My little brother is just getting into programming, and for his Science Fair project, he’s doing a simulation of a flock of birds in the sky. He’s gotten most of his code written, and it works nicely, but the birds need to move every moment.
I have a small GUI test with a “Start” button and a Progress bar. The desired behavior is:
I’m writing a program with Python’s tkinter library.
I’m having issues with redrawing the figure here. I allow the user to specify the units in the time scale (x-axis) and then I recalculate and call this function plots(). I want the plot to simply update, not append another plot to the figure.
Filter Log Recordset by 2 and DEBUG
I want to make 5 buttons in a loop, and for each buttons bind a commend to print the index. In the following solution it always prints the same index.
I see and saw a lot of questions for tkinter that quite often asks not about errors in their code, but asks how do I organize my GUI. So I would like to have an answer that focus on that and help beginners to orientate them a little bit.
In the given example from this post, it was mentioned that if default bindtags are used then event value will not be visible inside definition (there will be lag by one).
I have been searching a lot and I still don’t know how you access variables from different classes in python. In this case I want to access the variable self.v from PageOne class to PageTwo class.
My objective is to add a vertical scroll bar to a frame which has several labels in it. The scroll bar should automatically enabled as soon as the labels inside the frame exceed the height of the frame. After searching through, I found this useful post. Based on that post I understand that in order to achieve what i want, (correct me if I am wrong, I am a beginner) I have to create a Frame first, then create a Canvas inside that frame and stick the scroll bar to that frame as well. After that, create another frame and put it inside the canvas as a window object. So, I finally come up with this:
