I'm trying to draw simple lines and paths on a jDrawingView, but the
property PaintStrokeWidth seems to have no effect.

For example:

    jDrawingView.PaintColor := colbrBlue;
    jDrawingView.PaintStyle := psStroke;
    jDrawingView.PaintStrokeWidth := 1; // I tried 0, 0.1, 0.5, 1, 2,
3, 10, etc. -- no difference!
    jDrawingView.DrawLine(10,10, 200, 10);  // draw a horizontal line

No matter what PaintStrokeWidth value I use, the result is always the
same: a single pixel line. Google calls it "hairline", which,
according to the documentation, corresponds to Width = 0. (See link
below for documentation)

Am I missing something?  Any help is most appreciated!

Here is the documentation page:

QuotejDrawingView.PaintStrokeWidth := 1; // I tried 0, 0.1, 0.5, 1, 2,
3, 10, etc. -- no difference!

Maybe some bug....

I will do some test....

Thank you!
