Detailed Description

The technical scheme provided by the present invention will be described in detail with reference to the following specific examples, and it should be understood that the following specific examples are only for illustrating the present invention and are not intended to limit the scope of the present invention. Additionally, the steps illustrated in the flowcharts of the figures may be performed in a computer system such as a set of computer executable instructions, and although a logical order is illustrated in the flowcharts, in some cases the steps illustrated or described may be performed in an order other than that herein.

The invention provides a non-control automatic management character rolling module realized on an embedded network telephone.

The embedded network phone can provide position coordinate information of the display screen, and a specific text scrolling area can be created on a determined area corresponding to the position coordinate information on the display device by utilizing the information and other additional information. The scroll unit displays the text in the text scroll area. The information contained in the scrolling unit is: information (text, background, etc.), behavior control information, multiplexing inspection information, etc. that need to be scroll-presented; the multiplexing check information refers to coordinate information (i.e. position information), window handle, other status information (e.g. drawing area size) provided by the display system, and the like, and these information are stored for multiplexing the scrolling unit. Multiplexing inspection information is only a definition and does not mean that it can only be used for multiplexing inspection, essentially, the information therein needs to be used at the time of multiplexing inspection, and also needs to be used in creating a scroll unit or other functions. Because the scrolling unit can be multiplexed, when the displayed text changes and other display conditions are unchanged, only the text needs to be directly changed. The plurality of rolling units are connected in series and managed through a data management linked list. When it is desired to display some text information on the phone display device, a scrolling unit is created to save the necessary information.

The behavior control information includes relevant scroll information of the scroll unit such as: scroll speed, direction, state, effect, or other property. Speed and direction are parameter controls. Positive numbers are left directions, negative numbers are right directions (we define an origin in a text scroll area and draw coordinates, the directions are calculated according to the coordinates at the time of final drawing. In this example, the origin is specified to be at the upper left corner of the area, the right is x positive, and the downward is y positive. The state control is function control, and according to the use scene, the function control can be customized, and when in operation, the state (namely the behavior control information) of each rolling unit can be checked, so as to determine whether to operate, pause, restart, destroy, skip and the like; the destroying state can thoroughly destroy the rolling unit from the data management linked list and release occupied resources, and the rolling units with other states can be multiplexed; the skip state may be used in conjunction with speed control to optimize performance. Only the rolling units in the running state can actually draw, so that the rolling units can be set to run at intervals of a plurality of times, and the effects of speed control, performance optimization and the like can be achieved. The effect control is function control, and the function control can be customized according to the use scene, so that the rolling effect is defined, such as rolling from left to right, from right to left, starting from head to tail, starting after the tail disappears, and the like. Specifically, if in horizontal scrolling from right to left, the positional pixel offset at the time of drawing can be defined such that all characters are moved out of the display area, and the pixel offset start of the characters is placed at the character head coordinates in the next timer event, the effect that the characters scroll from the head to the tail and are displayed from the head can be formed. Control of other properties is typically achieved by parameter control such as number of scrolling times, whether drawing is required, when to pause, when to scroll again, etc. The behavior control information is preset, and the function callback can be used in the behavior control, so that the behavior control can be dynamically controlled. When the timer accesses, a preset callback function is called according to the specific situation at the time, and the timer pauses, skips, scrolls again and the like according to the return value (state) of the callback function.

The execution unit is arranged in a timer of the embedded telephone system, the execution unit is awakened each time the timer is reached, the execution unit accesses each rolling unit, extracts information in the rolling unit and behavior control information existing in the rolling unit to conduct rolling display and behavior control of the rolling unit, and the execution unit can conduct behavior updating and judging according to the behavior control information of the rolling unit when executing. The text scrolling is realized by adopting a writing position pixel offset method, namely, text movement is drawn into a temporary memory in a pixel movement mode (as shown in fig. 2), and then an effective area (namely, an area which is expected to be displayed on an interface is drawn into an area indicated by a scrolling unit when the scrolling unit is created, namely, the area is set according to position size information), so that a scrolling effect is formed.

The creation unit is used for creating the rolling unit and checking whether the rolling unit which can be multiplexed exists or not, and when the rolling unit is created, multiplexing check is firstly carried out to confirm whether the specific rolling unit exists or not, and if the specific rolling unit exists, multiplexing is carried out. The identification of the uniquely specified rolling unit is adopted for multiplexing inspection, and the inspected content such as window handle, position information, size information and the like is the same as the information created twice, namely the rolling unit is ready to be created. Related content, such as text, in the scrolling unit can be directly modified during multiplexing, thereby realizing multiplexing. If there is no reusable scroll unit, the scroll unit is newly created and necessary information such as information (text, background, etc.), behavior control information, multiplexing check information, etc. to be scroll-presented is set.

Based on the above module architecture, the invention also provides a non-control automatic management character scrolling method implemented on an embedded network phone, comprising the following steps:

a scroll unit is created, first, it is checked whether there is a scroll unit that can be multiplexed, the unit is multiplexed if there is a multiplexing-possible scroll unit, and if there is no multiplexing-possible unit, a scroll unit is created, necessary information including window information, coordinate information, size information, and various behavior control information is stored in the scroll unit. And organizing the plurality of scrolling units with a linked list.

The scrolling unit is accessed and executed at regular time. The linked list structure entry of the organization rolling unit is in the timer. And accessing each rolling unit in the rolling unit linked list in the system timer, and updating and calculating each rolling unit in each access.

And displaying information on the screen of the embedded network telephone based on the scrolling unit, drawing the text into a temporary memory in a pixel movement mode (as shown in fig. 2) when the text moves, and drawing an effective area into an area indicated by the scrolling unit to form a scrolling effect.

The technical means disclosed by the scheme of the invention is not limited to the technical means disclosed by the embodiment, and also comprises the technical scheme formed by any combination of the technical features. It should be noted that modifications and adaptations to the invention may occur to one skilled in the art without departing from the principles of the present invention and are intended to be within the scope of the present invention.
