Application Settings

There are some settings that not only apply to a specific widget or page, but to the WebUI application as a whole. These settings can be accessed through the Application Settings menu, which you can open by clicking on the applicationsettings-icon icon:


Use Classic Theme

From AIMMS 4.59 onwards, the look and feel of the WebUI has been upgraded to a more modern look and a consistent styling. However, for app developers who need more time to make sure their customized application looks as required with this new theme, the WebUI will offer you the choice which theme you want to use. More specifically, if you open an entirely new WebUI application, you automatically get the new look and feel (because there cannot be any backward compatibility issues in that scenario). If you open an already existing WebUI, however, you are offered the choice to try the new theme or to keep the old one for the time being. Should you want to toggle between the two, after having made this choice, we offer the ‘Use Classic Theme’ option in the ‘Miscellaneous’ tab. Simply set the switch to ‘on’ for the old theme, or to ‘off’ for the new theme:


Besides this, we offer a ClassicTheme.css file, which you can use to adjust some settings when you choose to retain the classic theme. The comments in this file should provide pointers on what to change. When adjusted, the file should be copied into the resources/css folder of your WebUI project. Furthermore, make sure you do use the new page navigation menu, as released with AIMMS 4.53.1.

When opting to use the new theme, we offer two .css files, which you can use to easily add a logo to the header bar of your WebUI pages and to change the color of the horizontal line below the header bar. The ReadMe file offers guidance on how to do this. If you indeed start using the new theme, we strongly advice you to ‘start from scratch’, in case you are using lots of customized css for your model. If you want a more extensive change, we suggest to connect with our support team. Please also make sure to remove any ‘ClassicTheme.css’ file, as described in the previous paragraph, in case you have copied it to your css folder.
