Hi Joe,
Following is a drawing view subclass, that should be transparent:
public class NMyDrawingView : NDrawingView
{
public NMyDrawingView()
{
//Set the default backcolor
SetStyle(ControlStyles.SupportsTransparentBackColor, true);
this.BackColor = Color.Transparent;
}
public override void DoPaint(PaintEventArgs e)
{
if (Document == null)
{
if (DesignMode)
{
PaintEmptyInDesignMode(e);
}
return;
}
if (LockRefresh)
return;
GraphicsState state;
NPaintContext context;
try
{
//e.Graphics.Clear(WindowBackColor);
if (NeedsWindowBackgroundPaint(e))
{
state = e.Graphics.Save();
context = ProvideViewPaintContext(e, PaintPass.Background);
PaintWindowBackground(context);
e.Graphics.Restore(state);
}
if (NeedsDocumentBackgroundPaint(e))
{
state = e.Graphics.Save();
context = ProvideDocumentPaintContext(e, PaintPass.Background);
PaintDocumentBackground(context);
e.Graphics.Restore(state);
}
if (NeedsViewBackgroundPaint(e))
{
state = e.Graphics.Save();
context = ProvideViewPaintContext(e, PaintPass.Background);
PaintViewBackground(context);
e.Graphics.Restore(state);
}
if (NeedsDocumentForegroundPaint(e))
{
state = e.Graphics.Save();
context = ProvideDocumentPaintContext(e, PaintPass.Foreground);
PaintDocumentForeground(context);
e.Graphics.Restore(state);
}
if (NeedsViewForegroundPaint(e))
{
state = e.Graphics.Save();
context = ProvideViewPaintContext(e, PaintPass.Foreground);
PaintViewForeground(context);
e.Graphics.Restore(state);
}
}
catch (Exception ex)
{
Trace.WriteLine("Drawing view paint failed. Exception info follows: ");
Trace.WriteLine("------------------------------------");
Trace.WriteLine(" Message: " + ex.Message);
Trace.WriteLine(" Stack Trace: " + ex.StackTrace);
Trace.WriteLine("------------------------------------");
}
if (SmartPaintService != null)
{
SmartPaintService.Reset();
}
}
}
The DoPaint method does exactly what the default implementation is doing, but the commented line:
//e.Graphics.Clear(WindowBackColor);
which actually makes the background entirely black, with the WindowBackColor is set to transparent.
