right aligning tab names

Thread view:

I have a JTabbedPane and add tabs using a vertical tab placement policy
[e.g., jtabpane.setTabPlacement(SwingConstants.RIGHT);]

Unfortunately, as I add tabs (e.g., jtabpane.addTab(tabName, component)), it
centers the tab name in the middle of tab. I'd like to control this and
right align the placement of these tab names.

I don't see anything in the API as to how this can be done? Is it possible?

try
JTabbedPane.setOrientation(ComponentOrientation.LEFT_TO_RIGHT/ComponentOrien
tation.RIGHT_TO_LEFT);

Thanks, but no luck. Didn't see any menthod in JTabbedPane called
setOrientation(...)

I did find this:
jTabbedPane.setComponentOrientation(ComponentOrientation.RIGHT_TO_LEFT);
jTabbedPane.applyComponentOrientation(ComponentOrientation.RIGHT_TO_LEFT);

But, this didn't work either.

yes setComponentOrientation ir right one.

then you have to write your own AlignedTabbedPaneUI:

public class AlignedTabbedPaneUI extends BasicTabbedPaneUI {

public static ComponentUI createUI(JComponent c) {
return new AlignedTabbedPaneUI ();
}

protected void layoutLabel(int tabPlacement,
FontMetrics metrics, int tabIndex,
String title, Icon icon,
Rectangle tabRect, Rectangle iconRect,
Rectangle textRect, boolean isSelected ) {
textRect.x = textRect.y = iconRect.x = iconRect.y = 0;
SwingUtilities.layoutCompoundLabel((JComponent) tabPane,
metrics, title, icon,
SwingUtilities.CENTER,
SwingUtilities.LEADING, //changed
from CENTER to LEADING
SwingUtilities.CENTER,
SwingUtilities.TRAILING,
tabRect,
iconRect,
textRect,
textIconGap);

int xNudge = getTabLabelShiftX(tabPlacement, tabIndex, isSelected);
int yNudge = getTabLabelShiftY(tabPlacement, tabIndex, isSelected);
iconRect.x += xNudge;
iconRect.y += yNudge;
textRect.x += xNudge;
textRect.y += yNudge;
}
}

That worked! Looking at this class, it seems like you can have a lot of
control over the layout of the tabs once you study how it puts thing
together.

Thanks again.

To hardcode text align is just a mistake.
Such things are _properties_ and should be accessible without writing new
ComponentUI.
