Is a CornerWidget for ScrollBars easily made possible?

[Metallicow]

QT has this nice little customizable widget built in scrollbars.(usually I
place a small 16px icon button there)

Strangely enough, I even wanted one of these before QT went and did it
actually.
I guess great minds think alike.

How easy would it be to hook into the existing widgets scrollbars and make
something like this possible with regular widgets with scrollbars?

Is wxWidgets ever planning on implementing something like this for the base
library widgets?

It might be possible with some widgets, but probably not all. The issue
is that for native widgets that have scrollbars wx has no way to control
or even get access to those scrollbars. Also that area would be
considered outside of the window's client area, and there is much in wx
that assumes that everything will be inside the client area.

There are no plans that I know of to expose functionality like this.
