OK, I *KNOW* I''ve got a case of tunnel vision here. I''ve
written apps
that use wxRuby without a problem. Regardless, I don''t see what
I''m
doing wrong here. The code in my main routine looks like this:
class MyApp < Wx::App
def on_init
f = Video.new(nil)
f.show
end
end
app = MyApp.new
app.main_loop
There is only one simple window in the app - created via wxFormBuilder.
The window (a frame) displays cleanly. Problem: when I close this window
(either by clicking the "X" or by issuing a call to self.close()
through
an event, the app doesn''t exit. It simply goes to sleep. The only way I
see to close it is to go to a terminal and issue a "kill" command.
I''m running under Ubuntu 9.10.
Would someone be so kind as to point out what I''m missing - which
I''m
sure is going to be obvious to everyone but me.

I''ve had similar behavior and it was due to the app still holding
resources. For me, I created a dock_icon that wants to be destroyed
prior to exiting.
So, in short, check if your code still holds any resources that need
manual destruction and call them in an on_close method ... for instance:
class YourFrame < Wx::Frame
def initialize
(...)
evt_close :on_close
(...)
@dock_icon = Wx::TaskBarIcon.new
@dock_icon.set_icon((Wx::Icon.new("icon.png",
Wx::BITMAP_TYPE_PNG)),"Your App")
end
(...)
def on_close
@dock_icon.destroy if @dock_icon
destroy
end
end

Yes, this normally. As far as know, the only things that need manual destruction are: TaskBarIcon Dialog, when created with no window as parent What these have in common is that they are GUI elements which should persist even if there is no main window (some kind of Wx::Frame) for the application. Everything else should be cleaned up automatically as an application runs and windows open and close. a
