TBrowser font size

ROOT
1

Hi,

is it possible to change the font size in the TBrowser?
On high resolution displays, which become more and more common, it is very difficult to read anything.

Thanks!

You can create a .rootrc file and specify the font size for the GUI in there. If you open a ROOT session, gEnv->Print() will show you all active environment variables. You can then just create a file with variables as you like to overwrite whatever you like.

For example, you are probably interested in these settings (taken from my environment):

Gui.DefaultFont: -*-helvetica-medium-r-*-*-12-*-*-*-*-*-iso8859-1 Gui.MenuFont: -*-helvetica-medium-r-*-*-12-*-*-*-*-*-iso8859-1 Gui.MenuHiFont: -*-helvetica-bold-r-*-*-12-*-*-*-*-*-iso8859-1 Gui.DocFixedFont: -*-courier-medium-r-*-*-12-*-*-*-*-*-iso8859-1 Gui.DocPropFont: -*-helvetica-medium-r-*-*-12-*-*-*-*-*-iso8859-1 Gui.IconFont: -*-helvetica-medium-r-*-*-10-*-*-*-*-*-iso8859-1 Gui.StatusFont: -*-helvetica-medium-r-*-*-10-*-*-*-*-*-iso8859-1

The numbers in between all of the asterisks are the respective font sizes. ROOT looks for .rootrc files in ~/.rootrc and in the current working directory

Hi,

thanks a lot, this solved my problem, and the hint with gEnv->Print() will certainly become handy again later!

I still wish there was a simple gui option in the TBrowser window to change a basic setting like font size (or scale) on the fly, as I use my laptop in different settings, and not all external screens have high dpi. But that’s a minor issue, and for now, I’m just happy I can read things again :slight_smile:

Cheers,
