@brief Base for property editor classes.
|
|
@remarks
|
|
- Event handling:
|
|
wxPGEditor::CreateControls should Connect all necessary events to the
|
|
wxPropertyGrid::OnCustomEditorEvent. For Example:
|
|
@code
|
|
// Relays wxEVT_COMMAND_TEXT_UPDATED events of primary editor
|
|
// control to the OnEvent.
|
|
// NOTE: This event in particular is actually automatically conveyed, but
|
|
// it is just used as an example.
|
|
propgrid->Connect( wxPG_SUBID1, wxEVT_COMMAND_TEXT_UPDATED,
|
|
(wxObjectEventFunction) (wxEventFunction) (wxCommandEventFunction)
|
|
&wxPropertyGrid::OnCustomEditorEvent );
|
|
@endcode
|
|
OnCustomEditorEvent will then forward events, first to wxPGEditor::OnEvent
|
|
and then to wxPGProperty::OnEvent.
|
|
- You need to call macro wxPGRegisterEditorClass(EditorName) before using a custom editor class.
|
|
- See propgrid.cpp for how builtin editors works (starting from wxPGTextCtrlEditor).
