I am building a plugin in Qgis 3.24 Now, I want to access the "Toggle Editing" button from the Vector ToolBar using Python. Is it possible?

Edit - I want to access rotate feature, Scale feature, Delete part etc. from the toolbar using Python.

    Are you talking about the "Advanced Digitizing Toolbar" ?

    Please avoid asking new questions in comments, Instaed, use Ask Question button to ask additional questions. You are asking "how to access rotate etc. actions". "How to use rotate etc actions" is a different question. Nov 29, 2022 at 10:29

The first option is simply by using the startEditing() method of the QgsVectorLayer class.

layer = iface.activeLayer()

The second option, as was suggested by @J.Monticolo, is to apply the edit(). However, remember that it will also automatically call layer.commitChanges() on success.

layer = iface.activeLayer()
with edit(layer):
    # do something here

The third option is to penetrate the QApplication class, and try to find it's 'Digitizing Toolbar'-child.

all_widgets = QApplication.instance().allWidgets()
for widget in all_widgets:
    if widget.windowTitle() == 'Digitizing Toolbar':
        for action in widget.actions():
            if action.objectName() == 'mActionToggleEditing':

P.S. Thank you @KadirŞahbaz for a tip with trigger() method of the QAction class.

To get to the 'Rotate Feature(s)'-action from the "Advanced Digitizing Toolbar":

all_widgets = QApplication.instance().allWidgets()
for widget in all_widgets:
    if widget.windowTitle() == 'Advanced Digitizing Toolbar':
        for action in widget.actions():
            if action.objectName() == 'mActionRotateFeature':

Please, also consider @KadirŞahbaz's answer in this thread: Calling Rotate Feature tool from QGIS Python Console

    Hi Taras. setChecked doesn't activate buttons on Digitizing Toolbar, just sets the editing button checked. A better approach is to use action.trigger(). Nov 29, 2022 at 10:13

    I suggest asking it as a new question, instead of editing the old question\

A Qt answer :

edit_action = iface.mainWindow().findChild(QAction, "mActionToggleEditing")
