Introduction
This is a template class for creating hovering controls. It uses the _TrackMouseEvent method to recieve notifications regarding mouse events.
Using the code
To use it, you need to create a new class derived from the desired type (CButton, CEdit ...) and add the template code there. You also need to override 2 pure virtual functions: OnOverEnter() and OnHoverLeave(). Your class receives notifications via those functions. There is also a function called IsHover() which can return the hovering state.
In the demo project, I've created 2 simple classes: One derived from CButton and the other one derived from CEdit. They both react to mouse events.
#include "TrackControl.h"
class CHoverButton : public CTrackControl<CButton>
{
public:
virtual void OnHoverEnter()
{
Invalidate();
}
virtual void OnHoverLeave()
{
Invalidate();
}
}
