I just moved on to try swt package for gettting baseWindow handle.But
webNavigation is not happening.This is what I have done.Using
xulrunner1.8.1.2 jars / eclipse3.2.2 and swt package.
Display display = new Display();
Shell shell = new Shell(display);
shell.setBounds(300, 300, 300, 300);
shell.setText("Main Window");
TestGTK gtk = new TestGTK(shell,SWT.EMBEDDED);
gtk.initDisplay(shell);
shell.open();
gtk.test();
while (!shell.isDisposed())
{
if (!display.readAndDispatch())
display.sleep();
}
display.dispose();
}
void initDisplay(Composite parent)
{
Display display = parent.getDisplay();
display.setData(NO_INPUT_METHOD, null);
}
public void test()
{
// gre initialization

mozilla.initialize(grePath);
mozilla.initEmbedding(grePath, grePath, locProvider);

progress.addProgressListener((nsIWebProgressListener)listener,nsIWebProgress.NOTIFY_ALL);
System.out.println("Step7: nsIWebProgressListener added

//appStartup.run();
}
int createWindowHandle()
{
String osname=System.getProperty("os.name");
System.out.println("osname "+osname);
int embed_handle = OS.gtk_hbox_new (false, 0);
OS.gtk_container_add (this.handle, embed_handle);
OS.gtk_widget_show (embed_handle);
return embed_handle;
}
Need help.I have no exceptions or errors.
regards,
