Access actions of ToolbarMenu/PanelMenu using PyQGIS

Question

For a Python plugin I need to remove/disable some UI elements so that they can't be accessed by the user. Thus, I removed the respective actions, toolbars and menus from the interface.

However, in order to prevent the user from turning back on the disabled elements, their corresponding menu entries also have to be removed. Unfortunately, I didn't find a way to access the viewmenu's entries "Toolbars" and "Panels" (which contain the desired actions). They are not returned when calling the viewmenu's children() method. Likewise, the findChild()/findChildren() methods do not return anything helpful either.

I already had a look on the QGIS git repository and it seems that the desired menus and actions are not added to the viewmenu as its child elements. They seem to do not have any parent element at all..

So does anybody know how I can access the "Panels" and "Toolbars" menus from out my plugin code?

Answer 1

Try using the following:

# statement for PyQt4
from PyQt4.QtGui import QDockWidget, QMenu, QToolBar
# Replace with the following line if QGIS 3
# from qgis.PyQt.QtWidgets import QDockWidget, QMenu, QToolBar

main_window = iface.mainWindow()

# To get "Panels" (in fact, we echoed their title)
print([i.windowTitle() for i in main_window.findChildren(QDockWidget)])
# To get "Toolbars" (in fact, we echoed their title)
print([i.windowTitle() for i in main_window.findChildren(QToolBar)])
# If quickosm plugin installed, remove it from the toolbar with
if len([i for i in main_window.findChildren(QToolBar) if i.windowTitle() == u'QuickOSM']) > 0:
    main_window.removeToolBar([i for i in main_window.findChildren(QToolBar) if i.windowTitle() == u'QuickOSM'][0])

# To get menus named "Panels" and "Toolbars"
print([i.title() for i in main_window.findChildren(QMenu) if i.title() in ['Panels', 'Toolbars']])

I now found a solution to my problem, although it's not the most elegant one. I got access to the elements by calling the actions() method of the view menu:

vm = iface.viewMenu()
panels = [i for i in vm.actions() if i.title() == 'Panels'][0]
toolbars = [i for i in vm.actions() if i.title() == 'Toolbars'][0]

Unfortunately the plugin will be used in multiple languages, so that the solution is not as generic as it should be. However, this should do it for the moment. Thanks for your answers!
