Qt 4.8.2 on linux

[Destiser]

Hello all,

with the release of mint 14, I made a fresh install of the OS.

Now, I wanted to install the Qt SDK, but some shit happened probably and a lot of hassle was on the way. I managed to install the SDK but no Creator anywhere. So I looked here and figured out I needed to install it seperatly. Then I was sick of it, and just opened the software manager, and installed Qt SDK from there. Aha, Creator was there, version 2.5.2 (august 2012) with Qt 4.8.2 under the hood.

I opened an old project to test if everything worked, it was a 4.7.4 project but I managed to set it to use 4.8.2. Wonderfull, I ran the project and what does my eye see?

A WIN95 GUI!!!!! What have I done to deserve this horrible thing? Is this the way Qt is heading? Only Windows compatible GUI-styles? WTF, after all those troubles I find out Qt is making my apps look like shit.

Please just tell me that I have done something wrong and that it can be fixed. And yes, how to fix it is what I want to know.

Thanks!

LOL Yes, you have done something wrong but I have no idea what exactly. The "Win 95 GUI" thing means your program cannot find widget style plugins and uses a fallback that indeed looks like old Windows UI. I suggest you uninstall everything Qt related (unless Qt is required by your system, in this case leave the Qt runtime) and reinstall the SDK. Hopefully it will install properly this time. If not, try observing any details related to the failure, note them down and post here. Also try running the SDK maintainance tool and see whether anything obvious is missing from the installation.

ok then... what do you recommend that I install? The one from the software repository or direct download?

[wysota]

I'd go for direct download but it doesn't really matter that much.

[Destiser]

Ok, I re-installed everything via direct-download and I still have the same problem.

I scooped the internet and apparently it's qgtkstyle that can't detect my current GTK theme. Unfortunatly, I have found no answers. So my question is, on what does qgtkstyle depend on to find my current gtk theme? When I know that, I can take steps to solve the issue.

So, any qt dev who knows this?

[wysota]

What happens if you run a Qt application with a "-style plastique" parameter?

[Destiser]

All other styles work. But no GTK+ substyling.

[wysota]

Maybe it's just a matter of configuring something in your system.

[Destiser]

omg... apparently, when I built it first, I hadn't the dev files of gtk, installing these and recompile solved my problem. That's why noobs like me need an installer that takes care of these things.
