/*
|
|
|
|
wxBitmapComboBox is a wxComboBox widget for bitmaps
|
|
|
|
You Append some bitmaps either individually or with an array. Since bitmaps are
|
|
refed this should be a fast process and you don't have to keep them around.
|
|
The size of the items is calculated from the max bitmap and max label so that
|
|
they will all line up nicely.
|
|
|
|
It acts just like a wxComboBox otherwise, sends a EVT_COMBOBOX when selections
|
|
are made with either the mouse on the pulldown list or by pressing the up/down
|
|
arrows.
