Message1. wxWindow, Image

Hi,
I search a function that indicates to me if my mouse event appends in my image (that I have drawn with a OnDraw method) or outside my image.
thank you

Hi!
I guess you'll have multiple choices. Well, at least two :)
1. Let the toplevel window (on which you paint the image) handle wxMouseEvents.
2. Write a "Canvas" (like a panel where you draw on) class and let this window handle the events.

1. I wouldn't recommend that solution. You'd have to get and inspect the XY coordinates to see if the mouse was inside your image.
2. Write a wxPanel derived Canvas class, resize it to the image size, let it handle EVT_ENTER_WINDOW and EVT_LEAVE_WINDOW events. That way you'll know if the mouse is over your image or not.
