Possibly n00bish question about ImageTk
by Barnesdesdes Feb. 10, 2009

Feb. 10, 2009

I've been trying to make a program which will import a png file and display it inside a frame. It actually works when I just run the code, but if I try to abstract the exact same code into a function, it fails. In the code below, if I just run it, it works. However, if I comment out the lines between "root=Tkinter.Tk()" and "moo(root)" and comment in "moo(root)", it no longer works. Instead of displaying the image, it just displays a gray frame of the correct size. Does anyone have any insights about what I'm doing wrong? import Image, ImageTk, Tkinter def moo(master): img = Image.open('plotfig.png') f = Tkinter.Frame(master, width=800, height=600) pi = ImageTk.PhotoImage(img) t = Tkinter.Label(f, image=pi) f.pack() t.place(x=0, y=0, width=800, height=600) t.pack() root = Tkinter.Tk() img = Image.open('plotfig.png') f = Tkinter.Frame(root, width=800, height=600) pi = ImageTk.PhotoImage(img) t = Tkinter.Label(f, image=pi) f.pack() t.place(x=0, y=0, width=800, height=600) t.pack() #moo(root) root.mainloop() Thanks very much.

Shareware product using Tkinter
by Kevin Walzer Jan. 7, 2008

Jan. 7, 2008

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I know there is a lot of talk about Tkinter being an antiquated toolkit, unsuitable for commercial software development. However, I am using Tkinter in one of my shareware programs: http://www.codebykevin.com/packetstream.html (there's a screenshot) This application makes use of some recent advances in Tk development, including Tile (see http://tkinter.unpythonic.net/wiki/TileWrapper for the Python wrapper). It also makes use of some nice Tkinter widgets such as ToolTip (http://tkinter.unpythonic.net/wiki/ToolTip). If you pay attention to some of the specifics of the platform you are targeting (this app is for Mac OS X users) and to other points of application design, such as icons (I find the Tango set to be very polished and well-suited for the Mac; it doesn't scream "Linux"), then I think it's quite possible to make a nice, polished, professional-looking application with Tkinter. I'm curious if anyone has thought about gathering a listing of other Tkinter applications, commercial or otherwise, that are well-designed/attractive. Perhaps a screenshot page at the Tkinter wiki or elsewhere? - -- Kevin Walzer Code by Kevin http://www.codebykevin.com -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (Darwin) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD4DBQFFntpOEsLm8HXyq4sRAuxMAJQOpHKZf9dGrxO/0F0UVIPMr8vZAJsGIHT9 pYgEgO+j2Q83GocIWWOzqA== =7aqI -----END PGP SIGNATURE-----

General Doubt about tkinter windows...
by Jose Ignacio Gisbert Nov. 29, 2007

Nov. 29, 2007

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 dont 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, _______________________________ José Ignacio Gisbert Sanus

Re: [Tkinter-discuss] Problems to show menubar
by mkieverpy＠tlink.de Nov. 26, 2007

Nov. 26, 2007

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). Schöne Grüße, Matthias Kievernagel (mkiever/at/web/dot/de)

Problems to show menubar
by Mathias Uebelacker Nov. 26, 2007

Nov. 26, 2007

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) br Mathias

Re: [Tkinter-discuss] .mainloop(), what's the parameter for?
by mkieverpy＠tlink.de Nov. 20, 2007

Nov. 20, 2007

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?

.mainloop(), what's the parameter for?
by ron.longo Nov. 19, 2007

Nov. 19, 2007

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?

Tkinter.bind(), watching for mouse click and release inside a canvas
by aonomus Nov. 17, 2007

Nov. 17, 2007

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.…, 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? -- View this message in context: http://www.nabble.com/Tkinter.bind%28%29%2C-watching-for-mouse-click-and-re… Sent from the Python - tkinter-discuss mailing list archive at Nabble.com.
