Bug 320145

Description Heath Borders 2010-07-16 17:23:58 EDT

Build Identifier: 

On GTK, when a Combo has a black foreground (either by explicitly setting the foreground to black, or by using the system default and setting the foreground to null)  and a non-white background and the Combo's list is visibile, the list item over which the user is hovering has its foreground set to white.

This is not consistent with the behavior of windows.

Reproducible: Always

Steps to Reproduce:
public class GtkComboHoverBackgroundBug {
	public static void main(String[] args) {
		final Display display = new Display();
		final Shell shell = new Shell();
		shell.setLayout(new GridLayout());

		final Combo combo = new Combo(shell, SWT.READ_ONLY);
		combo.setBackground(new Color(display, new RGB(255, 255, 254)));
		combo.setForeground(new Color(display, new RGB(0, 0, 0)));
		combo.setItems(new String[] { "0", "1", "2", });
		combo.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, false));

		final Button button = new Button(shell, SWT.TOGGLE);
		button.addSelectionListener(new SelectionAdapter() {
			@Override
			public void widgetSelected(SelectionEvent e) {
				if (button.getSelection()) {
					combo.setForeground(new Color(display, new RGB(0, 0, 1)));
					button.setText("Switch to black");
				} else {
					combo.setForeground(null);
					button.setText("Switch to non-black");
				}
				shell.layout(true, true);
			}
		});
		button.setText("Switch to non-black");
		shell.open();
		while (!shell.isDisposed()) {
			if (!display.readAndDispatch()) {
				display.sleep();
			}
		}

		display.dispose();
	}
}
