Sharing Actions between GUI Components

Question

Hi,
i have an MyPanels (JPanels) as tabs in JTabbedPane.
Each of MyPanels instances has own Actions (save, copy, paste, cut).
I want to put this actions in the toolbar of a JFrame.
The way i do it so far, is creating "dummy" Actions for a toolbar, and setting them each time the selected tab changes. I never use the "dummy" Actios, i just need them in toolbar, even when no tab selected ...
The first problem is i have to reset the actions for components each time as well (because the buttons configure from actions, don't use them. ..)
Is there any other solution for it?
I put all actions of MyPanel to an extra ActionMap, and get it to the parent frame.
I don't think it is the best solution ...
And i create actoins in Jframe, which i never use really ...
For now i have following solution in my JFrame class:
jTabbedPane.addChangeListener(new ChangeListener() {
            public void stateChanged(ChangeEvent e) {
               m_currentPane = getCurrentMyPane();
               updateTabsActions();
private void updateTabsActions(){
      if(m_currentPane!= null){        
            ActionMap actions = m_currentPane.getActions();
            saveFile_action = actions.get(saveFile_action.getValue(Action.NAME));
            jButton_Toolbar_SaveFile.setAction(saveFile_action);
            jMenuItem_FileSave.setAction(saveFile_action);
            copy_action = actions.get(copy_action.getValue(Action.NAME));
            jButton_Toolbar_Copy.setAction(copy_action);
            jMenuItem_EditCopy.setAction(copy_action);
        else{
            saveFile_action.setEnabled(false);
            copy_action.setEnabled(false);
}Has anybody a good solution to general share actions beteween components?
Thx for any answers, ideas, codes

Answer 1

Why dont you try interfacing?
make each panel ot tabbed pannel implemet this interface
public interface MyActions{
    public void save();
    public void cut();
}Then when the save button is pressed, the action should be :
JButton save=new JButton("Save");
save.addActionListener(new ActionListener(ActionEvent e){
              getCurrentOrSelectedPanel().getMyActions().save();//
               // I dont remmeber how to swap between panels, but I think you got the idea!!
                //you dont need to change the actions after that!!
//Do the same for every button. :
getCurrentOrSelectedPanel().getMyActions().cut();//
getCurrentOrSelectedPanel().getMyActions().paste();//This way the save Button for example, will have different save operations depending on the current displayed panel.
