Example
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.
#include <ltwrappr.h> //Required by all classes #include <ltlck.h> //Unlock support L_VOID TestFunction(HWND hWndParent) { LBase::LoadLibraries(LT_ALL_LEADLIB); //make sure all libraries are loaded LAnimationWindow MyAnimation; WRPUNLOCKSUPPORT(); //Set auto loop to TRUE MyAnimation.EnableLoop(); MyAnimation.SetFileName(TEXT("eye.gif")); if (MyAnimation.Load()!=SUCCESS) { MessageBox(hWndParent, TEXT("Error loading file!"),TEXT("Sample"), MB_OK|MB_ICONSTOP); return; } MyAnimation.CreateWnd(hWndParent,0, WS_VISIBLE|WS_CHILD|WS_BORDER,0,0,300,300); MyAnimation.PlayAnimation(); while (MyAnimation.IsPlaying()) { L_BOOL bCanceled; L_BOOL bQuit = MyAnimation.DoEvents(&bCanceled); if (bCanceled || bQuit) { MyAnimation.StopAnimation(); break; } } }
