#5: Fonts in the Karabo GUI
===========================

Fonts in the Karabo GUI
***********************

The karabo graphical user interface (GUI) offers a wide potential of **font**
settings. Every operator is free to configure his *scene* panels with the desired fonts.

However, not every operating system has every `font` available. Hence, configuring
a label with the *print font* ``Ubuntu`` will affect ``Windows`` operators, as the
operating system will find a substitute. This might not always match the size of the
labels in which the text is written. The only cure would be to make the label size larger.

   Font configuration of the label widget.


Print fonts that have the capability to render similar on MacOS, Windows and Ubuntu
are ``Sans Serif``, ``Arial`` and ``Helvetica``.

Therefore, from Karabo 2.7.0 onwards, the default font provided is **Sans Serif**, being the only candidate
that was available on all of our OS test machines.

**All previous font settings in the karabo projects remain untouched!**

.. NOTE::

    The karabo GUI (2.7.0) default `print font` is ``Sans Serif`` with a point
    size of 10 (before 11) and the minimum widget height is reduced to 18 pixels (before 20).
