Internal Actions - UI Inspector
The UI Inspector is a tool to interrogate elements of the IntelliJ IDEA UI to get an internal description of each element. UI elements can be inspected interactively by clicking on the element while the UI Inspector is enabled.
Enabling the UI Inspector
Before using the UI Inspector, it must be enabled by selecting the menu item . The enabled state of the UI Inspector is modal; it remains enabled until it is disabled by selecting the UI Inspector menu item again.
Using the UI Inspector
While enabled, centering the cursor on a UI element and pressing Ctrl/Cmd+Alt when clicking the mouse reveals the properties of the Swing component.
