Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.
Embedded device provided by the invention shows waits for that cartoon method can be applicable on the embedded device that adopts the DirectFB shape library, on embedded devices such as hand-held mobile terminal, IPTV set-top box, Web TV and numerically-controlled machine.See also Fig. 1, wait for the cartoon method process flow diagram for embedded device in the preferred embodiment of the present invention shows.As shown in Figure 1, method provided by the invention may further comprise the steps:
In steps A, obtain system state, execution in step B when executing the task in system is at the interrupt step B when finishing that executes the task of system.
In step B, utilize the DirectFB shape library of embedded device and the API that the Lite widget library provides, show default set of diagrams sheet successively according to setting speed.
In said process, steps A is ongoing, judges constantly that promptly whether system carries out corresponding task on the backstage, and whether the user is in waiting status, thereby shows execution in step B when waiting for animation at needs.Equally, execute the task to finish promptly in system and finish to wait the interrupt step B that bides one's time, to carry out follow-up demonstration.
See also Fig. 2, embedded device shows the particular flow sheet of waiting for step B in the cartoon method in the preferred embodiment of the present invention.As shown in Figure 2, the specific implementation process of step B is as follows:
In step B1, create the animation window thread.
In step B2, utilize the DirectFB shape library of embedded device and API establishment animation window that the Lite widget library provides and the control that loads picture.In a preferred embodiment of the invention, this step B2 can also comprise background and the transparency that window is set.
In step B3, in the window of creating, carry out animation display.
In a preferred embodiment of the invention, this method also comprises default step B0: deposit in embedded device as the set of diagrams sheet of waiting for animation.Therefore, step B3 further comprises: step B31, transfer default set of diagrams sheet; B32, show the picture of transferring successively according to setting speed.
In a preferred embodiment of the invention, behind interrupt step B, also will destroy window and thread.
Below the main code that the present invention is based on the DirectFB shape library is described.
1, in step B1, create the animation window thread:
pWaitWinThread＝direct_thread_create(DTT_MESSAGING，kkWaitWinEventThread，pSearchApWaitTips，″Wait?Window″)；
2, in step B2, create the control of animation window and loading picture:
lite_new_window(NULL，&rect，DWCAPS_ALPHACHANNEL，
liteDefaultWindowTheme，″″，&window)；
res＝lite_new_image(LITE_BOX(window)，&rect，NULL，&pAniImage)；
if(res?！＝DFB_OK)
{
_PRINT_NANXQ(″fail?to?create?lite_new_image！\n.″)；
}
res＝lite_load_image(pAniImage，
SHAREPICTURESDIR″/kktips_wait.png″)；
3, in step B3, carry out animation display:
Char*animationPics[12]=...; The preservation position of // continuous picture
while(WaitWinExitFlag＝＝false)
{
usleep(500000)；
// calculate to show any pictures; Cnt is the array index that Shows Picture
cnt＝cnt％12；
res＝lite_load_image(pAniImage，animationPics[cnt])；
if(res！＝DFB_OK)
{
print(″lite_load_image?execute?fail.\n″)；
}
cnt++；
break；
}
4, withdraw from animation display, destroy the animation display window:
if(WaitWinExitFlag＝＝true)
{
break；
}
kkDestroyWaitWin()；
See also Fig. 3, show the module diagram of the system that waits for animation for embedded device in the preferred embodiment of the present invention.As shown in Figure 3, embedded device provided by the invention shows the system that waits for animation, comprises interrupt module 100 and animation display module 200.Wherein, interrupt module 100 is used to obtain system state and opens animation display module 200 when executing the task in system, executes the task in system and interrupts animation display module 200 when finishing.Animation display module 200 is utilized the DirectFB shape library of embedded device and the API that the Lite widget library provides, and shows default set of diagrams sheet successively according to setting speed.In a preferred embodiment of the invention, this system also comprises the memory module 300 that links to each other with the animation display module, is used to store default set of diagrams sheet.
In sum, the present invention at first needs the art designing to draw the continuous picture of one group of relevant action and deposits in the memory module of embedded device, when switching according to certain speed when Showing Picture, just produces animation effect.In order to show animation synchronously, need newly set up a new thread, the basic API that in thread, uses DirectFB shape library and Lite widget library to provide, set up earlier one with the picture that will load window of a size, set the background and the transparency of window, display speed according to prior setting loads background picture in proper order, has just formed the animation display effect.When the system finishing busy condition, stop animation display, and destroy window and destroy thread.
The present invention can be used as when one independently algoritic module realizes that system need wait for that resource can not enter into new interface to carrying out interface operation as the user, present wait for animation with the prompting custom system be in busy in, thereby the visual perception who strengthens the user experiences, and system to take resource less.
The present invention is described according to specific embodiment, but it will be understood by those skilled in the art that when not breaking away from the scope of the invention, can carry out various variations and be equal to replacement.In addition, for adapting to the specific occasion or the material of the technology of the present invention, can carry out many modifications and not break away from its protection domain the present invention.Therefore, the present invention is not limited to specific embodiment disclosed herein, and comprises that all drop into the embodiment of claim protection domain.
