Hi,
Before I spend any time to rewrite the gtkmeter.c/h widget for JAMin to
gtk3/cairo does anyone have one already finished?
Needs to be in C.

Therè's this one:
https://github.com/sat-metalab/scenic/blob/master/src/vumeter/vumeter.cpp
https://github.com/sat-metalab/scenic/blob/master/src/include/vumeter.h
It has only a few c++isms and could easily be purely in C.
Best,
Tristan

Thanks. It does look useful. Seems to be written for gtk2 though. Have you
compiled it with gtk3?

its not exactly atypical to find that what you want doesn't exist and you
have to blend bits and piece.

at the very least, it would need a draw() method rather than an
expose()
method.
plus, if i read it correctly it also redraws its entire self (subject

Can you provide a small main.c or something?
All I see in there are static init functions never called.
Yeah it's just the class, no wrapping.
It can be called like this:
GtkWidget *gtkmeter;
GtkAdjustment *adjustment = (GtkAdjustment*) gtk_adjustment_new(0.0,
-40,
6, 0.0, 0.0, 0.0);
meter = gtk_meter_net(adjustment, GTK_METER_UP, 0. -40, 6);

Hi,
FYI, I have updated the class with some basic structure for adding
different cairo drawing functions. If anyone wants to take a look at the
code and make improvements feel free. I haven't added the fastmeter logic
yet.
http://boosthardware.com/code/jamin/
You can call it like this:
#include <gtkmeter.h>
GtkWidget *gtkmeter;
GtkAdjustment *adjustment = (GtkAdjustment*) gtk_adjustment_new(0.0, -40,
6, 0.0, 0.0, 0.0);
meter = gtk_meter_net(adjustment, GTK_METER_UP, GTK_METERSCALE_TOP. -40, 6);
gtk_meter_set_adjustment(GTK_METER (meter), adjustment);
- I have added it to the gtk3 port of JAMin which you can download from
http://jamin.sf.net to see it in action. It's all in the git repo.
Check these files for more advanced examples:
callbacks.c
interface.c
gtkmeter.c
intrim.c
compressor-ui.c
I'll put together a README when I have some more time.

Hi
There is still the fastmeter in our actuel Source, you can found it in guitarix/libgxw
It's plain c but gtk2.
The c++ wrapper is in libgxwmm.
Sorry for been short and wrong spelling, i hate to wrote on my Mobil.

Back in the days I had time to help Herman Meyer on his guitarix project,
I imported ardour's fast meters into C. Guitarix was using the C version
of gtk. You can look into the old guitarix code in sourceforge (that was a
long while back, maybe 3-4 years).

Thanks. It does look useful. Seems to be written for gtk2 though. Have
you
compiled it with gtk3?
at the very least, it would need a draw() method rather than an
expose()
method.
plus, if i read it correctly it also redraws its entire self (subject
to
cairo clipping) on every expose.
contrast with the the fastmeter in ardour3's libs/gtkmm2ext which draws
only the changed pixels per expose.

Yeah looks like this is going to have to be done the hard way. The
guitarix code is definitely in cCbut it also use gtk_drawable which means
I have to convert it to cairo for gtk3.
So, I guess I will integrate the cairo code from fastmeter with the
"almost" c code from Tristans while using the guitarix port as a reference
and trying to maintain the structure of hte original gtkmeter from JAMin
:-)
Oh yeah!

well it depends on what you want. tristan's has level markings etc. as
part
of the meter widget, and is very close to a pure C widget. mine has a very
efficient and C-ish drawing method that was created with gtk3 in mind.
its not exactly atypical to find that what you want doesn't exist and you
have to blend bits and piece.
