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?

Thanks, I found out how to see the original message. It comes in as an attachment ("Untitled attachment") to the email posted by the list. If I open that attachment there is a further attachment (style is "ATT5107.txt") which up until now I had assumed was some form of signature block (I get similar things on emails from friends in other companies - they contain nothing worthwhile viewing) so I never thought to venture further. So any emails from Jeff need to have three levels opened before I can see the original text - glad I saved all those emails, now I can see what was in them! :-) Thanks for the help, Peter > -----Original Message----- > From: Fredrik Lundh [mailto:fredrik@pythonware.com] > Sent: Tuesday, November 30, 2004 7:22 PM > To: tkinter-discuss(a)python.org > Subject: [Tkinter-discuss] Re: bwidget progression dialog > > > Stewart Midwinter wrote: > > > It appears that the progression dialog (shows a little > rectangle that > > oscillates back and forth to indicate progress of a > process) would be > > quite useful in what I'm doing. > > Slightly OT: if you have the WCK, you can use this progress bar > instead: > > http://effbot.org/zone/wck-progressbar.htm > > </F> > > > > _______________________________________________ > Tkinter-discuss mailing list > Tkinter-discuss(a)python.org > http://mail.python.org/mailman/listinfo/tkinter-discuss > Warning: Copyright ResMed.

Anybody else get this little of Jeff's postings? Everything I get from Jeff looks like below. Is there something in my Microsoft Outlook setup that I should change? It would be really interesting to get more than the email signature, I'm sure he has something interesting to say..... :-) Thanks Peter P.S. It is only Jeff's postings that get stripped this way, every other posting has the content intact. > -----Original Message----- > From: Jeff Epler [mailto:jepler@unpythonic.net] > Sent: Tuesday, November 30, 2004 6:24 AM > To: Stewart Midwinter > Cc: tkinter-discuss(a)python.org > Subject: Re: [Tkinter-discuss] using pybwidget > > > _______________________________________________ > Tkinter-discuss mailing list > Tkinter-discuss(a)python.org > http://mail.python.org/mailman/listinfo/tkinter-discuss > Warning: Copyright ResMed.

bwidget progression dialog
by Stewart Midwinter Nov. 30, 2004

Nov. 30, 2004

It appears that the progression dialog (shows a little rectangle that oscillates back and forth to indicate progress of a process) would be quite useful in what I'm doing. Does anyone have a sample code of how to set it up under Python? I can get the progression dialog to pop up, but I'm clearly lacking in understanding how to display the oscillating rectangle or have it update. My sample code below includes the TCL code that displays the progression dialog and its bar. === # sample code from Tkinter import * from bwidget import * t = Tk() b = Button(t, relief=LINK, text="Quit (using bwidget)", command=t.destroy) b.pack() c = ProgressDialog(t, title="Please wait...", type="infinite", width=20, stop="Stop", ) #d = Button(c, text="end", command=c.destroy) t.mainloop() """from Tkinter import * from bwidget import * progmsg = "Compute in progress..." progval = 0 t = Tk() b = Button(t, relief=LINK, text="Quit (using bwidget)", command=t.destroy) b.pack() c = ProgressDialog(t, title="Please wait...", type="infinite", width=20, stop="Stop", textvariable = progmsg, variable = progval ) #d = Button(c, text="end", command=c.destroy) t.mainloop() """ TCL code from tmpldlg.tcl that creates a progression dialog: proc DemoDlg::_show_progdlg { } { set DemoDlg::progmsg "Compute in progress..." set DemoDlg::progval 0 ProgressDlg .progress -parent . -title "Wait..." \ -type infinite \ -width 20 \ -textvariable DemoDlg::progmsg \ -variable DemoDlg::progval \ -stop "Stop" \ -command {destroy .progress} _update_progdlg } proc DemoDlg::_update_progdlg { } { if { [winfo exists .progress] } { set DemoDlg::progval 2 after 20 DemoDlg::_update_progdlg } } """ cheers, -- Stewart Midwinter stewart(a)midwinter.ca stewart.midwinter(a)gmail.com

Yeah, I could but it's strange that this is the only mailing list and the only person for that matter where this happens. It sort of defeats the purpose (to my mind :-)) of subscribing to a list... I just thought there might be something simple I could do or perhaps there might be others in the same boat (sinking) that I am > -----Original Message----- > From: Stewart Midwinter [mailto:stewart.midwinter@gmail.com] > Sent: Tuesday, November 30, 2004 7:22 AM > To: Peter Milliken > Cc: tkinter-discuss(a)python.org > Subject: Re: [Tkinter-discuss] using pybwidget > > > Peter, it might just be easier to read the mailing list on > gmane.org, at: > http://news.gmane.org/gmane.comp.python.tkinter > > > > > On Tue, 30 Nov 2004 06:32:17 +1100, Peter Milliken > <peterm(a)resmed.com.au> wrote: > > Anybody else get this little of Jeff's postings?

