DocStr(wxPyComboCtrl,
"A combo control is a generic combobox that allows for a totally custom
popup. In addition it has other customization features. For instance,
position and size of the dropdown button can be changed.

To specify what to use for the popup control you need to derive a
class from `wx.combo.ComboPopup` and pass it to the ComboCtrl with
`SetPopupControl`.  It doesn't derive from any widget class so it can
be used either as a mixin class combined with some standard or custom
widget, or you can use the derived ComboPopup to create and hold an
independent reference to the widget to be used for the popup.
", "

Window Styles
-------------
    ====================   ============================================
    wx.CB_READONLY         Text will not be editable.
    wx.CB_SORT             Sorts the entries in the list alphabetically.
    wx.TE_PROCESS_ENTER    The control will generate the event
                           EVT_TEXT_ENTER (otherwise pressing Enter key
                           is either processed internally by the control
                           or used for navigation between dialog controls).
    wx.CC_SPECIAL_DCLICK   Double-clicking triggers a call to popup's
                           OnComboDoubleClick. Actual behaviour is defined
                           by a derived class. For instance,
                           OwnerDrawnComboBox will cycle an item. This
                           style only applies if wx.CB_READONLY is used
                           as well.
    wx.CC_STD_BUTTON       Drop button will behave more like a standard
                           push button.
