Re: [Interest] KDE's qqc2-desktop-style

[Jason H]

So I wrote the maintainer. He was amenable to it becoming a standard but 
cautioned that it's not the panacea that it seems to be - at least in its 
current form. However he thinks that if it were to become part of Qt the issues 
could be addressed by the Qt project.  He also stated that it had been 
discussed here and it was determined that there were "other plans" within Qt. 
But it seems that those never materialized? So maybe this should be 
reconsidered?

The severe limitation is that because of QStyle, it need to be linked with 
Widgets, which in turn requires QApplication instead of QGuiApplication. 
However I don't know why QStyle can't be copied into QtQuick for this one 
purpose. It only inherits QObject...

The line QT_QUICK_CONTROLS_STYLE=org.kde.desktop is only needed to it's not any 
of the other styles so that this style gets used. Sine it uses QStyle, which is 
already aware of platform styles, it should "just" work on all platforms where 
QStyle is supported! Yee-haw!

Only if you give reasons for it to be in qt-project rather than in KDE 
(assuming the maintainer accepts).


Is it due to lack of binaries for platform X, hard to build KDE software 
or ?


As I see it, it's because nobody knows about it, and as a result, Qt 
Quick results in your application not looking like a native one. (Which 
is my reason for sticking to Widgets and avoiding QML UIs.)




Many of the reasons people usually give should be tackled directly by KDE.
The software is great and already works in "non-KDE programs", so I 
assume it's some minor process that needs improving so people use it more.


If it's not in Qt, people just don't know it's there. Windows or macOS 
developers who use Qt don't have any reason to know what "KDE" even is.


IMO, Qt should make Qt Quick look native without requiring 3rd-party 
libraries for it.


Now that I know this exists, this is no longer an issue for me, I guess. 
But if I didn't read this mailing list, I'd never have known this even 
exists. I now might actually use QML for UIs (depending on how well this 
thing works; haven't tried it yet.)

No, it works pretty much everywhere and has no kde dependencies in the 
plug-in code : https://github.com/KDE/qqc2-desktop-style/tree/master/plugin


That does sound like a good solution for Qt Quick desktop apps! I wasn't 
sure what this meant:


  QQuickStyle::setStyle("org.kde.desktop");

The "org.kde.desktop" part made it look like this is tied to KDE.

This is just for KDE though, right? Interestingly, KDE is the only 
platform where my Qt applications don't look native, unless they compile 
it themselves (which they can't do in closed source applications; and 
most people don't compile applications themselves anyway.)
