Framed

Hello list, The following little test program works as expected. But if you change the line marked "----- Here ----" so it reads: self.Frame2 = Pmw.ScrolledFrame(self) then it blows up on an error deep inside Tkinter when attempting to create the button mentioned on the following line. All I wanted to do was trade a Frame for a ScrolledFrame. I'm stumped as to why it blows up. Anybody out there know? Thanks Cam ps I realize that in this example Frame2 is redundant. I encountered the problem in a larger case. To generate the example shown below I stripped out pretty much everything that wasn't necessary to demonstrate the problem. - - - - - import Pmw from Tkinter import * class Test(Frame): def __init__(self,Master=None,**kw): apply(Frame.__init__,(self,Master),kw) self.Frame2 = Frame(self) #<---- HERE ---- self.Frame2.pack(side='left') self.Button1 = Button(self.Frame2) self.Button1.pack(side='top') Root = Tk() Pmw.initialise(Root) App = Test(Root) App.pack(expand='yes',fill='both') Root.geometry('640x480+10+10') Root.mainloop()

active icons with drag-and-drop
by Eric S. Johansson April 30, 2006

April 30, 2006

I'm trying a user interface experiment. the first step involves dragging and dropping from one application onto an icon. subsequent steps will involve playing with the clipboard, icon changes, single click, double click as well as press and hold for a menu. is this something one can do with tkinter without a large amount of complexity or would I be better off looking at other toolkits including native kits? many thanks ---eric

changing button functionality
by Ilknur Ozturk April 28, 2006

April 28, 2006

I put a button (button1) and want that the user can change the function called when it is clicked. I planned such a way to realize this. The first click of it will open a new window and the user will enter a key in an entry. When he confirms it by pressing OK button, the button1 will be directed to a new function which gets the entry content as a parameter. Then the button1 will always call that function. If I can use if statement to determine the which function will be called when the button presses, it will be very helpful. Then I can call any function by checking the button's attributes with if statement. If it is not possible, how can I realize such an aim. If we can use if statement for button's command option, can you give me an example?

buttonpress
by Pavel Kosina April 25, 2006

April 25, 2006

Hi, I am not sure, if I do understand perfectly what is written in http://effbot.org/tkinterbook/tkinter-events-and-bindings.htm : When you press down a mouse button over a widget, Tkinter will automatically "grab" the mouse pointer, and mouse events will then be sent to the current widget as long as the mouse button is held down. Seems to me that mouse event is sent to to widget only once, not all time untill I release the button. The callback function is proceed only once with me. Thank you -- Pavel Kosina

Rapyd-Tk release 0.0.0
by Cam April 24, 2006

April 24, 2006

Hello Tkinter fans, The first release of Rapyd-Tk, an open source, graphical design environment for use with Python and Tkinter is now available at: http://home.cogeco.ca/~rapyd Rapyd-Tk is licensed under the GPL version 2. Please note that this is an *alpha* release (which around here at least means a pre-pre-release of brand new code). Although hundreds of hours of testing have gone into this there are certainly bugs remaining, particularly as it is used on lots of systems. I only have Linux boxes so all testing had been done on Linux although I believe it should work on that other operating system as well. Have fun :) Cam Farnell

question regarding TkinterDnD and tkDnD
by Casey Wong Kam Shun April 21, 2006

April 21, 2006

Hi Michael, First of all thanks for your reply in the Tkinter-discuss forum. I am using the TkinterDnD for a project of mine. I have the newest tkdnd installed in the newest Tcl\lib folder (activestate Tcl, it is installed in c:\Tcl), and I have followed the instruction to copy the TkinterDnD folder into the Python*\lib\site-packages folder. I am using Xp pro sp2 and python 2.2.3. I have also put the tkdnd unzipped folder into the python22\tcl folder. I would appreciate it if you could let me know what could have caused the following error when I run the dnddemo.py: TclError Exception in Tk callback Function: <function runScriptCommand at 0x019CA610> (type: <type 'function'>) Args: () Traceback (innermost last): File "C:\Program Files\Leo\extensions\Pmw\Pmw_1_2\lib\PmwBase.py", line 1752, in __call__ return apply(self.func, args) File "C:\Program Files\Leo\plugins\mod_scripting.py", line 333, in runScriptCommand c.executeScript(c.currentPosition(),useSelectedText=True,silent=True) File "C:\Program Files\Leo\src\leoCommands.py", line 1316, in executeScript exec script in d File "<string>", line 8, in ? None File "C:\Program Files\Visual Components\Python 2.2\Lib\site-packages\TkinterDnD\TkinterDnD.py", line 352, in __init__ self.TkdndVersion = _require(self) File "C:\Program Files\Visual Components\Python 2.2\Lib\site-packages\TkinterDnD\TkinterDnD.py", line 333, in _require tkdndver = tkroot.tk.call('package', 'require', 'tkdnd') TclError: can't find package tkdnd Many thanks for your help best regards Casey Wong

tkdnd installation
by Casey Wong Kam Shun April 20, 2006

Hi, I am learning how to use tkdnd and would appreciate if someone could let me know how to install tkdnd? I know there is installation instruction but it is not clear for a novice like me. For example what should I do with the libtkdnd.dll ( and the binary one-- libtkdnd10.dll) file? Many thanks regards Casey Wong

Problem with PSDraw in PIL when trying to print
by Sajjad Hussain April 17, 2006

April 17, 2006

Hi, I am trying to follow the Postscript print example in PIL. So I am using PSDraw to create a new ps file from a jpeg. I have ghostview installed, so I can view the resulting ps file (when it is produced successfully). Example from PIL Manual: import Image, PSDraw im = Image.open('lena.jpg').convert('L') box = (1*72, 2*72, 7*72, 10*72) outfp = open('lena.ps','w') ps = PSDraw.PSDraw(outfp) ps.begin_document() ps.image(box,im,72) ps.rectangle(box) ps.end_document() Now when I try to open up the lena.ps (that should contain the lena.jpg) in ghostview, I get Error: undefined gsize. However when I change the gsize to gsave in the lena.ps, the file loads up. Snippet of the actual code is show below: %%EndProlog gsize ------------------> change this to gsave 240.000000 384.000000 translate 0.960000 0.960000 scale gsave I don't know why it is happening. Can you please tell me another solution instead of changing a line manually. I just need to print a jpeg file. Is there any way else to do this. So basically I have an image in a folder, I open it and send it to a printer. Please let me know if you guys know anything.
