This plugin is still in development. It mainly has cosmetic bugs (like the focus ring not always being drawn) and 68K bugs. So I wouldn't recommend using this plugin with real applications. Feel free to modify/improve/learn from the source as you like however.
This control replicates a canvas control pretty much, with some extras to help in developing custom controls.
1 - KeyDown event. When the control has the focus, it receives keydown events just like an editfield.
2 - Frame. It also draws an optional editfield frame around the control.
3 - ScrollBars. There are optional built-in vertical and horizontal scrollbars. Unfortunately they are non-live scrollbars (the drag manager takes over while scrolling), the control only receives ScrollChanged events after the scrolling is finished (when the mouse is released).
There is a simple demo project. I will include better demos later.
