Set focus on JComboBox

JComboBox dBox = new JComboBox(dLists);
dBox.addActionListener(this);
dBox.setActionCommand("Combo1");
dBox.requestFocus();

but the combobox doesn't get focus.

thanks

Try an updateUI () call for your container (which contains the JComboBox) after requestFocus ().

You better wait to perform

         dBox.requestFocus();

until it is really needed and after all (window/frame/dialog) initialization is done.

Maybe you can post more complete code

You really need to do this in a window listener if you want this to happen as soon as your app is shown. See

http://javaalmanac.com/egs/java.awt/focus_InitialFocus.html

Can it not be done in a statement just after show () or setVisible ( true ) ?

I mean - the updateUI () ?

Try it:


combo.requestFocusInWindow();


I hope that it  helps,

i solve the problem by using coding below:

myFrame.setResizable(false);
dBox.requestFocus();
myFrame.setVisible(true);

any disadvantage on above code?

thanks

If what i first suggested is working, then stick with that

sure i will but just want to know any disadvantage on it?

Not having a deep enough knowledge of focus - i'd probably resort to trial and error myself ;-)
