Line indicators - SyntaxEditor for Windows Forms Forum

Posted 20 years ago by tobias weltner

Could someone provide a sample on how to create a new line indicator with an icon in the margin bar, in vb.net?
I managed to use the predefined indicators and understand that I basically have to inherit from them. But what I do not know is how to draw an icon or even set the background color.
Thanks!

This post (read our reply) has some info for doing the background color in VB.NET:

The drawing of the icon is done by doing this:

Protected Overrides Sub DrawGlyph(ByVal g As System.Drawing.Graphics, ByVal bounds As System.Drawing.Rectangle) 
    'Paint here
End Sub

Thanks!
I was hoping to get pointed to a code snippet that actually uses DrawGlyph to draw an icon out of an image list for example. I am new to .net and not really proficient when it comes to drawing something, but from what I learned so far it must be quite easy...

I'll dig into it... ;-)

You just need to look into the Graphics object. That has methods like DrawImage that you would use to draw an Image from an ImageList.
