[Libvisual-devel] VisUI GTK2 widget, more!

[Dennis S. <sy...@yo...>]

Heya list,

Alright, I've been hacking for hours, and I've got a GTK2
widget ready that is getting fairly complete, rendering wise.

Need to do some small changes, and implement the 'list' and
'image' widget, and after that the current lvwidget_uicontainer
widget is capable of rendering the complete VisUI set.

After that I'll start working on propagating those new param settings
down the stack into the plugins. When that is up, and working I need
to setup a system that is capable of propagating up UI update
events from within the plugin, and that is when this goodie is getting
near done.

After that, we can start implementing config dialogs in plugins, using
VisUI, and also set up a standard VisUI config for libvisual itself.

We're far from done, a GTK1 widget needs to be produced as well :)

However, it's a start!

Duilio, After the GTK2 widget is done, could you look into a GTK1
widget ? (I think it's fairly easy to port the GTK2 version over).

When this is all set in stone, I'll contact the amarok develers
if they want to make a QT widget.

Cheers,
Dennis

Yep, there will be no mayor problems on this port.
I can do it when gtk2 widget is stable enough.


Bye,
Duilio.

Alright, good to hear, it's really getting better and better every hour!

It now updates VisParams on most userinterface components, after it's
completely done, I'll start cleaning it up, and work on a system that
is capable of notifying the UI of changes from within the plugin
as well, will be doing this in a callback setup fashion.

Does anyone has experience with GTK2 and threading, is there a way,
a function that locks all threads in a way GTK2 is happy, so I can
safely adjust values from within different threads ?

Cheers,
Dennis

Gtk2 doesn't handle threads by itself, it uses Glib for that. I'm not really
shure, but a way to control a chunk of threads is to use a pool of threads,
with GThreadPool. I cannot check this from where I'm right now, but I will
do at home.

Duilio.

Well, yeah I know, but the point is, if I'm not wrong, gtk is far from
thread safe, so I can't just poke around at the same thing, in different
threads, I've got to look into this as well :)
