I'm trying to use Tkinter Canvas
(self._canvas
) to create window using create_window
function. The window field for that function is a Tkinter Frame
(self._tableFrame
). Can someone please help me out on how to make self._tableFrame
to expand to size of self._canvas
automatically (Even after the window size changed by user)?
Code:
from Tkinter import Scrollbar as tkScrollBar
from Tkinter import Frame as tkFrame
from Tkinter import Canvas as tkCanvas
from Tkinter import Entry as tkEntry
from Tkinter import StringVar as tkStringVar
from Tkinter import Tk, HORIZONTAL, N, S, E, W, RIGHT, LEFT, BOTTOM, X, Y, BOTH
from Tkinter import TOP
class Widget(tkFrame):
def __init__(self, master=None):
tkFrame.__init__(self, master)
self._str = tkStringVar()
self._widget = tkEntry(self)
self._widget.config(textvariable=self._str, borderwidth=1, width=0)
self._widget.pack(expand=True, fill=X)
def settext(self, str_):
self._str.set(str_)
def gettext(self):
return self._str.get()
class Application(tkFrame):
def __init__(self, rows, cols, master=None):
tkFrame.__init__(self, master)
yScroll = tkScrollBar(self)
xScroll = tkScrollBar(self, orient=HORIZONTAL)
self._canvas = tkCanvas(self,
yscrollcommand=yScroll.set, xscrollcommand=xScroll.set)
yScroll.config(command=self._canvas.yview)
xScroll.config(command=self._canvas.xview)
self._table = [[0 for x in range(rows)] for x in range(cols)]
self._tableFrame = tkFrame(self._canvas)
for col in range(cols):
self._tableFrame.grid_columnconfigure(col, weight=1)
for row in range(rows):
self._table[row][col] = Widget(master=self._tableFrame)
self._table[row][col].settext("(%d, %d)" % (row, col))
self._table[row][col].grid(row=row, column=col, sticky=E+W)
# For debugging
self._canvas.config(background="blue")
self._tableFrame.config(background="red")
yScroll.pack(side=RIGHT, fill=Y)
xScroll.pack(side=BOTTOM, fill=X)
self._canvas.create_window(0, 0, window=self._tableFrame, anchor=N+W)
self._canvas.pack(side=LEFT, fill=BOTH, expand=True)
tkRoot = Tk()
# Application Size and Center the Application
appSize = (800, 600)
w = tkRoot.winfo_screenwidth()
h = tkRoot.winfo_screenheight()
x = w / 2 - appSize[0] / 2
y = h / 2 - appSize[1] / 2
tkRoot.geometry("%dx%d+%d+%d" % (appSize + (x, y)))
tkRoot.update_idletasks() # Force geometry update
app = Application(5, 5, master=tkRoot)
app.pack(side=TOP, fill=BOTH, expand=True)
tkRoot.mainloop()
