GTK most certainly has a blank widget, just like all the other
toolkits. Don't forget, it started as the GIMP Toolkit, and that
required a lot of custom widgets.
Look at https://developer.gnome.org/gtk3/3.12/GtkDrawingArea.html

I wanted to use Motif but support for it is vanishing it seems.
Athena, I hate the scrollbars. What I want to work at is an SDR
(Software Defined Radio) program so the more efficiently it can update
the spectrum area the better. It's almost like video, people use 2 -
30 frames per second, meanwhile getting data in over USB and doing an
FFT on it, plus demodulating in different threads. In real time.
I'm not seeing a widget in GTK that draws that efficiently. QT can do
it, or Java Swing, or even just plain old bare XLIB, except I wanted
some widgets. I was hoping to use a Motif DrawingArea. There isn't
room for a lot of bloat between the code and the screen. XDrawLine is
fast enough.
There's a qtcsdr https://github.com/ha7ilm/qtcsdr/archive/master.zip
which isn't bad as far as it goes, written with QT. It runs at 50%
CPU or so on a Raspberry Pi 3. I'd add a button to turn off screen
updates so it could run more in the background. Just playing with
ideas at this point.

I am a bit confused if you're talking of modern toolkits, or older
ones, or in general. If in general, than this is untrue — QtCreator
allows you to design GUI pretty much like Borland Delphi or Visual
Studio. For GTK alike thing is Glade — it's not so good as "design"
tab in QtCreator by virtue of being a stand alone utility, but
otherwise it works in alike fashion.

Hmm, thank you but http://motif.ics.com/forum is now read-only. As is
http://www.motifdeveloper.com/. I wanted to use C, not Lua.
Maybe I'll have to bite the bullet and learn QT. I have this theory
that part of the reason there's so little modern software for Unix in
general is because there aren't tools like Borland Delphi to write it
with. Yes, I've tried Lazarus and thought it was a hodgepodge of
patches with the documentation a worse hodgepodge. I have little
problem writing command line stuff but making any GUI work is like a
holy grail. Maybe Java Swing then it's portable. I was enjoying the
retro aspect though.

I like playing around with the old stuff, because to me it seems
simpler and more efficient than GTK3 or QT. When it works. I'm still
trying to wrap my brain around mapping, managing, realizing widgets in
the right order.
I started out, put a notebook into a window, then a rowcol onto a page
of it, then a drawing area in the top of that. When I try to draw to
it whatever I draw is clipped to about the top 10 pixels. Why? That
sort of stuff. Yes, I've got copies of vol6a, etc, the original
O'Reily books. If I spent a couple years reading I could probably
find the answer but I'd forget my question. Is there a forum of Motif
freaks?
The motif zone is still online : http://motif.ics.com/
and you may want to have a look at https://github.com/arcapos/luamotif

No, I won't call it "climate change", do you have a "reality problem"? -
