Lack of qt4-qtconfig package in Ubuntu 20.04 Focal Fossa

  • 772

I use an application called Mame Set Rebuilder (you can easily find references on internet) that is built in Qt4 in a .app format.

When I had Ubuntu 19.10, I was able to set the fonts of the application using the package qt4-qtconfig. Setting the fonts with this package prevents the app from using some predefined and ugly fonts.

Now I have a fresh Ubuntu 20.04 installation and the package has been removed from repository (and if I try to install it from a deb package, it requires some incompatible dependencies). The configurator for QT5 apps qt5ct seems not to be able to apply its configuration to QT4 apps.

Is there a way to improve the fonts of QT4 apps in focal fossa? Please consider that the app fully works, it's only an aestetic matter.

  1. It's a conscious decision. The maintainer of the application should port it to qt5. You may want to ask them if there is an interest to do so.

  2. If you're fine installing from PPA's, here's one that provides Qt4 for Ubuntu 20.04 LTS.

    I have found a workaround. I created a VM with Ubuntu 19.10 and installed qt4-qtconfig package. What the qt4-qtconfig tool do is to append some lines to the ~/.config/Trolltech.conf file. According to my settings, the content is the following:

    [Qt]
font="Ubuntu,11,-1,5,50,0,0,0,0,0"
Palette\active=#3d3d3d, #f5f6f7, #ffffff, #cbc7c4, #cccdce, #b8b5b2, #5d5d5d, #ffffff, #3d3d3d, #ffffff, #f5f6f7, #bdbdbe, #e95420, #ffffff, #0000ff, #ff00ff, #ffffff, #000000, #ffffdc, #ffffff
Palette\inactive=#3d3d3d, #f5f6f7, #ffffff, #cbc7c4, #cccdce, #b8b5b2, #5d5d5d, #ffffff, #3d3d3d, #ffffff, #f5f6f7, #bdbdbe, #e95420, #ffffff, #0000ff, #ff00ff, #ffffff, #000000, #ffffdc, #ffffff
Palette\disabled=#99999a, #f5f6f7, #ffffff, #cbc7c4, #cccdce, #b8b5b2, #99999a, #ffffff, #99999a, #ffffff, #f5f6f7, #bdbdbe, #e9e9e9, #ffffff, #0000ff, #ff00ff, #ffffff, #000000, #ffffdc, #ffffff
fontPath=@Invalid()
embedFonts=true
style=GTK+
doubleClickInterval=400
cursorFlashTime=1000
wheelScrollLines=3
resolveSymlinks=false
globalStrut\width=0
globalStrut\height=0
useRtlExtensions=false
XIMInputStyle=On The Spot
DefaultInputMethod=xim
audiosink=Auto
videomode=Auto
GUIEffects=none

    In this way, QT4 applications have a nicer appearance.
