I wish to manually move widgets in Tkinter, now I have successfully done it,
but with odd results, I would like to move the widgets with a much smoother
manner, and better precision.
Any help is greatly appreciated.

here is snip of working code:
from Tkinter import *
class blah:
def MoveWindow(self , event):
self.root.updat e_idletasks()
self.f.place_co nfigure(x=event .x_root, y=event.y_root-20)
def __init__(self):
self.root = Tk()
self.root.title ("...")
self.root.resiz able(0,0)
self.root.geome try("%dx%d%+d%+ d"%(640, 480, 0, 0))
self.f = Frame(self.root , bd=1, relief=SUNKEN)
self.f.place(x= 0, y=0, width=200, height=200)
self.l = Label(self.f, bd=1, relief=RAISED, text="Test")
self.l.pack(fil l=X, padx=1, pady=1)
self.l.bind('<B 1-Motion>', self.MoveWindow )
self.f.bind('<B 1-Motion>', self.MoveWindow )
self.root.mainl oop()

event.x_root & event.y_root will give you the coordinates of the event in the
*screen*, which is apparently not what you want. The name "root" traditionally
used for Tkinter main windows is somewhat confusing here: the window called
"root" in tk/Tkinter methods is the screen, not your main window.
def __init__(self): self.root = Tk() self.root.title ("...") self.root.resiz able(0,0) self.root.geome try("%dx%d%+d%+ d"%(640, 480, 0, 0))
self.f = Frame(self.root , bd=1, relief=SUNKEN) self.f.place(x= 0, y=0, width=200, height=200)
self.l = Label(self.f, bd=1, relief=RAISED, text="Test") self.l.pack(fil l=X, padx=1, pady=1)
self.l.bind('<B 1-Motion>', self.MoveWindow ) self.f.bind('<B 1-Motion>', self.MoveWindow )
self.root.mainl oop()
x = blah()
Doing what you want is a bit more complicated than what you've already done: the
best way to use event.x_root and event.y_root here is relatively to a former
recorded position. What I'd do would be the following:
-----------------------------------------
from Tkinter import *
class blah:
def startMoveWindow (self, event):
## When the movement starts, record current root coordinates
self.__lastX, self.__lastY = event.x_root, event.y_root
def MoveWindow(self , event):
self.root.updat e_idletasks()
## Use root coordinates to compute offset for inside window coordinates
self.__winX += event.x_root - self.__lastX
self.__winY += event.y_root - self.__lastY
## Remember last coordinates
self.__lastX, self.__lastY = event.x_root, event.y_root
## Move inside window
self.f.place_co nfigure(x=self. __winX, y=self.__winY)
def __init__(self):
self.root = Tk()
self.root.title ("...")
self.root.resiz able(0,0)
self.root.geome try("%dx%d%+d%+ d"%(640, 480, 0, 0))
## Record coordinates for window to avoid asking them every time
self.__winX, self.__winY = 0, 0
self.f = Frame(self.root , bd=1, relief=SUNKEN)
self.f.place(x= self.__winX, y=self.__winY, width=200, height=200)
self.l = Label(self.f, bd=1, relief=RAISED, text="Test")
self.l.pack(fil l=X, padx=1, pady=1)
## When the button is pressed, make sure we get the first coordinates
self.l.bind('<B uttonPress-1>', self.startMoveW indow)
self.l.bind('<B 1-Motion>', self.MoveWindow )
self.f.bind('<B uttonPress-1>', self.startMoveW indow)
self.f.bind('<B 1-Motion>', self.MoveWindow )
self.root.mainl oop()
x = blah()
-----------------------------------------

I only want to display 5 or 10 at a time. Can this be accomplished by
putting everything in a Frame(), using width, height, grid_propagate(0)
, and a scrollbar? or do I have to grid 5 rows at a time? If the
latter, can I just grid over the previous 5 or do they have to be
explicitly removed...

Howdy all,
Python programmers looking for a built-in GUI toolkit are told two
things: one, Python already comes with a GUI toolkit, and two, it
looks equally ugly on all platforms. This is because the Tk widget
library, that Tkinter uses, defaults to looking like Motif, which
hasn't been the default widget set of *anything* for a long time.
The Tk folks are apparently getting their act together. Tile is a
"theming engine" for Tk with...
