hi

I have a function defined using os.system("mount ....."). as a
callback to a button.

On clicking this button the system asks for password in terminal. How
do i enter this password in a tk window so that the system reads it
?.Iam using the entry widget to do this.

Here's code I use for this:

     #get user password to run commands as root
     def authorizeCommand(self, cmd):

         self.passtext = StringVar()
         self.password = Toplevel(self)
         self.password.title('Password Required')

         self.passtop = Tkinter.Frame(self.password, padding=5)
         self.passtop.pack(side=TOP, fill=BOTH, expand=YES)

         self.passlabel =  Tkinter.Label(self.passtop, text='You must 
enter your password.')
         self.passlabel.pack(side=TOP, fill=BOTH, expand=YES)
         self.passlabel.image=self.lock

         self.passentry = Tkinter.Entry(self.passtop, show='*', 
textvariable=self.passtext)
         self.passentry.pack(side=BOTTOM, fill=BOTH, expand=YES)
         self.passentry.bind('<Return>', (lambda event: 
self.runCommand(cmd)))

         self.passbottom = Tkinter.Frame(self.password, padding=5)
         self.passbottom.pack(side=BOTTOM, fill=BOTH, expand=YES)

         self.bottomupper = Tkinter.Frame(self.passbottom)
         self.bottomupper.pack(side=TOP, fill=BOTH, expand=YES)

         self.bottomlower = Tkinter.Frame(self.passbottom, padding = 5)
         self.bottomlower.pack(side=BOTTOM, fill=BOTH, expand=NO)

         self.passinstall = Tkinter.Button(self.bottomlower, text='OK', 
default=ACTIVE, command=lambda: self.runCommand(cmd))
         self.passinstall.grid(row = 1, column = 1, sticky = NSEW)

         self.passcancel = Tkinter.Button(self.bottomlower, 
text='Cancel', command=self.password.destroy)
         self.passcancel.grid(row=1, column = 0, sticky = NSEW)

  #run command with root privileges
     def runCommand(self, cmd):

        self.passtext=self.passtext.get()
        self.password.destroy()
        cmd()

Subject: [Tkinter-discuss]  Tkinter.bind(),
 watching for mouse click and release inside a canvas
Message-ID: <13811890.post@talk.nabble.com>


My goal is to write a clip of code so that a user can click inside a canvas,
drag and release to make a crop box of his size, then crop. So after looking
around at pages like
http://www.pythonware.com/library/tkinter/introduction/events-and-bindings.htm,
I figure I can:

canvas.bind('<Button-1>', func1)
canvas.bind('<B1-Motion>', func2)
canvas.bind('<ButtonRelease-1>', func3)

Currently I can print the variables, but is there any way to actually return
the x,y coordinates of the mouse and store them in a variable? This is part
of a larger photo editor project, but in general I want to be able to watch
for mouse clicks and return position values... any idea as to how?

func1, func2 and func3 are called with one argument, which is
an event object.

You can then access event.x and event.y

e.g.,

def func1(event):
  print event.x, event.y

Subject: [Tkinter-discuss]  .mainloop(), what's the parameter for?
Message-ID: <13836178.post@talk.nabble.com>


Tkinter.py defines mainloop with a single parameter n=0.  Does anyone know
what this parameter is for?  I've tried some experimenting and found that if
I pass anything other than 0, mainloop seems to execute at least one
complete interation without reporting an error, then it returns.  Could this
be what the parameter is for?  To allow a user to write his own mainloop?

Thanks,
Ron

Hi Ron,

I didn't know that parameter either, so I thought I'd take a look.
I found the following loop in 'Tkapp_MainLoop' in '_tkinter.c':

while (Tk_GetNumMainWindows() > threshold &&
      !quitMainLoop &&
      !errorInCmd)
{
...

The parameter 'n' is the 'threshold' in the above 'if'.
If I understand the man-page of 'Tk_GetNumMainWindows' right
the code above drops out of the 'mainloop' when the
number of toplevel windows drops to 'threshold' or below.

