On Wayland, many of the following warnings are printed in the error console: (SWT:7396): Gtk-WARNING **: Allocating size to GtkFrame 0x7f3228a387f0 without calling gtk_widget_get_preferred_width/height(). How does the code know the size to allocate? This most likely stems from some sort of bug in the SWT sizing machinery that needs to be treated differently on Wayland.
Eric reproduced it on non wayland env. Seems to be related just to latest gtk builds.

Pushed to master.
Still some allocation warnings in the console for GTK3.20. For example, this is printed when ControlExample runs: (SWT:9780): Gtk-CRITICAL **: gtk_box_gadget_distribute: assertion 'size >= 0' failed in GtkScrollbar (SWT:9780): Gtk-WARNING **: Negative content width -17 (allocation 1, extents 9x9) while allocating gadget (node entry, owner GtkEntry) (SWT:9780): Gtk-WARNING **: Negative content width -6 (allocation 1, extents 4x3) while allocating gadget (node toolbar, owner GtkToolbar) (SWT:9780): Gtk-WARNING **: Negative content width -6 (allocation 1, extents 4x3) while allocating gadget (node toolbar, owner GtkToolbar) (SWT:9780): Gtk-WARNING **: Negative content width -6 (allocation 1, extents 4x3) while allocating gadget (node toolbar, owner GtkToolbar) (SWT:9780): Gtk-WARNING **: Negative content width -6 (allocation 1, extents 4x3) while allocating gadget (node toolbar, owner GtkToolbar) (SWT:9780): Gtk-CRITICAL **: gtk_box_gadget_distribute: assertion 'size >= 0' failed in GtkScrollbar (SWT:9780): Gtk-CRITICAL **: gtk_box_gadget_distribute: assertion 'size >= 0' failed in GtkScrollbar
(eog:25201): Gtk-WARNING **: Allocating size to EogStatusbar 0x5638078b8ce0 without calling gtk_widget_get_preferred_width/height(). How does the code know the size to allocate?
These messages may also happen without running on Wayland (so you may consider this off topic) and this is what helped: export SWT_GTK3=0 /opt/eclipse/eclipse according to https://www.eclipse.org/forums/index.php/t/1081230/ This also resolved long delays for dialogs showing up when browsing Windows -> Preferences.
(In reply to Stefan from comment #7) > export SWT_GTK3=0 In case you'll ever want to use the internal browser I suggest you don't use this workaround. Here's why: 1. setting `SWT_GTK3=0` enforces SWT to use Gtk+ 2.x 2. SWT with Gtk+ 2.x can run the internal web browser with WebKit1 only. Gtk+ 3.x can run either WebKit1 or WebKit2. 3. Webkit1 is mostly unmaintained with dozens or hundreds of known security bugs. So you really only should continue using SWT with Gtk+ 2.x if you want to get hacked.

Move out of 4.7.
Created attachment 268870 [details] Snippet that causes failed assertion on GtkScrollbar This is seen after GTK3.20. The reason is that the preferred size of the text widget with Vertical scrollbar is more than 30 (in this case). We set it to 30 anyways and so everytime there is a redraw, it will cause the GTK Critical error.

Are there any other allocation warnings left or can we close this guy?
(In reply to Leo Ufimtsev from comment #16) > Are there any other allocation warnings left or can we close this guy? Yes there are still many. The commit in comment 15 only fixes a small corner case in the Group widget.

This causes a compile warning in our official build: http://download.eclipse.org/eclipse/downloads/drops4/I20170723-2000/compilelogs/plugins/org.eclipse.swt.tests.gtk_3.106.0.v20170721-1733/@dot.html WARNING in /Bug Snippets/org/eclipse/swt/tests/gtk/snippets/Bug519996_focusDisposeIssue.java (at line 18) CCombo combo1 = new CCombo(shell, SWT.BORDER); The value of the local variable combo1 is not used

Forgive me for what is likely a very noob question - is there an easy way I could test some of the changes made by this ticket? Specifically, I'm looking for what URL I could use to access p2 artifacts. Also, would the location contain changes for just this ticket, or all in-progress work towards Oxygen.1 ? Thanks!

If there is enough interest these changes can be backported into Oxygen -- currently this bug is (partially) fixed in 4.8. As for a p2 URL, you would have to update your Eclipse platform to 4.8 since none of these fixes are in 4.7 (Oxygen). However the best bet to try out these fixes is to download the latest milestone build, 4.8 M2. To do so, go to: http://download.eclipse.org/eclipse/downloads/ - Click on 4.8 M2. - Find your platform in the "Eclipse SDK". Download the archive, extract it and run the 'eclipse' binary. Bear in mind that you will have to use a new workspace since I don't think the 4.7 workspace will work with a 4.8 Eclipse.
I want to tack on an additional request for backporting into Oxygen.2 if possible. I support an RCP product that is currently getting hammered by these warning messages. We typically can't update our underlying Eclipse version prior to the official release, and waiting until June 2018 for the fix would be tough.

If this bug is partially fixed, please close this and raise a new bug with pending issues or move it to 4.9.
I have the same issue with Eclipse Photon on Ubuntu: when I launch an inner Eclipse from my dev env, I get a long list of this messages. (Eclipse:4277): GLib-CRITICAL **: 23:05:10.408: g_base64_encode_step: assertion 'in != NULL' failed Build ID information: Eclipse SDK Version: 4.9 Build id: I20180706-2000 OS: Linux, v.4.15.0-23-generic, x86_64 / gtk 3.22.30, WebKit 2.20.3 Java version: 1.8.0_171
I see a bunch of these warnings in gtk 3.22.30 (Debian testing). Furthermore, and this may be another issue, Eclipse gets less and less usable (both Photon and Oxygen). I see things like the main menu disappearing, double clicks not working correctly (e.g., selection in trees), rearranging of view leading to completely black screens, sometimes Eclipse recovers sometimes not. Not sure if this is related to the warnings. Any tips how I can help to find the cause and fix it? For example this is the warning output of an Eclipse Photon Modeling edition when rearanging a view: (Eclipse:8245): GLib-GObject-WARNING **: 21:20:05.165: ../../../../gobject/gsignal.c:3492: signal name 'attributes-changed' is invalid for instance '0x7fb8bc8dc5e0' of type 'GtkTextViewAccessible' (Eclipse:8245): Gdk-WARNING **: 21:20:11.967: Couldn't map window 0x7fb8bdf9b340 as subsurface because its parent is not mapped.

These warnings are probably due to eclipse running Wayland backend. Can you try setting GDK_BACKEND=x11?
(In reply to Xi Yan from comment #44) > These warnings are probably due to eclipse running Wayland backend. Can you > try setting GDK_BACKEND=x11? Thank you for the fast response. Yes this is fixing my issues. Sorry for posting to the wrong bug. Where and how can I support Wayland backend support for SWT?

Sorry, what I mean is that SWT should fix these warnings when running on Wayland.
