Re: [Discuss-gnuradio] QT graphical sink: how set dimension?

[Vitt Benv]

Tnx Marcus, you are right, I'm speaking about "graphical" properties.
I was aware about "GUI Hint" and I tried this but only to put widgets
in rows x columns positions.... but now I know about the subsequent
parameter: I'll test those.

 Now I miss only Tabs as Notebook was used, but never mind, I'll try
another way!

About GRC I think it's a good "starting point" but then some extra
code does the job.

A useful feature in GRC could be to have some kind of protection on
added code between builds... if I recall right there was an IDE
(WxGlade... maybe...) who understood a simple tag as:

....
### PROTECTED CODE ###

... added code

###
....

so that in subsequent build that wasn't overwritten ( actually it
happened several times, sgrunt!).

Tnx again, ciao ^__^
