Hi all,
I've noticed two issues which seem to occur only on Linux systems. We
tried two Linux machines using Kubuntu 15.10 with KDE Plasma 5.5.3, one
Mac and a Windows 8 installation. On Mac and Windows it works, but not
on Linux.
1. It is not possible to get the grid visible. Tried various colours and
styles, but it is simply not shown.
2. When entering direct editing using F2 or two mouse clicks all text is
selected per default. This selected text has white text colour on white
background and is therefore invisible. This happens only for direct
editing; selecting text in the properties view for example has white
text colour on blue background.
My questions:
1. Can anybody confirm this behaviour on a Linux machine using the same
or another setup (distribution, window manager, versions, theme)?
2. If yes, is this a GTK or a Sirius bug?
3. Any idea about what I could try to get the grid visible? If not I
could still remove the grid by default (as it is a nice-to-have
requirement), so that the same look n feel is used for all operating
systems.
4. The 2nd issue is more important, since it affects basic usage. Would
it be possible to take influence on the colours used in direct editing
somehow? I've tried changing several colours in general preferences
("General > Appearance > Colours and Fonts" as well as "General >
Editors > Text Editors") and Sirius preferences ("Sirius > Sirius
Diagram > Appearance"), but didn't cope with causing a change. Also I've
looked at GEF sources, but did not find out anything useful yet except
that the DirectEditManager class cares for creating and disposing a cell
editor as well as an IFigure.
Thank you very much,
Axel

This is an issue we've already encountered, see
https://bugs.eclipse.org/bugs/show_bug.cgi?id=435878. It looks like it's
not specific to Sirius (we reproduced it using plain GMF diagrams), and
it's probably in the Draw2D layer and/or SWT/Gtk/Cairo.
Unfortunately, it seems highly system dependant. A recent post on the
GMF forum where we mentioned the issue almost 2 years ago even indicates
it could depend on the graphics driver used
(https://www.eclipse.org/forums/index.php/t/780844/).

I don't believe we have customized anything in Sirius in this area
compared to the default GEF/GMF behavior. IIRC the colors are taken from
the system theme. On my machine, under GNOME, I get white text on blue
background when using the Adwaita theme, and white text on orange
background when using Ambiance. Do you get a different color when
chaning theme?

Thanks. I postponed this issue for now.

No, unfortunately not. I tried several designs and colour schemes and
even changed the colour for selected text explicitely - all without any
effect.
Would it be possible to initially deselect the text when direct editing
starts? Is there any entrypoint to hook in custom code for that purpose?
Thanks,
Axel

Just a follow-up information: the 2nd problem related to direct-editing
is gone with Neon and Sirius 4.0!
