ActionListener for JToolBar components

[LianaN]

Hi!

I would like to add ActionListener to buttons stored in JToolBar. However, if I'm using the code bellow, then I could add only MouseListener ("addActionListener" doesn't work). So, is it possible to somehow add ActionListener? Thanks a lot!

        JToolBar toolBarUpdateDocs = new BrowserToolBar();
        toolBarUpdateDocs.setFloatable(false);   
toolBarUpdateDocs.getComponent(i).addActionListener(new java.awt.event.ActionListener() {
                    public void actionPerformed(java.awt.event.ActionEvent evt) {
                        System.out.println("Ok");
                    }
                  });
...

 private class BrowserToolBar extends JToolBar {
        private BrowserToolBar() {
                String[] imageFiles =
                  { "add.png", "del.png", "search.png" };
                String[] toolbarLabels =
                  { "Add", "Delete", "Find" };
                Insets margins = new Insets(0, 0, 0, 0);
                for(int i=0; i<toolbarLabels.length; i++) {
                  ToolBarButton but = new ToolBarButton("src/icons/" + imageFiles[i]);
                  but.setToolTipText(toolbarLabels[i]);
                  but.setMargin(margins);
                  add(but);
            }
        }
    }

I don't know what a ToolBarButton is but you should add an ActionListener to such a button; better make those buttons member variables (or keep them in another way) so you can add those listeners to them.

This is the ToolBarButton class:

    private class ToolBarButton extends JButton {
          private final Insets margins = new Insets(0, 0, 0, 0);

          private ToolBarButton(Icon icon) {
            super(icon);
            setMargin(margins);
            setVerticalTextPosition(BOTTOM);
            setHorizontalTextPosition(CENTER);
          }

          private ToolBarButton(String imageFile) {
            this(new ImageIcon(imageFile));
          }

          private ToolBarButton(String imageFile, String text) {
            this(new ImageIcon(imageFile));
            setText(text);
          }
    }

As I understand you've proposed to do the following:

    private class BrowserToolBar extends JToolBar {
        private BrowserToolBar() {
                String[] imageFiles =
                  { "add.png", "del.png", "search.png" };
                String[] toolbarLabels =
                  { "Add", "Delete", "Find" };
                Insets margins = new Insets(0, 0, 0, 0);
                for(int i=0; i<toolbarLabels.length; i++) {
                  ToolBarButton but = new ToolBarButton("src/icons/" + imageFiles[i]);
                  but.setToolTipText(toolbarLabels[i]);
                  but.setMargin(margins);
// ADD ACTION LISTENER TO "BUT"
                  add(but);
            }
        }
    }

However, the problem is that I would like to add ActionListener outside of the class BrowserToolBar:

JToolBar toolBarUpdateDocs = new BrowserToolBar();
        toolBarUpdateDocs.setFloatable(false); 
// ADD ACTION LISTENER TO the button of "toolBarUpdateDocs"

Is it possible?

Sure, your BrowserToolBar should be able to make those buttons available to the outside world so that outside world can add an ActionListener to the button(s).

Ok, thanks. I've solved this problem in the following way:

    private class BrowserToolBar extends JToolBar {
        private BrowserToolBar(String[] imageFiles, String[] toolbarLabels) {
                Insets margins = new Insets(0, 0, 0, 0);
                for(int i=0; i<toolbarLabels.length; i++) {
                  ImageIcon ic = new ImageIcon("src/icons/" + imageFiles[i]);
                  JButton but = new JButton(ic);
                  but.setToolTipText(toolbarLabels[i]);
                  but.setMargin(margins);
                  add(but);
            }
        }

        private JButton getButton(int i) {
            return (JButton) this.getComponent(i);
        }
    }

...

toolBarUpdateUsers.getButton(0).addActionListener...

Well done; but now you have to know the index of the button you want to retrieve (it doesn't matter much here).

Isn't this the same as "Make final" problem ?
