Re: [sc-users] drawing outside a UserView broken?

[thelych@xxxxxxxxx]

hi wouter,

with relativeOrigin = true the UserView draws in a separate, and  
constrained layer whose bounds are equal to the view bounds.
you cannot draw outside of it. It's like it clips the region.

there is no workaround.

I do not consider it as a bug. Actually i think drawing inside a view  
should be constrained to its bounds.

since relativeOrigin will be / is deprecated, a *possible workaround*  
would be to add a flag to disable this layer and allow to draw outside  
of the view
but this possibility will be a kind of *hack* : meaning there is few  
cases where those extended drawings won't be refreshed correctly,  
probably leaving the window with dirty drawings inside.

that should be probably discussed in the dev-list before.

until then you have to use relativeOrigin = false to draw your custom  
focus ring... wich i know may not stand in future releases.

best,
charles
