getvalue fails on pmw.radioselect after using configure on component
by ethoms Oct. 31, 2009

Oct. 31, 2009

I am using a generic function to build Pmw.RadioSelect widgets: def make_checkbuttons(self, parent, buttonlist): """Make a multiple-selection Pmw.RadioSelect checkbuttons""" widget = Pmw.RadioSelect(parent, selectmode = 'multiple', buttontype = 'checkbutton', orient = 'vertical') widget.pack(side = 'left', expand = True, fill = 'both', padx = 4) for button in buttonlist: widget.add(button) return widget In one instance I want to configure the options on three checkboxes after the generic creation of the widget: #after the generic construction of this radio button group, #we need to set some specific parameters self.var1 = IntVar() self.var4 = IntVar() self.generalops.button('all maps same data frame').configure(state = 'disabled', padx = 15) self.generalops.button('leave ArcMap open').configure(command = self.leave_open, variable = self.var1) self.generalops.button('export plots').configure(command = self.export_plots, variable = self.var4) #doesn't matter if I pack before or after the post-configuration self.generalops.pack(side = 'left', anchor = 'w') But, if I do that, self.generalops.getvalue() returns nothing for those buttons which have been post-configured. Any suggestions? -- View this message in context: http://old.nabble.com/getvalue-fails-on-pmw.radioselect-after-using-configu… Sent from the Python - tkinter-discuss mailing list archive at Nabble.com.

Need help on gui focus l
by BlackKnight Oct. 26, 2009

Oct. 26, 2009

Hi folks, I am using Tkinter to do a simple GUI for my program. It contains A MainGui and A ChildGui: A button on the MainGUI will popout the childgui. On the childgui there is a browse button which popout a dialog to allow user to browser and choose a file. I have no problem at doing them. The problem is after the uesr choose a file the focus will return to the MainGui intead of the childgui. The child gui just go hide behind the Main. I've tried focus_set, focus_force but none of them seem work. I did some research but found nothing working. It's not a big problem, but is really really annoying. (Actually I notice the examples from some python book I am reading has the exact same problem. The author even tried to spawn the child gui away from the main one, so when the focus return from the browse dialog , the maingui won't block the child one~~ Is that how tkinter should work?) Any suggestions? Thanks in advance~~ Frank

Grid Geometry Manager & ImageTk.PhotoImage
by buckr02 Oct. 23, 2009

Oct. 23, 2009

I cannot for the life of me figure this out. I am trying to create a program that will display images and have some functions to go along with it. I am using the grid manager to organize everything, and the basic framework is as such: * 2x2 grid * Row 0, Column 0 is first image * Row 0, Column 1 is second image * Row 1, Column 0 is first toolbar * Row 1, Column 1 is second toolbar I am having trouble with the images, however, as they are being cut off (only part of the image is being shown). I am using Canvas objects to hold the images. I was able to throw in a few lines to fix most of the problems, but since it isn't perfect, I'd like to get to the bottom of it. The only noticeable problem left is that if you load a vertical picture, there is space left to the right of the image that is counted as part of the canvas. I uploaded the Python code and an image which demonstrates the problem. http://www.nabble.com/file/p26012393/ForUpload.py ForUpload.py http://www.nabble.com/file/p26012393/DSC_1108.JPG DSC_1108.JPG -- View this message in context: http://www.nabble.com/Grid-Geometry-Manager---ImageTk.PhotoImage-tp26012393… Sent from the Python - tkinter-discuss mailing list archive at Nabble.com.

Getting Tix to work on Win32?
by Joe Veldhuis Oct. 23, 2009

Oct. 23, 2009

Hello to all! I'm working on a project that uses the Tix widgets pretty heavily (the tixGrid widgit is pretty much the centerpiece of the whole thing). It's going great on Linux, but now I need to get it running on Windows. The instructions for building Tix and its Python extension on Win32 are confusing and appear to be outdated, so can anyone who's done it recently tell me where to start? My Win32 dev machine is running WinXP-SP3 with Python 2.6.3 and Cygwin 1.7. MSVC is not installed at present but I have access to Visual Studio 2008 if I need it. Thanks, -Joe

Newbie question - displaying data
by MickSulley Oct. 20, 2009

Oct. 20, 2009

Hi, I am new to TKinter and struggling somewhat. I have a Python program that reads a number of temperatures from sensors in tanks and pipework, that is working fine. I now want to display those temperatures, ideally a simple diagram of the pipework with boxes displaying the values. I don't need any user input, it just runs forever once started My initial thought was to use a text widget for the whole page and update the areas that show the values. Is that the best way to do it? Can anyone give me some pointers on constructing the program? Thanks Mick -- View this message in context: http://www.nabble.com/Newbie-question---displaying-data-tp25960335p25960335… Sent from the Python - tkinter-discuss mailing list archive at Nabble.com.

