Use PlasmaCore Units for Icon Sizing and Fix Tiles Text Overflow

Aditya Mehra requested to merge work/fix-scaling-using-plasma-units into master

  • Depending on Qt Scale Factors does seem to be causing layout issues when targeting different resolution screens, even two different environments, for example i.e a Monitor and a TV at the same resolution of 1920x1080 seem to have a mix bag of breakages using the Qt Scale Factors and it seems to get worse when the actual screen might be 4k resolution but being forced to work at a lower resolution like 1920x1080 for sbc hardware that cannot support 4k.

  • Current fix replaces all files using Kirigami.Units.iconSizes with PlasmaCore.Units.iconSizes to use the previous DPI scaling method originally designed around, seems less hacky than using Qt Scale Factors

  • Fixes tiles text overflow when Application Name and Descriptions are very long by limiting the Description to a single line when Application Names are taking maximum of the tile space

  • Allows sections in the launcher to be hidden when no applications belonging to the specific category are shipped or installed, adds additional key navigation logic for this.
