Hi, When the ‘row-activated’ signal gets fired in a TreeView, either by pressing Enter or double-clicking, the selection gets reduced to the currently focused row, i.e. any other rows that were previously selected get deselected. Is there some way to avoid this, so I can get the list of selected rows in the row-activated handler? PyGTK supports this directly by passing a list of selected rows to the handler, but it looks like in Ruby-GTK this isn’t possible for some reason. Cheers, Markus * * * Take Surveys. Earn Cash.

What about the following script: #!/usr/bin/env ruby require ‘gtk2’ window = Gtk::Window.new model = Gtk::TreeStore.new(String) tree\_view = Gtk::TreeView.new tree\_view.model = model tree\_view.selection.mode = Gtk::SELECTION\_MULTIPLE prev\_selected = [] selected = [] tree\_view.selection.signal\_connect(“changed”) do |selection| prev\_selected, selected = selected, selection.selected\_rows false end tree\_view.signal\_connect(“row-activated”) do |widget, path, column| p prev\_selected false end cell = Gtk::CellRendererText.new column = Gtk::TreeViewColumn.new(“column”, cell, “text” =\> 0) tree\_view.append\_column(column) 10.times do |i| iter = model.append(nil) iter.set\_value(0, i.to\_s) end window.add(tree\_view) window.show\_all Gtk.main > ``` > PyGTK supports this directly by passing a list > > ``` > > of selected rows to the handler Really?

Hi (sorry for the broken thread, I wasn’t subscribed to the list yet) > > PyGTK supports this directly by passing a list of selected rows to the handler > > Really? Could you show me a example for that? You’re script does the trick, though it doesn’t work when double-clicking, and it doesn’t restore the selection afterwards. But after rewriting it in Python I realized that PyGTK has the same behaviour. The reason I assumed PyGTK handles this is that I saw it in the code of the Python music player Quodlibet, but I just now realized that they use a custom TreeView which implements that behaviour (see the MultiDragTreeView in [http://www.sacredchao.net/quodlibet/browser/trunk/quodlibet/qltk/views.py](http://www.sacredchao.net/quodlibet/browser/trunk/quodlibet/qltk/views.py)). So, I guess I’ll try to rebuild that class in ruby. But thanks for your answer, anyway! Here’s the python version of your script: #!/usr/bin/env python import gtk window = gtk.Window() model = gtk.TreeStore(str) tree\_view = gtk.TreeView(model) tree\_view.get\_selection().set\_mode(gtk.SELECTION\_MULTIPLE) prev\_selected = [] selected = [] def changed(selection): global prev\_selected, selected prev\_selected = selected model, selected = selection.get\_selected\_rows() tree\_view.get\_selection().connect(“changed”, changed) def row\_activated(widget, path, column): global prev\_selected print prev\_selected False tree\_view.connect(“row-activated”, row\_activated) cell = gtk.CellRendererText() column = gtk.TreeViewColumn(“column”, cell) column.add\_attribute(cell, “text”, 0) tree\_view.append\_column(column) for i in range(0, 10): model.append(None, row=[str(i)]) window.add(tree\_view) window.show\_all() gtk.main() Cheers Markus * * * Take Surveys.
