jcombobox

问题 I have a JTree that I'm filling with skills for a Game Database programme that I'm writing. There are several categories, and subcategories (actual skills), and then levels skill below that (sometimes). Currently I'm emulating this with one skill class, some options inside, and a few enums, plus a method to check that if the skill is a category (called isCategory). Two other things to note: Different types of skill behave differently. Some are bought once, other several times, some have

问题 I w'd like make a JComboBox that contents could be searchable. I tried AutoCompleteDecorator, GlazedLists, SwingLabs, JIDE, Laf-Widget , but all of the cannot search by second keyword. For example, in this code possible search by 1st letter and this content includes just one word. this.comboBox = new JComboBox(new Object[] { "Ester", "Jordi", "Jordina", "Jorge", "Sergi" }); AutoCompleteDecorator.decorate(this.comboBox); If JComboBox content consists 2 or 3 words, for example: "Ester Jordi" or

问题 I keep searching and it seems like everybody is using only the JComboBox#getSelectedItem . But my combo box is editable and the user can enter anything . The getSelectedItem method returns one of the actual items in the combo box, not a string entered in the field. If my box contains "Bar" and "Item" and user enters "Foo", I want to get "Foo"!

问题 This may be a question asked before. I searched a lot before posting here, but couldn't figure out any acceptable one. Can some one show me a way how to do this.

问题 Is it possible to hide the arrow displayed in the JComboBox I tried setting: combo.getComponent(0).setSize(new Dimension(1,1)); But it doesnt seem to work 回答1: You have to create a new combobox UI for that: combo.setUI(new BasicComboBoxUI() { protected JButton createArrowButton() { return new JButton() { public int getWidth() { return 0; } }; } }); But be careful to inherited from the base UI which matches your current look and feel.

问题 I'm trying to use a compound Swing component as part of a Menu.
