winfo_width problem
by evgeny fadeev Oct. 1, 2005

Oct. 1, 2005

Hi, i am trying to use winfo_width to determine widget's size and it always returns me 1 regardless of wheter widget is packed/gridded or not. in native Tcl/Tk winfo width .widget works fine, i.e. returns actual width in pixels direct tk call from python tk.call('winfo','width',widget._w) still returns 1 i guess it points to some bug in tkinter ...... what do you think? Thanks. Evgeny. _________________________________________________________________ Express yourself instantly with MSN Messenger!

Some progress, some troubles with BWidget tree
by gilcneth＠earthlink.net Sept. 19, 2005

Sept. 19, 2005

Hello All: I finally figured out what was wrong with my code before, with regard to creating new nodes (please see code below). My difficulty now is understanding how to work with focus. I am able to generate nodes and I am able to identify them by their position. Now, I am trying to identify nodes that have focus. But, perhaps my thinking is wrong? Essentially, I am trying to identify the node(s) that the user has selected, so that only certain events can occur when those nodes are highlighted/selected/have focus - ?. For example, if a parent is 'selected' or 'has focus', the end-user can create other parents AND/OR additional children, but if a child is 'selected' or 'has focus', only additional children can be created. I have tried the 'focus' function in varying combinations, but I'm always returning 'None' or an instance-error. Any suggestions here are quite welcome. I am beginning to understand things a bit better now, but 'global'-? BWidget functions are not one of these things. Thank you and Best Regards, Chris Nethery ############ file tree_example.py ############################## import Tkinter as tk import bwidget as bw import string class DirTree(tk.Frame): def __init__(self, master, *args, **kw): tk.Frame.__init__(self, master) treeFrame = tk.Frame(master) treeFrame.pack(side=tk.TOP) self.tree_Instance = tree_Instance = bw.Tree(treeFrame, padx=60, opencmd=self.open_node, closecmd=self.close_node, *args, **kw) tree_Instance.pack(fill='both', expand=1) self.tree_icon = tk.PhotoImage(file=tree_icon.gif') self.parent_icon = tk.PhotoImage(file='parent_icon.gif') self.child_icon = tk.PhotoImage(file='child_icon.gif') self.node = tree_Instance.insert('end', 'root', text='Sample Tree', image=self.tree_icon, drawcross='allways', data='/') tree_Instance.opentree(self.node, recurse=0) buttonFrame = tk.Frame(master) buttonFrame.pack(side=tk.BOTTOM) self.creat_Nodes_Button = tk.Button(buttonFrame, text='Create Nodes', command=self.create_nodes, relief=tk.GROOVE) self.creat_Nodes_Button.pack() def close_node(self, node): self.tree_Instance.itemconfigure(node) def open_node(self, node): path = self.tree_Instance.opentree(node, recurse=1) def create_nodes(self): parent_0 = self.tree_Instance.insert(0, 0, text='1st Parent', image=self.parent_icon, drawcross='allways') child_0_0 = self.tree_Instance.insert(0, parent_0, text='1st Child', image=self.child_icon, drawcross='allways') child_0_1 = self.tree_Instance.insert(1, parent_0, text='2nd Child', image=self.child_icon, drawcross='allways') child_0_2 = self.tree_Instance.insert(2, parent_0, text='3rd Child', image=self.child_icon, drawcross='allways') parent_1 = self.tree_Instance.insert(1, 0, text='2nd Parent', image=self.parent_icon, drawcross='allways') child_1_0 = self.tree_Instance.insert(0, parent_1, text='1st Child', image=self.child_icon, drawcross='allways') child_1_1 = self.tree_Instance.insert(2, parent_1, text='2nd Child', image=self.child_icon, drawcross='allways') child_1_2 = self.tree_Instance.insert(3, parent_1, text='3rd Child', image=self.child_icon, drawcross='allways') widget_List = [ parent_0, child_0_0, child_0_1, child_0_2, parent_1, child_1_0, child_1_1, child_1_2, ] for w in widget_List: print self.tree_Instance.index(w) print 'But I cannot seem to "find" focus. : ) Focus = ' + str(self.tree_Instance.focus()) def test(): r = tk.Tk() t = DirTree(r, bg='white', selectbackground='blue4', selectforeground='white', deltax=60, deltay=45, width=50) t.pack(fill='both', expand=1) r.mainloop() if __name__== '__main__': test() ############################################################## gilcneth(a)earthlink.net

