Display line on screen, user can be configured according to the size of display screen.Initial anchor point row can be with the anchor arranging
Point display line is identical, it is also possible to different.For example, the data item line number that screen can show is 3 row, arranges anchor point epideictic behaviour
2nd row, then, when focus carries out rolling and updates, the 2nd row that the position of focus is positioned on screen, initial anchor point row can set
Being set to the 2nd row, with the change of current direction key value, the position of anchor point row changes with the renewal of focal position.
In the present embodiment, data source is made up of the dynamically incoming data item of user, and this data source is according to user setup
Queueing discipline is arranged, and the data item number that this queueing discipline can be shown according to screen by user and roll mode determine,
Roll mode includes：Fixing row roll row, fixing row rolling column and roll row and column simultaneously.For example, the row that screen can show
Number is 3 row, and columns is 5 row, when the number of data item in data source is 100, then can arrange data source arrangement mode is 5
Row, now data source is arranged in 20 row, 5 row, and when according to current key assignments direction for moving up or moving down, screen can
To realize the scrolling display to data item all in data source, each time can be with 3 row data item in display data sources.For example, if
Put the 2nd row on anchor point epideictic behaviour screen, now anchor point behavior the 2nd row, when current key assignments direction is for moving down, determine target
Data behavioral data item the 3rd row, now target data rows is not equal to anchor point row, therefore, determines whether total line number of data source
20 deduct target data rows 3 deducts anchor point display line 2 more than screen display line number 3, determine the corresponding data source of data item to
Lower section last column upwards is not explicitly shown on screen.
Again for example, arranging the 2nd row on anchor point epideictic behaviour screen, now anchor point behavior the 19th row, current key assignments direction is
When moving down, determining target data behavior data item the 20th row, now target data rows is not equal to anchor point row, therefore, enters one
Step judges that total line number 20 of data source deducts target data rows 20 and deducts anchor point display line 2 less than screen display line number 3, determines number
It is not explicitly shown on screen according to the corresponding data source of item last column in a downward direction.
During it should be noted that current key assignments direction is for moving up, it is judged that whether target data rows shows more than anchor point
OK, if it is, determine that the corresponding data source of data item last column in an upward direction is not explicitly shown on screen, no
Then, determine that the corresponding data source of data item last column in an upward direction is shown on screen.
For example, arranging the 2nd row on anchor point epideictic behaviour screen, now anchor point behavior the 2nd row, current key assignments direction is for upwards
When mobile, determining target data behavior data item the 1st row, now target data rows is less than anchor point display line, determines data item pair
The data source answered last column in an upward direction is shown on screen.
In one embodiment of the invention, in order to determine the corresponding data source of data item in the direction of current direction key value
On last row whether be shown on screen, also included before step 104：Pre-set the anchor point that anchor point is listed on screen
Display row；Step 104 also includes：When current direction key value is for moving right, it is judged that total columns of data source deducts number of targets
Whether deduct anchor point display row not less than screen display columns according to row, if it is, determine the corresponding data source of data item to
Last row in right direction are not explicitly shown on screen, otherwise, it determines the corresponding data source of data item is in right direction
Last row are shown on screen.
Wherein, anchor point display row are similar with anchor point display line, and the anchor point display row that anchor point is listed on screen are focus and enter
Row rolls when updating, and the display row that corresponding focus is fixed on screen, user can set according to the size of display screen
Put.For example, the data item columns that can show when screen is 6 row, can arrange anchor point and show that being classified as the 3rd arranges, i.e. when focus is entered
Row rolls when updating, and focus is fixing to be shown on screen the 3rd row.
For example, in data source, the number of data item is 100, and the line number that screen can show is 4 row, and columns is 5 row, now
Roll mode is fixing row rolling column, then the arrangement mode that can arrange data source is 4 row, i.e. data source be arranged in 4 row, 25
Row.Arranging anchor point to show and be classified as on screen the 3rd row, now anchor point is classified as the 3rd row, when current key assignments direction is for moving right, really
The data that set the goal are classified as data item the 4th row, and now target data row are not equal to anchor point row, therefore, determine whether data source
Total columns 25 deducts target data row 4 and deducts anchor point display row 3 more than screen display columns 5, determines the corresponding data of data item
Source last row in right direction are not explicitly shown on screen.
Again for example, arranging anchor point to show and be classified as on screen the 3rd row, now anchor point behavior the 23rd arranges, and current key assignments direction is
When moving right, determining that target data is classified as data item the 24th row, now target data row are not equal to anchor point row, therefore, enter one
Step judges that total columns 25 of data source deducts target data row 24 and deducts anchor point display row 3 less than screen display columns 5, determines number
It is shown on screen according to the corresponding data source of item last row in right direction.
During it should be noted that current key assignments direction is for being moved to the left, it is judged that whether target data row show more than anchor point
Row, if it is, determine that the corresponding data source of data item last row in left direction are not explicitly shown on screen, no
Then, determine that the corresponding data source of data item last row in left direction are shown on screen.
For example, arranging anchor point to show and be classified as on screen the 3rd row, now anchor point is classified as the 3rd row, and current key assignments direction is for the left
When mobile, determining that target data is classified as data item the 2nd row, now target data row are less than anchor point display row, determine data item pair
The data source answered last row in left direction are shown on screen.
In one embodiment of the invention, in order to determine the target data rows at first object data item place, in step
Before 103, also include：In advance corresponding numbering, wherein, A are set for each data item in data sourcei,j=(i-1) n+j-1,
