Re: Using a TextView as a sort of "Hbox with wrapping"

Chris, If I interpret what you are trying to do correctly (not necessarily a given), then I would have thought that GtkScrolledWindow (possibly in conjunction with GtkViewport) would be the tool for the job. James On 26 January 2014 14:50, Chris Angelico wrote: > My application has a status

Another possibility would be to use g_object_set_data to give the renderer a column number, and g_object_get_data in the handler. On 2 June 2013 07:15, dE wrote: > On 06/02/13 00:27, Arnel A. Borja wrote: > >> On Sunday, 02 June, 2013 01:44 AM, dE wrote: >> >>> I've set the "editable" property

Floating point exception in functions called from gtk_main_iteration_do

I have a clock application written using gtk and cairo in Fortran (via gtk-fortran) that demonstrates many of the features of using gtk & cairo from Fortran. For historical reasons it uses a home-made event loop with a poll for events and a wait. Unfortunately now when using Gtk3.6 and building t

Hello, I'm working on some aspects of gtk-fortran (an interface of GTK+ to Fortran95/2003), and so need to implement things without using varargs routines. However I'm getting unexpected behaviours. I don't think the problem is in the Fortran interface as I can reproduce the errors in C-examples.
