Customizing the Look & Feel

Overview

Some parts of the QluMan appearance may be customized: a) It’s possible to specifically adjust the look of a few individual GUI components and b) fonts, the so-called widget style, including color themes may be changed to modify the general appearance.

QluMan Preferences

In the Preferences dialog at File  Preferences, one is able to customize specific parts of the QluMan GUI Look & Feel. The tree on the left shows all the settings available for customization. Each QluMan component may have its specific settings, so the options available here depend on the components installed on a particular cluster.

The QluMan Preferences dialog

To change a setting, select the component to be customized, e.g. Slurm  Accounting  Colors. In this example, one can set the colors that are used to indicate Slurm accounts, users, the default account of users and the root user. To change a color, select the property in question and hit the Edit button. A color-picker dialog will then come up. Select the new color and click OK. Among others, one is also able to customize the column height of the Job Management and More Information tables here.

Customizing general Properties

Since the QluMan GUI is a QT application, it’s general Look & Feel can be controlled with the nice Qt5 Configuration Tool (qt5ct). It can be started by selecting the Manage Cluster  GUI Preferences menu entry. You’ll then have the options to modify appearance, fonts, icon themes etc.

Customizing Appearance

The Fusion widget style The Kvantum widget style The QtCurve widget style

The general appearance of the GUI is mainly influenced by the widget style and the color scheme. Both can be selected when the Appearance tab is active. 5 widget styles are available to choose from. For each of them one can select the Default color scheme, choose a pre-defined custom one or create and select a fully customized scheme.

If you choose the Kvantum widget style, you will have all options to select and create nice and customized themes. Please check this guide for details. The Kvantum GUI tools may be started from the QluMan container as follows:

0 user@workstation ~ $
singularity exec /usr/local/bin/qluman-qt kvantummanager
0 user@workstation ~ $
singularity exec /usr/local/bin/qluman-qt kvantumpreview

To change the font type and size, click on the Fonts tab. You can select your preferred general as well as fixed width font together with their size. Clicking the Apply button changes the corresponding font in the QluMan GUI on the fly.

Using the Icon Theme tab you can select a custom icon theme and under the Interface tab you’ll find a collection of miscellaneous settings to be customized.

Click Apply and OK when done with all of your customizations.
