@remarks
- Primary control shall use id wxPG_SUBID1, and secondary (button) control
shall use wxPG_SUBID2.
- - Implementation shoud connect all necessary events to the
- wxPropertyGrid::OnCustomEditorEvent. For Example:
- @code
- // Relays wxEVT_COMMAND_TEXT_UPDATED events of primary editor
- // control to the OnEvent.
- control->Connect(control->GetId(), wxEVT_COMMAND_TEXT_UPDATED,
- wxCommandEventHandler(wxPropertyGrid::OnCustomEditorEvent),
- NULL, propgrid);
- @endcode
- OnCustomEditorEvent will then forward events, first to
- wxPGEditor::OnEvent() and then to wxPGProperty::OnEvent().
+ - Unlike in previous version of wxPropertyGrid, it is no longer
+ necessary to call wxEvtHandler::Connect() for interesting editor
+ events. Instead, all events from control are now automatically
+ forwarded to wxPGEditor::OnEvent() and wxPGProperty::OnEvent().
*/

@remarks wxPropertyGrid will automatically unfocus the editor when
- wxEVT_COMMAND_TEXT_ENTER is received and when it results in
- property value being modified. This happens regardless of
- editor type (ie. behavior is same for any wxTextCtrl and
- wxComboBox based editor).

@class wxPGMultiButton
For instance, here we add three buttons to a TextCtrl editor:
@code

#include <wx/propgrid/editors.h>
class wxSampleMultiButtonEditor : public wxPGTextCtrlEditor
{
- DECLARE_DYNAMIC_CLASS(wxSampleMultiButtonEditor)
+ wxDECLARE_DYNAMIC_CLASS(wxSampleMultiButtonEditor);

+ // Return true if the action modified the value in editor.
+ ...
}

{

- return true;
+ // Do something when the second button is pressed
+ ...
}
if ( event.GetId() == buttons->GetButtonId(2) )

- return true;
+ // Do something when the third button is pressed
+ ...
}
}
return wxPGTextCtrlEditor::OnEvent(propGrid, property, ctrl, event);
}
-
@endcode
Further to use this editor, code like this can be used:
@code
-
// Register editor class - needs only to be called once
wxPGEditor* multiButtonEditor = new wxSampleMultiButtonEditor();
wxPropertyGrid::RegisterEditorClass( multiButtonEditor );
// Change property to use editor created in the previous code segment
propGrid->SetPropertyEditor( "MultipleButtons", multiButtonEditor );
