Hi @all.

I need to fill polygons with a hatching (eg BrushStyle bsFDiagonal). I call following code on a toolbutton. Drawing works fine, but the polygon is not filled?

imgVect.MouseInteractVt := [miPutPolyLine];
imgVect.ObjBrushStyle[-1] := bsFDiagonal;
imgVect.ObjBrushColor[-1] := clRed;

Is there a way to fill a polygon?

Thanks.
alex

Hello Alex,
polyline must be closed to become filled polygon. So, you should set also:

imgVect.ObjPolylineClosed[-1] := true;

Thanks Fabrizio. That works.

Is there a way to suppress adding points to the polygonline, while keeping the mouse button pressed? I want only single clicks to add points to the polyline.

I'm sorry, no. At the moment, it cannot be disabled.
