Description Paul Webster

+++ This bug was initially created as a clone of Bug #376442 +++

CDT provides a feature to allow to do reverse debugging (step backwards).

When reverse debugging is possible, CDT makes visible 4 new buttons on the
debug toolbar: "reverse step into", "reverse step over", "reverse resume", and
"uncall" (reverse step return).

This small howto shows screenshots of the buttons and how to enable them:
http://wiki.eclipse.org/CDT/User/FAQ#How_do_I_do_Reverse_Debugging.3F

The problem is that when the 4 new buttons become visible (or invisible), the view toolbar does not redraw properly to make room (or remove room) for the new buttons.

After resizing the view, the toolbar is redrawn nicely.

Attached is a screenshot showing:
1- the normal toolbar
2- the proper toolbar with the extra buttons after a resize of the view
3- the error where buttons were hidden and the view toolbar has extra space
4- the error where buttons were made visible and the view is truncating buttons

If I can help get more information, please let me know.

To reproduce that problem, if you have time, please do the following:
1- run on linux with a GDB version >= 7.0
2- Debug your HelloWorld program in CDT
3- Customize perspective to enable the action set "Reverse Debugging"
4- A new icon should appear on the debug view toolbar (double arrow with clock)
=> This new icon hides the view menu icon

5- Press the new button
6- some reverse debugging buttons should appear on the debug view toolbar 
=> The Debug view toolbar is truncated on the right
7- Minimize then maximize the view to make the toolbar redraw

Paul, I have a hacked up view that might be helpful...it adds two new actions (both menu / tb) one of which adds a new action the other removes the last(?) one.

Let me know if you want me to attach it...

This should be fixed with Bug 431990.

This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. As such, we're closing this bug.

If you have further information on the current state of the bug, please add it and reopen this bug. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.
