C++ (Cpp) Send_LikesClipping Examples

Example #1

File: ResizableLayout.cpp Project: Thomas-Mielke-Software/ECTImport

/*!
 *  This function is used to determine if a control can be safely clipped
 *  out of the parent window client area when it is repainted, usually
 *  after a resize operation.
 *  
 *  @param layout Reference to a @c LAYOUTINFO structure for the control
 *  
 *  @return The return value is @c TRUE if clipping is supported by the
 *          control, @c FALSE otherwise.
 *
 *  @remarks The default implementation tries to identify @a clippable
 *           windows by their class name and window style.
 *        @n Override this function if you need a different behavior or if
 *           you have custom controls that fail to be identified.
