Not use system icon theme for app icon

[varlesh]

On Plasma 5 with widget task manager QMPlay2 use its icon (when player run):

But if player close - use system app icon theme:

I'm add option StartupWMClass="QMPlay2", "QMPlay2" on desktop file, but this not working :(

I don't know. I can try on Plasma 5 later (Arch Linux), but I don't know how does it work (I'm using Mate).
What is this? Is it an app launcher or system tray?

[varlesh]

This panel launcher "tasks widget (icon only)". Maybe this icon on binary or program not like SVG. You can test this with icon:
https://raw.githubusercontent.com/PapirusDevelopmentTeam/papirus-icon-theme-kde/0d2972a72e7bc02437475bb16fdf9be1154a5fac/papirus/48x48/apps/QMPlay2.svg

[zaps166]

Maybe just export it in Inkscape as PNG (e.g. 128x128) and replace the icon: /usr/share/icons/hicolor/128x128/apps/QMPlay2.png ?

[varlesh]

By the by this symlink /usr/share/icons/hicolor/128x128/apps/QMPlay2.png > ../../../QMPlay2.png

[zaps166]

sudo rm /usr/share/icons/hicolor/128x128/apps/QMPlay2.png
sudo rm /usr/share/icons/QMPlay2.png

And then just paste your new PNG icon here (/usr/share/icons/hicolor/128x128/apps) or maybe SVG will also work.

Which distribution do you use? If Arch Linux you can currently switch to qmplay2-git - it doesn't create the symlink :)

[varlesh]

This not working (also i clear cache icon and plasma):

i'm use stable version on Manjaro KDE

[varlesh]

Ok, i'm compile git-version from AUR and check this

[zaps166]

I don't know if deleting cache doesn't help... Did you restart plasma? This is QMPlay2 independent...

[varlesh]

Yes i'm delete cache and restart plasma:

rm -rf ~/.cache/plasm*
killall plasmashell

[varlesh]

It's strange hm...
Git-version:

[varlesh]

use xorg icon

[zaps166]

Check whether /usr/share/icons/QMPlay2.png does not exists.
Check whether /usr/share/icons/hicolor/128x128/apps/QMPlay2.png exists.

and check the icon name in *.desktop files.

Delete caches, restart plasma...

[varlesh]

Player closed - use system icon

[zaps166]

Maybe there is another problem - does plasma update the icon from application icon?

[varlesh]

/usr/share/icons/QMPlay2.png does not exists - confirm this
/usr/share/icons/hicolor/128x128/apps/QMPlay2.png exists - confirm this.
Desktop:

[Desktop Entry]
Exec=QMPlay2 %F
Icon=QMPlay2
Name=QMPlay2
StartupNotify=false
Type=Application
Categories=Qt;AudioVideo;Player;Audio;Video;
MimeType=video/mp4;video/mpeg;video/ogg;video/quicktime;video/x-msvideo;video/x-flv;application/x-shockwave-flash;application/vnd.rn-realmedia;video/vnd.rn-realvideo;video/3gpp;video/3gpp2;video/dv;video/webm;video/x-matroska;application/x-matroska;video/x-ms-asf;video/x-ms-wmv;video/x-ogm+ogg;video/x-theora+ogg;video/mp2t;audio/x-ape;audio/mp4;audio/AMR;audio/aac;audio/webm;audio/x-matroska;audio/ac3;audio/flac;audio/mp2;audio/ogg;audio/x-flac+ogg;audio/x-aiff;audio/x-wav;audio/x-vorbis+ogg;audio/x-tta;audio/x-wavpack;audio/x-musepack;audio/x-ms-wma;audio/x-ms-asx;audio/x-mod;audio/x-s3m;audio/x-stm;audio/x-xi;audio/x-xm;audio/x-it;audio/mpeg;audio/x-mpegurl;audio/x-scpls;audio/prs.sid;audio/x-j2b;audio/x-sfx;audio/x-umx;audio/x-gme;video/x-bink;

Now del cache and restart PC and check

[zaps166]

I think that Plasma5 just loads the application/window icon instead of system icon if QMPlay2 is open.

