So I hit the following problem: I want to initializate the Swing constructor with a controller instance from my App class. That is the place I init the repo and controller. When i want to pass to the swing Gui class, the controller parameter I realized it has its own main method.
Could you please check the code and tell me if this is the correct approach? 'Cause I'm uncertain, and i can't find a basic example from a TUI app to a GUI app. Thank you!
App.java
package app;
import repository.*;
import view.View_gui;
import controller.*;
public class App{
RepoInterface ri;
ControllerInterface c;
View_gui gui;
public App() {
ri = new Repo();
c = new Controller(ri);
gui = new View_gui(c);
}
public static void main(String[] args) {
App app = new App();
}
}

I am developing one java swing application for task remainder.Please find the below code for the same.But the problem is i am not able to maintain session here since i am using ScheduledExecutorService class which will help to trigger this Swing app one hour once.When triggering new one all changes has been made in previous session of app is gone.
Kindly help me on this and let me know how can i use session on my Swing application.
Example : If you run the below app yon can see two buttons when we click on button it will change color to "green" and status change to "Done" but when the application trigger after one minute all changes were erased launching as new one.

I have a problem when i add a jpanel to existing jpanel!
i want jlist at center loction and jbuttom in south location!
i can see the jlist, but the jbuttom won't show on!
I'm using Eclipse 3.0 version.
this is my code:

super();
setLayout(new BorderLayout());
setSize(450 ,400);
String animals_list[] = new String[AquaPanel.swims.size()];
LinkedList<Swimmable> ir = new LinkedList<Swimmable>(AquaPanel.swims);
for(int i=0;i<ir.size();i++)
{
animals_list[i]=(i+1+". "+ir.get(i).toString());
}
list = new JList<String>(animals_list );
list.setFont(new Font("Tahoma",Font.BOLD,15));
list.setSize(450, 300);
add(list,BorderLayout.CENTER);
Change = new JButton("Change Color");
Change.addActionListener(this);
add(Change,BorderLayout.CENTER);
repaint();
}
#Override
public void actionPerformed(ActionEvent e) {
}
}
please help!
You have a subtle bug. In the constructor of JPanelDecorator you have :
public JPanelDecorator()
{
//....
add(list,BorderLayout.CENTER);
//...
add(Change,BorderLayout.CENTER); // center again...
//...
}
But what you need is this:
public JPanelDecorator()
{
//....
add(list,BorderLayout.CENTER);
//...
add(Change,BorderLayout.SOUTH); // south
//...
}
I'm new to jung and i need help on how to learn. I searched a lot of places, but i haven't found a step by step guide. Im trying to create a gui that will add vertexes only if they selected the right menu, and entered a proper name.

I need to know how to label each circle based on the state name they enter. Also any tips for learning JUNG would help.
I have customized the JTable cell editor in order to allow enter data from JDialog frame. I have used an editable combobox for that, I have added an ActionListener for combobox to display The dialog.
I have got my JDialog visible, but I want to make it unmovable, so the user can't move it.
Here is my code so far,

public class ProduitCellEditor extends AbstractCellEditor implements TableCellEditor,ActionListener, SearchProduitEventListener {
private JComboBox combo;
private SearchProduitUi searchProduitUi;
private String value = "value";
public ProduitCellEditor() {
combo = new JComboBox();
combo.setEditable(true);
combo.setActionCommand("combo");
searchProduitUi = new SearchProduitUi();
searchProduitUi.setSearchProduitEventListener(this);
searchProduitUi.setSize(500,300);
searchProduitUi.setLocationRelativeTo(combo);
}
#Override
public Object getCellEditorValue() {
return value;
}
#Override
public Component getTableCellEditorComponent(JTable jtable, Object o, boolean bln, int i, int i1) {
return combo;
}
public void actionPerformed(ActionEvent event) {
Point comboPosition = combo.getLocationOnScreen();
searchProduitUi.setLocationRelativeTo(combo);
searchProduitUi.setLocation(comboPosition.x ,comboPosition.y + combo.getHeight());
searchProduitUi.setVisible(true);
}
#Override
public void searchDialogEventOccured(SearchProduitEvent ev) {
value = ev.getProduit().getDesignation();
fireEditingStopped();
}
}
JDialog#setUndecorated will remove the frame decorations, including the close/minimise/maximise controls and make it impossible for the user to move the window.
