Invoke draw(view) method on tool startup

[tomasz]

Hi,
Is there a way to invoke the draw(view) method of a tool immediately on a tool startup?
When I start my tool I want to draw some lines on the screen. Although the tool initializes correctly, the draw method is not started. I need to zoom in\out or minimize\maximize SU window to get the draw method fire up.

What am I doing wrong or what I am not doing which I should?

It's and annoying limitation that activate doesn't have a view argument.

What I end up doing is:

def activate
  Sketchup.active_model.active_view.invalidate
end

Some times, I've left it out, as my mouse move event continuously require the viewport to redraw.

As Thomthom said - at the start of the activate code invalidate the view - that's the same as zooming ?

Changing the viewport cause it to invalidate and trigger the draw events.

Thanks. It has done the trick.
I've been trying

def activate
     draw(Sketchup.active_model.active_view)
end

, but it has not worked.