Has anyone used this for values other than '0'?
I have never seen code using this.
What is the idea? Close the application when one of the
main windows gets closed?

Subject: [Tkinter-discuss] Problems to show menubar
Message-ID: <a6efcfc50711260454of88e495x9b8df723ac337ab4@mail.gmail.com>

Hello,

i just starts with Tkinter and started with a small GUI where i want to show
a menubar. but it does not work. Here is the code:

---------------------------------------------------------------------------------------------------
from Tkinter import *

class DistManager(Frame):
    def __init__(self, master=None):
        Frame.__init__(self, master)
        self.grid()
        self.createMenuBar()
        #self.createLogin()

    def createLogin(self):
        Label(self, text="Bitte geben Sie Ihre Zugangsdaten ein",
pady=10).grid(row=0, column=0, columnspan=2)
        Label(self, text="Name: ", pady=10).grid(row=1, column=0)
        Label(self, text="Passwort: ", pady=10).grid(row=2, column=0)
        NameEntry=Entry(self)
        PasswortEntry=Entry(self, show="*")
        NameEntry.grid(row=1, column=1)
        PasswortEntry.grid(row=2, column=1)
        AbbruchButton=Button(self, text="abbrechen")
        AnmeldenButton=Button(self, text="anmelden")
        AbbruchButton.grid(row=3, column=0)
        AnmeldenButton.grid(row=3, column=1, sticky="e")

    def createMenuBar(self):
        menubar=Menu(self)
        kundenmenu=Menu(menubar, tearoff=0)
        kundenmenu.add_command(label="Kunden anzeigen")
        kundenmenu.add_command(label="Kunden anlegen")
        kundenmenu.add_command(label="Kunden bearbeiten")
        menubar.add_cascade(label="Kunden", menu=kundenmenu)

        self.config(menu=menubar)


app=DistManager()
app.master.title("CCB- DistributionsManager")
app.master.geometry("800x600")
app.mainloop()
-------------------------------------------------------------------------------------------------
The menu option in self.config should be the problem. Does anybody know how
to show the menubar works (in my case)

Mathias

Hi Mathias,

you need to attach your menubar to a Toplevel window.
A simple Frame cannot have a menubar.
It works, if you change your code like this:

------------------------------------------------
from Tkinter import *

class DistManager(Frame):
    ...
    def createMenuBar(self):
        menubar=Menu(self)
        kundenmenu=Menu(menubar, tearoff=0)
        kundenmenu.add_command(label="Kunden anzeigen")
        kundenmenu.add_command(label="Kunden anlegen")
        kundenmenu.add_command(label="Kunden bearbeiten")
        menubar.add_cascade(label="Kunden", menu=kundenmenu)

        self.master.config(menu=menubar)


tk = Tk()
app=DistManager(tk)
app.master.title("CCB- DistributionsManager")
app.master.geometry("800x600")
tk.mainloop()
----------------------------------------------------

The menu is attached to the master.
The master must be a widget that can have a menu, like
Tk itself or a Toplevel window.
Another method would be to derive DistManager
from Toplevel (haven't tried though).

Sch?ne Gr??e,

Subject: [Tkinter-discuss] General Doubt about tkinter windows...
Message-ID: <002101c83257$99c00160$2000a8c0@depid.local>

Hi all,

 

I am trying to develop a simple application in python (I am very newby), but
I have some general doubts
 my main window is Tk(), I am using grid manager,
and when in the application user changes the view, what I do is take a frame
out of the grid and put another one (and sometimes there are position
changes of other remaining frames :-S). My doubt is how can I change the
window?? Because if I use Toplevel window, main window remains under it, and
user can also continue changing it, what I don?t want, I just want one
active window in every moment. Could you give me some hints of how doing it?

 

Thanks in advance

 

Best regards,
