[gentoo-user] qt5

[gentoo-user] qt5

[Michael Vetter]

Hello,

Recently I started developing on LXQT. As they are using Qt5 on their
developing version I added Qt overlay and unmasked Qt5.

I should add normally I am more the GTK applicatio user, running i3 as
window manager. So Qt and its configuration are kind of new to me.

Anyways, I got LXQT to run and started hacking. However I thought a IDE
would be nice. So I installed Qtcreator.

All applications so far (example: pcmanfm-qt using Qt5) are looking
good. But Qtcreator looks awful: grey font on white background and
whitefont on black background. I wondered why this was the case, and
after checking with ldd I realized that Qtcreator uses Qt4.

I tried to run qtconfig and choose a nice theme, as I was used to with
lxappearance for GTK.
However, no matter what I selected in "Select GUI style", the colors
stayed ugly. I tried Cleanlooks, Qtcurve and others. Then I saw that I
can manually change color palette. This is strange, on GTK themes come
with nice colors without selecting them by hand. Am I doing something wrong?

So I have several questions:
1. How to configure Qt4 themes/colors the right way?
2. Can I remove Qt4 totally and only use Qt5 for all applications?

I am aware that Qt5 is not stable, but the mask says its more or    less
table but masked for doing more tests.

Also I didn't see a USE flag for Qtcreator, no Qt4 no Qt5.

3. For testing I wanted to add gtkstyle USE flag to qtgui, then realized
that this doesn't exist anymore for Qt5. But Qtcreator seems to be
compiled for Qt4, so how to set gtkstyle for it?

4. Has Qt5 also the possibility to have gtkstyle?

I am thankful for all info I can get, also background information for
understanding everything totally, since this is the main goal of writing
this mail.

best regards,
Michael

BGO 525410 has some gentoo specific comments on lxqt-0.8.0 (qt5).

<snip>
I'm using slim as DM and openbox as WM right now.
I got no problems with the clock, panel, vt switching and also no segfaults
at configuring or such... Seems to be quite usable!
<end/snip>

File a gentoo bug, after you seek resolution at the lxde main site?
From what I've read, lxqt-0.8.0 is strictly qt5; some problems exist
if trying to support both qt4 and qt5. But you need to check
with folks running the latest codes for lxqt.  [1]

Last, I do not remember what is holding up the current masking of
lxqt-0.8.0 but it could be related to your problem?


good hunting!
James

From BGO-525410, the last entry:
" Jauhien Piatlicki gentoo-dev 2014-11-08 17:58:49 UTC
Moved to the tree. Will stay masked until Qt5 unmasking. In case of any
problems, please, create separated bugs blocking this one. "

Jauhien knows what he is doing. If he is waiting on the QT5 bug to
be resolved, then that is where it is sitting. Surely you should open
up a bgo ticket on QTcreator?

I am not sure there is any bug.
I thought it's only about configuration. My main reason for writing the
initial mail was to get better understanding on what is going on.

Actually I still haven't gotten that :-/

Anybody could tell me what's going on and answer my initial questions?
