When opening a file the directory select box does not allow to choose a directoy. Also behind it are several buttons, all but one only showing when mose is moved over them. They do not have any text and don't do anything. The buttons "Documents" and "Examples" behind the above mentioned buttons work as expected. Reproducible: Always Steps to Reproduce: 1. Open Lyx 2. Choose File/Open or click respective button 3. Try to change directory using the directory select box Actual Results: Items in directory select box are grayed out. Choosing one does not have any effect. Expected Results: Items in directory select box are black. Choosing one displays content of directory in main area of dialog box.

can not reproduce it here (x86,qt-4.3.0)
Created attachment 132889 [details] Screenshot of file open dialog This is a Screenshot of the file open dialog with the mentioned problems. I know it doesn't help with reproduction, but maybe clarifies the problem. If you need more information about my setup please let me know which information and how I can obtain it. Thank you for your work!
i propose you come with this on lyx list. maybe somebody another meet this problem too.

See Message on LyX-Bug: This one seems to be a Qt4 bug on gentoo. Jochen, please try compiling the attached test program and report back whether you see the same problem. I tried it: Yes, I see the same problem. Also I see the repeated message QPixmap::scaleWidth: Pixmap is a null pixmap on sdtdout. Reassing to Qt4?

what is your version of qt4 ?

mine was 4.3.0.
4.3.1-r1 is also ok for me.
Now I have the icons. The only difference I can imagine, is that I set the global use flag "png" and did an emerge --newuse --update world and it compiled four packages, don't know exactly which. Maybe the icons are in PNG format? Don't know if anything can be done in the ebuilds to make sure that flag is set or something similar.
if there is no receipt how to repeat and it works for you, what about to close the bug now?

have you tried it? anyway, this has nothing to do with lyx and tex herd is of no help here.

I have never seen such a problem, perhaps you would know what's causing it. If the test program fails then it's probably not lyx's fault.

My assumption would be that the problem would occur if above use flags had "-png".
This will probably need to be rechecked with the split qt4 layout and which useflag causes it to be broken. Also, maybe it can be closed as invalid since it could be the normal behavior of QFileDialog: not working nicely if png support is disabled. I dont know qt enough for that.
libpng is a mandatory dependency in x11-libs/qt-gui. Use flag gone, problem, too. :) Bug can be closed, once Qt 4.4.1 went stable.
From a Qt point of view this bug is invalid. It is completely expected behaviour when compiling qt without png support. Therefore packages should add a QT4_BUILT_WITH_USE_CHECK="png" or use an eapi-2 style use dependency, when said behaviour is unwanted. Reassigning to tex herd for that reason.
