jcombobox

I want to create a JTable where in a specific column named "Tools" a JComboBox should be accommodated. the values of the JComboBox should differ for each row. In the constructor I have the following piece of code: public Table(List<Software> software_list) throws TransformerFactoryConfigurationError, TransformerException, Exception { //****** create an 2D array object containing the emulators list data to be sent to the table model ****** software_list_to_array = new Object[software_list.size()][5]; for(int x = 0; x < software_list_to_array.length; x++){ software_list_to_array[x][0] = software

I'm looking for a way to alter the width of a JComboBox's popup. Basically, the popup should be as wide as the widest combobox entry requires, not as wide as the combobox currently is. The only way I know how to achieve this is creating a custom instance of ComboBoxUI and set that on the JComboBox (Example code demonstrates the goal: Top Combobox shows wide popup, Bottom is the default behavior). However since this replaces the UI of the ComboBox, it may look odd on some L&F's (For example with WinXP Luna theme the ComboBox looks like Classic theme). Is there a way to achieve this behavior in

I have multiple comboboxes in my GUI which all need to have the data. This data will change at random so a quick way to keep all values synced is needed. I encountered DefaultComboBoxModel which actually fits quite perfect. Only thing is, that I need the comboboxes to be independent of each other - meaning: if I select a value on one, all others shouldn't change. I've done a bit of research and read the standard java tutorials but none tell me really how to achieve this with the DefaultComboBoxModel. This example here exactly illustrates what I need: Sharing the Data Model between two

A person wishes to add a NEW Job to the database. A Combobox list the existing employers already in the database for the new Job to be added against. But if an employer is not present customers have the option click on a button to add an employer. Once added that employer should immediately be displayed in the textfield. I am trying to achieve the above scenario with my coding and mysql database, but cant think of the logic to do so... Table Employer CREATE TABLE "Employer" ("employerID" INTEGER PRIMARY KEY NOT NULL , "name" CHAR, "industry" CHAR, "contact1" CHAR, "contact2" CHAR, "email" CHAR

I'm trying to display database item into a JComboBox and this is my code. public static void checkItemName(){ Connection conn = SQLite.SQLite(); String sql = "select itemname from item"; try{ Statement statement = conn.createStatement(); ResultSet resultSet = statement.executeQuery(sql); while (resultSet.next()){ String list = resultSet.getString("itemname"); purcItemName.addItem(list); conn.close(); } } catch (SQLException lol){ System.out.println(lol.toString()); } } I did declare static JComboBox purcItemName; and purcItemName = new JComboBox(); The method/function will be called then user

I have a JComboBox where the items are the results of a query. The combo shows all the categories names taken from a query, right? Ok, it works. Now I need to give each item a value, which would be the ID of the product. This is what I've got so far: final JComboBox proveedorCombo = new JComboBox(); contentPanel.add(proveedorCombo); ProveedorDAO dao = new ProveedorDAO(); List<Proveedor> proveedor = dao.getAll(); Object[][] elementos = new Object[proveedor.size()][2]; for (int i = 0; i < proveedor.size(); i++) { Proveedor p = proveedor.get(i); elementos[i][0] = p.getId(); elementos[i][1] = p

I made a combobox but some of the elements are wider than the width of my box. So I tried to add a horizontal scrolpane and the only I could see is a scrolpane with a combobox inside! Certanly something I do wrong. So here is my code without the jscrolpane. issuerdocumentJComboBox=new JComboBox<>(issuermodel);//the compo box issuerdocumentJComboBox.setBounds(430, 120, 100, 30); searchDocumentesJPanel.add(issuerdocumentJComboBox); How can I add to the combobox a horizontal scrollpane? Thank you! It is possible!! Here's a little program I wrote to show my solution: import java.awt.Component;
