.SH NAME
wxSizeEvent \- Functions for wxSizeEvent class
.SH DESCRIPTION
.LP
A size event holds information about size change events of \fIwxWindow\fR\&\&.
.LP
The EVT_SIZE handler function will be called when the window has been resized\&.
.LP
You may wish to use this for frames to resize their child windows as appropriate\&.
.LP
Note that the size passed is of the whole window: call \fIwxWindow:getClientSize/1\fR\& for the area which may be used by the application\&.
.LP
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 \fIwxWindow:refresh/2\fR\& to invalidate the entire window\&.
.LP
\fIImportant\fR\& : Sizers ( see overview_sizer ) rely on size events to function correctly\&. Therefore, in a sizer-based layout, do not forget to call Skip on all size events you catch (and don\&'t catch size events at all when you don\&'t need to)\&.
.LP
See: {Width,Height}, Overview events 
.LP
This class is derived (and can use functions) from: \fIwxEvent\fR\&

.LP
Use \fIwxEvtHandler:connect/3\fR\& with \fIwxSizeEventType\fR\& to subscribe to events of this type\&.

.LP
Returns the entire size of the window generating the size change event\&.
.LP
This is the new total size of the window, i\&.e\&. the same size as would be returned by \fIwxWindow:getSize/1\fR\& if it were called now\&. Use \fIwxWindow:getClientSize/1\fR\& if you catch this event in a top level window such as \fIwxFrame\fR\& to find the size available for the window contents\&.
