[pyqtgraph] disable some functions of right-click menu

[Duan Yi]

How can I disable/customize the functions of the right-click menu in
pyqtgraph? Much appreciated.

Code example. I don't guarantee that copy-paste will work as It is only a
part of my whole code, but it should give you some tips and ideas.

import pyqtgraph as pg

class MyCustomPlotContextMenu(pg.ViewBox):
"""Subclass of ViewBox.
"""

def __init__(self parent=None):
"""Constructor of the QVizCustomPlotContextMenu

super(MyCustomPlotContextMenu, self).__init__(parent)

# Set original plot context menu
# Note: self.menu must not be None (this way works fine for plotWidgets,
# but not for GraphicsWindow)
self.menu = pg.ViewBoxMenu.ViewBoxMenu(self)

# Menu update property
self.menuUpdate = True

def getMenu(self, event=None):
"""Modify the menu. Called by the pyqtgraph.ViewBox raiseContextMenu()
routine.
Note: Overwriting the ViewBox.py getMenu() function.
"""

if self.menuUpdate is True:
# Modify contents of the original ViewBoxMenu
for action in self.menu.actions():
# Modify the original Mouse Mode
if "Mouse Mode" in action.text():
# Change action labels
for mouseAction in self.menu.leftMenu.actions():
if "3 button" in mouseAction.text():
mouseAction.setText("CustomLabel1")
elif "1 button" in mouseAction.text():
mouseAction.setText("CustomLabel2")

# Add custom contents to menu
self.addCustomToMenu()

# Set menu update to false
self.menuUpdate = False

return self.menu

def addCustomToMenu(self):
"""Add custom actions to the menu.
"""
self.menu.addSeparator()
# Autorange feature
self.actionAutoRange = QAction("Auto Range", self.menu)
self.actionAutoRange.triggered.connect(self.autoRange)
# - Add to main menu
self.menu.addAction(self.actionAutoRange)

# - Add to main menu
self.menu.addAction(self.actionConfigurePlot)

To set your custom contextMenu as default one, you have to set it as a
'viewBox' argument

Example:

myPlotWidget = pg.PlotWidget(parent, viewBox=MyCustomPlotContextMenu)