BWidgets Tree
by gilcneth＠earthlink.net Sept. 16, 2005

Sept. 16, 2005

Hello Everyone. I am working with the BWidgets tree, but am having difficulty understanding how Parent/Child node relationships are actually handled. More specifically, I think that most people use Trees to REPRESENT hierarchies?...I would like to use the widget to CREATE them. Having said this, the BWidget Tree looks like it is probably the best tree widget for this purpose. But, like os.listdir is doing in Michael Lange's program, I need to generate and cache lists reflecting the contents of each parent node. Anyway, if you run the program I have included (you'll have to use other icons), I am (so far) able to generate Child-nodes. Now, I want to be able to create 'GrandChildren' from whichever node has focus (need to add highlighting later). I also want to keep track of each node's level in the hierarchy because the level of the node will determine which icons will be used, not its 'state' (ie. open or closed). I think I should be able to do this just fine, once I can gain access to the Parent nodes' names and the Child index positions. However, when I try to grab index positions, parent-names, etc., I am receiving errors because I am trying to grab data from the widget instances, rather than the widgets themselves. If I seem excessively confused, I hope you'll forgive me. It takes me a few nudges in the right direction before I start to catch on to things like this. import Tkinter as tk import bwidget as bw class DirTree(tk.Frame): def __init__(self, master, *args, **kw): tk.Frame.__init__(self, master) treeFrame = tk.Frame(master, height=200, width=200) treeFrame.pack(side=tk.TOP) self.tree = bw.Tree(treeFrame, opencmd=self.open_folder, closecmd=self.close_folder, *args, **kw) self.tree.pack(fill='both', expand=1) self.data_element_icon = tk.PhotoImage(file='C:\Documents and Settings\John Doe\Desktop\Test_Icon.gif') self.node = self.tree.insert('end', 'root', text='/', image=self.data_element_icon, drawcross='allways', data='/') self.tree.opentree(self.node, recurse=0) buttonFrame = tk.Frame(master, height=200, width=200) buttonFrame.pack(side=tk.BOTTOM) self.button = tk.Button(buttonFrame, text='Create child node', command=self.create_node, relief=tk.GROOVE) self.button.pack() def close_folder(self, node): self.tree.itemconfigure(node, image=self.data_element_icon) def open_folder(self, node): path = self.tree.opentree(node, recurse=1) def create_node(self): if self.button: self.tree.insert('end', self.node, text='Hello There', image=self.data_element_icon, drawcross='allways') def test(): r = tk.Tk() t = DirTree(r, bg='white', selectbackground='blue4', selectforeground='white', deltax=18, deltay=18) t.pack(fill='both', expand=1) r.mainloop() if __name__== '__main__': test() Thank you and Best Regards, Chris Nethery gilcneth(a)earthlink.net

Non-Rectangular Windows Help
by Sajjad Hussain Sept. 15, 2005

Sept. 15, 2005

Hi, I am repeating this question again. I was told that there is a library available that allows you to create non-rectangular windows in Python-Tkinter (like the Windows Media Player). Can anyone please tell me if there is any other library available or how to install this. I am trying to install tkdnd and its tkinter wrapper available from these sites http://sourceforge.net/projects/tkdnd http://www.8ung.at/klappnase/TkinterDnD/TkinterDnD.html I have placed the TkinterDnD.py in the lib-Tk folder of Python. I have also unzipped and placed the tkdnd-1.0a2 (contains the demo, lib, doc folders) folder in Tcl\lib folder. There are two dlls available. They are: libtkdnd.dll and libtkdnd10.dll. I am not to sure where to place them. Now when I type the following commands, I get the error shown below: >>> from Tkinter import * >>> import TkinterDnD >>> root = TkinterDnD.Tk() Traceback (most recent call last): File "<interactive input>", line 1, in ? File "c:\Python23\lib\TkinterDnD.py", line 104, in __init__ self.tk.eval('package require tkdnd') TclError: can't find package tkdnd Can anyone please tell me what I am doing wrong. __________________________________________________ Do You Yahoo!?

pybwidget release 0.1.2
by jepler＠unpythonic.net Sept. 15, 2005

Sept. 15, 2005

pybwidget is a Python wrapper around the 'bwidget' family of widgets for Tkinter. It includes these classes: Entry Label Button ArrowButton ProgressBar ScrollView Separator MainFrame LabelFrame TitleFrame PanelFrame ScrolledWindow ScrollableFrame PanedWindow ButtonBox PagesManager NoteBook Dialog StatusBar LabelEntry ComboBox SpinBox Tree ListBox MessageDialog ProgressDialog PasswordDialog SelectFont SelectColor I know it's been a long time, but I've finally gotten around to making a new release of pybwidget, called 0.1.2_1.7.0. It has all the fixes I could find that have been mentioned in the tkinter-discuss mailing list archives. Compared to 0.1.1, here's a summary of changes: * add ROOT as a module-level constant, as requested * bindtabs, bind_image, bind_text all handle the 'func' parameter properly * several instances of 'self.tl' corrected to 'self.tk' * the 'nodes' function of the Tree widget now passes all arguments to Tk * The xbm-format images are installed by setup.py * how to run setup.py is mentioned in README.html This release is available at http://tkinter.unpythonic.net/bwidget Please report your experiences, good or bad, on the Tkinter mailing list tkinter-discuss(a)python.org Jeff Epler jepler(a)unpythonic.net

Difficulty getting started with a BWidget Tree
by gilcneth＠earthlink.net Sept. 15, 2005

Sept. 15, 2005

Hello All: I am trying to create a Tree, using PyBWidgets, but am unsure about how to actually create the initial parent and/or child nodes. The documentation leads me to believe that I should use the' insert' command, but how? The documentation indicates the following: pathName insert index parent node ?option value...? So, given my example below, if I want to add a node to my Tree, wouldn't I use the command TopTree.insert? And, if so, I assume I start at index '0'? OK, but now who's the parent? I know this has to be simple, but I am just not figuring this one out. Please share your thoughts. Thank you! -- Chris Nethery from Tkinter import * from bwidget import * t = Tk() TopTree = Tree(t, relief=GROOVE) TopTree.pack() t.mainloop() gilcneth(a)earthlink.net

Menus
by Cam Sept. 15, 2005

Sept. 15, 2005

It's easy enough, using Menubutton and Menu, to make a menu pop up in response to the user clicking a button. I want to make a menu pop up when the user right-clicks on a canvas. This seems like a kind of common thing to want to do but nothing in Tkinter or PMW is popping off the page at me as a way to do this. Am I just being really dense or is there no simple way to accomplish this? Thanks Cam Farnell
