Hi you all, I am developping a python application which connects to a database (postresql) and displays the query results on a treeview. In adittion to displaying the info i do need to implement filtering facility for all the columns of the treestore/liststore model in order to allow the user an easy search method to find the desired information.
The treestore is created with information related to cars, the columns are: car_model car_year car_color car_type car_price chevrolet 1998 white sedan 5.000 US$ ford 1996 blue sedan 3.000 US$ - - - - - - - - - - - - - - - I have been able to allow filtering to only one column, an extract of my code as follows: ------------------------------------------------------------------------------------------------------------------------ #treestore creation self.treestore = gtk.TreeStore(str, str, str, str, str) self.modelfilter = self.treestore.filter_new() self.treeview=gtk.TreeView() #append treestore columns self.treestore.append(None, [self.model, self.year, self.color, self.type, self.price] #set treestore model to allow filtering by car_model column self.modelfilter.set_visible_func(self.visible_cd, self.car_model) #the function to filter the treestore def visible_cb(self, treestore, iter, x) return treestore.get_value(iter, 0) in x #self.car_model is a list of items wich change according to user needs and can be controlled by a #secundary treeview or a button this function is not explained. ------------------------------------------------------------------------------------------------------------------------ The code mentioned above does work but i can only fllter by defining criterias in the first column. To allow filtering to all the columns i do need the following code to work: ------------------------------------------------------------------------------------------------------------------------- treemodelfilter.set_modify_func(types, func, data=None) def func(model, iter, column, user_data) ------------------------------------------------------------------------------------------------------------------------- where types should be: types = (str, str, str, str, str) the function to allow filtering: def visible_cb(self, treestore, column, iter, x) return treestore.get_value(iter, column) in x and the rest of the code never changes...however it is not woking. Any suggestion about the code mention?? am i making mistakes?? where?? do i have to pass the column number someway to the visible_cb function??? how?? can any of you suggest a code example to follow and find out how the treeview must be coded in order to allow "multicolumn filtering"??? thanks in advance for your support..
