If I understand your question I don't think you need to use the set_modify_func() method. The set_visible_func() method should be sufficient but you have to pass in an object that has mutable contents corresponding to the columns that you want to use for filtering. For example you could create a Python object that has one attribute that contains a list of car models and another attribute that has a maximum price. Pass this object as the data arg to the set_visible_func() method and change the attributes as needed. Your visible_cb() function could then do something like:def visible_cb(self, treestore, iter, x):return treestore[iter][0] in x.models and treestore[iter][4] <= x.maxpriceJohn
It did work!! thanks a lot jhon!!...However a new trouble has shown up!!, now i do need to get the row data from the treeview which respond to the set_visible_func() method. It is easy to get the data from an ordinary treeview, it can be done by "catching" the "cursor_changed" signal and handling it with a function as follows:
---------------------------------------------------------------------------------------------------------------------------------#the treeview is connected to the signal and this event is connected to a signal handler
self.connection= self.treeview.connect("cursor_changed", self.getreedata)
#then the signal handler (a callback) is in charge of getting the data of
the row
def self.getreedata(self, iter): treeselection = self.treeview.get_selection() select= treeselection.get_selected() row_value= self.treestore.get_value(select[1], 0) ---------------------------------------------------------------------------------------------------------------------------------where "select" is a list with two values [model, iter], then select[1] is an iter pointing to the position of the cursor in the treeview and consecuently, "row_value" is the value of the row where the cursor is positioned in the column "0" of the treeview.
This works perfectly in odinary treeviews, however when filtering (i mean when using the set_visible_func() method) i do receive the following error message:
--------------------------------------------------------------------------- File "carstreeview.py", line 11, in getreedata row_value= self.treestore.get_value(select[1], 0) TypeError = unknown type (null) ---------------------------------------------------------------------------why this does not work when filtering the treeview???, do i need to set any property to the treeview?? the code above works properly for no filtered or commom treeviews, but not when filtering...is the case that set_visible_func() avoids retrieving row values??? if so, can the data be retrieved from the treemodel??, how??, i have seen there is not "cursor_changed" signals for treemodels
any suggestion??. thanks for your help in advance juan.- _______________________________________________ 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/
