Hello everybody,
I must admit that I'm a gtk noob (just started to use it yesterday)
but I couldn't figure it out by myself...
I try to achieve the following:
I want to display a smaller part of a bigger image in a window
alongside with some buttons. The image part should NOT have
scrollbars but be scrollable in a grab-n-drag like fashion (like with
the grab cursor in photoshop).
My initial solution was to load the image as a gtk_image and put it
into a gtk_viewport then catch any clicks on the viewport and adjust
its gtk_adjustments accordingly. That scrolling kind of worked BUT...
the viewport always resizes itself initially to be as big as the
whole image - blowing my app's layout and extending well beyond my
app's window.
It works as expected with a gtk_scrolled_window but that shows the
scrollbars I try to avoid. If I set the policy to show no scrollbars
the problem returns - a huuuge viewport out of control.
I tried to pack the viewport/scrolled_window together with the
buttons into hboxes or vboxes or tables... same result.
I am afraid I may not have understood the gtk layout system, yet... :-?
Thanks for your help!
Thorsten
