How to avoid focus()..?

[ehochedez]

Sorry for my poor English..

I'm trying to make an application which NetBeans using Swing and on my first jFrame i have a textField. My problem is that when i start the application this textfield gets directly focused on, and i don't want that, i want nothing to be focused on. Besides when i click somewhere else on the frame after where there is no object, the textField keeps beeing focused..
Does someone know how to avoid that?

Set the requestFocus(false) on the textFieldComponent .U can do this for any component.

Example

JTextField field1 = new JTextField( 10 );

field1.requestFocus(false);

Did you read the API specs for that method to see what it really does?

@OP You can stop a component from getting focus by setting

field.setFocusable(false)

. When that button is clicked you can then set it back to true and request the focus for the field when you need it.

Thanks Ramya for your reply.
I tried to use .requestFocus(false) on my textField but it doesnt work, it doesn't change anything..
And i also tried setRequestFocusEnable(false) but it also doesnt work, worse if i click on another button or textField, then i can't foncus on my 1st textField anymore..

Any other idea?

Could you please send the code ?

Of course it doesn't work. It's wrong. Read my response above.
Also read the API specs.

I join the code.
I also want that everytime someone click on a textField, a virtual keyboard appeared at the bottom of the Frame (it is for touch screens)(this part is already working, it's just to explain the code)

You are not describing your requirements accurately.
First you said you want them to be focused after a button is clicked now you say you want them to be focused they they are clicked. That is different.

Just add a MouseListener to it

                textfield.setFocusable(false);
		textfield.addMouseListener(new MouseAdapter() {
			@Override
			public void mouseClicked(MouseEvent e) {
				textfield.setFocusable(true);
				textfield.requestFocusInWindow();

			}
		});
