How to change Qt Creator fonts which look very small

AlexNevskiy

Hello qt guys!
I use Qt Creator 12 on OS Windows on laptop with FullHD resolution so it makes the font very small and I want to know how to change the menu and tool panes and panels font?
For the moment I have the look like this :

what is absolutely unreadable for me.

(The menu font I was able to change with system configs...)

The option DPI rounding policy has no any effect.

The simplest stylesheet like that

QMenu,
QMenuBar::item ,
QMenuBar,
QTreeView,
QListView,
QLineEdit, 
QPushButton,
QToolButton,
QComboBox,
QLabel,
QGroupBox,
QCheckBox,
QSpinBox,
QDoubleSpinBox,
QCommandLinkButton,
QAbstractItemView,
QHeaderView
{
    font-size: 13pt;
}

breaks the codes font size from time to time

Any suggestions?

Hi Alex,
without having tested it on Windows, this is what works for me on Linux.

Enable Hi DPI scaling here:

Set environment variable
QT_AUTO_SCREEN_SCALE_FACTOR=1
(you can replace the value 1 with whatever suits you)

@Axel-Spoerl Thank you for the answer. No one of your solutions couldn't help me by the way.

1 In new Creator there is substitution for Enable high DPI scaling mode option .

and no one of the items of this menu doesn't have an effect on pane or a menu but makes start screen and options dialog looks kind of ugly

I've tried QT_AUTO_SCREEN_SCALE_FACTOR and QT_SCALE_FACTOR different values but I don't know why they have no effect too. In much more older versions I worked with this enviroment variables, it had a small drawback by the way - the running app from Qt Creator had the same scaling option and texts looked large than it should be.

Have found somewhat a solution, changed text size from the Windows -> Settings -> Ease of Access -> Display -> Make Text bigger

And now it looks more readable

Of course it can take some unpleasant effect on other programs...

@Axel-Spoerl Ok

It looks to me, as if your solution is the only one.
Creator 12 reacts to high DPI scaling automatically.
My screen has 3840x2160 and I have blown up my scaling to 125%.
That works just nice in Creator, as well as in all other apps.
How that can be achieved in Windows - I don't know.

@Axel-Spoerl Yes, It looks that way.
Well, thanks for the help.
