Tkinter clipboard_get method...
by Martin Franklin April 12, 2005

April 12, 2005

Hi all, I just submitted a patch to python (SF #1063914) that adds the clipboard_get method. As it stands this method will raise a TclError if it is called and the clipboard (the system clipboard) is empty... my question is therefore should I catch this exception in the Tkinter clipboard_get method (and return an empty string / None?) or let the user worry about it?

Tile themeing engine

Has anyone got the Tile themeing engine (from http://tktable.sf.net) working with Tkinter? If so, how'd you do it? Instructions on the site don't give much clue for Python users. thanks, -- Stewart Midwinter stewart(a)midwinter.ca stewart.midwinter(a)gmail.com

thanks Mark, I've patched up my tktable.py. Now I'm trying to get it running under Windows without success. Are you by any chance running it under Windows yourself? cheers S On Thu, 30 Dec 2004 12:06:02 -0000, Mark English <Mark.English(a)liffe.com> wrote: > > I had this problem and hacked together what looked like fixes as a patch. -- Stewart Midwinter stewart(a)midwinter.ca stewart.midwinter(a)gmail.com

I had this problem and hacked together what looked like fixes as a patch. https://sourceforge.net/tracker/?func=detail&aid=1088468&group_id=11464& atid=311464 The two changes I threw into tktable.py were to do with the call to tk.call returning a tuple of strings rather than the expected string delimited by spaces in curselection: Changed line 144 From return self._getCells(self.tk.call(self._w, 'curselection')) To return self._getCells(' '.join(self.tk.call(self._w, 'curselection'))) and to handle getting index returning an int: Changed line 173 From return self._getCells(self.tk.call(self._w, 'index', index, rc))[0][0] To return self.tk.call(self._w, 'index', index, rc) Don't know if these changes are correct in all situations but they got the demo working without errors.

pybwidget newbie questions re: Tree
by Arthur C Dec. 22, 2004

Dec. 22, 2004

I've been slowly getting up to speed on the BWidget package and since I'm using Python, the pybwidget wrapper. So far so good with some nuances encountered: - the .xpm files in the images directory don't get auto installed. There was one demo that gack'd without them. I just copied them in but modifying the setup.py file to include them is likely sane no? - I've gotten used to Tkinter's definition of constants such as NORMAL (which is merely a string 'normal') for certain argument values. When adding nodes off the root to a Tree, the Tcl code uses the name root. I was expecting to do something like: t = Tree( ... ) t.insert( END, ROOT, text = 'Something' ) Okay, so not ROOT constant exists. So, what do I use? I'm guess 'root'. Changed the code to: t.insert( END, 'root', text = 'Something' ) Now, I want to delete all the nodes in the tree. So I want to do something like: t.delete( t.nodes( 'root' ) ) However, doing so gives the following error: TclError: wrong # args: should be "Tree::nodes path node ?first? ?last?" Any idea what the issue is? FYI, I'm using pybwidget-0.1.1_1.7.0 Thanks for any clues offered. Regards, Arthur

getting data out of a Bwidget Password Dialog
by Stewart Midwinter Dec. 14, 2004

Dec. 14, 2004

I've been looking through the Bwiddgets, and adding some documentation to the Tkinter wiki. I'm struggling with the password dialog. I can draw one, but I can't get the data out of it. I've looked into the .tcl for clues, and it appears that the class may return a list containing the login and password, but I can't figure out how to get that data! Any clues? Here's what I have so far: from Tkinter import * from bwidget import * t = Tk() t.title('password') global p def printMe(s): print s print p.get() p.destroy() b = Button(t, relief=LINK, text="Quit", command=t.destroy) b.pack() p = PasswordDialog(t, type="okcancel", labelwidth=10, command=lambda s='have pwd': printMe(s)) t.mainloop() thanks, -- Stewart Midwinter stewart(a)midwinter.ca stewart.midwinter(a)gmail.com

Screen Resolution for tkinter
by Albert Su Dec. 14, 2004

Dec. 14, 2004

hi everyone, I am currently writing a GUI that is meant to run on different window managers with different resolutions. How can I scale down the size of my app when running on lower resolutions? I managed to find out the resolution of the screen I'm running on through winfo calls, but I can't specify the width/height of any frames/root frames/top levels I create. Any winfo_width() or winfo_height() calls to any frame gives me a 1, 1. Also, can I specify button sizes and the font size used for it? I am currently using grid() as the way of adding widgets into a frame. Thanks for any help, Albert

TkTable problem
by Stewart Midwinter Dec. 13, 2004

Dec. 13, 2004

Anyone have any success getting the sample table.py script, a demo for TkTable, to run properly? I am able to install TkTable, and run the script, but as soon as I select, i.e. click on, a cell, the thing throws an exception. Apparently the selection process selects an entire row instead of a cell, so a routine expecting a string,e.g. '2,1' instead gets a tuple, e.g ('2,0', '2,1', '2,2). I just can't quite figure out where the error is occurring. As an alternative, does anyone have a small sample showing use of a table widget, including editing cell contents and capturing the changes? thanks, -- Stewart Midwinter stewart(a)midwinter.ca stewart.midwinter(a)gmail.com
