Hello @ all,
i am testing out a first Tkinter python program on different OS. On Raspbian ( Stretch ) i run this program under IDLE and IDLE3 and from Geany ( 1.29 ). The code is : ` #from Tkinter import * # Python 2 from tkinter import * # Python 3
# definition of function upper radio button pressed which creates a picture in the window. The picture is in file Rechteck_gelb_mit_Punkt_blau.gif # see definiton of blue_img on the bottom of this script def upper_radio_button_pressed(): canvas.create_image(20,20, anchor=NW, image=blue_img)
# definition of function upper radio button pressed which creates a picture in the window. The picture is in file Rechteck_gelb_mit_Punkt_rot.gif # see definiton of red_img on the bottom of this script def lower_radio_button_pressed(): canvas.create_image(20,20, anchor=NW, image=red_img)
# definition of class App which is handling the Quit and the hello Button class App: def __init__(self, master): frame = Frame(master) frame.pack() self.button = Button(frame, text="QUIT", fg="red", command=frame.quit) self.button.pack(side=LEFT)
self.slogan = Button(frame, text="Hello", command=self.write_slogan) self.slogan.pack(side=LEFT)
def write_slogan(self): # definition of function write slogan. The text is written in the command line box only if the button Hello is pressed. print ("Tkinter is easy to use!")
# Tkinter window definition root = Tk() root.title("First python Tkinter window")
# width x height + x_offset + y_offset: root.geometry("500x600+30+30")
# define red label inside the window with text "red Label" w = Label(root, text="Red Label", bg="red", fg="white")
# automatic managing of geometrie ( pack manager )of label w inside of the window # means x coordinate is done automatically and Y coordinate is given ( for x use padx =...) w.pack(fill=X,pady=10)
# integer variable definition v = IntVar()
entry1 = Entry(root) entry2 = Entry(root)
# definition of Label "Choose a programming language" Label(root, text="""Choose a programming language:""", justify = LEFT, padx = 20).pack()
# definition of pushable radiobuttons with text Phyton or Perl Radiobutton(root, text="Python", padx = 20, variable=v, value=1, command=upper_radio_button_pressed).pack(anchor=W) # call the function upper_radio_button pressed
Radiobutton(root, text="Perl", padx = 20, variable=v, value=2, command=lower_radio_button_pressed).pack(anchor=W)# call the function upper_radio_button pressed
# a canvas is a graphical object, here blue_img and red_img # define the dimensions of the pictures inside of the window and that it is shown inside of the window root
canvas_width = 200 canvas_height = 100 canvas = Canvas(root, width=canvas_width, height=canvas_height) canvas.pack()
#definition of picture blue_img blue_img = PhotoImage(file="/Users/holgerlech/Documents/85_Computer/Python/Quadrat_gelb_mit Smilie.PPM") #definition of picture red_img red_img = PhotoImage(file="/Users/holgerlech/Documents/85_Computer/Python/Rechteck_gelb_mit_Punkt_rot.gif")
# call of the class App with parameter root for the window app = App(root)
Label(root,text="Vorname:").pack() vorname = entry1.pack()
Label(root,text="Nachnahme:").pack() nachname = entry2.pack()
#start window loop root.mainloop()
print(vorname) print(nachname) ` In IDLE the Tk window was opened but in Geany only a Terminal window with "geany_run_script_93XQp0.sh" appears and that's it, nothing more happens. On Mac OS a script is started too, but then the Tk windows appears. Whats wrong here ?  
Thank You very much !
