Framed

Hello list, The following little test program works as expected. But if you change the line marked "----- Here ----" so it reads: self.Frame2 = Pmw.ScrolledFrame(self) then it blows up on an error deep inside Tkinter when attempting to create the button mentioned on the following line. All I wanted to do was trade a Frame for a ScrolledFrame. I'm stumped as to why it blows up. Anybody out there know? Thanks Cam ps I realize that in this example Frame2 is redundant. I encountered the problem in a larger case. To generate the example shown below I stripped out pretty much everything that wasn't necessary to demonstrate the problem. - - - - - import Pmw from Tkinter import * class Test(Frame): def __init__(self,Master=None,**kw): apply(Frame.__init__,(self,Master),kw) self.Frame2 = Frame(self) #<---- HERE ---- self.Frame2.pack(side='left') self.Button1 = Button(self.Frame2) self.Button1.pack(side='top') Root = Tk() Pmw.initialise(Root) App = Test(Root) App.pack(expand='yes',fill='both') Root.geometry('640x480+10+10') Root.mainloop()

Iterate Scale widgets
by rkundu＠ouray.cudenver.edu June 30, 2006

June 30, 2006

The problem with the following program is I am not able to get values corresponding to each scale widgets. I tried initially storing the scale widget names in a list and then get the values but did not work. So, I borrowed the trace variable part of the script from some internet source. In the program below all the scale widgets created are having the same variable var, how do I change the variable names automatically or is there any other way to retrieve the values of scales? Any advice will be appreciated. Thank you, Reema from Tkinter import* import sys, Tkinter, types, copy root = Tk() i = 1 k = 5 var = Tkinter.DoubleVar() oldvalue = var.get() def callback(*args): global oldvalue #An exclamation point tells var that what follows is a Python statement, not a var command. if var.get() != oldvalue: oldvalue = var.get() print var.get() var.trace_variable("w", callback) while i<=k: j=1 var1 = var + i while j<=k: Scale(root, from_ = 0.0, to = 1.0, resolution = 0.1, variable = var, orient = 'horizontal').grid(row=i,column=j) j=j+1 i=i+1 root.mainloop()

Button Overrelief
by Michael Foord June 29, 2006

June 29, 2006

Hello all, I have some Tkinter buttons that display images. I would like to change these to 'active' images when the mouse is over the button. I see that the button widget can take an 'overrelief' argument in the constructor. What values can this take ? Also - can anyone provide an example of using the equivalent of a 'mouseover' event to change the image used by a button in Tkinter ? I'm afraid google has not helped me much here. Much Appreciated, Fuzzyman http://www.voidspace.org.uk/python/index.shtml

application busy problem
by Olivier Feys June 23, 2006

June 23, 2006

Hi, I'm using Tkinter to create an application which parses some huge text files (from 50kb to 120Mb). When the files are being parsed, I would like to forbid the user to do anything else and to show the application is busy(like an icon that turns over itself), because when he clicks on anything, the application fails.

Mouse wheel event for Canvas
by John McMonagle June 23, 2006

June 23, 2006

I tried binding mouse wheel events (<Button-4>, <Button-5>) to a Tkinter Canvas widget with the hope of using the event.delta value to subsequently scroll the Canvas. However, it seems that event.delta always returns 0. For example, from Tkinter import * r = Tk() c = Canvas(r, scrollregion=(0,0,500,500), height=200, width=200) s = Scrollbar(r, command=c.yview) c.pack(side=LEFT) s.pack(side=RIGHT, fill=Y) c.configure(yscrollcommand=s.set) c.create_rectangle(10,10,100,100) c.create_rectangle(10,200,100,300) def rollWheel(event): print event.delta c.bind('<Button-4>', rollWheel) c.bind('<Button-5>', rollWheel) c.focus_set() r.mainloop() Has anyone successfully managed to wheel scroll a Tkinter Canvas widget ?

creating widgets generically, with a loop?
by Mike Steiner June 22, 2006

June 22, 2006

Some background info: I have a Python/Tkinter script that displays a dialog with buttons, where each button launches a file for editing. Sort of like an HTML file in a browser, except with my script I can launch it using a particular program. I've been trying to figure out a way of storing widget information (name of each widget, x and y positions, and a command to execute when activated) in an array so I can generically create each widget instead of hard-coding all the information. For example, here's a snippet of what I currently use: ... Button(top, text="OO design info", command=self.launch_file23).grid(sticky="w",row=10,column=5) ... ... def launch_file23 ( self ): os.spawnl ( os.P_NOWAIT , "c:\\Program Files\\TextPad 4\\TextPad.exe" , "TextPad.exe" , "d:\\My Documents\\prog_oo_design.txt" ) ... If there was a way I could pass arguments to launch_file23 from the "command=" parameter, that would solve the problem nicely - I could store the info in an array, and then just loop to create the buttons. Any ideas? Michael Steiner MikeJaySteiner(a)yahoo.com (480) 720-8902 (cell) __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
