virtual void wxImageFileProperty::OnCustomPaint	(	wxDC &	dc,
		const wxRect &	rect,
		wxPGPaintData &	paintdata
	)

virtual

Override to paint an image in front of the property value text or drop-down list item (but only if wxPGProperty::OnMeasureImage is overridden as well).

If property's OnMeasureImage() returns size that has height != 0 but less than row height ( < 0 has special meanings), wxPropertyGrid calls this method to draw a custom image in a limited area in front of the editor control or value text/graphics, and if control has drop-down list, then the image is drawn there as well (even in the case OnMeasureImage() returned higher height than row height).

NOTE: Following applies when OnMeasureImage() returns a "flexible" height ( using wxPG_FLEXIBLE_SIZE(W,H) macro), which implies variable height items: If rect.x is < 0, then this is a measure item call, which means that dc is invalid and only thing that should be done is to set paintdata.m_drawnHeight to the height of the image of item at index paintdata.m_choiceItem. This call may be done even as often as once every drop-down popup show.

Parameters

dc	wxDC to paint on.
rect	Box reserved for custom graphics. Includes surrounding rectangle, if any. If x is < 0, then this is a measure item call (see above).
paintdata	wxPGPaintData structure with much useful data about painted item. struct wxPGPaintData { // wxPropertyGrid. const wxPropertyGrid* m_parent; // Normally -1, otherwise index to drop-down list item that has to be drawn. int m_choiceItem; // Set to drawn width in OnCustomPaint (optional). int m_drawnWidth; // In a measure item call, set this to the height of item at m_choiceItem index int m_drawnHeight; };

Remarks

You can actually exceed rect width, but if you do so then paintdata.m_drawnWidth must be set to the full width drawn in pixels.
Due to technical reasons, rect's height will be default even if custom height was reported during measure call.
Brush is guaranteed to be default background colour. It has been already used to clear the background of area being painted. It can be modified.
Pen is guaranteed to be 1-wide 'black' (or whatever is the proper colour) pen for drawing framing rectangle. It can be changed as well.

Reimplemented from wxPGProperty.

virtual wxSize wxImageFileProperty::OnMeasureImage ( int item ) const

virtual

Returns size of the custom painted image in front of property.

This method must be overridden to return non-default value if OnCustomPaint is to be called.

Parameters

item	Normally -1, but can be an index to the property's list of items.

Remarks

Default behaviour is to return wxSize(0,0), which means no image.
Default image width or height is indicated with dimension -1.
You can also return wxPG_DEFAULT_IMAGE_SIZE which equals wxSize(-1, -1).

Reimplemented from wxPGProperty.

virtual void wxImageFileProperty::OnSetValue ( )

virtual

This virtual function is called after m_value has been set.

Remarks

If m_value was set to Null variant (ie. unspecified value), OnSetValue() will not be called.
m_value may be of any variant type. Typically properties internally support only one variant type, and as such OnSetValue() provides a good opportunity to convert supported values into internal type.
Default implementation does nothing.
