Last change on this file since f8e5161968 was c8ed26ddf1, checked in by Oleksii Serdiuk, 12 years ago

Implemented color selection from Settings Dialog.

Changing background color appeared to be much harder than expected, so
this feature was removed for now. It is possible to change background
color of the solution output area. However, this background change
doesn't affect printing and export - there background color always stays
white. Will investigate possible workarounds later...

Closes ticket:13 - All colors should be configurable through Settings Dialog
  • Property mode set to 100644
