Aligning JMenu on the right corner of JMenuBar in Java Swing

Question

So if i have a JMenu & JMenuBar defined such that:

jMenuBar1 = new javax.swing.JMenuBar();
jMenu1 = new javax.swing.JMenu();
jMenu1.setText("About");
jMenuBar1.add(jMenu1);

// Finally
setJMenuBar(jMenuBar1);

and with this the Menu "About" is aligned to the left most side of the menu bar. Is there anyway that i can align this menu on the right most side of the menu bar?

Answer 1

There is a patch available for this:

jMenuBar.add(Box.createHorizontalGlue());

Add this line before adding menu to menubar and your menu will come on right side of menubar. Something like:

.....
jMenu1.setText("About");
jMenuBar1.add(Box.createHorizontalGlue()); <-- horizontal glue
jMenuBar1.add(jMenu1);
.....

Answer 2

jMenuBar1.add(Box.createHorizontalGlue());

并且不要忘记将JMenu与JMenuItem对齐

JMenu.setComponentOrientation(ComponentOrientation.RIGHT_TO_LEFT); 

Answer 3

正如mKorbel对于JMenu所说的那样，它可以像这样在JMenuBar上工作：

    jMenuBar1.setComponentOrientation(ComponentOrientation.RIGHT_TO_LEFT);

Answer 4

Your may refer to https://docs.oracle.com/javase/tutorial/uiswing/layout/box.html

Especially take a note on part

by putting horizontal glue between two components in a left-to-right box, you make any extra space go between those components
