RTTI problem with PaintBox

rbuser

Hi again,
I tried to export the OnDrawPaintBox event through Rap and now I get an
error when I compile the Rap code. "TCanvas is not type identifier"

My question is, if I have to create Rap extensions for the TCanvas, do
I have to create extensions for its object properties (Font, Brush,
Pen...)?

Or is something already been done to export the TCanvas in RAP?

Yes, you need to surface the class TCanvas and the properties you want to
use in RAP. The RAP tutorials show how to surface the TDatabase class.
Essentially, you'll need to take the same approach and create
TmyTCanvasRTTI = class (TraTComponentRTTI)

This also means that every property you want to surface has to have RAP RTTI
built for it. Most of the properties in TCanvas also rely on enumerated
types, which need to be supported. From the surface, it may not appear to
be much, but it will require significant work to get it working correctly.
