Description of problem:
The eclipse window can be resized to an unusable small size

Version-Release number of selected component (if applicable):
eclipse-swt-4.7.0-2.fc26.x86_64

How reproducible:
always

Steps to Reproduce:
1. open eclipse
2. resize window to be as small as possible

Actual results:
Window only has decorations and menu bar, not even a toolbar or anything else.

Expected results:
Always show toolbar, statusbar, and all the views

Additional info:
This issue might be specific to wayland or the Gtk+ 3 build.

This issue is not specific to wayland and also affects other windows and
dialogs, e.g. the preferences dialog or the file properties dialog.

Christian,

This does not seem specific to GTK3 either. With GTK2 you can also make the
Eclipse window very small such that you can only see the decorations, with no
menu bar even. To me this feels like an RFE (it's probably working as designed,
and you can just make the dialog bigger again :-)

Leo,

What do you think of this as a possible enhancement? I notice that you cannot
shrink the native GTK dialogs (e.g. file open dialog) below a certain size, so
it might be nice if the SWT dialogs had the same behaviour.

Thanks for this explanation. If SWT is not setting minimum/preferred sizes for
its Gtk widgets, then this issue might be covered by
https://bugs.eclipse.org/bugs/show_bug.cgi?id=486068 already.

--- Comment #4 from Lev Ufimtsev <lufimtse(a)redhat.com&gt; ---
Thank you for your bug report.

I like the idea in principle :-), but current SWT api does not dictate minimum
size of a control. As such imposing one would break api and some applications
that rely on manual widget sizing.

There are some cases where you want smaller than minimum sizes. For example
when I make presentations on a low-resolution projector, I sometimes need to
make eclipse very very small, smaller than would be comfortable to use. But in
such situations I have no choice as I'm restricted by projector resolution. Or
sometimes I need to demonstrate a feature and size of windows is irrelevant. 

It's true that a super-tiny eclipse is not very usable, but most applications
can be shrunk down to a non-usable size. It's hard to determine a minimum size
that would work across all themes (considering different padding sizes),
resolutions, font-sizes, desktop managers, which at the same time would not be
"too big" in some cases.

We currently don't plan on implementing a hard-minimum size for the eclipse
window based on the real life limitations listed above. But if someone has an
idea/patches, they are welcome to share.

No, that patch is only specific to situations where widgets would get cut-off
due to padding. It doesn't touch window size.


Based on limitations above, if there is no reply/objections/feedback to my
comment, then I propose to close as wont_fix, as otherwise it's unlikely to get
implemented and would just float around Bugzilla for many years to come.

With that said, please do feel free to share further enhancement requests. They
are important to us. I think it's a good idea, but there are just real-life
barriers that make it impractical. 

I will followup on this bug next week.

Thanks Leo for the upstream perspective. Closing WONTFIX per your comment.
