QWidgetAction: A QTreeWidget in a QMenu

[chezifresh]

I'm trying to get a QTreeWidget into the submenu of a context menu. (This is to allow users to selected alternate versions of the thing they're right clicking on).

I created a custom QWidgetAction but for some reason the widget doesnt disappear when the action is triggered. Any ideas on why this isnt working??

class QdVersionListAction(QtGui.QWidgetAction):
    def __init__(self, path, parent=None):
        QtGui.QWidgetAction.__init__(self, parent)
        self.path = path
        self.new_version = ""
 
    def createWidget(self, parent):
        widget = QdVersionTree(self.path, parent)
        widget.setMinimumSize(450, 100)
        self.connect(widget, SIGNAL("versionSelected(QString)"), self.versionAccepted)
        self.activate(QtGui.QAction.Trigger)
        return widget
 
    def versionAccepted(self, path):
        self.new_version = path
        # this works, the triggered signal is emitted and all
        self.activate(QtGui.QAction.Trigger)
 
        # What else can I do here????
        self.emit(SIGNAL("changed()"))
        self.toggle()
        print 'version accepted', path
 
class QdVersionTree(QtGui.QTreeWidget):
    def __init__(self, path, parent=None):
        QtGui.QTreeWidget.__init__(self, parent)
        self.setAllColumnsShowFocus(True)
 
        attributes = ["version", "name", "creator", "description"]
        self.setHeaderLabels(atributes)
        self.setFrameStyle(QtGui.QFrame.NoFrame)
 
        versions = [1, 2, 3, 4, 5, 6]
        for version in versions:
            columns = []
            for attribute in attributes:
                columns.append(attribute)
 
            item = QdVersionTreeItem(self, columns)
            self.addTopLevelItem(item)
 
        self.connect(self, SIGNAL("itemActivated(QTreeWidgetItem *, int)"),
                     self.itemActivated)
 
    def itemActivated(self, item, column):
        self.emit(SIGNAL("versionSelected(QString)"), "foo")

class QdVersionListAction(QtGui.QWidgetAction):
    def __init__(self, path, parent=None):
        QtGui.QWidgetAction.__init__(self, parent)
        self.path = path
        self.new_version = ""

    def createWidget(self, parent):
        widget = QdVersionTree(self.path, parent)
        widget.setMinimumSize(450, 100)
        self.connect(widget, SIGNAL("versionSelected(QString)"), self.versionAccepted)
        self.activate(QtGui.QAction.Trigger)
        return widget

    def versionAccepted(self, path):
        self.new_version = path
        # this works, the triggered signal is emitted and all
        self.activate(QtGui.QAction.Trigger)

        # What else can I do here????
        self.emit(SIGNAL("changed()"))
        self.toggle()
        print 'version accepted', path

class QdVersionTree(QtGui.QTreeWidget):
    def __init__(self, path, parent=None):
        QtGui.QTreeWidget.__init__(self, parent)
        self.setAllColumnsShowFocus(True)

        attributes = ["version", "name", "creator", "description"]
        self.setHeaderLabels(atributes)
        self.setFrameStyle(QtGui.QFrame.NoFrame)

        versions = [1, 2, 3, 4, 5, 6]
        for version in versions:
            columns = []
            for attribute in attributes:
                columns.append(attribute)

            item = QdVersionTreeItem(self, columns)
            self.addTopLevelItem(item)

        self.connect(self, SIGNAL("itemActivated(QTreeWidgetItem *, int)"),
                     self.itemActivated)

    def itemActivated(self, item, column):
        self.emit(SIGNAL("versionSelected(QString)"), "foo")

void MyButton::mouseReleaseEvent(QMouseEvent *event)
{
	// this one triggers the action and untoggles the button
	QToolButton::mouseReleaseEvent(event);
	// this one forwards the event to the parent
	QWidget::mouseReleaseEvent(event);
}

void MyButton::mouseReleaseEvent(QMouseEvent *event)
{
	// this one triggers the action and untoggles the button
	QToolButton::mouseReleaseEvent(event);
	// this one forwards the event to the parent
	QWidget::mouseReleaseEvent(event);
}
