Hi, 

I'm new to python and i'm using Tix Tree widget in my application. I'm trying to clear the tree selection but no luck so far. I tried selection_clear and anchor_clear but these aren't working. Can someone help?


Thanks,

Hey Hani,

Are you sure you are calling the selection_clear method of the hlist child
widget and not the parent tree?

eg.
tree = Tix.Tree(root)
tree.hlist.selection_clear()

If you look in Tix.py you can see that Tree is a compound widget containing
two scrollbars and a hlist.

class Tree(TixWidget):
    def __init__(self, master=None, cnf={}, **kw):
        TixWidget.__init__(self, master, 'tixTree',
                           ['options'], cnf, kw)
        self.subwidget_list ['hlist'] = _dummyHList(self, 'hlist')
        self.subwidget_list['vsb'] = _dummyScrollbar(self, 'vsb')
        self.subwidget_list['hsb'] = _dummyScrollbar(self, 'hsb')

Thus to clear the hlist selection you must address the child hlist directly
and not its parent Tree widget.

Cheers,
James

Yes, i used the hlist component of the tree but nothing happens. The thing is I can clear the selection if I use selection_set then selection_clear but i can't clear the selection when it's highlight with a mouse.

Thanks,

Does this script function as expected on your installation? You should be
able to select multiple items in the tree and then clear the selection with
the button.

Works for me on both winxp and ubuntu with 2.6trunk, 2.5maint and
2.4maintcompiled against
tcl8.4.12, tix-8.4.0, tk8.4.12. Which version of python and what tcl/tk/tix
libraries are you using?

cat hlisttest.py

from Tix import *

def clearSelection(hlist):
    hlist.selection_clear()

tk = Tk()

# create and configure tree
tree = Tree(tk)
tree.hlist['selectmode'] = EXTENDED
tree.hlist['wideselection'] = TRUE
tree.hlist['background'] = 'white'

# add a couple of tree nodes
tree.hlist.add("test1", text="Hello world")
for i in range(5):
    tree.hlist.add_child("test1", text="item%d" % i)

# add button for selection clear
Button(tk, text="Clear Selection", command=lambda:clearSelection(tree.hlist
)).pack()

# pack tree
tree.pack(expand=TRUE, fill=BOTH)

tk.mainloop()

Your script works as expected and I think the problem in my script is a conflict when importing modules. The following are modules loaded order:

from Tkinter import *
from copy import copy, deepcopy
import Tix
import tkFileDialog
import Tkinter as Tk

Is there a way i can resolve the conflict between tkinter and tix without removing tkinter?

Thanks,
Hani

Message-ID: <Pine.LNX.4.44.0708071044300.3018-100000@computo-industrial.com.mx>


Hi,

I would like to know if there is a way to trap the kill button event in a 
Toplevel window. I'm having problems with a dialog which has a "Close" 
button, but users keep closing it with the kill button (the big X at the 
upper right corner). After such a close, the application refuses to 
re-open the dialog, throwing instead an exception:

File "C:\PYTHON24\lib\lib-tk\Tkinter.py", line 1541, in wm_withdraw
   return self.tk.call('wm', 'withdraw', self._w)
TclError: bad window path name ".14221680"

My guess is that I must trap the kill event as well but I don't know how 
to do it.

I like the JPEG; it's always a treat to see how Tkinter helps folks.

I apologize for letting this request languish so long.  While I shan't
make the time now to recode your application, I believe the answer you
sought is something like this:  you probably did a

    my_label = Tkinter.Label(text = "See me?")
    my_label_instance = window_create(index, window = my_label)

(see <URL: http://effbot.org/tkinterbook/text.htm >) to insert the Label.
The return value from window_create() will be a "Tkinter.Label instance";
you can just
   
    my_label_instance.cget("text")

at that point.

Do the insert BEFORE you do disable the entry.

In fact, there are applications that rely on a pattern of

    enable the entry
    update its display
    re-disable the entry

for programmatic updates.

