[Geany-Users] Geany on Raspberry Pi... can't see Tkinter window

[Eric Stephan]

Hi -- thanks for that info!

-- I'm embarrassed to say that since I don't usually put longish scripts into the command line, I'm not sure how to get the many individual commands (with its odd bind commands etc) into just the command line.  merely pasting it gives "SyntaxError: multiple statements found while compiling a single statement"

-- BUT anyway, I think the basic question would then be, if I wanted to write a python app that used TKinter windows like that, how would I do it so that Geany would show the results?  TKinter is a quite commonly used component...

-- BTW, that script worked OK to show the TKinter output in both IDLE and Thonny IDEs

I'm guessing it's some not-too-complex little configuration or tweak somewhere...

thx 
Eric
