How to make container scrollable? #37

Closed matthiaswh closed 5 years ago

matthiaswh commented 5 years ago

Is it possible to make a container scrollable, independent of the window? Everything seems to be setup for this to work, but I can't find a way to make it happen. I have tried setting fYScrollEnabled on the container, and even setting the fScrollableHeights, but to no avail.

Like so

====================================
=----------------------------------=
=- stationary text box            -=
=----------------------------------=
=----------------------------------=
=- scrollable                   | -=
=- list                         | -=
=- of                           | -=
=- labels                       | -=
=----------------------------------=
====================================

Should work, but doesn't work. I have to check why.

It works under Windows, see https://github.com/trustable-code/NiGui/blob/master/examples/example_14_container_scrolling.nim. Under Gtk it does not work, it expands the inner container and the outer container gets the scrollbar. This needs to be fixed in the Gtk related part.

With the latest commit it should work under Gtk too. Does it work for you?

Works great! I made one small fix that was causing the horizontal scrollbar to show unnecessarily until the window was resized. I don't yet fully understand how all the Gtk code is working but I think this was the correct approach.

Great project btw!
