How do I paint the treeview node +/- buttons outside a treeview?
Question
Similar to the ButtonRenderer
class, I want to be able to paint the +/- buttons used in TreeViewNodes
completely separately to any instance of a TreeView
. There doesn't seem to be a ControlPaint
method that does it, and drawing a Button doesn't look right. Where can I get the drawing code for a treeview node from?
Solution
You can draw most parts of the standard Windows controls using the Windows visual styles API.
I haven't tried rendering a tree view control, but take a look at the .NET VisualStyleRenderer
class, which appears to wrap all of the functionality of the unmanaged API.
