There's a tutorial here:
http://liw.iki.fi/liw/texts/gtktreeview-tutorial.html
Don't forget the examples that come with the pygtk distribution. I whipped
up my own example of a multi-column treeview. It demonstrates a few things:
* How make certain cells editable. Here I use two "control" columns
at the end of my row (store column 2 & 3) that control whether a cell
is editable and visible. How the renderer uses these columns is set with
column = gtk.TreeViewColumn(column_titles[i], cell, text=i,
editable=ncols+i, visible=ncols+i)
which means that the renderer will get the text to render from column i
and determine whether the cell is editable and visible using the
values in column ncols+i. See the properties for the different
renderers to see what other keywords you can use.
* A callback for the "edited" signal which actually sets the new text
that you type in a cell. I use set_data/get_data to retrieve the
actual store column that the renderer corresponds to (you could also
pass it as user_data when connecting the callback).
* How to get a selection, this is in the on_delete_button_clicked callback.

[pygtk] GtkTree documentation
Hi, all. Is there any documentation or examples that show how to use the new GtkTree code in python? Especially with a libglade generated interface? A working tree example would be ideal. Thanks, Colin -- Colin Fox <[EMAIL PROTECTED]> CF Consulting Inc. signature.asc Description: This is a digitally signed message part ___ pygtk mailing list [EMAIL PROTECTED] http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://www.async.com.br/faq/pygtk/
[pygtk] GtkTree{Model,Store} API additions in PyGTK.
This email describes the API additions that have been made to the
GtkTreeStore and GtkListStore classes in PyGTK in order to make them
more friendly to Python programmers. It is cc'd to the GTK# mailing
list at the request of one of the developers, but should mainly be
useful to Python programmers.
The description below is of what is currently in CVS. Most of the
functionality is in released versions, but some is recent.
There is no special wrapper for GtkTreePaths in PyGTK. Since a tree
path is really just an ordered list of indices, we represent them as
tuples of integers. In places where a GtkTreePath must be passed to
GTK, the following Python types will be accepted:
* strings: these get parsed by gtk_tree_path_new_from_string(). The
syntax is like "1:2:3:4".
* tuples of integers: as described above.
* integers: treated as a path of length one. Useful for
GtkListStores, as will become apparent.
By accepting integers as length-one tree paths, the user can just pass
in integers for GtkListStore methods, and think of them as row numbers.
They don't even need to think about paths.
Sequence/mapping behaviour: GtkTreeStore and GtkListStore implement the
__getitem__/__setitem__ API. You pass in a tree path as a key and get a
"row object" as the value. The row object basically combines a pointer
to the tree model and a GtkTreeIter for the row. It in turn looks like
a sequence -- one item per column in the model. You can get and set
columns in the row through this interface. The best way to explain this
is with some examples:
liststore = gtk.ListStore(str, str, int) # create list store
treestore = gtk.TreeStore(int, str, str) # and a tree store
... # fill in some rows
row = liststore[42] # get the row object for the 42nd row in the list
print row[2] # print 3rd column in row
print liststore[42][2] # or the two operations can be combined
# print first column of first child of the second top level node
print treestore[1,0][0]
# assignment works too
liststore[42][2] = 42
# you can also assign to the entire row in one go
treestore[1,0] = (5, 'foo', 'bar')
# or delete rows
del liststore[42]
If you have a GtkTreeIter for a row, you can also get the corresponding
row object for it with "store[iter]". As well as looking like a
sequence, row objects have the following attributes:
* next: next sibling row object
* parent: parent row object
* model: the GtkTreeModel for this row
* path: the tree path of this row.
* iter: a GtkTreeIter pointing at this row.
Iteration: tree and list stores implement the Python iteration API.
This means that you can easily do things like print the value of the
first column for every row in a list store:
for row in liststore:
print row[0]
For tree stores, this only iterates over the toplevel of the tree. Each
row object has an iterchildren() method that can be used to iterate over
the child rows if desired (if you directly iterate over the row, you
will get the columns).
Extra optional argument on append/prepend/insert methods: I added an
additional optional argument to the insert, insert_before, insert_after,
prepend and append methods. If passed, the additional argument is
interpreted as a sequence of values of the columns in the new row. For
instance:
liststore.append(('foo', 'bar', 42))
This makes the list store feel a lot more like the standard Python list
objects.
James.

