/*
wxCustomButton is a bitmap and/or text button that can toggle or not.
It can be used as a drop-in replacement for a wxButton, wxToggleButton,
wxBitmapButton, and the non-existant "wxBitmapToggleButton."
The event's wxCommandEvent::GetExtraLong contains one of the following
wxEVT_LEFT_UP, wxEVT_RIGHT_UP, wxEVT_LEFT_DCLICK, wxEVT_RIGHT_DCLICK
these can be used to distinguish between the types of events sent
There are four styles the button can take.
wxCUSTBUT_BUTTON == wxButton
Left and Right clicks and double clicks all send
wxEVT_COMMAND_BUTTON_CLICKED => EVT_BUTTON(id,fn)
wxCUSTBUT_TOGGLE == wxToggleButton
Left clicks sends
wxEVT_COMMAND_TOGGLEBUTTON_CLICKED => EVT_TOGGLEBUTTON(id, fn)
Left double clicks and Right clicks send
wxEVT_COMMAND_BUTTON_CLICKED => EVT_BUTTON(id,fn)
wxCUSTBUT_BUT_DCLICK_TOG
Left and Right clicks and Right double clicks send
wxEVT_COMMAND_BUTTON_CLICKED => EVT_BUTTON(id,fn)
Left double clicks sends
wxEVT_COMMAND_TOGGLEBUTTON_CLICKED => EVT_TOGGLEBUTTON(id, fn)
wxCUSTBUT_TOG_DCLICK_BUT
Left clicks sends
wxEVT_COMMAND_TOGGLEBUTTON_CLICKED => EVT_TOGGLEBUTTON(id, fn)
Left and Right double clicks and Right clicks send
wxEVT_COMMAND_BUTTON_CLICKED => EVT_BUTTON(id,fn)
The event's wxCommandEvent::GetInt (IsChecked) is true (1) if the button is
depressed, this is only useful for the wxToggleButton styles
For both types of button when double-clicked it sends this event
wxEVT_COMMAND_BUTTON_CLICKED => EVT_BUTTON(id, fn)
and the button state does not change. Only a single EVT_BUTTON event should
be sent on double-click and event.GetExtraLong == wxEVT_XXX_DCLICK,
if not then there's a bug.
If no bitmaps are set the text is centered, if only a bitmap it set then
it's centered, if a bitmap and text are set then the text is one of the
positions wxCUSTBUT_LEFT/RIGHT/TOP/BOTTOM
The disabled bitmap it automatically created by dithering with the background,
the others just copy the bitmap in the constructor. The control assumes they
are all the same size.
You have to #include "wx/tglbtn.h" for EVT_TOGGLEBUTTON
