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!

https://rapidshare.nu/Tb2ds8iboe/test_zip

[SGaist]

Your file is not available anymore.

[leinad]

Let's try this link.

[leinad]

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

Thanks.

[leinad]

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.
