JLabel - get parent panel?

Question

Is it possible to get the name of the panel that a JLabel is added to? I added some JLabels to different JPanels, and I want to call different mouse events according to whic

Answer 1

The simplest way to do this:

//label1 and label2 are JLabel's
//panel1 and panel2 are JPanel's
doActionsForLabel(label1);
doActionsForLabel(label2);

public void doActionsForLabel(JLabel label)
{
    if (label.getParent() == panel1)
    {
        //do action #1
    }
    else if (label.getParent() == panel2)
    {
        //do action #2
    }
}

The above code assumes that the labels are direct children of the JPanels. However, this may not always be the case, sometimes they are great-grandchildren or great-great-grandchildren of the panel. If this is the case, you'll have do some slightly more complex operations to traverse the parent hierarchy.

public void doActionsForLabel(JLabel label)
{
    boolean flag = true;
    Component parent = label;
    while (flag)
    {
        parent = parent.getParent();
        if ((parent != null) && (parent instanceof JPanel))
        {            
            if (label.getParent() == panel1)
            {
                //do action #1
            }
            else if (label.getParent() == panel2)
            {
                //do action #2
            }            
        }
        else
        {
            flag = false;
        }
    }
}

As Gordon has suggested, if you don't want to test for equality of the components, you can test for equality of the components' properties:

Instead of label.getParent() == panel1, do this or similar instead: label.getParent().getName().equals("panel_1_name").
