reference to the plugin's toolbar button

[kabirmaar]

i would like to make plugin with drop-down menu (self.popup_type = QToolButton.InstantPopup) and instead of textual (q)action i would like to add custom QWidget.

i have separated code which looks like this:

class Window(QtGui.QWidget):
    def __init__(self):
        QtGui.QWidget.__init__(self)
        layout = QtGui.QHBoxLayout(self)
        self.button = QtGui.QToolButton(self)
        self.button.setPopupMode(QtGui.QToolButton.InstantPopup)
        self.button.setMenu(QtGui.QMenu(self.button))
        self.textBox = QtGui.QTextBrowser(self)
        action = QtGui.QWidgetAction(self.button)
        action.setDefaultWidget(self.textBox)
        self.button.menu().addAction(action)
        layout.addWidget(self.button)

if __name__ == '__main__':

    import sys
    app = QtGui.QApplication(sys.argv)
    window = Window()
    window.resize(100, 60)
    window.show()
    sys.exit(app.exec_())

i can't find the reference to plugin's toolbar button in calibre which i would use as equivalent to self.button (as above).

in calibre plugin development i tried things like: self.qaction.parentWidget() and few others (but rather would avoid showing it )

no luck.

any idea how to do that?

See setup_tool_button() in gui2/bars.py

Though I'm not clear why you need a reference to the button. Simply add your QWidgetAction to the qactions menu as you would normally.

hm. i was looking for a toolbar button as a reference because QWidgetAction asks for parent when created. and in the example above that parent is button on which action should be added.

when i do this in InterfaceAction.genesis (having action_add_menu = True):

self.qaction.menu().addAction(QWidgetAction().setDefaultWidget(d))

where d is QDialog instance in main.py (canonical plugin example) nothing happens. my guess was that QWidgetAction(plugin_toolbar_button).setDefaultWid get(d) will solve that problem. i could be easily wrong...

Set the menu as the parent. And keep a python reference to the widget action to prevent it from being garbage collected.

thanx. works!

had to add QMenu(self.gui) to qaction and keep a python reference to the widget action...

d = MyPlugin(self.gui, self.qaction.icon(), do_user_config, self.qaction)
m = QMenu(self.gui)
self.qaction.setMenu(m)
a = QWidgetAction(m)
a.setDefaultWidget(d)
m.addAction(a)
