L_LTZMV_API L_INT L_DestroyZoomView(hWnd, uIndex)
Destroys the specified Zoom View, and releases all resources associated with it. Call this function before destroying the window.
Handle to a window.
Index of the zoomed view to be destroyed. This is a zero-based index.
Value | Meaning |
---|---|
SUCCESS | The function was successful. |
< 1 | An error occurred. Refer to Return Codes. |
When a zoomed view is no longer needed, call the L_DestroyZoomView function to stop the specified Zoom View procedure and to detach it from the window handle.
You must call this function for each Zoom View you have created before destroying the window with which the Zoom Views are associated.
If you need to destroy all the zoomed views that are attached to a specified window, destroy them from the last Zoom View to the first Zoom View. For example, if you have five Zoom Views associated with the specified window you need to do the following:
L_UINT uCount,i;
L_GetZoomViewsCount(hWnd,&uCount);
for(i=0; i < uCount; ++i)
{
L_DestroyZoomView(hWnd,uCount-i-1);
}
