nomacs Image Lounge windows not linked to pinned launcher

[MarcRdC]

I have a pinned launcher for nomacs Image Lounge application but related windows are not linked to that launcher in the dock. Sometimes, a new — and incorrect — icon is created; on other occasions, some of the windows are erroneously grouped with GIMP.

File <org.nomacs.ImageLounge.desktop>

``` [Desktop Entry] Name=nomacs GenericName=Image Viewer Comment=nomacs is a free, open source image viewer Exec=nomacs %F Terminal=false Icon=org.nomacs.ImageLounge Type=Application Categories=Graphics;RasterGraphics;Viewer;2DGraphics; MimeType=image/gif;image/jpeg;image/png;image/bmp;image/tiff;image/x-eps;image/x-ico;image/x-portable-bitmap;image/x-portable-graymap;image/x-portable-pixmap;image/x-xbitmap;image/x-xpixmap; ```

File <gimp.desktop>

``` [Desktop Entry] Version=1.0 Type=Application Name=GNU Image Manipulation Program GenericName=Image Editor Comment=Create images and edit photographs Keywords=GIMP;graphic;design;illustration;painting; Exec=gimp-2.10 %U TryExec=gimp-2.10 Icon=gimp Terminal=false Categories=Graphics;2DGraphics;RasterGraphics;GTK; StartupNotify=true MimeType=image/bmp;image/g3fax;image/gif;image/x-fits;image/x-pcx;image/x-portable-anymap;image/x-portable-bitmap;image/x-portable-graymap;image/x-portable-pixmap;image/x-psd;image/x-sgi;image/x-tga;image/x-xbitmap;image/x-xwindowdump;image/x-xcf;image/x-compressed-xcf;image/x-gimp-gbr;image/x-gimp-pat;image/x-gimp-gih;image/tiff;image/jpeg;image/x-psp;application/postscript;image/png;image/x-icon;image/x-xpixmap;image/x-exr;image/webp;image/x-webp;image/heif;image/heic;image/svg+xml;application/pdf;image/x-wmf;image/jp2;image/x-xcursor; ```

A quick workaround should be to add StartupWMClass=Image Lounge to your .desktop file.

Thank you for the workaround!
