#210 GridControl scrollbar doesn't paint in Nimbus LaF

[Anonymous]

GridControl scrollbar doesn't paint when I use Nimbus Look and Feel.

ClientSettings.LOOK_AND_FEEL_CLASS_NAME = "com.sun.java.swing.plaf.nimbus.NimbusLookAndFeel";

If I don't set the look and feel, openswing will use Metal LaF by default. The scroll bar, down/up arrow and prev/next page arrow are painted correctly.

My environment is:
Ubuntu 11.04

$ java -version
java version "1.6.0_26"
Java(TM) SE Runtime Environment (build 1.6.0_26-b03)
Java HotSpot(TM) Server VM (build 20.1-b02, mixed mode)

Openswing2.4.2

Please see attached picture.

Hi All,

I think I found the source of the problem which is in PaginationVerticalScrollbar class.
---------------------
public void updateUI() {
if (!ClientSettings.SHOW_PAGINATION_BUTTONS_ON_GRID) {
super.updateUI();
return;
}
try {
ScrollBarUI ui = (ScrollBarUI) UIManager.getUI(new JScrollBar());
if (ui.getClass().getName().endsWith("MetalScrollBarUI")) {
setUI(MetalPaginationVerticalScrollbarUI.createUI(this));
}
else if (ui.getClass().getName().endsWith("MacScrollBarUI")) {
ComponentUI cui = (ComponentUI)Class.forName("org.openswing.swing.table.client.MacPaginationVerticalScrollBarUI").getMethod("createUI",new Class[]{JComponent.class}).invoke(null,new Object[]{this});
setUI(cui);
}
else {
setUI(WindowsPaginationVerticalScrollbarUI.createUI(this));
}
}
catch (Throwable ex) {
setUI(WindowsPaginationVerticalScrollbarUI.createUI(this));
}
}
--------------------

In above code, WindowsPaginationVerticalScrollbarUI is the default UI if appropriate vertical scrollbar UI is not defined. In my opinion the default should be MetalScrollBarUI since it is cross platform. I changed that method as follow and has tested in Ubuntu and Windows XP.

public void updateUI() {
if (!ClientSettings.SHOW_PAGINATION_BUTTONS_ON_GRID) {
super.updateUI();
return;
}
try {
ScrollBarUI ui = (ScrollBarUI) UIManager.getUI(new JScrollBar());
if (ui.getClass().getName().endsWith("WindowsScrollBarUI")) {
setUI(WindowsPaginationVerticalScrollbarUI.createUI(this));
} else if (ui.getClass().getName().endsWith("MacScrollBarUI")) {
ComponentUI cui = (ComponentUI)Class.forName("org.openswing.swing.table.client.MacPaginationVerticalScrollBarUI").getMethod("createUI",new Class[]{JComponent.class}).invoke(null,new Object[]{this});
setUI(cui);
} else {
setUI(MetalPaginationVerticalScrollbarUI.createUI(this));
}
}
catch (Throwable ex) {
setUI(MetalPaginationVerticalScrollbarUI.createUI(this));
}
}
