它是Emacs gdb-many-windows-mode中标题上的按钮还是标签？

Question

Some of the windows have clickable buttons or tabs on header in gdb-many-windows-mode such as 'Locals/Registers' or 'Breakpoints/Threads'. Are they tabs? Can I add new one next to them?

Answer 1

Buttons.

When gdb-many-windows is non-nil, the GDB Breakpoints buffer shares its window with the GDB Threads buffer. To switch from one to the other click with Mouse-1 on the relevant button in the header line. If gdb-show-threads-by-default is non-nil, the GDB Threads buffer is the one shown by default. Source

If you want to try and add buttons you'd probably have to expand gdb-mi.el. I am not sure whether that is possible without a hassle.
