Tkinter - resize tkMessageBox
Hi, Is there a way to resize the width of the "tkMessageBox.askyesno" dialog box, so that the text does not wrap to the next line. Thanks Rahul -- http://mail.python.org/mailman/listinfo/python-list
Tkinter - Force toplevel window to stay on top of Tk() window
Hi, I have a Tk() window "base_win = Tk()" with multiple frames on it having a combination of widgets. If I click on say a button widget which launches a new top level window "new_win = TopLevel()", I was looking for a way for this "new_win" to always stay on top of "base_win" till I close "new_win", as a result also not allowing any selections to be made in the "base_win" . Thanks Rahul -- http://mail.python.org/mailman/listinfo/python-list
tkinter listboxes
I will give a simplified example of the problem at hand -- I have a case in which I have two listboxes - listbox1 and listbox2, if I click on an item in listbox1 the item gets highlighted as expected. Now if I click on an item in listbox2 the selected item in listbox1 loses its highlight. My question is how do I keep the listbox1 item from losing its highlight if I select an item in listbox2 or to that matter any other widget. Thanks Rahul -- http://mail.python.org/mailman/listinfo/python-list

tkinter - label widget text selection
Hi, I guess this is a very trivial question -- I am using a label widget to display text (black font in a white background color). I am trying to use my mouse to scroll over the displayed text to select it, but tkinter does not allow me to do it. Is there a method/option to do this. Thanks Rahul -- http://mail.python.org/mailman/listinfo/python-list

tkinter get widget option value

tkinter - Screen Resolution
Hi, I have developed a GUI using tkinter (grid geometory manager). The structure is a top frame containing multiple subframes. Each subframe has a combination of widgets like(Entry, label, button,listboxes). The subframes are placed with a padx and pady offset with regards to the other subframes. And the widgets within these subframes have their own padx and pady offsets. The GUI runs fine on my linux box, but on a different linux box things get wierd. I see things like- 1) The frame width increasing 2) The widget padx translating to much bigger offsets with reference to the subframe edges 3) Widget widths like that for Entry become bigger I Know its to do with the screen resolution settings and user settings on different machines. Can anyone point me in the right direction(before I start looking into it)as how to account for different screen resolutions so as to have as uniform a GUI look as possible across different user machines. A smaller version of my GUI layout looks something like--> ===Top Frame= =- SubFrame - -SubFrame- =-- - ' - =-- - ' Widget ' - =-- - ' - =- Widget - - =- - =-- -SubFrame- =-- - - =-- - ' - =- Widget- - ' Widget ' - =-- - ' - =-- - - =-- - ' - =-- - ' Widget ' - =- Widget- - ' - =--- - = Thanks Rahul -- http://mail.python.org/mailman/listinfo/python-list

tkinter button state = DISABLED
I have created a button widget with a button click binding. The button
initially has a state=disabled. I can see the greyed out version of
the button in the GUI. But If I click on the button it still invokes
the callback/binding function.
Any suggestions as to why the callback is being invoked even though
the button has a disabled state. It looks like-
b=Button(frame, text = "Button", state = 'disabled')
b.bind("",
lambda
event :
function()
)
Thanks

So, then is it right to say that for a widget like button widget on
occurance of a 'event' the function which is bound to this event is
invoked, even if the button widget has its 'state' option set to
'disabled'. I was assuming that if the button widget has state =
'disabled' then even on a button event the binding function wont be
invoked.
I will take a look at the alternative code you suggested above too.
Thanks

Listbox - Active index
Hi, I am using a listbox in selectmode = MULTIPLE, I can get the current selected item in the listbox from index = "ACTIVE" , but is there a way to convert this "ACTIVE" to get the current selection index as a number. For multiple selectmode listboxes it returns a tuple of selected indexes, so I would have to write some extra code to get the current active selection index from the tuple, instead I was hoping there would be a way to get the current selection index number from the "ACTIVE" index.