using pybwidget
by stewart＠midtoad.homelinux.org Nov. 29, 2004

Nov. 29, 2004

Jeff: ok, I've got it installed, and I can open the demo.tcl app using TCL, which I have installed on my system as well. But how would I, say, run the demo app using python code? Somehow I have to 'import pybwidget', since I see an __init__.py in a ..\lib\site-packages\bwidget folder, but then what? do you have any more examples of its use? thanks, Stewart

Tkinter >> Using Pmw OptionMenu: too many options
by Albert Su Nov. 24, 2004

Nov. 24, 2004

Hi everyone, I want to have a selection menu that displays a long selection list. However, I am getting problems with displaying the entire list because it gets cut off from the bottom of the screen. I believe the list continues on, just that it cannot be displayed. Is it possible to add in a scroll bar, or a "wrap" function of some sort? Thanks in advance, Albert

Announcing wrappers for bwidget
by Jeff Epler Nov. 23, 2004

Nov. 23, 2004

I have written a set of wrappers for "bwidget". bwidget is a collection of enhanced widgets written in pure TCL, from a tweaked Button widget to a snazzy-looking NoteBook (tabset) widget. The bwidget wrappers, which include a copy of BWidget 1.7.0, can be found at http://tkinter.unpythonic.net/bwidget/ and a copy of the bwidget documentation (written for people writing tcl) is nearby: http://tkinter.unpythonic.net/bwidget/BWman/ As the README says: Please report your experiences, good or bad, on the Tkinter mailing list pybwidget is written on Fedora Core 2 with Python 2.3 and Tk 8.4, but may work on other releases of Python. I'm aware that Fredrik Lundh has given this a try too (http://effbot.org/zone/bwidgets.htm) but I never looked at his work before starting on this, so I don't know how they compare. CLASSES BWidget ArrowButton(BWidget, Tkinter.Button) Button(BWidget, Tkinter.Button) ButtonBox(BWidget, _Items, Tkinter.Frame) Dialog(ButtonBox, Tkinter.BaseWidget, _Frame) MessageDialog PasswordDialog ProgressDialog SelectColor SelectFont Entry(BWidget, Tkinter.Entry) ComboBox LabelEntry SpinBox Label(BWidget, Tkinter.Label) LabelFrame(BWidget, _Frame, Tkinter.Widget) ListBox(BWidget, Tkinter.Widget, _Items) MainFrame(BWidget, _Frame, Tkinter.Widget) PagesManager(BWidget, Tkinter.Frame) NoteBook(PagesManager, _Items) PanedWindow(BWidget, Tkinter.Frame) PanelFrame(BWidget, Tkinter.Frame) ProgressBar(BWidget, Tkinter.Widget) ScrollView(BWidget, Tkinter.Widget) ScrollableFrame(BWidget, _Frame, Tkinter.Frame) ScrolledWindow(BWidget, _Frame, Tkinter.Frame) Separator(BWidget, Tkinter.Widget) StatusBar TitleFrame(BWidget, _Frame, Tkinter.Frame) Tree(BWidget, Tkinter.Widget, _Items)

Inserting a unicode zero-width nonbreaking space into a Text widget, from Tkinter, on a Mac
by Kenneth McDonald Nov. 3, 2004

Nov. 3, 2004

As the subject says, I am attempting to insert a particular unicode character (\ufeff) into a Text widget, from Python. This is not quite working correctly, and I'm not sure if the problem is between Python and Tcl, or is a problem of OS X not properly knowing the character. This character is supposed to be a 0-width space, and using Python's unicodedata.name function confirms that feff is in fact the proper unicode sequence. The character is construction using a one-character python string: zws = u"\ufeff" And then passed to Text's insert command. Unfortunately, what shows up on screen is a complex (perhaps Chinese) asian ideograph. "Python in a Nutshell" indicates that all communication between Tkinter and Tk is in unicode, so I had hoped this would transfer correctly. Not sure if I need to do some conversion or not...could there be a conflict between a straight Unicode (16-bit) representation and a UTF-8 representation? Or do I need to do an OS setting to make sure the OS and the internal representation are on the same wavelength? Thanks, Ken