The Checkbutton widget

Var = IntVar()
Checkbutton(Frm, text = "Destroy", variable = Var)

wants Var to be an IntVar, but it also works if Var is a StringVar  
and you set() Var to "0" and "1".  Is there a possibility that this  
will be "fixed" some time in the future, or would it be safe to keep  
Var as a StringVar, or is it not even really broken (I don't know Tcl/ 
Tk which I assume is allowing this?)?  In my case it would be nice to  
keep "0" or "1" in a MySQL database column and have a Tkinter form  
with a Checkbutton do the right thing without having to change the  
column to an int, or keep converting back and forth between chars and  
ints for that one column to keep from running into trouble in the  
future.

Thanks!

Bob

Hi Bob,

I am not a tcler myself, but I think the integers are being converted to strings
anyway when they are passed to tcl, so 1 and "1" might be equivalent here.
If you want to be even more safe, you might want to use the checkbutton's
onvalue and offvalue options, like onvalue="1", offvalue="0" .

Subject: [Tkinter-discuss] sqlite3 operational error with tkinter
Message-ID: <12381457.post@talk.nabble.com>


Hi.

I am writing a small questionnaire application. I am using sqlite3 and
tkinter + python. I started off by writing a console application. The
application queries a db file i created . But while using in the gui
application i am getting an error that a column cannot be decoded into
UTF-8. Is this a problem with the DB file? or has this got to do something
with tkinter? I am attaching the source code too.

thanks

Subject: [Tkinter-discuss] Tix HList missing at least one method
Message-ID: <002f01c7ea76$751bdfb0$6501a8c0@aristotle>

According to the Tix documentation online, HList has an info_bbox() method which returns the bounding box of a given item in the HList.  However, when I try to call this method, I get an attribute error.  Looking at Tix.py I see that info_bbox() is not implemented.

Hazarding a chance (mostly by looking at the other method implementation) I see if I can define it myself.

def info_bbox( self, entry ):
   return [ int(pos) for pos in self.tk.call( self._w, 'info', 'bbox', entry).split() ]

When I use this implementation it works.  Why's info_bbox() been left out of HList?

I can't formulate a work-around for what I'm trying to do.  I need info_bbox().

Here's why:

I'm currently working on a project which involves some fairly complex GUIs.  It displays data in the form of an outline which the user can edit, it also generates web pages.  To allow a natural feel to editing the order of the items in the outline, I decided to make use of the Tkinter drag and drop module: Tkdnd.  To do this correctly, I need to do a bit of arithmetic with screen coordinates while in a drag operation  (so I can change the cursor during the drag) so that I can determine if my current drag position (potential drop position) is above, below or as a child of some other item in the outline.  The easiest way to do this is to get the bounding box of the nearest items.


Thanks,
Ron

onvalue?! offvalue??!!  Every time I look in Grayson's Python and  
Tkinter programming I DON'T see something. :)  I never even knew  
those existed and I must have looked at that section 100 times over  
the years.  Thanks!

I have a canvas and have to perform some action when it is resized.  How
can I get notified when resizing happened?  How do I find out the amount
of the change (without keeping the old size myself)?

I tried overriding config (configure), but it is not called during
resizing.

Thanks for any advice!

I've found that the generation of the <Configure> can also change  
from OS to OS, and from system to system with the same OS.  Tkinter  
on Windows seems to only generate the <Configure> when you are  
finished resizing (which may or may not be what you want), and some  
Linux/Solaris/OSX systems generate it (a lot) while you are moving  
the mouse (which may or may not be what you want).  I don't know how  
to change it, but I think generating the <Configure> while the mouse  
is moving may be a configuration option of X11, so you may have to  
allow for either case.

Hi Ron,

this is not much of a surprise to me, there are more things missing from the Tix module.
Probably it is the best to use your "private" Tix module with the added info_bbox() method.
If you like you can send a patch to the python developers to fix this.
BTW, maybe there is a bug in your implementation of info_bbox(), it will fail if the tcl method
returns an empty string which might happen if the named item does not exist or so. You better
use self._getints() as in Tkinter.Canvas.bbox() :

    def info_bbox( self, entry ):
        return self._getints(self.tk.call(self._w, ?info?, 'bbox', entry)) or None

I hope this helps

Michael
