No problem. :-)
The gtkhs@haskell.org mailing list was for the now defunct GTK+HS project. The successor project which it looks like you've been using is Gtk2Hs.
It's mailing lists are listed here: http://haskell.org/gtk2hs/development/#mailing_lists
So you'd want gtk2hs-users@lists.sourceforge.net
Thanks you very much for the links. I`m sorry I do not know that.
Hi, i'm making my first graphic interface program with Haskell. I use Glade and Gtk+2.0. I create an empty comboBox with Glade and I want to add items (strings) in run time (by means of the haskell code). I tried with the functions 'comboBoxAppendText' and 'comboBoxInsertText' (http://haskell.org/gtk2hs/docs/current/Graphics-UI-Gtk-MenuComboToolbar-Comb...) but I can not do anything for display the information I want. This functions require to work with a comboBox creates with the constructor comboBoxNewText (and I think this constructor is not the used by Glade).
I can create it from Glade?
Sadly not, in Glade it allows you to create a general ComboBox. The comboBoxNewText convenience functions can only be used in the code, not from Glade.
I can do I want by another method?
So there are two things you can do. One is to use the general interface which means creating your own model which will hold the data you want to display. If you want to display anything more complex in the combo box than simple strings then this is the only method to choose.
However I just realised that with the current Gtk2Hs releases we didn't bind quite enough functions for you to use a non-trivial model with a ComboBox. We'll fix that for the next release.
So as Piotr suggested, you should create the combobox in code with comboBoxNewText rather than in glade and then that to the right place in the gui constructed with glade.
For example:
box <- xmlGetWidget xml castToBox "box1" combo <- comboBoxNewText containerAdd box combo widgetShow combo
Thanks you, it lack me the 'containerAdd' function.
I'd like to note that the next release of Gtk2Hs will make it much much easier to create data models to use with views like the TreeView and ComboBox.
