QCAD3 Unbuntu Mate Cannot See Tooltips

Good Morning I hope this is in the right place. I hope it may help others

Using the above software under default Mate desktop settings is made difficult because the tooltips are in the wrong colours

The problem seems to be a bug reported under Ubuntu themes package (see https://bugs.launchpad.net/ubuntu/+source/ubuntu-themes/+bug/1332100)

The solution I have used is to configure the appearance of all Qt applications using qt-config (see https://www.youtube.com/watch?v=M2W_7YsUiGE). Credit to Andrew Mustun of QCAD

To access Qt under Mate desktop go System/Preferences/Look and Feel/Qt 4 Settings

Default settings found

  • GUI Style = GTK+
  • Tooltip Colour = White
  • Fonts= Medium Italic

Change settings to

  • GUI Style = Cleanlooks
  • Tooltip Colour = Black
  • Fonts= Regular

Version Affected

  • QCAD Version: (3.14.3)
  • MATE Desktop Environment 1.12.1
  • Ubuntu Release 16.04 LTS (Xenial Xerus) 32-bit
