Theme problem

meho_r · 01-02-2011, 11:18 AM

Hi

I updated calibre yesterday to 0.7.36 and noticed that my theme is broken (looks like Win98). I tried changing couple of Gnome themes (with KDE settings to follow and use GTK+ style) to make sure it isn't a particular theme problem, no avail. I also tried setting KDE theme to native "Oxygen", didn't help. Using "qtconfig" I managed to apply two styles: "Clearlooks" and "Plastique", but KDE's "Oxygen" and GTK+ failed again. This didn't happen with 0.7.2x versions. Ideas?

I'm using Debian Squeeze, 64bit, Gnome DE, and "GTK+" Widget Style for KDE applications.

your theme's are probably incompatible with Qt 4.7 which calibre switched to recently.

meho_r · 01-02-2011, 03:26 PM

OK, thanks a lot for prompt reply. The installed version on my system is 4.6.3. 4.7 is still in experimental repos, so I don't think we'll see it soon on Debian testing.

Yeah, Qt theming is rather messy, I may have to start distributing theme plugins with the calibre binary. The problem with doing that is that then your system theme wont be used (even if it is compatible) and I'll get complaints from people about how calibre doesn't look like the other apps.

Indeed. From whatever side you look, seems like a double-edged sword

I'm having this same problem, however I am using qt 4.7.2. Is there something I missed?

Edit: I'm using kde 4.6 64bit on kubuntu natty btw

What version of calibre are you using?

Natty Isn't exactly 'stable'

Natty (Gnome) LIve CD won't even run the same 2 times in a row on my Dell D4600

(I've seen the new desktop twice, the rest of the time I have been lucky to get it to run enough to do anything useful, then, it was the old desktop that came up? Yes it was Natty.)

HalfEmptyHero · 03-31-2011, 11:58 PM

True, natty might not be stable but I don't think that would be the problem. All my other Qt apps look fine, that's gotta mean something right? But honestly, besides a few programs crashing once in a while, I haven't had any problems with natty.

As for calibre, I'm using version 0.7.52

It means that the style plugins in your OS are incompatible with the Qt libraries shipped with calibre. The only fix I know for that is to compile calibre from source on your OS.

Well I got tired of all the crashing on Natty, so downgraded to Maverick. The theme looks normal on it, so I'm happy.

I realize this is an old thread but it fits my situation.

what I'd like to find out is if you or anyone knows exactly what in qt 4.7+ breaks some gtk themes? I'd like to fix/update my theme if possible.

with calibre bin pkg up to r0.7.27 I get the gtk theme's scrollbar, button and other graphical effects (all the png elements in the theme); with r0.7.28+ I only get the theme's color treatments which from what I can tell is when calibre switched to qt 4.7.3.

I've done a lot of searching to see if there are tweaks I can make to the gtk theme but I'm not getting anywhere.

or I could build calibre from source as your subsequent post here mentions but given I'd only have qt and other calibre deps installed long enough to compile calibre I'd like to create a binary/standalone calibre (which the src INSTALL readme doesn't appear to go into) - did I misread in a calibre faq/doc that you said trying to do that would be very difficult? or did you just mean for a windows user it would be too difficult?

thanks.

calibre currently *requires* Qt 4.8 so compiling from source wont help you if you want to keep Qt before 4.7.3. There's no automated way to create standalone calibre binaries, the script I use to do it is specific to my build VM. But if you have the time, you can try adapting it, it is linux/freeze2.py and it is launched by

python setup.py linux_freeze