Execute Python callback from Tk widgets
by Kevin Walzer Oct. 8, 2009

Oct. 8, 2009

Hi all, I'm running into some difficulty in wrapping a Tk widget from Python in a way that will allow me to execute Python callbacks/commands. I'm trying to incorporate widgets from TclMacBag (http://tclmacbag.autons.net/) into one of my Tkinter programs. Specifically, I'm trying to use the "stylebutton" widget. At their base, the TclMacBag stylebuttons are just ttk::buttons with a custom style. However, they are constructed as megawidgets, their internal API is quite complex, and so getting at their underlying button and style implementation from Tkinter is difficult. My current approach is to define a simple Tcl/Tk package that exposes the functionality I need, and then use self.tk.call() to access this from Tkinter. Here's an abbreviated example: ##Tcl code in "macstylebutton" package proc macstylebutton {w child img cmd layout msg row column } { ::tclmacbag::stylebutton $w.$child -image $img -style $layout -command $cmd grid $w.$child -row $row -column $column balloon $w.$child $msg } #Python function def styleButton(self, parent, child, img, cmd, style, msg, row, column): self.tk.call('package', 'require', 'macstylebutton') self.tk.call('macstylebutton', parent, child, img, cmd, style, msg, row, column) #Python GUI code that calls the function self.deletebutton=self.styleButton(self.topframe, 'delete', self.logout, lambda: self.authorizeCommand(self.deletePackage), 'mail', 'Delete package', 0, 2) This code lays the buttons out correctly, but the Python callback is not executed. It seems to be correctly set up; running "print cmd" yields output like this: <bound method phynchronicityApp.infoPackage of <__main__.phynchronicityApp instance at 0x3f1af8>> but the actual callback doesn't fire. My theory as to the problem is this: it appears that the widget is responding to the "cmd" parameter as a Tcl command, and since it's actually a Python command, nothing's happening. I know Python/Tkinter can execute Tcl commands through 'call' or 'eval,' but it doesn't appear that Python commands can be passed to raw Tk widgets. Indeed, I had tried to simply configure the buttons via something like 'self.deleteButton.configure(command=foo'), but Tkinter returned an error--something about a NoneType object lacking a 'configure' method. My question is this: how can I get Python callbacks to fire when a raw Tk widget is being called via 'self.tk.call'? Do I have to write a fancy wrapper that turns the widget into a Python object that will respond to Python callbacks, or is there a simpler way to do this? Thanks, Kevin -- Kevin Walzer Code by Kevin http://www.codebykevin.com

Tkinter on OS X wont import
by Nessuss Oct. 4, 2009

Oct. 4, 2009

Hi, I've been trying to work with some python programs that use Tkinter in them but when python tries to import the Tkinter package I get this error: <code> import Tkinter File "/opt/local/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/lib-tk/Tkinter.py", line 38, in <module> import _tkinter # If this fails your Python may not be configured for Tk ImportError: dlopen(/opt/local/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/lib-dynload/_tkinter.so, 2): Library not loaded: /opt/local/lib/libX11.6.dylib Referenced from: /opt/local/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/lib-dynload/_tkinter.so Reason: no suitable image found. Did find: /opt/local/lib/libX11.6.dylib: mach-o, but wrong architecture </code> I can't seem to figure out the problem, some time ago I installed using macports tcl and tk, everything was working then. But now it gives the above error. In between the time Tkinter was last working and now I did upgrade to Snow Leopard. If anyone can help me out here, that would be great. -- View this message in context: http://www.nabble.com/Tkinter-on-OS-X-wont-import-tp25725811p25725811.html Sent from the Python - tkinter-discuss mailing list archive at Nabble.com.

Oct. 2, 2009

Dears,: I use canvas to make animation by continuously displaying objects. Now I want to export what is displayed in canvas to an image file(.bmp, jpeg,png,... is OK) Is there such function in tkinter and how can I attain this? Thank you very much!
