GTK errors installing and using Netbeans 6 beta 1

[bonsiware]

Installing and using Netbeans 6 beta 1, everytime java draws a ComboBox control, terminal reports following errors:

(<unknown>:4339): Gtk-WARNING **: Attempting to add a widget with type GtkButton to a GtkComboBoxEntry (need an instance of GtkEntry or of a subclass)

(<unknown>:4339): Gtk-CRITICAL **: gtk_widget_realize: assertion `GTK_WIDGET_ANCHORED (widget) || GTK_IS_INVISIBLE (widget)' failed

(<unknown>:4339): Gtk-CRITICAL **: gtk_paint_box: assertion `style->depth == gdk_drawable_get_depth (window)' failed

(<unknown>:4339): Gtk-CRITICAL **: gtk_paint_box: assertion `style->depth == gdk_drawable_get_depth (window)' failed

It's reproducible opning netbeans and going to Tools-->Options (this window has a combobox control)

The control is not well drawn (see attachment)

The same errors happens if I launch Applications-->Internet-->Sun Java Web Start

(<unknown>:8616): Gtk-WARNING **: Attempting to add a widget with type GtkButton to a GtkComboBoxEntry (need an instance of GtkEntry or of a subclass)
(<unknown>:8616): Gtk-CRITICAL **: gtk_widget_realize: assertion `GTK_WIDGET_ANCHORED (widget) || GTK_IS_INVISIBLE (widget)' failed
(<unknown>:8616): Gtk-CRITICAL **: gtk_paint_box: assertion `style->depth == gdk_drawable_get_depth (window)' failed
(<unknown>:8616): Gtk-CRITICAL **: gtk_paint_box: assertion `style->depth == gdk_drawable_get_depth (window)' failed

and the combo box control is corrupted as in my new attachment...

now we know it's not a netbeans bug!!

there is someone talking about it in ubuntuforums too...

I have same problem using FileChooser and Java 6.03 from repos. under Gutsy.

[Antonio (antodasana)]

Same problem, JComboBox in ANY Swing Java application.

Is this an Ubuntu distribution error or a GTK+ one?

I think this is a severe problem to those who are developing Swing applications in Ubuntu.

[Jede28 (news-saring)]

I have the same problem. I think this is a Java bug in the GTK L&F implementation of Swing. The comboboxes in all other Swing application are looking fine.
BTW: the error "works" on all GTK+ themes, not just for the Human theme.

Bye,

Maybe, but I don't think so.

This bug has been reported in NetBeans and NB experts think it is a problem of new GTK+ in 7.10.

http://www.netbeans.org/issues/show_bug.cgi?id=118805

In my case, the bug was not happening in 7.04, I only had the bug after installing 7.10.

Anybody with the same case? Anyone having this bug also in 7.04?

[Jede28 (news-saring)]

Yes, you're probably right. The Netbeans guys haveI passed this bug to the GTK L&F maintainer in Java Swing. He said that this is a bug in the GTK library in Ubuntu Gutsy, it can't be fixed in Netbeans or Swing. So hopefully it will be fixed in Ubuntu.

This bug only happens since Ubuntu 7.10, not on 7.04. It happens on the Sun JVM's 1.5.0, 1.6.0 and also on the latest development releases of 1.6.0.

[Jede28 (news-saring)]

The bug has been accepted by Sun. Please go there and vote for it!

Reviewing this bug report and its comments it seems that multiple people are experiencing this problem. Subsequently, I am confirming this bug report.

I have the same problem when running NetBeans from terminal!

[Tails (tails9)]

Is it possible to suppress these warnings?

[Antonio (antodasana)]

It now works properly, at least in my case:

Product Version: NetBeans IDE 6.8 (Build 200912041610)
Java: 1.6.0_15; Java HotSpot(TM) Client VM 14.1-b02
System: Linux version 2.6.31-20-generic running on i386; UTF-8; es_ES (nb)

I guess the status of this bug should be updated.

Marking as fixed then.
