When a Tree with no explicit columns is laid out with SWT.DEFAULT size hints (e.g. GridData(SWT.DEFAULT, SWT.DEFAULT)), the GTK preferred-size call on the not-yet-rendered GtkTreeView returns width 0. The resulting zero-width allocation triggers the ZERO_WIDTH hide path, making the widget invisible.

This is alternative fix for a similar problem to https://bugs.eclipse.org/bugs/show_bug.cgi?id=465056 but more dynamic. I'll switch Table to this approach too when we open next stream. |
