Hi! I want to display a tree, where each row is a python object, and another function(modify_func) retieves the correct data from this object and adds to each column.
I have written a simple example program, which achieves exactly what I want. There is just one more glitch: I cant make neither of the column sortable. So can somebody help me how can I make the second (or first) column clickable and sortable? The ready-to-use demo source can be found here: http://www.pastebin.ca/1330860 I paste here too, for future reference: #!/usr/bin/env python # example treeviewcolumn.py import pygtk pygtk.require('2.0') import gtk class TreeViewColumnExample: # close the window and quit def delete_event(self, widget, event, data=None): gtk.main_quit() return False def modify_func(self, model, iter, col, attrs): """Extract the columns of a single python object.""" # Convert the filter iter to the corresponding child model iter. child_model_iter = model.convert_iter_to_child_iter(iter) child_model = model.get_model() row_obj = child_model.get_value(child_model_iter, 0) path = child_model.get_path(child_model_iter) path_str= "-".join(str(i) for i in path) if col == 0: #first column arr = self.row[path_str][col] elif col == 1: arr = self.row[path_str][col] elif col == 2: arr = self.row[path_str][col] else: arr = "faszomat" return arr def __init__(self): # Create a new window self.window = gtk.Window(gtk.WINDOW_TOPLEVEL) self.window.set_title("TreeViewColumn Example") #self.window.set_size_request(200, 200) self.window.connect("delete_event", self.delete_event) # create a liststore with one string column to use as the model self.treestore = gtk.TreeStore(object) # create the TreeView using liststore self.treeview = gtk.TreeView() # create the TreeViewColumns to display the data self.tvcolumn = gtk.TreeViewColumn('Pixbuf and Text') self.tvcolumn1 = gtk.TreeViewColumn('Text Only') # add a row with text and a stock item - color strings for # the background self.row = {} self.row["0"] = ['Open', gtk.STOCK_OPEN, 'Open a File', True] self.row["1"] = ['New', gtk.STOCK_NEW, 'New File', True] self.row["1-0"] = ['Save', gtk.STOCK_SAVE, 'Save File', True] self.row["2"] = ['Print', gtk.STOCK_PRINT, 'Print File', False] self.treestore.append(None, [self.row["0"]]) parent_iter = self.treestore.append(None, [self.row["1"]]) self.treestore.append(parent_iter, [self.row["1-0"]]) self.treestore.append(None, [self.row["2"]]) self.filtered = self.treestore.filter_new() self.filtered.set_modify_func([str, str, str, 'gboolean'], self.modify_func, ["data"]) self.treeview.set_model(self.filtered) # add columns to treeview self.treeview.append_column(self.tvcolumn) self.treeview.append_column(self.tvcolumn1) # create a CellRenderers to render the data self.cellpb = gtk.CellRendererPixbuf() self.cell = gtk.CellRendererText() self.cell1 = gtk.CellRendererText() # set background color property self.cellpb.set_property('cell-background', 'yellow') self.cell.set_property('cell-background', 'cyan') self.cell1.set_property('cell-background', 'pink') # add the cells to the columns - 2 in the first self.tvcolumn.pack_start(self.cellpb, False) self.tvcolumn.pack_start(self.cell, True) self.tvcolumn1.pack_start(self.cell1, True) # set the cell attributes to the appropriate liststore column # GTK+ 2.0 doesn't support the "stock_id" property self.tvcolumn.set_attributes(self.cellpb, stock_id=1) self.tvcolumn.set_attributes(self.cell, text=0) self.tvcolumn1.set_attributes(self.cell1, text=2) # make treeview searchable self.treeview.set_search_column(0) # Allow sorting on the column self.tvcolumn.set_sort_column_id(2) # Allow drag and drop reordering of rows #self.treeview.set_reorderable(True) self.window.add(self.treeview) self.window.show_all() def main(): gtk.main() if __name__ == "__main__": tvcexample = TreeViewColumnExample() main() Best regards, Khiraly
