I am trying not to use the navigation toolbar, instead I want to add these actions in the Mainwindow toolbar. Below is an example of the customization:
import sys
import matplotlib
matplotlib.use('Qt5Agg')
from PyQt5.QtWidgets import QToolBar, QMainWindow, QAction, qApp, QApplication
from PyQt5 import QtCore, QtGui, QtWidgets
from PyQt5.QtGui import QIcon
from matplotlib.backends.backend_qt5agg import FigureCanvasQTAgg, NavigationToolbar2QT as NavigationToolbar
from matplotlib.figure import Figure
class MplCanvas(FigureCanvasQTAgg):
def __init__(self, parent=None, width=5, height=4, dpi=100):
fig = Figure(figsize=(width, height), dpi=dpi)
self.axes = fig.add_subplot(111)
super(MplCanvas, self).__init__(fig)
class MainWindow(QtWidgets.QMainWindow):
def __init__(self, *args, **kwargs):
super(MainWindow, self).__init__(*args, **kwargs)
zoomact = QAction(QIcon('zoom.png'), 'zoom', self)
zoomact.setShortcut('Ctrl z')
zoomact.triggered.connect(self.zoom)
self.toolbar = self.addToolBar('zoom')
self.toolbar.addAction(zoomact)
self.sc = MplCanvas(self, width=5, height=4, dpi=100)
self.sc.axes.plot([0,1,2,3,4], [10,1,20,3,40])
#
toolbar = NavigationToolbar(self.sc, self)
"""Here I don't want to use the NavigationToolbar, but custom actions in the
toolbar. So I don't want to show the NavigationToolbar"""
"Is there any custom function in the Figure canvas"
layout = QtWidgets.QVBoxLayout()
layout.addWidget(toolbar)
layout.addWidget(self.sc)
# Create a placeholder widget to hold our toolbar and canvas.
widget = QtWidgets.QWidget()
widget.setLayout(layout)
self.setCentralWidget(widget)
self.show()
"Customize function for a specific figure"
def zoom(self):
"""here, I want to call the specific zoom function from NavigationToolbar
to apply to this specific FigureCanvas using lambda function"""
# My trial. I don't know, I cant figure it out :)
lambda sc: NavigationToolbar2QT.toolitems["zoom"](self.sc, self)
def home(self):
pass
def Editaxis(self):
pass
def configuresubplots(self):
pass
def save(self):
pass
def leftbuttonpans(self):
pass
def backtopreviousview(self):
pass
def forwardtonextview(self):
pass
app = QtWidgets.QApplication(sys.argv)
w = MainWindow()
app.exec_()
So,
- I want to hide the NavigationToolbar and not to use it
- Then, to create custom actions in the Mainwindow toolbar that can act on the figure in the canvas, such as zoom, edit axis.....etc.
CodePudding user response:
You have to pass None as parent of the NavigationToolbar2QT:
import sys
import matplotlib
matplotlib.use("Qt5Agg")
from PyQt5.QtWidgets import QAction, QApplication, QMainWindow, QVBoxLayout, QWidget
from PyQt5.QtGui import QIcon
from matplotlib.backends.backend_qt5agg import FigureCanvasQTAgg, NavigationToolbar2QT
from matplotlib.figure import Figure
class MplCanvas(FigureCanvasQTAgg):
def __init__(self, parent=None, width=5, height=4, dpi=100):
fig = Figure(figsize=(width, height), dpi=dpi)
self.axes = fig.add_subplot(111)
super(MplCanvas, self).__init__(fig)
class MainWindow(QMainWindow):
def __init__(self, *args, **kwargs):
super(MainWindow, self).__init__(*args, **kwargs)
print("Text: Name of method")
for text, _, _, callback in NavigationToolbar2QT.toolitems:
if isinstance(text, str):
print(f"{text}: {callback}")
self.sc = MplCanvas(self, width=5, height=4, dpi=100)
self.mpl_toolbar = NavigationToolbar2QT(self.sc, None)
zoomact = QAction(QIcon("zoom.png"), "zoom", self)
zoomact.setShortcut("Ctrl z")
zoomact.triggered.connect(self.mpl_toolbar.zoom)
self.toolbar = self.addToolBar("zoom")
self.toolbar.addAction(zoomact)
self.sc.axes.plot([0, 1, 2, 3, 4], [10, 1, 20, 3, 40])
widget = QWidget()
self.setCentralWidget(widget)
layout = QVBoxLayout(widget)
layout.addWidget(self.sc)
def main():
app = QApplication(sys.argv)
w = MainWindow()
w.show()
app.exec_()
if __name__ == "__main__":
main()
Another option is to remove the QActions from the NavigationToolbar2QT:
import sys
import matplotlib
matplotlib.use("Qt5Agg")
from PyQt5.QtWidgets import QAction, QApplication, QMainWindow, QVBoxLayout, QWidget
from PyQt5.QtGui import QIcon
from matplotlib.backends.backend_qt5agg import FigureCanvasQTAgg, NavigationToolbar2QT
from matplotlib.figure import Figure
class MplCanvas(FigureCanvasQTAgg):
def __init__(self, parent=None, width=5, height=4, dpi=100):
fig = Figure(figsize=(width, height), dpi=dpi)
self.axes = fig.add_subplot(111)
super(MplCanvas, self).__init__(fig)
class MainWindow(QMainWindow):
def __init__(self, *args, **kwargs):
super(MainWindow, self).__init__(*args, **kwargs)
print("Text: Name of method")
for text, _, _, callback in NavigationToolbar2QT.toolitems:
if isinstance(text, str):
print(f"{text}: {callback}")
self.sc = MplCanvas(self, width=5, height=4, dpi=100)
self.toolbar = NavigationToolbar2QT(self.sc, self)
self.addToolBar(self.toolbar)
self.toolbar.clear()
zoomact = QAction(QIcon("zoom.png"), "zoom", self)
zoomact.setShortcut("Ctrl z")
zoomact.triggered.connect(self.toolbar.zoom)
self.toolbar.addAction(zoomact)
self.sc.axes.plot([0, 1, 2, 3, 4], [10, 1, 20, 3, 40])
widget = QWidget()
self.setCentralWidget(widget)
layout = QVBoxLayout(widget)
layout.addWidget(self.sc)
def main():
app = QApplication(sys.argv)
w = MainWindow()
w.show()
app.exec_()
if __name__ == "__main__":
main()
