25.4 TUI-specific Commands

The TUI has specific commands to control the text windows. These commands are always available, even when GDB is not in the TUI mode. When GDB is in the standard mode, most of these commands will automatically switch to the TUI mode.

Note that if GDB’s stdout is not connected to a terminal, or GDB has been started with the machine interface interpreter (see The GDB/MI Interface), most of these commands will fail with an error, because it would not be possible or desirable to enable curses window management.
