Restrict size of event window

["Stephan Arts" <stephan xfce org>]

Hi,

I am trying to solve bug #3823[0], but I am having a hard time
figuring out what I am doing wrong.

The problem is as followed:

The application (ristretto) has a thumbnail-bar (see on the right side
of the screenshot[1]). This is a container widget which allows
scrolling of it's children. Now, when a child is partially located
over the edge of the container, the widget is only drawn for the part
which is located on the container. There is one problem though, the
event-window is not restricted. When the image is scrolled beyond the
top of the container, that image will assume the events. Not the
zoom-buttons you see there.

I have the idea I am doing something fundamentally wrong, but I fail
to see what that is.

Could you help me?


Regards,

Stephan
