Debug toolbar is hidden

this issue was introduced a while ago when the effort to add simultaneous debugger support started. I haven't had time to report it till now.

The debug toolbar (showing the shortcuts for pausing, stopping, advancing execution) was hidden for gdb. I can make it visible again by deleting my existing configuration data entirely.

After doing all of the stuff below I don't have clang, but I do have gdb which is enough for what I want. I have tried to be accurate, but I am sure I left something out...

Attempt 1)

• Close qtc
• Delete all configuration files for qtc
• copying back in the xml files toolchains, debuggers, qtversions, profiles, devices, and gdbserverproviders
• Start qtc

Now compiling with and debugging with gcc/gdb results in the debug toolbar and all other debug windows being hidden for the duration of the debugging, only to be shown immediately after stoping the debugging.

Debugging with clang/lldb results in normal operation.

Under "Views" for gdb only "Editor" is selected.
Under "Views" for lldb all expected windows are shown.

Enabling the different views does not enable the toolbar.

Attempt 2)

• Close qtc
• delete debugger.xml, & QtCreator.{ini, db, conf}
• Start qtc
• add the debugger back, and fixing the toolchains.

At this point, gdb works.
Running lldb/clang does Not works.
Switching back to gdb and it still works.

Attempt 3)

• Close qtc
• Start qtc
• starting clang debug with no break point set

Result is that I can pause with lldb via qtc -> but the toolbar is gone again, but now for clang!

Attempt 4)

• Close qtc
• Start qtc
• start gdb with breakpoint set

qtc breaks as expected. Toolbar is still shown

• Start lldb/clang with breakpoint set

debug window still hidden

Attempt 5)

• Close qtc.
• delete QtCreator.{ini, db, conf}

The toolbar is now always visible, but clang breakpoints still don't work.

Attempt 6)

• Close qtc
• Start qtc
• start clang/lldb
• start gcc/gdb

The toolbar is hidden for clang but not gdb
