L_INT LAnimationWindow::PlayAnimation()
Starts an animation playback.
Value | Meaning |
---|---|
SUCCESS | The function was successful. |
< 1 | An error occurred. Refer to Return Codes. |
This function starts an animation playback. In order to play an animation, you must call LAnimationWindow::Load or LAnimationWindow::SetBitmapList prior to calling this function. You can also pass an LBitmapList object using the constructor.
If the animation is already started, the function will return WRPERR_ANIMATION_ALREADY_STARTED.
If the loaded file is not a valid file, the return value will be WRPERR_ANIMATION_INVALID_FILE.
Win32, x64.
The following example will create an animation, and play it continuously
until the user aborts or closes the program.
The program uses DoEvents to allow the user to stop animation.
L_INT LAnimationWindow_PlayAnimationExample(HWND hWndParent)
{
L_INT nRet;
LBase::LoadLibraries(LT_ALL_LEADLIB);
//make sure all libraries are loaded
LAnimationWindow MyAnimation;
//Set auto loop to TRUE
MyAnimation.EnableLoop();
MyAnimation.SetFileName(MAKE_IMAGE_PATH(TEXT("eye.gif")));
nRet = MyAnimation.Load();
if (nRet!=SUCCESS)
{
MessageBox(hWndParent, TEXT("Error loading file!"),TEXT("Sample"), MB_OK|MB_ICONSTOP);
return nRet;
}
MyAnimation.CreateWnd(hWndParent,0, WS_VISIBLE|WS_CHILD|WS_BORDER,0,0,300,300);
nRet = MyAnimation.PlayAnimation();
if(nRet != SUCCESS)
return nRet;
while (MyAnimation.IsPlaying())
{
L_BOOL bCanceled;
L_BOOL bQuit = MyAnimation.DoEvents(&bCanceled);
if (bCanceled || bQuit)
{
MyAnimation.StopAnimation();
break;
}
}
return SUCCESS;
}
