Re: GTK3 + gnuplot
Hi Arkkimede, With gnuplot you can output to a file and then open the file with GTK+. https://gitlab.com/cecashon/OrderedSetVelociRaptor/blob/master/Misc/Pipes/gnuplot5.c At one time gnuplot could directly write to GTK but that was a possible security problem so it no longer works to do this. Gnuplot has 3d graphing plots and I think that it does this with cairo. You can graph in 3d with cairo but you need to do a few extra calculations before drawing with cairo. The Graphene library has a number of functions that are very helpful for drawing in 3d. It is part of GTK4 but you can use it in GTK3. https://developer.gnome.org/graphene/stable/ch01.html Another option is to write your own helper functions for drawing with cairo in 3d. https://gitlab.com/cecashon/OrderedSetVelociRaptor/blob/master/Misc/cairo_drawings/perspective3.c https://gitlab.com/cecashon/OrderedSetVelociRaptor/blob/master/Misc/cairo_drawings/perspective4.c https://gitlab.com/cecashon/OrderedSetVelociRaptor/blob/master/Misc/cairo_drawings/shadow1.c https://gitlab.com/cecashon/OrderedSetVelociRaptor/blob/master/Misc/cairo_drawings/shadow2.c https://gitlab.com/cecashon/OrderedSetVelociRaptor/blob/master/Misc/cairo_drawings/spring2.c So options abound for putting together a 3d plotting widget in GTK.

Get gnuplot to produce a PNG file, load the PNG into a GdkPixbuf, then stick the GdkPixbuf onto a cairo surface. You could take a look at https://sourceforge.net/p/gretl/git/ci/master/tree/gui/gpt_control.c in particular the function render_pngfile(). -- Allin Cottrell Department of Economics Wake Forest University, NC ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
Re: GTK3 + gnuplot
That would be awkward in gnuplot--you'd have to create the plot and then load it as a pixmap or some such. But there's a utility call plplot that's designed to be embedded in other applications and it might work better. https://tschoonj.github.io/blog/2015/07/05/embedding-plplot-in-gtk-drawingareas/ and https://sourceforge.net/p/plplot/mailman/message/26169132/ might help.

State actions and Glade
I am trying to write an application using Glade where the tool bar contains
a set of radio tool buttons. Those radio tool buttons should not perform an
action when activated but rather just change the associated action's state.
For that I've set the 'Action Name' property for the tool buttons in Glade
as 'win.radio-state(0)' and 'win.radio-state(1)'.
Since the only thing that I am after is the action's state, I don't even
need a 'chage_state' handler in the action definition. Therefore, the
GActionEntry for the radio buttons is defined as:
{"radio-state", NULL, "i", "0", NULL}
However, no matter what I do, the tool radio buttons are never 'sensitive'
and I can never click on them.
How should I be using state actions with Glade? It seems that I am doing
things as described by https://wiki.gnome.org/HowDoI/GAction but it still
does not work.
Thank you for your help.
