I can't load the mainwindow.ui. Says too many characters. Is there a way I can upload the project as a whole?

jsulm

@leinad Upload your project to some file sharing service and post the link here

leinad

Here is a link to a small project. Thanks for your help!

Your file is not available anymore.

Let's try this link.

It's been a while. Can someone take a look at this and provide some assistance?

Thanks.

Old link expired so here is a new link to the project. Please help!

Why did you add that scroll area alone in its own QSplitter ?

leinad

I'm trying to adjust the scrollarea size, this way users can show all or partial number of combo-boxes. If they expand to full size the scrollbar in the scroll area will disappear and they can see all the comboxes.

SGaist

You should rather add it to your already existing splitter. You don't have the effect you want because you put a single widget in a single splitter.
