#include <wx/event.h>
A size event holds information about size change events of wxWindow.
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 wxWindow::GetClientSize() 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 wxWindow::Refresh to invalidate the entire window.
The following event handler macros redirect the events to member function handlers 'func' with prototypes like:
Event macros:
wxEVT_SIZE
event. Public Member Functions | |
wxSizeEvent (const wxSize &sz, int id=0) | |
Constructor. | |
wxSize | GetSize () const |
Returns the entire size of the window generating the size change event. |
wxSizeEvent::wxSizeEvent | ( | const wxSize & | sz, | |
int | id = 0 | |||
) |
Constructor.
wxSize wxSizeEvent::GetSize | ( | ) | const |
Returns the entire size of the window generating the size change event.
This is the new total size of the window, i.e. the same size as would be returned by wxWindow::GetSize() if it were called now. Use wxWindow::GetClientSize() if you catch this event in a top level window such as wxFrame to find the size available for the window contents.
