Detailed Description

The technical solutions provided by the present invention will be described in detail below with reference to specific examples, and it should be understood that the following specific embodiments are only illustrative of the present invention and are not intended to limit the scope of the present invention. Additionally, the steps illustrated in the flow charts 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 flow charts, in some cases, the steps illustrated or described may be performed in an order different than here.

The invention provides a non-control automatic management character rolling module realized on an embedded network phone, which structurally comprises a rolling unit, an execution unit and a creation unit.

The embedded network phone can provide the position coordinate information of the display screen, and a specific character rolling area can be created on the determined area corresponding to the position coordinate information on the display device by utilizing the information and other additional information. The scrolling unit displays the character scroll area. The information contained in the scroll unit is: information (text, background, etc.) that needs to be presented in a scrolling manner, behavior control information, multiplexing inspection information, etc.; the multiplexing check information refers to coordinate information (i.e., position information) provided by the display system, window handles, other state information (e.g., drawing area size), etc., which are stored for multiplexing of the scrolling unit. The multiplexing check information is merely a definition, and does not mean that it can be used only for multiplexing check, and in essence, the information therein needs to be used at the time of multiplexing check, and also needs to be used in creating a scrolling unit or other functions. Since the scrolling unit can be multiplexed, when the displayed text changes and other display conditions do not change, 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 some character information needs to be displayed on the phone display equipment, a rolling unit is created, and necessary information is stored.

The behavior control information includes related scroll information of the scroll unit, such as: scrolling speed, direction, status, effect, or other property. Speed and direction are parameter controls. In the present example, the origin is defined at the upper left corner of the region, x positive is right, and y positive is downward. The state control is function control, the function control can be customized according to a use scene, and when the system runs, the state (namely behavior control information) of each rolling unit can be checked, so that whether the system runs, pauses, restarts, destroys, skips and the like is determined; the destruction state can thoroughly destroy the rolling unit from the data management linked list and release occupied resources, and the rolling units in other states can be reused; the skip state may be used in conjunction with speed control to optimize performance. Only the rolling unit in the running state can be really drawn, so that the rolling unit can be set to run at intervals, 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 from left to right, from right to left, from head to tail, and then starting after the rolling disappears. Specifically, as in horizontal right-to-left scrolling, the positional pixel offset at the time of drawing may be specified such that all the text moves out of the display area and the pixel offset of the text is initially placed at the head coordinates of the text in the next timer event, and then an effect may be created in which the text disappears from the head to the tail, and starts to be displayed from the head here. Control of other properties is typically achieved by parameter control, such as the number of scrolls, whether or not drawing is required, when to pause, when to scroll again, and so on. The behavior control information is preset, and function call-back can be used in behavior control, so that dynamic control can be realized. When the timer is accessed, a preset callback function is called according to the specific situation at that time, and pause, skip, re-scroll and the like are carried out according to the return value (state) of the callback function.

The execution unit is arranged in a timer of the embedded phone system, wakes up the execution unit when the timer arrives, accesses each rolling unit, extracts information in the rolling unit and behavior control information existing in the rolling unit to perform rolling display and behavior control on the rolling unit, and performs behavior updating and judgment according to the behavior control information of the rolling unit when the execution unit executes. The character scrolling is realized by adopting a method of writing position pixel shift, namely, the text movement is drawn into a temporary memory (as shown in fig. 2) in a pixel movement mode, and then an effective area (namely, an area expected to be displayed on an interface, and the area is set according to position size information when a scrolling unit is created) is drawn into an area indicated by the scrolling unit, so that a scrolling effect is formed.

The creation unit is used for creating the rolling unit and checking whether the rolling unit capable of being reused exists, when the rolling unit is created, multiplexing check is firstly carried out to confirm whether the specific rolling unit already exists, and if the specific rolling unit exists, the specific rolling unit is reused. The multiplexing check is carried out by using the identifier which can uniquely specify the scroll unit, the checked contents such as window handle, position information, size information and the like are the same as those created twice, namely, the scroll unit is considered to be the same scroll unit to be created. When in multiplexing, related contents in the rolling unit, such as a word scene, can be directly modified, thereby realizing multiplexing. If no reusable scroll unit exists, the scroll unit is newly created, and necessary information such as information (characters, background and the like) needing to be scrolled and presented, behavior control information, multiplexing check information and the like is set.

Based on the module architecture, the invention also provides a method for realizing the automatic management of the characters rolling by the non-control on the embedded network phone, which comprises the following steps:

and creating a rolling unit, firstly checking whether a reusable rolling unit exists or not, if the reusable rolling unit exists, multiplexing the unit, and if the reusable rolling unit does not exist, creating the rolling unit, and storing necessary information in the rolling unit, wherein the necessary information comprises window information, coordinate information, size information and various behavior control information. And organizing the plurality of scrolling elements with a linked list.

The scrolling unit may be accessed and executed periodically. The linked list structure entry for organizing the rolling elements 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.

The information is displayed on the screen of the embedded network phone based on the scrolling unit, the text is drawn into a temporary memory (as shown in fig. 2) in a pixel moving mode when moving, and then an effective area is drawn into an area indicated by the scrolling unit to form a scrolling effect.

The technical means disclosed in the invention scheme are not limited to the technical means disclosed in the above embodiments, but also include the technical scheme formed by any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present invention, and such improvements and modifications are also considered to be within the scope of the present invention.
