  10     @class wxPickerBase
  11     @wxheader{pickerbase.h}
  12
  13     Base abstract class for all pickers which support an auxiliary text control.
  14     This class handles all positioning and sizing of the text control like a
  15     an horizontal wxBoxSizer would do, with the text control on
  16     the left of the picker button.
  17     The proportion (see wxSizer documentation for more info about
  18     proportion values) of the picker control defaults to 1 when there isn't a text
  19     control
  20     associated (see @c wxPB_USE_TEXTCTRL style) and to 0 otherwise.

  22     @beginStyleTable

  24            Creates a text control to the left of the picker which is
  25            completely managed by this wxPickerBase class.

  50         Very important: the contents of the text control could be containing an invalid
  51         representation of the entity which can be chosen through the picker (e.g. the user entered an invalid colour syntax because of a typo). Thus you should never parse the content of the textctrl to get the user's input; rather use the derived-class getter (e.g. wxColourPickerCtrl::GetColour, wxFilePickerCtrl::GetPath, etc).
