These features are additional extras to the plugin, not related to the themes nor Material Design but simply nice addons for the IDE.
This feature is adding decorations to the Project View to mimic the original Material Sublime Theme decorations.
Open and closed directories
When this option is on, files that are opened in the editor and that are edited will have their containing directories have a hollow directory icon (or outline directory) instead of the original icon.
Note: This feature requires Material Icons feature to work.
Note 2: If the Folder decorators option is set, the icon will match the decorator, but outlined.
Open Colored Directories
When this feature is on, the directories that have files open in the editor will be colored with the accent color
Theme in Status Bar
This setting adds a “widget” to the status bar to indicate which theme you are currently on. You can also click on it to open the Material Theme Settings.
Since version 2.9.4/2.10.4 you can also see your current accent color.
Themed Title Bar
This setting also allows the theming of the application title bar in Windows 10. To do so, it is actually setting the Windows Accent Color set by Windows.
Note: Since this modifies the color OS-wide, the color set by the plugin will stick even if you close the IDE/uninstall the plugin. Just follow the instructions at https://www.howtogeek.com/225893/how-to-personalize-windows-10s-appearance/ to set it to another color of your choice.
Mac OS with JRE 8
From version 2.5.0 the option came back with support for Mac OS. And unlike in Windows, this does not change the Registry but actually applies the background color to the IDE title bar only!
However it comes with a small price: by activating this option you are consenting to nullify the Dark Window Headers
feature from the
Appearance panel introduced since 2018.2.
Mac OS with JRE 11
Since 2019.1 all IDEs are now bundled with JRE 11 by default. However the developers at JetBrains removed the ability to set the transparent title bar, instead they completely removed it! However instead of mourning the disparition of the title bar and removing the feature altogether, we found out a solution by implementing a custom title bar and by delegating the events to the real, hidden title bar.
Now the title bar looks more embedded than ever! However, it is still in its experimental state, so it can still contain bugs. For instance, sometimes the titlebar would not show for some dialogs, the text could be out of sync with what is supposed to show, font rendering issues etc.
We are still working on improving this feature by the time, until perhaps JetBrains finally decides to implement it.
Note: This is only for IDEs with JRE 11 enabled, with the JRE bundled by JetBrains. Custom JREs will however display two titlebars, the real and the fake one together.
Note 2: This custom title bar is in experimental state, so bugs may happen. If you find a bug, please open an issue at https://github.com/ChrisRM/material-theme-jetbrains/issues if it’s not something that has already been discussed. In the meanwhile, if you cannot live with these bugs, you can still switch to JRE 8 or disable the Themed Title Bar option and restart the IDE.
This feature is currently not available in Linux. Since I’m not a Linux user, I have no clue how to accomplish that. Besides there are many distributions/frameworks of Linux, being Ubuntu, Gentoo, KDE, Gnome etc…
If someone is interested on a way to do so, please send me a PM by email or Slack, that would be awesome!
Q: I’ve disabled the plugin but I still get the themed title bar!
A: This happens because this is not a feature implemented by the plugin, but instead makes use of a feature of the operating system. Therefore even when the IDE is closed the setting will persist. You can change the color of the title bar in Windows by following the instructions at https://www.howtogeek.com/225893/how-to-personalize-windows-10s-appearance/
Q: I’ve got two title bars! / My title bar is gone! / My title bar is …
A: This is due to the Experimental Themed Title Bar implemented since 4.3.0. This feature is still in its experimental state so there could still be bugs. Please open an issue in the GitHub repository, and if it bothers you, you can either revert to the JRE 8, or disable the feature and restart the IDE to get back the real title bar.
Q: Somehow I’ve updated the plugin and now my window is empty!!!!!
A: This is a rare and weird case due to the custom title bar implementation. Reports have indicated that this issue happens only once and is fixed by… resizing the window! Theoretically it should be enough to fix the issue but if it’s not the case, please disable the Themed Title Bar until a fix is found.
