Adding <Command-Button-1> to a Listbox
by Bob Greschke June 7, 2009

June 7, 2009

I'd like to add <Command-Button-1> (i.e. use the Command key on a Mac) event handling to a Listbox so that it behaves just like the <Control- Button-1> "built-in" behavior (selecting/deselecting individual items when the selectmode is EXTENDED). What should the bind statement call to do that? Can it be done through something like an option_add so it applies to all listboxes in an application? Thanks! Bob

Re: [Tkinter-discuss] Bwidget to EXE
by bobo May 27, 2009

May 27, 2009

I have kicked out this problem. The main problem comes from a segment of bwidget __init__.py code: _datadir = os.path.join(sys.prefix, "share", "pybwidget") It means the path of bwidget main modules. And it exsits in my d:\python25\ . So I copy this folder into my current exe folder, then everything runs well. By the way I have test it with both py2exe and pyinstaller. Thank you all of you!! 在2009-05-27，"Bobby Metz" <bwmetz(a)gmail.com> 写道： I haven't done py2exe work in years, but as I recall I never had any issues with installed Python modules except when my code's import statements were incorrect or missing. Now homemade modules were a different story. To get py2exe to recognize them I would use the sys.path.append command to include the sub-dir in which I stored my custom modules within the project. Example: sys.path.append("./modules") Perhaps this would help you if all else fails. Regards, Bobby 2009/5/25 bobo <kkk-mmm(a)163.com> OK, I will try it now. Thank you for you suggestion! >bobo wrote: >> Yes, I have had the BWidget-1.8.0 for Tcl, but I don't know how to install it or put them somewhere. Could you explain it more clearer?

by bobo May 26, 2009

May 26, 2009

Hi I tried to complie my python script into exe file for running on Windows, and I have tried py2exe and pyinstaller. Both of them notice this kind of problem. It seem they don't support bwidget. I am running Python 2.5.4 with pybwidget 0.1.2. Could anyone can help with me? Thank you very much. Run: xxx....in __init__ xxx....in _require_tkinter.TclError: can't find package BWidget Complie: W: __all__ is built strangely at line 0 - bwidget (D:\python25\lib\site-packages\bwidget\__init__.pyc)

Re: [Tkinter-discuss] copy-enabled Label
by oc-spam66 May 25, 2009

May 25, 2009

Hello, @ Michael Lange : thank you for the keyword : state='readonly'. This is what I needed. It doesn't show in any of the general documentation I had on Tkinter, but it is indeed in the Tk man page of the "Entry" widget. @ Michael O'Donnell : > The original poster should note that every time you want to change > the text displayed, you need to change the state to normal, change the > text, and then re-assert state='readonly'. In fact I am using a "textvariable" link, so I don't need to do this. Regards, O.C.

copy-enabled Label
by oc-spam66 May 24, 2009

May 24, 2009

Hello, my application displays the result of a calculation in a Label. I would like the user to be able to copy this result somewhere else. I don't know how to enable this. I read on a mailing list that I could use a state=DISABLED Entry widget, but this doesn't work (I can't select anything with the mouse when it is DISABLED). I also found some complicated tcl/tk code which I did not understand. How to do ? I think a copy-enabled Label is a must. Best regards, O.C.

Re: [Tkinter-discuss] non-GUI event detection in Tkinter mainloop()
by O'Gorman, Lawrence (Larry) May 21, 2009

May 21, 2009

Thanks very much to all those who responded to me and thanks to my good buddy and Python wiz, Kirke. I've included my code below, which periodically checks if a file is changed, and if so, it changes the image displayed in a window. The trick (as suggested) was to use "after" to get the event to repeatedly call itself. In the code below this is showStatus.after() at the end of the checkFileMod() function. -- import Tkinter import os root = Tkinter.Tk() # initialize parameters checkFile = "C:/BTL/Code/GC/IPSi/test3.txt" # check if this file changed img1=Tkinter.PhotoImage(file='./img1.gif') # display image 1 img2=Tkinter.PhotoImage(file='./img2.gif') # display image 2 interval = 3000 # time [msec] between checking # label widget shows status of image being displayed showStatus = Tkinter.Label() showStatus.pack() # canvas widget displays image that changes when file changes canvas=Tkinter.Canvas(root, width=400, height=400) canvas.create_image(145,280, image=img1) canvas.bind("<Button-1>", quitThis) # bind left mouse button to quit app canvas.pack() # function quits application def quitThis(event): canvas.destroy() root.destroy() root.quit() # function changes canvas if file is modified def checkFileMod(): global imgNum global fileStatus, fileStatusB4 fileStatus = os.stat(checkFile) print "file status: ", fileStatus.st_mtime if fileStatus != fileStatusB4: print "CHANGED" if imgNum == 1: showStatus.config(text="img2") imgNum = 2 canvas.create_image(145,280, image=img2) canvas.pack() else: showStatus.config(text="img1") imgNum = 1 canvas.create_image(145,280, image=img1) canvas.pack() fileStatusB4 = fileStatus showStatus.after(interval, checkFileMod) # run with initial values before loop imgNum = 1 showStatus.config(text="img1") fileStatusB4 = os.stat(checkFile) # file status before #loop checkFileMod() showStatus.mainloop()

non-GUI event detection in Tkinter mainloop()
by O'Gorman, Lawrence (Larry) May 20, 2009

May 20, 2009

I'm trying to figure out if Python and Tkinter can offer a solution to my following problem. I want to monitor a file and when that file is changed, I want to detect that event and have my window change its text from "File Unchanged" to "File has Changed." That is, I can produce a function to periodically sample the modification time of a file and if it is different than my last sample time, then this function will return an indication that the file is changed. I want this file-change event to be captured by the tkinit mainloop(), which I will then use to change the appearance of my window. I understand that any GUI event (mouse, keyboard, etc.) can be detected in the mainloop(), but I have seen no indication in the documentation and discussions that a file-change can produce an event that can be detected in the mainloop(). Does anyone know if I can do this? If so, how? Or, if there is an alternative way than mainloop() to get a window to change upon a file-change, that would be helpful, too.
