A size event holds information about size change events.

The EVT_SIZE handler function will be called when the window has been resized.

You may wish to use this for frames to resize their child windows as appropriate.

Note that the size passed is of the whole window: call Window#get_client_size for the area which may be used by the application.

When a window is resized, usually only a small part of the window is damaged and you may only need to repaint that area. However, if your drawing depends on the size of the window, you may need to clear the DC explicitly and repaint the whole window. In which case, you may need to call Window#refresh to invalidate the entire window.
