Draws only the selected item(s) on layer that are within a defined extent.
// Java public bool DrawSelectedEx( TGIS_Extent _extent );
// Oxygene public function DrawSelectedEx( _extent : TGIS_Extent ) : Boolean; override;
|_extent||TGIS_Extent||extent to be drawn|
| bool |
|True if draw was performed|
Use this method to draw a layer. Normally this method is called by Paint.
When using this operation, never call any function which uses FindFirst..FindNext (i.e., any function which iterates through the shapes using it). So never use inside an operation like Locate, PaintScope etc.
See Paint for example.
