Member Function Documentation

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
dcwxDC to paint on.
rectBox reserved for custom graphics. Includes surrounding rectangle, if any. If x is < 0, then this is a measure item call (see above).
paintdatawxPGPaintData structure with much useful data about painted item.
{
// 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.

ValueToString()

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
itemNormally -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 wxDefaultSize.

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 (i.e. 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.
