Debug tool window

This tool window becomes available when you start debugging.

It displays the output generated by the debugging session for your application. If you are debugging multiple run/debug configurations, the output for each configuration is displayed in a separate tab named after the corresponding configuration.

For each configuration, there are the following nested tabs:

  • Console: displays system information and error messages, and the console input and output of your application.

  • Debugger: this tab is divided into the following areas:

Each area has a context menu that allows you to configure its behavior and navigate between tabs.

Each of the tabs and areas can be hidden/restored, or moved to a location of your choice.

Moving tabs and areas

If you are unhappy with the default layout of the Debug tool window, you can always move the tabs and areas. To do that, just drag a tab or an area to the desired location. The possible target gets highlighted.

Drop the tab or area in the highlighted location.

To restore the default layout of tabs and area, click Restore layout in the Debug toolbar.

Context menu of a tab

Use the context menu of the Frames, Variablesor Watches areas to configure the behavior of these areas or navigate between tabs.

You can temporarily mute all the breakpoints in a project to execute the program without stopping at breakpoints.

Stepping toolbar

ItemTooltip and ShortcutDescription
Show Execution PointShow Execution Point
Alt+F10
Click this button to highlight the current execution point in the editor and show the corresponding stack frame in the Frames pane.
Step overStep Over
F8
Click this button to execute the program until the next line in the current method or file, skipping the methods referenced at the current execution point (if any). If the current line is the last one in the method, execution steps to the line executed right after this method.
Step intoStep Into
F7

Click this button to have the debugger step into the method called at the current execution point.

Step outStep Out
Shift+F8
Click this button to have the debugger step out of the current method, to the line executed right after it.
Run to cursor Run to Cursor
Alt+F9

Click this button to resume program execution and pause until the execution point reaches the line at the current cursor location in the editor. No breakpoint is required. Actually, there is a temporary breakpoint set for the current line at the caret, which is removed once program execution is paused. Thus, if the caret is positioned at the line which has already been executed, the program will be just resumed for further execution, because there is no way to roll back to previous breakpoints. This action is especially useful when you have stepped deep into the methods sequence and need to step out of several methods at once.

If there are breakpoints set for the lines that should be executed before bringing you to the specified line, the debugger will pause at the first encountered breakpoint.