[zaps166]

I think that this line:

QMPlay2/src/gui/Main.cpp

Line 570 in 42c5d1c

QApplication::setWindowIcon(QMPlay2Core.getQMPlay2Pixmap());

causes the problem. If yo really want to use other icon then I can try to load the system icon in this place.

[varlesh]

For example, my friend programmer and use this variant:
Maybe help this :)

setWindowIcon(QIcon::fromTheme("krudio",QIcon(path+"krudio.svg")));//иконка окна
    if(save){//сохраняем изменения в базу
        QString str;
        QSqlQuery a_query;
        bool b;
        //Вставить значения
        QString str_insert = "UPDATE "+tableSettingName+" SET value = %1 WHERE setting ='%2';";
        str = str_insert.arg(colorNumb).arg("color");
        b = a_query.exec(str);
        if (!b) {qDebug() << "Данные не сохнаняются";}
    }
}

restart pc and clear cache not solved problem

[varlesh]

Use system icon (if available) or not available use fallback icon from hicolor or another method.

[zaps166]

Ok, I'll try :)

[zaps166]

Please recompile & test :)

[varlesh]

ok

[varlesh]

Not working - use xorg icon :(

[varlesh]

[zaps166]

Hmm, ok, switching to Plasma 5 (please wait)...

[varlesh]

Ok. I'm clear all cache and icons too, restart plasma, convert png to svg and copy to system icons folder... but always show xorg icon

[zaps166]

No problems (tried with CMake icon 😃)... Try to remove rm ~/.cache/icon-cache.kcache or maybe all files from cache directory and then restart Plasma.

[varlesh]

delete all ~/.cache but not solved. convert svg to png (VLC icon), restart plasma. Please see on /usr/share/applications and hicolor vlc icon, but on launcher xorg

[zaps166]

And what if you close QMPlay2? Still Xorg icon?

[varlesh]

No, close - use system icon (VLC now)

[zaps166]

I can't reproduce. Everything is OK on my Plasma5 and on Mate.
What if you do: sudo ln -s /usr/share/icons/hicolor/128x128/apps/QMPlay2.png /usr/share/icons/QMPlay2.png? Maybe it still remembers the old icon location /usr/share/icons/QMPlay2.png and tries to load non-existing file at runtime? Maybe it has another cache somewhere else?

[varlesh]

I convert vlc.svg to vlc.png on gimp. Moved new QMPlay2.png to /usr/share/icons/breeze/apps/48/ and to /usr/share/icons/hicolor/128x128/apps/
On dolphin and KMenu show VLC icon, also if touch player icon on panel - show VLC icon too (player closed). Bur run player and show Xorg icon on panel

[varlesh]

[zaps166]

What icon do you have in tray (expand it, the indicator on the left of the temperature) if player is running?
What if you copy/move the QMPlay2.png to /usr/share/icons ?

[varlesh]

on systemtray use vlc icon

[zaps166]

The system tray icon is exactly the same icon as on taskbar (see f2facc5 - it uses the window icon). Something must be wrong with your KF5. Could you try on Xfce4, Mate or any other DE/WM? You can try to load openbox in Plasma5 yaourt -S openbox; openbox --replace and then try. Then go back to kwin kwin_x11 --replace from "Alt+F2" launcher. Maybe kwin5 has bug? If you are using Manjaro "stable" repo then you probably have old Qt 5.6.0. Qt 5.6.1 is much better than Qt 5.6.0 (less bugs).

[varlesh]

It's strange because other Qt5-apps show system icon, example qbittorrent.
Ok i try this latter... and go now sleep :)

[zaps166]

I think this is Kwin5 or Plasma5 bug (or something wrong with cache), because Qt loads tray icon from window icon and the tray icon is OK, but window icon is not OK on Plasma/Kwin (internally in Qt is OK).

[zaps166]

Ok, mee too 😃 2:20 AM in Poland

Later (if it still will work bad) please try with openbox WM on Plasma5 :)

[varlesh]

I'm check on openbox - use system icon on panel, it's OK. This bug Qt or Kwin. After upgrade Qt5 and Plasma check again. Thx for support :)

[zaps166]

So probably Kwin5 bug (or unknown other cache) :)
According to #30 (comment) probably it has problem because of changed icon directory (qmplay2 and qmplay2-git). Sorry, but I can't help, this is out of scope...
