Miscellaneous Swing Components

Messages provides a way to show simple message boxes, input dialogs (modal dialogs with a text field), and chooser dialogs (modal dialogs with a combo box). On macOS, the message boxes use the native UI.

The showCheckboxMessageDialog() function provides an easy way to implement a Do not show this again checkbox on messages.

tip

Avoid Modal Dialogs

It is recommended to use non-modal notifications instead of modal message boxes whenever appropriate. Refer to the Notifications topic for more information.

JBSplitter is a replacement for the standard JSplitPane class. Unlike some other JetBrains-enhanced Swing components, it is not a drop-in replacement and has a different API. However, to achieve a consistent user experience, it is recommended to use JBSplitter instead of the standard JSplitPane.

To add components to the splitter, call the setFirstComponent() and setSecondComponent() methods.

JBSplitter supports automatic remembering of the split proportion. To enable it, call the setSplitterProportionKey() method and pass the unique ID under which the proportion will be stored.

JBTabs is an implementation of the tab control, used for editor tabs and a few other components. It has a significantly different look & feel compared to the standard Swing tabs and looks less native on the macOS platform, so it's up to the developer to choose which tab control would be more appropriate.

See Toolbar in the UI Guidelines for an overview.
