<p>Hello @ all,</p>
<p>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 :<br>
`<br>
#from Tkinter import * # Python 2<br>
from tkinter import * # Python 3</p>
<h1>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</h1>
<h1>see definiton of blue_img on the bottom of this script</h1>
<p>def upper_radio_button_pressed():<br>
canvas.create_image(20,20, anchor=NW, image=blue_img)</p>
<h1>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</h1>
<h1>see definiton of red_img on the bottom of this script</h1>
<p>def lower_radio_button_pressed():<br>
canvas.create_image(20,20, anchor=NW, image=red_img)</p>

<p>class App:<br>

command=frame.quit)<br>
self.button.pack(side=LEFT)</p>
<pre><code>self.slogan = Button(frame,
text="Hello",
command=self.write_slogan)
self.slogan.pack(side=LEFT)
</code></pre>
<p>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.<br>
print ("Tkinter is easy to use!")</p>

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 ?<br>
