Additional transparent Window when using QFileDialog::getOpenFileName
-
Hi Guys,
I have an issue which I can't solve by myself. It occurs when I try to use QFileDialog::getOpenFileName. Then I've get additional window in left corner fully transparent (Until you move it). There is an "Screenshoot":http://pl.tinypic.com/r/wl2lud/8 . Funny thing is that this very same windows also appears when I use "Open File or Project" option from menu file in QTCreator itself. It's very annoying. I've tried reinstall qt creator and recompile Libs as well - and nothing helps.
Any ideas?
Thanks

Hi and welcome to devnet,
What version of Qt are you using on what version of Ubuntu ?
-
Ubuntu 12.04.
I have Compiled QT 5 and QT 4 libs as well. This project however use QT version 4.
Qt Creator 2.8.1
-
Can you try again but with Ubuntu's provided Qt 4 ?
-
I can't reinstall whole system.
-
I didn't ask for that. It's just a matter of calling apt-get install qt4-dev or something like that.
-
I already tried that;)
-
So both Ubuntu's own Qt and the one you compiled yourself gives you this strange window ? Qt 5 also ?
-
Yep I've install QT Creator with QT 4, and then compile QT5 Libs. I've notice this strange windows recently, so I've recompile QT 4 and QT 5 Libs e.g. i've followed this steps http://qt-project.org/wiki/Building_Qt_5_from_Git but it won't work.

If you have built Qt 5.2 or greater, it won't work with Qt Creator 2.8.1 you need at least Qt Create 3
-
Qt Creator 2.8.1
Based on Qt 5.0.2 (GCC 4.6.3, 64 bit)Built on Sep 16 2013 at 12:03:05
-
With 2.8.1 you can't run code from 5.2 or greater. Since you have built from Git you should have something like 5.3
-
So, since I can't install QT Creator 3 on linux, all I must to do is completely remove all my QT file (Creator and Libs), and install it from scratch??
-
No need to go that extreme, you can also just build Qt Creator by hand, it's able to handle several Qt versions at the same time
-
But now, with this line (greaterThan(QT_MAJOR_VERSION, 4): QT += widgets) in my .pro file, shouldn't that solve my problem?

Hi,
Are you in a virtual machine? VirtualBox is known to cause graphics issues with Qt and OpenGL. (I'm not sure if this is related to your issue though, since you are using widgets)

No, I'm using ubuntu every day, so I don't use virtual machine.
