[Qt-creator] Embedded GUI Designer

[Petric Frank]

Hello,

is there a possibility to change the default font size of all GUI elements 
(i.e. combo boxes, line edits, group frames, ...) to an other value ?

Not only when the GUI have already been designed - also the ones newly 
created.

In short:
- GUI already designed - change font size of all elements
- new widgets - create them with an other font size by default

Currently the widgets are always created with a font size of 9.

kind regards
  Petric
