Define Documentation

#define WX_PG_CLASSINFO

(

NAME

)

(&NAME::ms_classInfo)

Use this with wxPropertyGrid::IsPropertyKindOf.

For example, as in

        pg->IsPropertyKindOf(WX_PG_CLASSINFO(wxStringProperty))

Typedef Documentation

typedef void(* wxPGPaintCallback)(wxPGProperty *property, wxDC &dc, const wxRect &rect, wxPGPaintData &paintdata)

This callback function is used by atleast wxCustomProperty to facilitiate drawing items in drop down list.

Works very much like the old wxPGProperty::OnCustomPaint.

typedef int(* wxPGSortCallback)(wxPropertyGrid *propGrid, wxPGProperty *p1, wxPGProperty *p2)

This callback function is used for sorting properties.

Call wxPropertyGrid::SetSortFunction() to set it.

This function should return a value greater than 0 if position of p1 is after p2. So, for instance, when comparing property names, you can use following implementation:

            int MyPropertySortFunction(wxPropertyGrid* propGrid,
                                       wxPGProperty* p1,
                                       wxPGProperty* p2)
            {
                return p1->GetBaseName().compare( p2->GetBaseName() );
            }

typedef bool(* wxPropertyGridCallback)(wxPropertyGrid *propGrid, wxPGProperty *property, wxWindow *ctrl, int data)

This callback function is used by atleast wxCustomProperty to facilitiate easy custom action on button press.

Parameters:

	propGrid	related wxPropertyGrid
	property	related wxPGProperty
	ctrl	If not NULL (for example, not selected), a wxWindow* or equivalent
	data	Value depends on the context.

Return values:

True

if changed value of the property.
