I would think about something like:
-------------
public class TabbedPaneLayout implements LayoutManager {
protected int basePreferredTabAreaWidth(final int tabPlacement,
final int height) {
// TabbedPaneLayout preferredTabAreaWidth implementation
}
protected int truncatingPreferredTabAreaWidth(final int
tabPlacement, final int height) {
if (tabPlacement == SwingConstants.LEFT || tabPlacement ==
SwingConstants.RIGHT) {
return basePreferredTabAreaWidth(tabPlacement, height);
}
return basePreferredTabAreaWidth(tabPlacement, height);
}
protected int preferredTabAreaWidth(final int tabPlacement,
final int height) {
return basePreferredTabAreaWidth(tabPlacement, height);
}
}
class TabbedPaneScrollLayout extends TabbedPaneLayout {
@Override
protected int basePreferredTabAreaWidth(int tabPlacement, int
height) {
// TabbedPaneScrollLayout preferredTabAreaWidth implementation
}
}
protected class AquaTruncatingTabbedPaneLayout extends
AquaTabbedPaneCopyFromBasicUI.TabbedPaneLayout {
@Override
protected int preferredTabAreaWidth(final int tabPlacement,
final int height) {
return truncatingPreferredTabAreaWidth(tabPlacement, height);
}
}
protected class AquaTruncatingTabbedScrollPaneLayout extends
AquaTabbedPaneCopyFromBasicUI.TabbedPaneScrollLayout {
@Override
protected int preferredTabAreaWidth(final int tabPlacement,
final int height) {
return truncatingPreferredTabAreaWidth(tabPlacement, height);
}
}
-------------
I just have one more question. The TabbedPaneScrollLayout is only
created in AquaTabbedPaneCopyFromBasicUI. AquaLookAndFeel only use
AquaTabbedPaneUI or AquaTabbedPaneContrastUI which do not return
TabbedPaneScrollLayout.
Are there any real cases when the TabbedPaneScrollLayout is created?
When you enabled the AquaTruncatingTabbedScrollPaneLayout in the
AquaTabbedPaneUI the JTabbedPane L&F with SCROLL_TAB_LAYOUT does not
look similar to Aqua L&F:
http://cr.openjdk.java.net/~alexsch/8137169/aqua-scrolled-tabbed-pane.png
The AquaTruncatingTabbedPaneLayout already contains arrows for hidden
tabs navigation.
May be the fix should update the AquaTruncatingTabbedPaneLayout only?
Thanks,
Alexandr.
