Thread: Getting a TextField to activate ItemListener.

I'm having it choose songs from a hymn book and set the page number to a certain page if they chose a certain song name from a JComboBox. This I know how to do. However, I would also like it to do it the other way around by having it, if a certain page number is entered in the text field, get it to set the song selected in the JComboBox. I thought it would be simple, but it's not working out. Do I need a bunch of KeyListeners?

Also, in that same program, I have fonts that will be selected but I can't figure out how it'll know which font to change size and/or style. What Font method do I call to get the font type from the text area and then call deriveFont() to change the size and/or style of that font? Should I use the getFont() or getFontName() method or some other method?

Also, I realize now I could have used JComboBoxes for the Colors, but it's too late by the time that occurred to me, plus I was experimenting with JRadioButton and ButtonGroup anyway.

Also, my JTextField is somehow coming out too big and acting too much like a JTextArea. Except it only has one line, though it can get going on that one line

like this

----------------------------------------------------------------------------------------------------------------------------

that's why I mean by one line.

I only set it for 3.

Must be my layout. I wish I could get a nicer layout, but how do you do that?

Ok, How do I add a key listener to handle it if two or more keys are typed?

Like if I typed 12 or 150.

Is it:

KeyEvent e;

if (e.getKeyChar() == VT_A + VT_B)

for AB or ab ?

You can use a DocumentListener to listen for changes to the text inside JTextComponents.

To add a document listener:

((AbstractDocument)theTextField.getDocument()).addDocumentListener(theListener);

Document listeners allow you to listen for when the text inside the text box actually changes. So, you only have to change the combo box's select when the text changes. You can also just parse the number inside the text field and not worry about any lower-level key press processing which may work, but is very difficult to have it correct in all cases.
