java - Define listModel on button press -


Then I'm creating a program that has this part of the code 

  last listModel Listmodel = new DefaultListModel (); Jebton BTN Brucerer = new pocket ("bus"); Btnbuscar.addActionListener {new actionalist} {public zero action action (action event e) {listModel = MySQL (select "* colosus WHERE id = '" + searchField.getText () + "' or '% name' "+ SearchField.getText () +"% 'or'% "like the keyword + searchField.getText () +"% '"," SELECT ");}}); Btnbuscular Setbound (336, 11, 89, 23); SearchPanel.add (btnBuscar); JScrollPane scrollPane = new JScrollPane (); ScrollPane.setBounds (10, 44, 316, 185); SearchPanel.add (Scrollpane); Gelist list = new jellist (list model); ScrollPane.setViewportView (list);

As you can see that I'm making a ListModel variable and then want to use it on the button press. MySQL function gives a list model.

Then I want to make a list and want to give it the element inside the list. What's wrong with this code?

In addition to SQL queries, you can final variable. You should make listModel a field (the example variable) instead of the last local variable so that your appnalist and can change it.

Instead of 

  public class YourClassName {public? YourMethodName () {last listModel listModel = new DefaultListMode (); Jebton BTN Brucerer = new pocket ("bus"); ...

You will write 

  Public category YourClassName {Private listModel listModel = New DefaultListModel (); public ? YourMethodName () {JButton btnBuscar = ...

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
