Linux: widths of toolbar items

Thomas Singer
Hello,

I've played a little bit with texts of toolbar items on Ubuntu 16.04 and
noticed some really unexpected behavior. Sometimes it looks like all
items are made as wide as the largest item, sometimes it looks like the
toolbar has some overall size that is distributed among the containing
items, sometimes the item's image was centered horizontally within the
item while the text was left-aligned. A real logic I haven't found out.

Please take a look at the screenshots I've added to following bug:

<https://bugs.eclipse.org/bugs/show_bug.cgi?id=512716>

illustrating one part of the problem.

I vaguely remember to have seen a similar problem years ago, where some
"key words" have increased the tool items significantly - I even thought
to have reported this bug, but could not find it again.

Re: Linux: widths of toolbar items

Hello,

We have a long-standing problem that opening the Log window in SmartGit
caused to hang with 100% CPU on Linux under special conditions. Now it
could be narrowed by users to a screen scaling factor of 1.25.

After being able to reproduce and intensive debugging I've found out
that this problem was also toolbar related. Setting a separator's width
so the overall toolbar width came at ~1200 pixels at the wrong time (not
yet visible) caused an endless loop of always the same event being
received and processed. Unfortunately, I've did not yet succeeded in
extracting a snippet to reproduce outside SmartGit. I just mention it
because there is something really odd going on with toolbars and
toolitem width on Linux.
