textchanged

in C# there is an event for textboxes as follows private void fooText_TextChanged(object sender, EventArgs e) { //do something } the code in the fooText_TextChanged is fired once the text within the textbox is altered. What is the java equivalent to this? Or how can something similar to this be achieved in java? Thanks for any feedback/help/advice. For Swing, If you wanted to be notified after the text component's text had changed, you'd use a DocumentListener that was added to the JTextComponent's Document. e.g., JTextField myField = new JTextField(); myField.getDocument().addDocumentListener

On a wpf TextBox that has an TextChanged event, it seems to only fires when focus is taken away from the textbox; but not as individual characters are typed in. Is there an event similar to TextChanged that fires immediately when a character is typed into the textbox, rather than when focus changes? You can bind the Text property and make use of the UpdateSourceTrigger . UpdateSourceTrigger=PropertyChanged By setting it to PropertyChanged , you will get a notification each and every time the text changes. TextChanged does fire as soon as the text is changed. (If you have a binding on Text that