[pygtk] GtkTree problem
I'm trying to create and app that displays two db related trees and be
able to select for addition insertion and moving stuff around.
I've browsed the faq's the tree examples and I've gotten to the point
where I've created the widget with glad and I see two empty trees just
waiting to be filled up.
I'm trying to implement a method that will fill a tree by giving the
method the window instance ,the tree (text)I'm talking about and a
dictionary containing the data I want to show.
So I'm using
mytree(self.w,t,sons)
Let's take a look at mytree's constructor
def __init__(self,win,tree,sons):
print "win is %s tree is %s"%(win,tree)
combined="%s.%s"%('win',tree)
twin=eval(combined)
print twin
the output I get when I print twin is:
now all methods I try to use like connect ,append etc... are returned
with an error:
AttributeError: 'GtkObject' object has no attribute 'append'
The docs and examples do the connects and appends at this stage so I'm a
bit confused.
Anyhelp will be realy appriciated.

in some cases, GtkTree stops redrawing correctly (and the expanders stop
working when this happens), and the GtkTree widgets don't really act like
widgets when they are not the root of the tree.

Modify your gtkrc file so that the bg[PRELIGHT] for the style applied to
CTrees widget.
Programatically, this would be something like:
style = ctree.get_style().copy()
style.bg[STATE_PRELIGHT] = ctree.get_colormap().alloc('white')
ctree.set_style(style)
But this will make things look weird in some themes, so it is usually
better to modify the theme colours.

You can use the set_subtree() method of the tree item to specify a GtkTree
as a subtree. I don't recommend using GtkTree though, as it is fairly
broken.
The CTree widget can do everything Tree does, and is less broken.

Not yet.

Re: [pygtk] GtkTree?
GtkTree is broken use GtkCTree which is crap but at least works.
If you relly must use GtkTree here is a trivial example which shows that
dnd is broken
#!/usr/bin/env python
from gtk import *
from GDK import *
class myTree(GtkTree):
def __init__(self):
GtkTree.__init__(self)
self.targets = [('text/plain', 0, -1)]
self.createTreeItems(self)
aSubTree = GtkTree()
self.children()[2].set_subtree(aSubTree)
self.createTreeItems(aSubTree)
def createTreeItems(self, aTree):
for i in range(4):
aTreeItem = GtkTreeItem("tree item " + str(i))
aTree.append(aTreeItem)
aTreeItem.drag_dest_set(DEST_DEFAULT_ALL, self.targets,
ACTION_COPY | ACTION_MOVE)
aTreeItem.drag_source_set(SHIFT_MASK | BUTTON1_MASK,
self.targets, ACTION_COPY | ACTION_MOVE )
aTreeItem.connect('drag_data_get', self.dndDragDataGet_cb)
aTreeItem.connect('drag_data_received',
self.dndDragDataReceived_cb)
aTreeItem.show()
def dndDragDataGet_cb(self,w,context,selection_data,info, time):
dnd_string = "hello world"
selection_data.set(selection_data.target, 8, dnd_string)
def dndDragDataReceived_cb(self,item, context, x, y, data, info, time):
if data and data.format == 8:
msg = "Drop data of type %s was:\n\n%s" % \
(data.target, data.data)
print msg
if __name__ == '__main__':
gtkWindow = GtkWindow(WINDOW_TOPLEVEL)
gtkWindow.connect("destroy", mainquit)
gtkWindow.add(myTree())
gtkWindow.show_all()
mainloop()
nb show_all is broken for gtkTree so you have to call show all over the
place
There is probably a better example in the testgtk.py stuff. (hmm I just
looked and couldn't see one)
If your building your tree from something which is tree like (such as a
file system or DOM) than the easyist way is with a recursive function. The
only examples I have of this are in C so I didn't bother including them.
A word of warning if you use GtkCTree it gets very confused if you set a
node as branch and then don't add any leaves to it or vica verca.

[pygtk] GtkTree?
I am trying to build a simple tree using the following code:
mytree = GtkTree()
myitem = GtkTreeItem("something")
mytree.append(myitem)
my question is, how to actually build the nodes and leafelets... I have the
GTK reference but it is in C and I had given up on C 10 years ago so it is
pretty greek to me. Any help on any functions or classes I am overlooking
would be appreciated. I tried tinkering with GtkTreeItem.set_submenu to no
avail.
Thanks for your help.
Another quick question. Is there an actual reference for the python GTK
wrapper?

[pygtk] GtkTree
Hi, I am have been playing with GtkTree for a while now and I cant seem to figure out how to get the Tree to show in collapsed mode. Because if you create all the trees they are automatically expanded, and I dont want that effect. Does anyone have any code that I can look at where people used GtkTrees. Thanks, any help will be appreciated. - Lex - To unsubscribe: echo "unsubscribe" | mail [EMAIL PROTECTED]

I remember there was an exemple of GtkTree in a forwarded email some weeks ago. I lost it. Can send it again?
