Needless to say that our Ruby combo box renderer example also does not work. The image on the left is what we get on the screen. Of course it is incorrect; there should be combo boxes in column Count. Note also that data type for this column is Integer, and that we need to convert the strings from the combo box to integer values before we could update the tree store.

+Contrary to the situation with earlier Gtk2 and Ruby versions, with Gtk2 2.24.10-3 and Ruby 1.9.3 the example below works.

Just like with the pixbuf renderer example there is a problem with the spin button renderers, you can see this from the image on the the left, where we would expect spin buttons in the Count column. Obviously there is again a problem in GTK+. As of Ruby 1.8.6 and Ruby-GNOME2 rel.: 2-0.17.0-rc1, {{image_right("dialog-warning.png")}} most of the methods in Gtk::CellRendererSpin class do not work as expected. It also looks that this is a combined C GTK+ as well as Ruby GTK+ problem. I have compiled the C example from Andrew Klause's book, and it exhibits exactly the same problems as my Ruby translation. You may check it out by clicking on (())

+With Gtk2 2.24.10-3 and Ruby 1.9.3 the example below works if the CellRendererSpin renderer is set to editable

-The dialogue in the following listing will handle the creation of a new folder in the current folder entered  into the name field and confirmed by the user, so you do not have to take any further actions except destroying the dialogue. Note, however, that there exists already a built in button (2) solely for folder (directory) creation, and that the way it is done in this program may be confusing to the user. The two fields namely the name field where a user is expected to enter a new folder name (1) and the field that opens when he or she clicks the button "Create Folder" (2) are internally related. (There may be a problem using the  button (#2) -- see the comment in the source code). Not that it is important, but this is not immediately apparent and takes some testing to realize that created folder shows up in the name field if you back up to the folder in which the new one was created. This exercise is useful only to show you the use of file chooser's action flag Gtk::FileChooser::ACTION_CREATE_FOLDER. You have to test run this program to understand what was just said!
