[pygtk] question abt editable text in treeview
Hello All, I have a treeview with all editable columns in my app. It gets very frustrating when, for example, I have a row selected and I click on every cell in that row and the editing starts for that cell. What I want is that when I click on a cell, I dont want it to go into the editing mode, if another cell is already in the editing mode. I just want this other cell to come out of the editing mode (as if I had clicked on a different row). Then I should have to click on the new cell again to begin editing. Ofcourse if there is no cell in editable mode, then clicking on anycell should immediately put it in editable mode. Any suggestions?

[pygtk] Need help with Tree/List view
Hello All, I am currenly using the gtk TreeView to display text (simple and markedup), pixbufs, dropdown list and editable text in my application. Not all the columns are editable. Lets say the 1st, 4th and 7th columns are editable and others (besides the dropdownlist) are not. Now my question is. How do I indicate to the user which cell in the row is editable. If he/she has selected a particular row, then there is no clear indication that the particular cell he/she has clicked on or has navigated to, can be edited. Is there a way to select/highlight one cell at a time ( like in a spreadsheet )?? By default it draws a box around the text of the editable cell (due to the editable mode) while moving from cell to cell, but this box is not visible because the row higlight color is dark enough to hide it. Any suggestions ??? Hussein Vastani ___ pygtk mailing list pygtk@daa.com.au http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://www.async.com.br/faq/pygtk/
[pygtk] app freeze problem
Hello All, In my program I have gobject.io_add_watch waiting on a receive socket and a callback passed to it as parameter which gets called when ever some data arrives on that socket. Now the problem is that the data is arriving at a very fast rate. say 60 to 100 times a second. My callback gets called successfully and in my callback I parse this data and display it on a treeview ( using store.set_value() method ). My callback is not long and computational but my treeview does not display the data and my application becomes unresponsive. Any suggestions on handling this scenario? I tried handle_pending_events but that did not help much ( i guess coz i have soo many io events pending ) Any help is appreciated Thanks Hussein Vastani ___ pygtk mailing list pygtk@daa.com.au http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://www.async.com.br/faq/pygtk/
[pygtk] Zooming Text on Canvas
Hello All,
I cant figure out a way to Zoom text on a canvas
I have CanvasItems like CanvasLine, CanavsPixbuf and CanvasText on my canvas
and with the canvas.set_pixels_per_unit(..) method, all but CanvasText zoom
ok.
Is there is any reason why my CanvasText does not zoom ?
BTW my Canvas is not in antialiased mode and this is how I add my text to the
canvas.
text = self.root().add(gnomecanvas.CanvasText,
fill_color='black')text.set_property('anchor',
gtk.ANCHOR_WEST)
text.set_property('size-points', 15.0)
text.move(x_loc,y_loc)
text.set_property('text', "MYTEXT")
Any help will be appreciated
Thanks

[pygtk] Question abt sudo and password
Hello All, In my application, I run external programs by running a shell using subprocess.Popen and then writing commands to it (like 'ls -la') and reading output from it which I then display it on the screen. It works fine as long as the external program does not need to run as sudo (like tethereal), in which case, I need to provide the password to it (on the konsole). I tried looking at the gksu module. Using the gksu module I can instantiate its Context class and then call the sudo_run() method after setting the command and the password in the Context instance. That works fine but is not the approach I want to take since I want to run commands and read their ouput back. So sticking to my use of Popen to execute commands, and assuming I have a way to get the sudo password from the user via a Dialog box, how do I then exectue my command without it asking me a password on the konsole? I would not like to modify the /etc/sudoers file. Is there any other approach? Any help is appreciated Thanks Hussein Vastani ___ pygtk mailing list pygtk@daa.com.au http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://www.async.com.br/faq/pygtk/
[pygtk] CellRendererCombo Question
Hello All,
Does anyone know if something like the wrap_width function is implemented for
the CellRendererCombo in pygtk?
Heres the scenario.
I populate my combobox (in my treeview) dynamically and want to display it in
more than one column if the list is large.
This is how I set it up :
model = gtk.Liststore(str)
tree_store_col = 0
cell_renderer = gtk.CellRendererCombo()
cell_renderer.set_property("model",model)
cell_renderer.set_property('text-column', 0)
cell_renderer.set_property('editable', True)
new_col = gtk.TreeViewColumn(col_name, cell_renderer, text=tree_store_col)
tree.append_column(new_col)
cell_renderer.connect('editing-started', populate_combo, (tree_store,))
And this is how I populate the combobox in the populate_combo callback
def populate_combo(self, cell, editable, path, data):
store = data[0]
iter = store.get_iter(path)
items = self.get_list() # my function get_list() returns a list of strings
m = cell.get_property('model')
m.clear()
items.sort()
for s in items:
m.append([s])
so if my items list is large, it gets frustrating to scroll the entire list to
get to the required item. It would be nice if the items were displayed in more
than one column (for eg.)
Any suggestions on how to make this better?
Thanks
Hussein Vastani

[pygtk] Question about row selection in treeview/listview
Hello all, I have a treeview in my application and I'm trying to figure out how to 'select' individual cells in the treeview. By 'select', I mean either a) That particular cell gets highlighted, or b) The entire row gets highlighted but the particular cell that I am interested in has a different background color ( other than the blue ), or a thick border Other option (since Im not clear abt how to implement any of the above), that I tried is setting the mode of the cellrenderer to gtk.CELL_RENDERER_MODE_ACTIVATABLE, but i can see that the cell gets activated ONLY when i use my keyboard and not when I click the cell with my mouse. Bottom line is that I am trying some way to show the user that he/she has selected a particular cell in the tree view. Im sure someone mustve implemented the above or some variant of it to achieve the same purpose. Can you give me some ideas on its implementation in pygtk Any help is appreciated Vastani ___ pygtk mailing list pygtk@daa.com.au http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://www.async.com.br/faq/pygtk/
RE: [pygtk] question about handle pending events
Thank you for your reply Philip The cancel flag is what I really want to avoid because my initialization callback calls many functions within itself that return True/False for their own purpose and which may or maynot call main_iteration().

[pygtk] question about handle pending events
Hello, Ok so i read that if I have while gtk.events_pending(): gtk.main_iteration(False) inserted at the right places in my callback (which can be long computational ), my application would look response since it will get an opportunity to handle other user events while completing the callback. Consider a case where the user clicks on a button which opens up another window and does some initialization like populating three different huge tree stores and updating displays. I call main interation within this initialization code and everything looks good. But what if the user tries to close the window while the initialization callback is being executed. It will handle the destroy event and when it comes back to finish the initialization callback, the window does not exist anymore and things start crashing. I really want to keep my applicaition single threaded. Has anyone come across such a problem ? How do i stop the callback from finishing its execution when the destroy event is handled. Or. How do I peep into the event stack to see if there is any destroy-event pending to be handled ( so i dont call the main_iteration that time ). These are some ideas but they look hackish for me.

So every time a user selects a single or multiple rows, my handler 'x' is called and i know the selected rows. But what I also want to know if the control button was pressed when the click(select) was made.
