I would like to dynamically add checkboxes to a tkinter grid and then have the user check some of them and afterwards see, which checkboxes were checked.
Here's the code:
top = tkinter.Tk()
var2 = tkinter.IntVar()
main()
top.mainloop()
# in main
for feat in feats:
counter += 1
tkinter.Checkbutton(top, text=str(merkmal) + " ist " +
str(label), command=lambda: testResult(),
variable=var2).grid(row=counter, sticky="W")
# callback
def testResult():
print(var2)
Two problems:
a) I need a vertical and horizontal scrollbar on my grid
I have looked at other posts and seen that I need to add a canvas and then add the scrollbar to the canvas but I havent gotten it to work. Here's my attempt:
w = tkinter.Canvas(top)
scrollbar = tkinter.Scrollbar(top, orient="vertical",command=w.yview)
scrollbar.grid(row=0,column=1,sticky='ns')
w.config(yscrollcommand=scrollbar.set, xscrollcommand=scrollbar.set)
w.grid(row=0,column=0,sticky='nsew')
and then addind the checkboxes to w instead of top. The vertical scrollbar shows, but I cant scroll.
b) When I check one of the boxes, all of them get checked. How can I make it so that each checkbox can be checked individually?
I am new to tkinter and really don't have to learn too much into it, just need this to work somehow.
Thanks for any help!
EDIT
canvas = tkinter.Canvas(top, bg='#FFFF12', width=300, height=900, scrollregion=(0, 0, 900, 900))
hbar = tkinter.Scrollbar(top, orient="horizontal")
hbar.pack(side="bottom", fill="x")
hbar.config(command=canvas.xview)
vbar = tkinter.Scrollbar(top, orient="vertical")
vbar.pack(side="right", fill="y")
vbar.config(command=canvas.yview)
canvas.config(xscrollcommand=hbar.set, yscrollcommand=vbar.set)
canvas.pack(side="left", expand=True, fill="both")
It shows the scrollbar, the vertical scrollbar moves a bit, but the content doesnt move. When I attach everything to a frame, then the scrollbar doesnt move either.
