hi, I have a question about how to use .grid_forget (in python/TK) I need to work on grid repeatly. everytime when a button is pressed, the rows of grid is different. such like, first time, it generate 10 rows of data. 2nd time, it maybe only 5 rows. so I need a way to RESET the grid data every time. how can I do it? by grid_forger()?, then would anyone can help on how to use grid_forget() the sample code as following:
#####begin of program############### from Tkinter import * def mygrid(text): ######## how to use grid_forget() to clean the grid??########### rows = [] count=int(text) for i in range(count): cols = [] for j in range(4): e = Entry(frame3, relief=RIDGE) e.grid(row=i, column=j, sticky=NSEW) e.insert(END, '%d.%d' % (i, j)) cols.append(e) rows.append(cols) root=Tk() frame1=Frame(root, width=150, height=100) frame1.pack() text=Entry(frame1) text.pack(side=LEFT) button=Button(frame1, text='generate grid', command=(lambda: mygrid(text.get()))) button.pack() frame2=Frame(root, width=150, height=100) frame2.pack() button2=Button(frame2, text='exit', command=root.quit) button2.pack() frame3=Frame(root, width=150, height=300) frame3.pack() root.mainloop() #####end of program############### -- http://mail.python.org/mailman/listinfo/python-list
