PAINTCALLBACK_POSTPAINT Function

#include "l_bitmap.h"

L_INT pEXT_CALLBACK YourFunction(pDisplay, pBitmap, pUserData)

This callback can be used to free any memory allocated in PAINTCALLBACK_PREPAINT.

Parameters

L_VOID *pDisplay

Handle of the device context passed to the paint function.

pBITMAPHANDLE pBitmap

Pointer to the bitmap handle structure holding the input data.

L_VOID *pUserData

Void pointer that you can use to access a variable or structure containing data that your callback function needs. This gives you a way to receive data indirectly from the function that uses this callback function. (This is the same pointer that you pass in the pUserData parameter of the PAINTCALLBACKDATA structure.)

Returns

Value	Meaning
SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

Comments

pDisplay is the pDisplay member from the PAINTCALLBACKDATA structure that you passed to the paint function. The default callbacks expect it to be a HDC handle. But, if you override all the paint callbacks, it can be a pointer of any type you want.

This callback is called after all other paint callbacks. This callback will be called exactly once for a paint operation.

You can use this callback to perform any device un-initialization or free any memory allocated in the PAINTCALLBACK_PREPAINT callback.
