Hi all,

Gallery Widget virtual mode crashed when using SWT 4.9 on Mac this is the error :

java.lang.NullPointerException: Cannot invoke "org.eclipse.swt.internal.cocoa.NSGraphicsContext.graphicsPort()" because "graphicsContext" is null at org.eclipse.swt.widgets.Control.internal_new_GC(Control.java:2180) at org.eclipse.swt.graphics.GC.(GC.java:177) at org.eclipse.nebula.widgets.gallery.DefaultGalleryGroupRenderer.pre(DefaultGalleryGroupRenderer.java:574) at org.eclipse.nebula.widgets.gallery.DefaultGalleryGroupRenderer.preLayout(DefaultGalleryGroupRenderer.java:560) at org.eclipse.nebula.widgets.gallery.Gallery.calculateSize(Gallery.java:1560) at org.eclipse.nebula.widgets.gallery.Gallery.updateStructuralValues(Gallery.java:1525) at org.eclipse.nebula.widgets.gallery.Gallery.setItemCount(Gallery.java:259)

Best Regards, Ivan

Hi What version of OSX do you use ? SWT had problems with Big Sur

It looks like this bug was solved in SWT. It was pushed also to 4_6 maintenance but I don't know how to build this from source.

It does not look like a Nebula issue.

Hi, I'm using Mac OS 10.15

Thanks

This SWT bug (look at the bugzilla issue 547 399) has been fixed for version 4.12 and backported to 4.6,4.7 and 4.8 (but not 4.9). Can you try with 4.8 : https://archive.eclipse.org/eclipse/downloads/drops4/R-4.8-201806110500/download.php?dropFile=swt-4.8-cocoa-macosx-x86_64.zip

I confirm that this is not a Nebula bug but a SWT one

Hi, sorry for my late reply. Yes, you;re right. no issues with 4.8 except 4.9 thanks again
