Anyone for CMake?
A couple of weeks ago I started on a build of glib/gtk+ using MSVC++. I haven't been able to devote masses of time to it but the small amount that I've done so far was refreshingly pain-free - thanks mostly to the presence of ".vcproj" files for me to work with. Sadly, the supporting libraries don't seem to be as comprehensive. Pango, Cairo, ATK etc seem to come only with makefiles, from what I can tell. ;( I guess there's a (slim) chance they'll work with Microsoft's Nmake but Nmake isn't noted for such flexibility and I assume that whatever comes with the above libs is primarily intended for Autoconf / Automake etc. I just wondered if there's ever been any discussion in the *nix community about moving away from Autoconf/Automake in favour of CMake? I guess this topic must have come up several times already, so what were considered to be the pros and cons? At first glance, CMake seems to be a lot more modern and certainly a lot friendlier towards the other major platforms, as well as *nix.

Re: cygwin gtk+ eclipse on windows Gtk-WARNING cannot open display
I'm forced to use cygwin for work so I have no choice. I solved the problem.

It seems to sum up the issue quite nicely: http://lwn.net/Articles/188693/ The discussions are interesting too.

central 'library' of self-contained real world examples of code for gtkwidgets
In veiw of the nightmare I've had finding non-trivial example code for assembling/implimenting gtk widgets recently I have decided to attempt to assemble a library of functions that impliment a task at a more advanced level than your typical 'Hello world' that abound. Some examples would be: A menubar that uses each type of GtkMenuItem - simple text, stock item, label & icon, check box, radio buttons, a button that calls a dialog, ... A 'command help' dialog, with dismiss button that uses a liststore to show command short form, long form and description. Anyone who follows this list will have seen many of these are beyond my current capabilities so I'm calling on the list to offer up some of their own little gems to make this a worthwhile resource. How about it? ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

I wish to set word-wrap for a single column in a treeview liststore, I've found the options I need to set but can't for the life of me find an example of how to do it. I think the catch is that you need to set an explicit wrap-width when specifying wrap-mode on the GtkCellRendererText. I know that, I have searched but not found anything that says "this is how you set the properties of ..." what I'm trying to do is set wrap-width to 60 characters and wrap-mode to word somewhat like this: GtkSomeObscureFunction(list->action, wrap-width = 60, wrap-mode = PANGO_WRAP_WORD); I think the obscure function you want is: gtk_container_child_set_property () (Not to cast aspersions at the developers but some of the function calls are truly convoluted, at least to someone not on the development team. On the other hand the documentation is superb.) I also wish to set alternate rows backgrounds to white or pale blue, how is this done? I don't think there is a really clean way to do this since you can't know where the line will break. My best idea is to set the textview background (using a gdk_draw_rgb_image... () call of course. How could you not know this?). Using the row stride feature it shouldn't be too hard. See the gtk examples (sudo apt-get install gtk2.0-examples) program /usr/bin/gtk-demo and the Pixbufs example. ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

To enable different background colors for alternate rows, set the rules-hint property of the view to TRUE: gtk_tree_view_set_rules_hint (view, TRUE); This will leave the color choices to the theme, which is generally what you want.

That's because both are properties of GtkCellRendererText - you just went looking in the wrong direction of the hierarchy :) Florian ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
g_io_scheduler_job_send_to_mainloop How to?
Hello,
I use g_io_scheduler_job_send_to_mainloop function for running
functiton in another thread:
void build_thumbnails(GtkWidget* widget, MainWin* mw)
{
printf("BUILD!!!");
}
I have structure for func parameters:
typedef struct _JobParam
{
GtkWidget* widget;
struct MainWin *mw;
}JobParam;
job func:
gboolean job_func(GIOSchedulerJob *job, GSourceFunc func, gpointer
user_data, GDestroyNotify notify)
{
JobParam* job_param = (JobParam*)user_data;
build_thumbnails(NULL, job_param->mw);
return TRUE;
}
And try to call:
void loading()
{
g_io_scheduler_job_send_to_mainloop(job,(GSourceFunc)job_func,¶m, g_free);
}
I get error: g_io_scheduler_job_send_to_mainloop: assertion 'job != NULL' failed
What's wrong. How can i fix it?
Thank you.

Re: g_io_scheduler_job_send_to_mainloop How to?
Hi,
the code you posted looks a little incomplete, but nevertheless I think
you got it a little backwards. From what I see, it should look more or
less like this (note: I didn't actually try to compile this):
gboolean
build_thumbnails (gpointer user_data)
{
printf ("BUILD!");
}
gboolean
job_func (GIOSchedulerJob *job,
GCancellable*cancellable,
gpointer user_data)
{
g_io_scheduler_job_send_to_mainloop (job,
build_thumbnails,
user_data,
NULL);
}
void
loading ()
{
g_io_scheduler_push_job (job_func,
(gpointer)params,
free_params,
G_PRIORITY_DEFAULT,
NULL);
}
