| <h3 class="section">25.4 TUI-specific Commands</h3> |
| |
| <p><a name="index-TUI-commands-2932"></a> |
| The TUI has specific commands to control the text windows. |
| These commands are always available, even when <span class="sc">gdb</span> is not in |
| the TUI mode. When <span class="sc">gdb</span> is in the standard mode, most |
| of these commands will automatically switch to the TUI mode. |
| |
| <p>Note that if <span class="sc">gdb</span>'s <code>stdout</code> is not connected to a |
| terminal, or <span class="sc">gdb</span> has been started with the machine interface |
| interpreter (see <a href="GDB_002fMI.html#GDB_002fMI">The <span class="sc">gdb/mi</span> Interface</a>), most of |
| these commands will fail with an error, because it would not be |
| possible or desirable to enable curses window management. |
| |
| <dl> |
| <dt><code>tui enable</code><dd><a name="index-tui-enable-2933"></a>Activate TUI mode. The last active TUI window layout will be used if |
| TUI mode has prevsiouly been used in the current debugging session, |
| otherwise a default layout is used. |
| |
| <br><dt><code>tui disable</code><dd><a name="index-tui-disable-2934"></a>Disable TUI mode, returning to the console interpreter. |
| |
| <br><dt><code>info win</code><dd><a name="index-info-win-2935"></a>List and give the size of all displayed windows. |
| |
| <br><dt><code>layout </code><var>name</var><dd><a name="index-layout-2936"></a>Changes which TUI windows are displayed. In each layout the command |
| window is always displayed, the <var>name</var> parameter controls which |
| additional windows are displayed, and can be any of the following: |
| |
| <dl> |
| <dt><code>next</code><dd>Display the next layout. |
| |
| <br><dt><code>prev</code><dd>Display the previous layout. |
| |
| <br><dt><code>src</code><dd>Display the source and command windows. |
| |
| <br><dt><code>asm</code><dd>Display the assembly and command windows. |
| |
| <br><dt><code>split</code><dd>Display the source, assembly, and command windows. |
| |
| <br><dt><code>regs</code><dd>When in <code>src</code> layout display the register, source, and command |
| windows. When in <code>asm</code> or <code>split</code> layout display the |
| register, assembler, and command windows. |
| </dl> |
| |
| <br><dt><code>focus </code><var>name</var><dd><a name="index-focus-2937"></a>Changes which TUI window is currently active for scrolling. The |
| <var>name</var> parameter can be any of the following: |
| |
| <dl> |
| <dt><code>next</code><dd>Make the next window active for scrolling. |
| |
| <br><dt><code>prev</code><dd>Make the previous window active for scrolling. |
| |
| <br><dt><code>src</code><dd>Make the source window active for scrolling. |
| |
| <br><dt><code>asm</code><dd>Make the assembly window active for scrolling. |
| |
| <br><dt><code>regs</code><dd>Make the register window active for scrolling. |
| |
| <br><dt><code>cmd</code><dd>Make the command window active for scrolling. |
| </dl> |
| |
| <br><dt><code>refresh</code><dd><a name="index-refresh-2938"></a>Refresh the screen. This is similar to typing <kbd>C-L</kbd>. |
| |
| <br><dt><code>tui reg </code><var>group</var><dd><a name="index-tui-reg-2939"></a>Changes the register group displayed in the tui register window to |
| <var>group</var>. If the register window is not currently displayed this |
| command will cause the register window to be displayed. The list of |
| register groups, as well as their order is target specific. The |
| following groups are available on most targets: |
| <dl> |
| <dt><code>next</code><dd>Repeatedly selecting this group will cause the display to cycle |
| through all of the available register groups. |
| |
| <br><dt><code>prev</code><dd>Repeatedly selecting this group will cause the display to cycle |
| through all of the available register groups in the reverse order to |
| <var>next</var>. |
| |
| <br><dt><code>general</code><dd>Display the general registers. |
| <br><dt><code>float</code><dd>Display the floating point registers. |
| <br><dt><code>system</code><dd>Display the system registers. |
| <br><dt><code>vector</code><dd>Display the vector registers. |
| <br><dt><code>all</code><dd>Display all registers. |
| </dl> |
| |
| <br><dt><code>update</code><dd><a name="index-update-2940"></a>Update the source window and the current execution point. |
| |
| <br><dt><code>winheight </code><var>name</var><code> +</code><var>count</var><dt><code>winheight </code><var>name</var><code> -</code><var>count</var><dd><a name="index-winheight-2941"></a>Change the height of the window <var>name</var> by <var>count</var> |
| lines. Positive counts increase the height, while negative counts |
| decrease it. The <var>name</var> parameter can be one of <code>src</code> (the |
| source window), <code>cmd</code> (the command window), <code>asm</code> (the |
| disassembly window), or <code>regs</code> (the register display window). |
