YOU MUST USE A wxWIDGETS RELEASE NEWER THAN 1/29/05 - AFTER POPUPWINDOW FIX
DropDownBase is a class that has a DropDownPopup as a child. It works like a
wxComboBox in that there is a button to the right that you use to drop down
a window. You can put whatever you want in the DropDownPopup by calling
GetPopupWindow()->SetChild(win) in your DoShowPopup function.
Additionally, you'll want to put a window to the left of the dropdown button.
You need to subclass this to make a new control.
You need to override these function in DropDownBase
DoGetBestSize() let wxWidgets know how big this control wants to be
DoGetBestDropHeight(max) - max is the # pixels to bottom of screen, you probably want
it smaller so return that height, return -1 if you don't want the popup shown.
DoShowPopup() - this is called from ShowPopup after creating the m_popupWin.
Create your child window with the popup as the parent and call
GetPopupWindow()->SetChild(win). Make sure you call
DropDownBase::DoShowPopup() to have the popup window shown.
