobile button or roll mouse roller, make whole screen display content move up or down delegation or multirow, but full page do not take place to switch fully, the displaying contents after then upgrading with upgrade preceding displaying contents identical part arranged.In addition, in the present embodiment, obtain the coordinate offset amount that screen display content moves by detecting acquisition module 10, analyze after upgrading displaying contents with upgrade preceding displaying contents whether identical part arranged.With the webpage is example, and this coordinate can calculate with the first row contains starting point coordinate of web page display contents.Screen display content moves the displaying contents that is meant whole screen and is moved, and promptly whole screen moves up or down delegation or multirow.The coordinate offset amount is meant when screen display content moves, the variable quantity that its coordinate takes place.In addition, whole screen display size is limited, and the line number that can show is limited, and the interval size of then corresponding coordinate is the same with line number, and then can set a predetermined value is maximum display line numerical value.When user's direction of passage key or roll mouse roller make whole screen move up or down delegation or multirow, do not carry out the switching fully of full page, then detecting the coordinate offset amount that screen display content that acquisition module 10 obtains moves should be non-vanishing, and judge module 20 is judged these coordinate offset amount absolute values less than this predetermined value, the displaying contents after then upgrading with upgrade preceding displaying contents and have identical part.With the webpage is example, as the screen display content coordinate range before upgrading is 1-10, screen display content coordinate range after the renewal is 3-12, this predetermined value is 10, coordinate offset amount absolute value is 2 less than this predetermined value, then screen display content is moved, and the page that do not switch, judge module 20 judge after the renewal displaying contents with upgrade before displaying contents exist part identical.If the coordinate offset amount is 10, then switching has taken place in full page, then judge module 20 judge after the renewal displaying contents with upgrade preceding displaying contents and do not have identical part.
Detect acquisition module 10 and obtain the coordinate offset amount that screen display content moves.The displaying contents of update module 30 before, draw newly-increased content according to this coordinate offset amount copy update, the displaying contents before the renewal that will duplicate according to the coordinate offset amount with draw that newly-increased content merges and show by output module 40 outputs.In the present embodiment, there is a part of clear area in the displaying contents of update module 30 before according to coordinate offset amount copy update at buffer zone behind buffer zone, promptly waits to draw the district, draws newly-increased displaying contents waiting to draw and distinguish to buffer zone then.As show before upgrading in the webpage for coordinate be 1 to 10 content, to show after the renewal for coordinate be 3 to 12 content, the coordinate offset amount is 2, update module 30 is duplicated 3 to 10 content to buffer zone according to this coordinate offset amount, the white space that in buffer zone, can have two row, be that 11 and 12 content is plotted to two line space white regions in the buffer zone again with newly-increased coordinate, the coordinate that with the coordinate that duplicates is 3 to 10 content and drafting then is that 11 and 12 content merges and shows by output module 40 outputs.
(3) incident of renewal screen display content is that selected object changes and screen display content moves up or down delegation or multirow.
