I have been wishing that a canvas was a container lately. Would it be
possible to use the canvas peer from the toolkit in a subclass of
container?? I want canvases in canvases in canvases (you can probably
guess why) to take advantage of the lovely features of containers.
I want something like this:
class ContainerCanvas extends panel??
{
public ContainerCanvas()
{} // Super has no contstructor
public CanvasPeer AddNotify()
{
...
}
}
In other words just override addnotify in panel so thatr I can have an
invisible (well canvasable, transparentable image) component. I tried
something like this with Container itself being the superclass and I got
shot down. It griped about there being no constructor for Container().
But of course there isn't a constructor, it is an abstract class, no?
Any plans for containers like this? I used panel cause its
generic...ASny further thoughts?
