Description

Name: jk109818			Date: 09/18/2003


FULL PRODUCT VERSION :
java version "1.4.2_01"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_01-b06)
Java HotSpot(TM) Client VM (build 1.4.2_01-b06, mixed mode)

FULL OS VERSION :
Microsoft Windows 2000 [Version 5.00.2195]

A DESCRIPTION OF THE PROBLEM :
In Motif L&F JComboBox doesn't react when spacebar is pressed. Spacebar used for making selection in combobox as javadocs say. In Java (Metal) L&F it works fine - when I press spacebar popup window is being hidden, in Motif L&F popup window remains visible without any changes.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Compile and run my class. Press Arrow Down key when combobox has focus, than try to press Spacebar. If you want to see proper behavior comment out Motif L&F setting in 'main' method.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
When you press spacebar key popup list should disappear.
ACTUAL -
When you press spacebar key popup list remains visible.

REPRODUCIBILITY :
This bug can be reproduced always.

// Way to exit

	frMain.addWindowListener( new WindowAdapter()	{

		{
			frMain.dispose();
			System.exit( 0 );
		}

							} );

	jcbTest = new JComboBox( new String[] { "one", "two", "three" } );

	cntMain.add( new JLabel( "Select item by spacebar" ), BorderLayout.NORTH );
	cntMain.add( jcbTest, BorderLayout.CENTER );

	frMain.pack();
	frMain.setLocation( 200, 200 );

	frMain.show();

}
