Accessing GetValue() from wxWindow class

Is there any way to access the GetValue() member of a GUI control under wxWidgets, if it is declared as a wxWindow rather than a wxCheckBox or wxRa开发者_如何学PythondioButton etc? Thanks.

An object declared as WxWindow is NOT a GUI control. A pointer declared as a WxWindow* might point to a wxStaticText object or a wxCheckBox object. You'd have to do a dynamic_cast< > to find out. Once you know it's a wxCheckBox, you can call wxCheckBox::GetValue. Similarly, if it's a wxRadioButton, you can call wxRadioButton::GetValue.

Note that per C++ rules, wxCheckBox::GetValue and wxRadioButton::GetValue are entirely unrelated. They just happen to have the same method name.

You can't call a derivative's function from a base pointer unless it's through a virtual function call, so no.

You can downcast though and get access to that function.
