First post here, so please be gentle! I have searched far and wide for an answer to my question, but have turned up nothing.
I am trying to learn and apply the MVC architecture to create a Java Swing application. I think I understood the separate roles of the model, view and the controller.
However, my application has a JMenuBar (File, Edit and so on...).
What I want to do is after clicking a menu item, a form to pop up (which gets delegated in to the controller from the DVSDesk class).
The difficulty I am having is how to display the form accepting the controller and model -- from what I have read, each JFrame needs it's own thread, which is where I get confused. As the invokeLater is in its own unique thread, I can not seem to pass model or controller in.
Apologies if this is a dumb question, but I have been doing a lot of searching around, and seem to be getting nowhere fast!
EDIT -- My real question -- Is the showImporterForm() the correct way of creating and showing the new form?
Below is the code for the main thread (DVSMain.java)
public static void main(String[] args) {
TopLevelController TLC;
TopLevelModel TLM;
java.awt.EventQueue.invokeLater(new Runnable() {
@Override
public void run() {
TopLevelModel TLM = new TopLevelModel();
TopLevelController TLC = new TopLevelController(TLM);
}
});
}
Below is the code for the controller (TopLevelController.java)
public class TopLevelController {
// Initialise model and view
TopLevelModel TLM;
DVSDesk TLV;
public TopLevelController(TopLevelModel model) {
// Get a reference to the view and model
TLM = model;
TLV = new DVSDesk(this,model);
TLV.setVisible(true);
}
public void showImporter() {
ImportForm importFm = new ImportForm(this,TLM);
importFm.setVisible(true);
}
/*public void showForm(final Form fm) {
// Show the form which has been passed in
java.awt.EventQueue.invokeLater(new Runnable() {
@Override
public void run() {
fm.show();
}
});
}*/
public void quit() {System.exit(0);};
}
And below is the code from DVSDesk.java (the menu based GUI)...
public class DVSDesk extends javax.swing.JFrame {
/**
* Creates new form DVSDesk
*/
TopLevelController TLC;
TopLevelModel TLM;
public DVSDesk(TopLevelController controller, TopLevelModel model) {
initComponents();
TLC = controller;
TLM = model;
}
