@class wxPopupWindow
A special kind of top level window used for popup menus,
combobox popups and such.
@beginStyleTable
@style{wxPU_CONTAINS_CONTROLS}
By default in wxMSW, a popup window will not take focus from its parent
window. However many standard controls, including common ones such as
wxTextCtrl, need focus to function correctly and will not work when
placed on a default popup. This flag can be used to make the popup take
focus and let all controls work but at the price of not allowing the
parent window to keep focus while the popup is shown, which can also be
sometimes desirable. This style is currently only implemented in MSW
and simply does nothing under the other platforms (it's new since
wxWidgets 3.1.3).
