I am currently building a GUI using pyqt, does anyone know how I can align a qtexttable and a qimage next to each other in a qtextdocument. They are presently stacked but I would prefer if they can be inserted side by side. Please find below my code. The table and image are both embedded in the qtextdocument.

Additional Info: I used Qt Designer to create Widget.ui file and converted to Widget.py. My machine host is windows and I am running Ubuntu 18.04 in virtualbox. My python version is 2.7. I would really appreciate any help (I spent more than a day on this problem) and can provide any missing info. Thanks
and below is my ui converted to py:

I tried to integrate the code of this Radar graphic (see link) into a GUI containing a widget.
Instead of plotting x and y into the widget, I would like to plot a radar graphic but I can't solve this problem.
The idea is to replace this piece of code:
x = [2000,2001,2002,2003,2004]
y = [10,20,30,40,50]
self.axes.plot(x, y
With the code from the link above.

Thank you
the radar type graph is a graph with polar projection, so when creating the axes you must activate that property.
self.axes = fig.add_subplot(111, projection="polar")
When using the plot function, the first parameter is the angle in radians, and the second the length of the radius.
class Graph_init(FigureCanvas):
def __init__(self, parent=None):
fig = Figure()
self.axes = fig.add_subplot(111, projection="polar")
self.compute_initial_figure()
FigureCanvas.__init__(self, fig)
self.setParent(parent)
FigureCanvas.setSizePolicy(self, QSizePolicy.Expanding, QSizePolicy.Expanding)
FigureCanvas.updateGeometry(self)
class Graph_populate(Graph_init):
def compute_initial_figure(self):
import math
r =[10, 20, 30, 40, 50]
theta = [0, 50, 90, 120, 180]
angles = [angle*math.pi/180 for angle in theta]
self.axes.plot(angles, r)
I use pyqtgraph to plot in PyQt5 GUI. I can plot in a pop-up window, but I am trying embed the graph in the graphicsView area.
Here is how I can do a simple plot in a new window:
self.pushButton.clicked.connect(self.btn_clk)
MainWindow.show()
def btn_clk(self):
L = [1,2,3,4,5]
pg.plot(L)
I tried to use this line to embed the plot, but it doesn't work:
self.pushButton.clicked.connect(self.btn_clk)
MainWindow.show()
def btn_clk(self):
L = [1,2,3,4,5]
self.graphicsView.plot(L)
Here is the full code:
import pyqtgraph as pg
from PyQt5 import QtCore, QtGui, QtWidgets

Pg.plot returns an instance of the pg.graphicsWindows.PlotWindow class, and this class inherits from QGraphicsView, ie pg.graphicsWindows.PlotWindow is used to plot but QGraphicsView is not. If you want to embed a plot within the Widget you must use the class pg.PlotWidget(), you must change:
self.graphicsView = QtWidgets.QGraphicsView(self.centralwidget)
to:
self.graphicsView = pg.PlotWidget(self.centralwidget)
and:
def btn_clk(self):
L = [1,2,3,4,5]
self.graphicsView.plot(L)#this line doesn't work
Output:
i designed in PyQt-Designer a surface and converted it to a .py
No I´m trying to link a function to a menubar-(button). There is something like open, save, close....
I have tried a lot, but unsuccessfully, i hope you can help me to connect a simple function to the open-button in the menu bar.
for example a function that is linked to the menubar
menubar->open->function(open_path):
def open_path():
root= Tk()
Pfad=askdirectory()
root.destroy
Thank you for your help!
Here is the Code:

First of all I recommend you read the docs, it recommends not to modify the class generated by Qt Designer, but you must create another class that inherited from a widget and use the class provided by Qt Designer as an interface.
On the other hand it is not necessary to use tkinter, Qt provides widgets to obtain directory paths like QFileDialog.
And finally you have to use the triggered signal of self.actionOpen.
Considering the above the solution is:
from PyQt5 import QtCore, QtGui, QtWidgets
class Ui_MainWindow(object):
def setupUi(self, MainWindow):
# ...
def retranslateUi(self, MainWindow):
# ...
class MainWindow(QtWidgets.QMainWindow, Ui_MainWindow):
def __init__(self, parent=None):
super(MainWindow, self).__init__(parent)
self.setupUi(self)
self.actionOpen.triggered.connect(self.open_file)
#QtCore.pyqtSlot()
def open_file(self):
fdirectory = QtWidgets.QFileDialog.getExistingDirectory(self, "Open Directory")
if fdirectory:
print(fdirectory)
if __name__ == "__main__":
import sys
app = QtWidgets.QApplication(sys.argv)
w = MainWindow()
w.show()
sys.exit(app.exec_())
