Functions for wxSizeEvent class
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/1
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/2
to
invalidate the entire window.
Important
: 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).

This class is derived (and can use functions) from: wxEvent

Events
Use wxEvtHandler:connect/3
with wxSizeEventType
to
subscribe to events of this type.
Summary
Functions
Returns the entire size of the window generating the size change event.
Types
Functions
-spec getRect(This) -> {X :: integer(), Y :: integer(), W :: integer(), H :: integer()} when This :: wxSizeEvent().
-spec getSize(This) -> {W :: integer(), H :: integer()} when This :: wxSizeEvent().
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/1
if it were called now. Use
wxWindow:getClientSize/1
if you catch this event in a top level window such as
wxFrame
to find the size available for the window contents.
