Hello everyone,
i use gtk::windows with various content(child) widgets like
#gstreamer widget
class SimpleVideoWidget < Gtk::DrawingArea
…
end
#image widget
class SimpleImageWidget < Gtk::Image
…
end
#html widget
class WebkitWidget < Gtk::WebKit::WebView
…
end
now i want to set them transparent.
i found some cairo samples but im not sure if the are right for me
http://www.pri.univie.ac.at/~mangler/alphademo/alphademo.rb
my composite manager is enabled
Gdk::Screen.default.composited? is true
and here i get the rgba colormap
Gdk::Screen.default.rgba_colormap
do i have to use gtk:window#.input_shape_combine_mask(,0,0)?
does anyone have any hints ?
thanks ahead
Philipp
does anyone have any hints ?
ruby-gnome2/trunk/gtk/sample/misc/composited-windows.rb might be a
good startting point.

Hello Guillaume,
thanks for the information …
got it to work. if composite is enabled u can use
gtk::window#set_opacity()
alpha must be between 0 an 1
e.g
@fraticles["#{fraticle[‘id’]}"].signal_connect_after(‘map-event’) do
|widget, event|
widget.window.set_opacity(0.8)
end
i think its also important where u call the functions because sometimes
alpha was set for a window but it was not transparent … got best
results with the map-event
regards
Philipp

I don’t understand fully what you’re saying: do you imply that the
mentioned example should be fixed? Can you provide a patch if that’s
the case? Or do you mean there is another way to do the same thing?
Can you program a short demo program if that’s the case?

Hello Guillaume,
im not sure if this is a bug, or my fault
i loop through a xml and create 1-5 windows … after 10-20 secs the
windows will be destroyed and i create new windows …
here my code to create the window
xml_fraticles.find(‘fraticle’).each{|fraticle|
@fraticles["#{fraticle[‘id’]}"] = Gtk::Window.new
@fraticles["#{fraticle[‘id’]}"].screen =
Gdk::DisplayManager.get.default_display.get_screen
fraticle[‘x11screen’].to_i
@fraticles["#{fraticle[‘id’]}"].move(fraticle[‘left’].to_i,fraticle[‘top’].to_i)
@fraticles["#{fraticle[‘id’]}"].resize(fraticle[‘width’].to_i,fraticle[‘height’].to_i)
@fraticles["#{fraticle[‘id’]}"].decorated = false
fraticles["#{fraticle[‘id’]}"].add
eval(fraticle[‘playermodule’]).new(self, fraticle)
@fraticles["#{fraticle[‘id’]}"].set_opacity(0.8)
<<<<<<<<<<<<<<<<<<<<<< if i call it here only a few windows are
transparent
@fraticles["#{fraticle[‘id’]}"].signal_connect_after(‘map-event’) do
|widget, event|
widget.window.set_opacity(0.8)<<<<<<<<<< if i call i here
its working for all windows
end
}
hi:
I am trying use the set_sort_func from the sortable interface for
liststore or for a column in a treeview.
By now i can order columns like this:
column.set_sort_column_id(3)
This works but i can not have my own set_sort_func
or,
@list_store_productos.set_sort_column_id(3)
@list_store_productos.set_sort_func(3){|iter1,iter2|
}
But this fail to me.
Any ideas?

Could you show us your example script that is executable?
Thanks,
