Hi all,

im new to ruby and ruby-gnome2 and my questions should be very basic,  
anyway, here are some questions about ruby-gnome2:

- When i use the GTKMozEmbed widget the scrollbar uses the mozilla theme  
instead of the GNOME theme, is it possible to make the GTKMozEmbed  
scrollbar to look like all GNOME scrollbars?

- Is there any way to use a spellchecker in the TextView or SourceView  
widgets? Looking to the API it seems not to be any GTKSpell widget, so i  
don’t know what would be the way to implement the spellchecker feature.

- I would like to restore the main window position and size as the last  
time the user closed the application, there’s no problem with position  
and size but i don’t know how to check if the window was maximized when  
the user closed it.

- I’m using a trayicon in my application, adding to it an EventBox with  
and image, it works nice, but the image is not resized to fit the tray.  
I’m using a .svg file format for the image.

I think this is all at the moment, i hope somebody can point me the in  
right way.

Don’t know…

GtkSpell is obsolate since several years.

Several years ago i used aspell with C and it was very easy. A short  
look at [raspell download | SourceForge.net](http://sourceforge.net/projects/raspell/) the ruby aspell  
bindings shows that it is also very easy.

That is someting your windowmanager shall do via the session management.  
But i think ruby-gtk cant handle this for now.

i do this in my code:

```
  @tray = Gtk::TrayIcon.new("test")
  @traybox = Gtk::EventBox.new
  @trayimage = Gtk::Image.new
  @tray.add @traybox
  @traybox.add @trayimage
  @tooltip = Gtk::Tooltips.new
  @traysize = 0

  @tray.signal_connect("configure_event") do |widget, event|
    @traysize = event.width > event.height ? event.width :

```

event.height  
@traysize = @traysize / 2  
@traysize = 4 if @traysize \< 4  
end

```
  @tray.signal_connect("map_event") do
    pixbuf =

```

Gdk::Pixbuf.new(“#{@datadir}/pixmaps/radaubruder/radaubruder.svg”,  
@traysize, @traysize)  
@trayimage.pixbuf = pixbuf  
end

```
  @tray.show_all

```

yeah, this is very strange as in the rubizilla sample movie the  
scrollbars look nice, but when i try the sample myself the scrollbars  
are like the default mozilla theme instead of GNOME scrollbars.

thanks, i will take a look to it. Anyway, what i would like to do is  
underline spell errors when the user writes, im not sure if this is  
possible with the gtktextview or i should use some kind of pango object.

That’s quite easy:

-------v GdkWindow  
window.window.state & Gtk:🪟:STATE\_MAXIMIZED  
--------------^ GdkWindowState

(maybe wrong - i just don’t have ruby-gnome2 installed here, but that’s  
how it should work)

The Gnome policy for these features is like that:

The window manager is responsible for window management, if an  
application wants to restore the window size, position and state, it  
needs to do this on its own (just because only the application developer  
knows which kinds of windows are of the same “type” - where “type” can  
be “main window”, “properties box”, “file save dialog”).

Session management is something that should be implemented by  
applications and a session manager.
