Subject: [Tkinter-discuss] Canvas create_line dropping pixels
Message-ID: <8D08D366-B36F-42F1-9610-2ED8100C2BE3@passcal.nmt.edu>

I'm trying to draw letters and numbers (need rotated text without  
using PMW and all the other solutions I've seen), but create_line  
drops pixels at the ends of the lines it draws.  Sometimes the  
beginning pixel is missing and sometimes the end pixel.  Is there a  
work around other than the obvious of extending the the line an extra  
pixel where necessary?  It does this on old Suns, new Macs and Windows  
(except different pixels are missing between the different OSs).  PIL  
had this problem a while back, but it was fixed with v1.1.6.

Like this should be a small "+" sign, but it is missing the end pixels  
on both lines (and just making the "+" bigger doesn't seem to help.

Can.create_line((Xx-1, Yy-1, Xx+1, Yy-1), fill = "white")
Can.create_line((Xx, Yy-2, Xx, Yy), fill = "white")

I've fiddled with the capstyle/joinstyle/arrow options, but haven't  
come up with anything.

Thanks!

Bob

Subject: [Tkinter-discuss] Can tkinter handle an animation containing 10,
	000 2d disks?
Message-ID: <BAY128-W19AB28325B6A355BEC360AB15E0@phx.gbl>


Dear Colleagues,

I am considering using python to write a simulation program to display the motions of about 10,000 2d disks. The program doesn't need to calculate the positions of disks. It just reads the result file and displays disks on the screen. I wonder whether Tkinter has this ability for rendering so many disks in time.

Thanks!

See below code which moves 10,000 small disks (6x6 pixels)
around a canvas 1000x1000 pixels, without regard to stacking order
(no z axis for disk positions), and moving disks randomly +-1 in
the x and y axis each iteration:

Takes about 1 second per iteration on my old slow windoze box:

            self.wgts.append((wid, x, y))

        while True:
            self.update1()

Subject: Hi Problem regarding Pmw and py2exe
Hi guys,
            I am a python learner. My name is Sampath Girish M. I have a
problem with Pmw toolkit during py2exe conversion process.
Traceback (most recent call last):
  File "C:\Python25\Pmw.1.3.2\src\Pmw\__init__.py", line 29, in <module>
    _dir = __path__[0]
NameError: name '__path__' is not defined

This is the error i got when i ran the file __init__.py file.

WindowsError: [Error 3] The system cannot find the path specified:
'C:\\Python25\\dist\\library.zip\\Pmw/*.*'
Traceback (most recent call last):
  File "login1.py", line 6, in <module>
  File "home1.pyc", line 8, in <module>
  File "tabbed_inv.pyc", line 11, in <module>
  File "Pmw\__init__.pyc", line 28, in <module>
WindowsError: [Error 3] The system cannot find the path specified:
'C:\\Python25\\dist\\library.zip\\Pmw/*.*'

I got the above error in Pmw to py2exe process. Please give me a solution or
anyone's mailing list. So that problem solving probability will be more.



Thanks and Regards,

Check the step 2 listed at this page.  It describes how to get PMW and 
py2exe working together.

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.

Hi Lawrence,

File system events are not a part of tk library so Tkinter doesn't process
such events.
Nevertheless native _tkinter library contains two file event related
procedures - createfilehandler() and deletefilehandler()
So you can try finding samples how to use these functions. For example:

http://mail.python.org/pipermail/python-list/1999-May/001838.html

Also you can try resolving this issue using "fileevent" tcl command:

http://www.tcl.tk/man/tcl8.5/TclCmd/fileevent.htm

But this way supposes tcl programming.

The only way I know of to do this is to use "after" to invoke a function which does the file checking and whatever else is required. That function sets another "after" - with perhaps a one second delay or whatever seems appropriate - to invoke itself. Thus the function is invoked repeatedly to keep track of the file. It isn't pretty but it works.

There are arguably easier ways.  It might be the weekend before I
can explain.  My summary:  Mr. O'Gorman can try Mr. Novikov's sug-
gestions, OR wait for the possibility of a more completed approach.

Yes, you are right. Solution without Tkinter usage is also possible. File
watcher can be created
on pure Python implementation:

Sorry I forgot this issue because this thread is a [Tkinter-discuss] :)

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()

Subject: [Tkinter-discuss] copy-enabled Label
Message-ID: <25005754.53572.1243117067536.JavaMail.www@wwinf8217>

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.

Hi O.C.

The following code shows how to use an Entry widget
which ignores all key presses except Control-c and Control-x
(copy and cut at least under windows).

from Tkinter import *

def copy1(event):
    pass

def printKey(event):
    return "break"

main=Tk()

wt=Entry(main, bg="white")
wt.insert(END, "FRed")
wt.pack(side=LEFT, fill=BOTH,expand=True)
wt.bind("<Control-c>", copy1)
wt.bind("<Control-x>", copy1)
wt.bind("<KeyPress>", printKey)
main.mainloop()

The copy-enabled label should be much easier to implement:

>>> from Tkinter import *
>>> root = Tk()
>>> e=Entry(root,relief='flat',bd=0,takefocus=0,highlightthickness=0)
>>> e.pack()
>>> e.insert('end', 'foobar')
>>> e.config(state='readonly')

Regards

Hi Michael,

  Ahhh, my tkinter manual does not contain the state='readonly'
property. Seems I need to update my manual (John Shipman's
from 2003).

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'.

Mick

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 :

In fact I am using a "textvariable" link, so I don't need to do this.

Regards,

O.C.

You also need the Tcl BWidgets package.

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? Thank you so much.

You'll need to include it somehow with the Tcl/Tk libaries that you wrap 
with py2exe. Not sure how that works since I don't develop on Windows.

Subject: [Tkinter-discuss] Adding <Command-Button-1> to a Listbox
Message-ID: <DBF35E8D-FFEE-4E5D-AD95-04F29A77C354@passcal.nmt.edu>

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

I think

    root = Tk()
    root.bind_class('Listbox', '<Command-Button-1>', root.bind_class('Listbox', '<Control-Button-1>') )

should do the trick.

Michael

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!!

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
