Here you can change the overall look & feel of the graphical user interface of Structorizer. The different designs that appear in the submenu are those that are installed on your computer. Simply select one of them. Structorizer remembers the chosen theme and will load it automatically the next time you start Structorizer.

Here are four L & F examples of some part of the Diagram menu (in order of appearance: "Metal", "Nimbus", "Motif", "Windows"):

(Note that the screenshots throughout the pages of this User Guide were taken with different Looks & Feels.)

Problem with "Windows" Look & Feel under Windows 11:

As stated in Issue #1133, there arose a Look & Feel defect with Windows 11: Whereas most Looks & Feels show the selection status of menu items with both an icon and toggle function (as e.g. all the menu items below "Type" in the screenshots above) via a checkbox to the left of the icon, Look & Feel "Windows" used to indicate the selected status of such items by embedding the icon in a light blue box (see fourth of the screenshots above). With Windows 11, however, this did no longer work: In Look & Feel "Windows" there was no visible toggle status on menu items of this kind anymore. No newer Java (Swing) version (nor Microsoft) has fixed that by now. So far our only workaround recommendation had been to use another Look & Feel. With Structorizer version 3.32-35, however, we chose to offer a built-in workaround mechanism. On Windows 11 installations only, the Look & Feel preferences now provide an additional option "Use Windows 11 L&F workaround":

If activated this option will somehow simulate the former "Windows" L&F functionality by exchanging the icons on menu item status change, such that an icon version with light-blue background indicates the selected status:

With the language preference menu, however, another indication approach was chosen (which is closer to the standard with a checkbox symbol):

This workaround option is only enabled while L&F "Windows" is chosen. It has no impact on other Looks & Feels and it can be switched off at any time (e.g. after the L&F itself should once have got fixed).

Further hints:

• If you ever happen to come to a situation where the given design makes Structorizer crash (i.e. prevents opening it), then open the file structorizer.ini, which is located in the subfolder .structorizer of your home directory, with a text editor that copes with UNIX newlines, seek the line starting with "laf=" and delete it. Then start Structorizer again.
• The "CDE/Motif" Look and Feel may have some unexpected side effect. So the usual Cut, Copy and Paste hot keys (Ctrl-X, Ctrl-C, Ctrl-V) won't work within the Element editors, but the UNIX-like equivalent actions like central mouse-button click in order to paste may not work, either. Usually, Shift-Del, Ctrl-Ins, Shift-Ins (also being very common in Windows) may work instead, though. Likewise the size of the controls on some dialogs may vary so much that e.g. the OK button might not be visible without manually enlarging the respective dialog.
• See GUI Scaling if — besides the Look & Feel — the size of your icons or GUI fonts does not please you or e.g. if you want to scale up Structorizer including menus, toolbars etc. for presentation purposes.
