jtextfield

1) I was able to add a JTextField to the JFrame , and I initialized the class Java2sAutoTextField as given in Auto Complete JTextField (Swing / AWT / SWT / JFace forum at JavaRanch). 2) I initialized the list and field inside the JFrame constructor, as shown below. List possible = new ArrayList(); possible.add("Austria"); possible.add("Italy"); possible.add("Croatia"); possible.add("Hungary"); Java2sAutoTextField autoCompleter = new Java2sAutoTextField(possible); 3) The problem that arises is this: Even though I have initialized the Java2sAutoTextField , how can I apply auto completing to the

I'm writing a Java TextComponent where the underlying document has some structure. It is very short, basically one line. I need to be able to override the response to inserting or deleting characters in some parts of the document. My initial approach was to implement javax.swing.text.Document, but this seems to involve developing many associated classes (Element, EditorKit, View) and there don't seem to be many examples or tutorials on how to do this. There are plenty on using the pre-defined implementations. Can anyone point me at tutorials or other aids for simple implementations of Document

In text field more than 10 characters na, it has to show an error. For that i used document filter: JTextField field = (JTextField) txtFld; AbstractDocument document = (AbstractDocument) field.getDocument(); document.setDocumentFilter(new DocumentSizeAndUppercaseFilter(10)); So this is my document filter coding. I registered the textfield through document filter. But nothing has happening here. How to use document filter? DocumentSizeAndUppercaseFilter class which has the error msg. Without seeing the code for DocumentSizeAndUppercaseFilter I would suspect that you havn't implemented (

I am trying to limit the max length of character a user can input in a textfield but It seems to be not working. Here is the code: text2 = new JTextField("Enter text here",8); Is there anything I am doing wrong? How can I make the limit to work properly? Reimeus The constructor new JTextField("Enter text here",8); sets the number of visible columns to 8 but doesn't restrict you from entering more. You could use a DocumentFilter to restrict the input length. You current code is not setting the maximum length, rather it is defining the number of visible columns. To restrict the maximum length of

I have tried to keep my JTable 's tight and secure, making only editable columns editable via isCellEditable() . However, my clients are insisting that they want to double click on a cell so they can copy its contents, even if it is read only. I could let the cell be editable and not do anything with any edits they could make in the setValueAt() (so it reverts back to original value when editor exits). But I don't want this application to feel so freeform. Is there an easy effective way to make the JTextField used as the cell editor to allow selecting of text in the editor, but not editable? I
