Geographic Information Systems Asked by Sean Ang on December 24, 2020
I was wondering if it is possible to add a toolbar with coordinate, scale magnifier, and rotation such as the one in QGIS Desktop to a custom PyQGIS canvas on a standalone application.
below is a simple code for map canvas in Main Window
from PyQt5 import QtCore, QtGui, QtWidgets
class Ui_MainWindow(object):
def setupUi(self, MainWindow):
MainWindow.setObjectName("MainWindow")
MainWindow.resize(800, 600)
self.centralwidget = QtWidgets.QWidget(MainWindow)
self.centralwidget.setObjectName("centralwidget")
self.gridLayout = QtWidgets.QGridLayout(self.centralwidget)
self.gridLayout.setObjectName("gridLayout")
self.widget = QgsMapCanvas(self.centralwidget)
self.widget.setObjectName("widget")
self.gridLayout.addWidget(self.widget, 0, 0, 1, 1)
MainWindow.setCentralWidget(self.centralwidget)
self.menubar = QtWidgets.QMenuBar(MainWindow)
self.menubar.setGeometry(QtCore.QRect(0, 0, 800, 26))
self.menubar.setObjectName("menubar")
MainWindow.setMenuBar(self.menubar)
self.statusbar = QtWidgets.QStatusBar(MainWindow)
self.statusbar.setObjectName("statusbar")
MainWindow.setStatusBar(self.statusbar)
self.retranslateUi(MainWindow)
QtCore.QMetaObject.connectSlotsByName(MainWindow)
def retranslateUi(self, MainWindow):
_translate = QtCore.QCoreApplication.translate
MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow"))
from qgis.gui import QgsMapCanvas
if __name__ == "__main__":
import sys
app = QtWidgets.QApplication(sys.argv)
MainWindow = QtWidgets.QMainWindow()
ui = Ui_MainWindow()
ui.setupUi(MainWindow)
MainWindow.show()
sys.exit(app.exec_())
I have no idea on how to execute this. I have searched google for PyQGIS Canvas Toolbar but it does not yield the results I want.
The end result would be something similar to this (ignore the layer on the canvas)
Wondering if anyone could point me in the right direction. Thanks!
