// ComboBox, CheckBox, TextCtrlAndButton, and ChoiceAndButton. Additional
|

// editors include SpinCtrl and DatePickerCtrl, but using them requires
|
|
// calling wxPropertyGrid::RegisterAdditionalEditors() prior use.
|
|
// - Pointer to builtin editor is available as wxPGEditor_EditorName
|
|
// (e.g. wxPGEditor_TextCtrl).
|
|
// - To add new editor you need to register it first using static function
|
|
// wxPropertyGrid::RegisterEditorClass(), with code like this:
|
|
// wxPGEditor *editorPointer = wxPropertyGrid::RegisterEditorClass(
|
|
// new MyEditorClass(), "MyEditor");
|
|
// After that, wxPropertyGrid will take ownership of the given object, but
|
|
// you should still store editorPointer somewhere, so you can pass it to
|
|
// wxPGProperty::SetEditor(), or return it from
|
|
// wxPGEditor::DoGetEditorClass().
