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()

Re: [Tkinter-discuss] writing a function to create button
by Ilknur Ozturk June 20, 2006

Hi Michael, Actually my aim is a little bit different. I put one of the buttons in my code; button_name = "menu" self.menu = Button(self.mycontainer, command=lambda arg1=button_name: self.writecommand(arg1) ) self.menu.configure(text="menu") self.menu.grid(row=2, column=0) ch = "<m>" self.menu.bind(ch, lambda event, arg1=button_name: self.writecommand(arg1) ) This part repeatedly occurs in my code for different buttons, but those buttons placed in a different frames (not each in one, group by group) For each button, button_name, configuration and geometry are changing. It can be divided 2 or more functions if it can be achieved in any way.

Re: [Tkinter-discuss] Scroll a table, but not the first two rows?

Scroll a table, but not the first two rows?
by Chris Niekel June 1, 2006

June 1, 2006

Hi, I'm trying to build a window that has a table with multiple columns. I'm using Pmw.ScrolledFrame now, creating the table with the .grid(row=N,column=N). This works quite good, but when more rows appear than fit in the window, the header of the column scrolls off. Is it possible to have the headers above the columns not scroll, but scroll the data below it? The columns and their header should be aligned properly. Thanks, Chris Niekel

calling toplevel creating function
by Ilknur Ozturk May 30, 2006

May 30, 2006

Hi all, I have a problem with toplevel window. It is created within a function and I am calling that function by button press. I have created 4 buttons that call same toplevel creating function. For the first call, there is no problem. The toplevel window is created and get the arguments. But the other call for that function results with an error message like; "Toplevel instance has no __call__ method" I could not solve what is the problem with it? What should I do to solve the problem?

Re: [Tkinter-discuss] calling function by keypress
by mkiever＠web.de May 16, 2006

May 16, 2006

Hello Ilknur, you need focus to get key events. So normally you set focus for the parent of all buttons (or the toplevel widget) and also bind the command to that widget. So: self.focus_set () self.bind ( '<KeyPress>', self.assignkey ) in the __init__ of your class should work. (your class needs to be a subclass of some widget, for example Frame) Hope this helps, Matthias Kievernagel Software-Development mkiever/at/web/dot/de

calling function by keypress
by Ilknur Ozturk May 15, 2006

May 15, 2006

Hi all, I am trying to call my function by keypress. Some specific keys will be assigned to some buttons. All widgets are created in a class. I wrote the code as below: functionalkeys=("Left", "F1",...) def assignkey(self, event): if event.keysym not in self.functionalkeys: return self.callcommand(event.keysym) def callcommand(self, arg1): if arg1=="Left": self.writecommand('left') if arg1=="F1": self.writecommand('menu') .......... else: return and bind assignkey() to my buttons, self.menu=Button(...) self.menu.bind("<KeyPress>", self.assignkey) this is working if I focused on the button, otherwise no action. I also bind keypress event to my main frame, but it is also not working. I am new for learning tk and most probably I am doing some basic thing wrong but I could not find it:-( Is there anyone to tell me how can I call the function without focusing the related button?

Radio Buttons
by Peter Lacroix May 11, 2006

May 11, 2006

Hi all, Let's say you had the following class below (MakeChoice) that was used to cast a vote. When the program is running, eventually the user will confirm choices made through some sort of "SUBMIT" button. When that button is clicked, we want the selected value (on a few sets of radio buttons) to be written to a file. What is the container of the currently selected value and how does one have that value be written to a file when a button is clicked? I hope my question is clear. Thanks! --------------------- class MakeChoice(Frame): def __init__(self, master): Frame.__init__(self, master) self.grid() self.create_widgets() def create_widgets(self): # Creates a string variable to bind the five radio buttons together self.current_selection = StringVar() # Choice 1 self.choice1 = Radiobutton( self ) self.choice1["text"] = "Queen Elizabeth" self.choice1["variable"] = self.current_selection, self.choice1["value"] = "Queen Elizabeth", self.choice1["command"] = self.set_text self.choice1.grid( row = 2, column = 0, sticky = W ) # Choice 2 self.choice2 = Radiobutton( self ) self.choice2["text"] = "Madonna" self.choice2["variable"] = self.current_selection, self.choice2["value"] = "Madonna", self.choice2["command"] = self.set_text self.choice2.grid( row = 3, column = 0, sticky = W ) # Choice 3 self.choice3 = Radiobutton( self ) self.choice3["text"] = "Mother Theresa" self.choice3["variable"] = self.current_selection, self.choice3["value"] = "Mother Theresa", self.choice3["command"] = self.set_text self.choice3.grid( row = 4, column = 0, sticky = W ) # Choice 4 self.choice4 = Radiobutton( self ) self.choice4["text"] = "Marge Simpson" self.choice4["variable"] = self.current_selection, self.choice4["value"] = "Marge Simpson", self.choice4["command"] = self.set_text self.choice4.grid( row = 5, column = 0, sticky = W ) # Choice 5 self.choice5 = Radiobutton( self ) self.choice5["text"] = "Abstain" self.choice5["variable"] = self.current_selection, self.choice5["value"] = "abstain.

I would like to bind f.e. Up and Right, so that when I press both of them, my thing moves sideward up-and-right. How to do that? Thank you -- Pavel Kosina
