Use Button as renderer for list

问题

I would like to use a more complex renderer consisting of several components for a list (more precisely something like this (a textfieldinput with some buttons arranged in a panel). However when I try to use a button in a list it seems to ignore clicks.

Minimal example

from javax.swing import DefaultListCellRenderer
from javax.swing import DefaultListSelectionModel
from javax.swing import JButton
from javax.swing import JLabel
from javax.swing import JPanel
from javax.swing import JList
from javax.swing import JFrame


def printer():
    print "pressed the button"

class cellRenderer(DefaultListCellRenderer):



    def getListCellRendererComponent(self, theList, value, index, selected, hasFocus):
        renderer = DefaultListCellRenderer.getListCellRendererComponent(self, theList, value, index, selected, hasFocus)

        if selected:
            pan = JPanel()
            pan.add(JLabel('beer'))
            pan.add(JButton('get one', actionPerformed=printer))
            renderer = pan

        return renderer

panel = JFrame('example', size=(200,200))

configurations = JList([1,2,3,4],
                       cellRenderer = cellRenderer(),
                       selectionMode = DefaultListSelectionModel.SINGLE_SELECTION )

panel.add(configurations)
panel.visible = True

edit:added minimal example as suggested. Updated question since original problem was solved during minimal example creation

回答1:

A renderer alone is not sufficient; you also need an editor, which is not part of the JList API. As an alternative, use a JTable with a custom renderer and editor. JRadioAsRendererEditor is an example that adds a StatusPanel containing radio buttons. Of course, you can also use a multi-column table, too.
