## Detailed Description

This class can be used to have multiple buttons in a property editor.

You will need to create a new property editor class, override CreateControls, and have it return wxPGMultiButton instance in wxPGWindowList::SetSecondary().

For instance, here we add three buttons to a TextCtrl editor:

        #include <wx/propgrid/editors.h>

        class wxSampleMultiButtonEditor : public wxPGTextCtrlEditor
        {
            wxDECLARE_DYNAMIC_CLASS(wxSampleMultiButtonEditor);

        public:
            wxSampleMultiButtonEditor() {}
            virtual ~wxSampleMultiButtonEditor() {}

            virtual wxString GetName() const { return "SampleMultiButtonEditor"; }

            virtual wxPGWindowList CreateControls( wxPropertyGrid* propGrid,
                                                   wxPGProperty* property,
                                                   const wxPoint& pos,
                                                   const wxSize& sz ) const;
            virtual bool OnEvent( wxPropertyGrid* propGrid,
                                  wxPGProperty* property,
                                  wxWindow* ctrl,
                                  wxEvent& event ) const;
        };

        wxIMPLEMENT_DYNAMIC_CLASS(wxSampleMultiButtonEditor, wxPGTextCtrlEditor);

        wxPGWindowList wxSampleMultiButtonEditor::CreateControls( wxPropertyGrid* propGrid,
                                                                  wxPGProperty* property,
                                                                  const wxPoint& pos,
                                                                  const wxSize& sz ) const
        {
            // Create and populate buttons-subwindow
            wxPGMultiButton* buttons = new wxPGMultiButton( propGrid, sz );

            // Add two regular buttons
            buttons->Add( "..." );
            buttons->Add( "A" );
            // Add a bitmap button
            buttons->Add( wxArtProvider::GetBitmap(wxART_FOLDER) );

            // Create the 'primary' editor control (textctrl in this case)
            wxPGWindowList wndList = wxPGTextCtrlEditor::CreateControls
                                     ( propGrid, property, pos,
                                       buttons->GetPrimarySize() );

            // Finally, move buttons-subwindow to correct position and make sure
            // returned wxPGWindowList contains our custom button list.
            buttons->Finalize(propGrid, pos);

            wndList.SetSecondary( buttons );
            return wndList;
        }

        bool wxSampleMultiButtonEditor::OnEvent( wxPropertyGrid* propGrid,
                                                 wxPGProperty* property,
                                                 wxWindow* ctrl,
                                                 wxEvent& event ) const
        {
            if ( event.GetEventType() == wxEVT_COMMAND_BUTTON_CLICKED )
            {
                wxPGMultiButton* buttons = (wxPGMultiButton*) propGrid->GetEditorControlSecondary();

                if ( event.GetId() == buttons->GetButtonId(0) )
                {
                    // Do something when the first button is pressed
                    // Return true if the action modified the value in editor.
                    ...
                }
                if ( event.GetId() == buttons->GetButtonId(1) )
                {
                    // Do something when the second button is pressed
                    ...
                }
                if ( event.GetId() == buttons->GetButtonId(2) )
                {
                    // Do something when the third button is pressed
                    ...
                }
            }
            return wxPGTextCtrlEditor::OnEvent(propGrid, property, ctrl, event);
        }

Further to use this editor, code like this can be used:

            // Register editor class - needs only to be called once
            wxPGEditor* multiButtonEditor = new wxSampleMultiButtonEditor();
            wxPropertyGrid::RegisterEditorClass( multiButtonEditor );

            // Insert the property that will have multiple buttons
            propGrid->Append( new wxLongStringProperty("MultipleButtons", wxPG_LABEL) );

            // Change property to use editor created in the previous code segment
            propGrid->SetPropertyEditor( "MultipleButtons", multiButtonEditor );
