Re: What is "canvas"?

Felix,

... could you explain me briefly what a "canvas" is?


Let me try.  But please know that I'm myself a novice, just like you, so
take it with a grain
of salt.  I'd encourage veterans to step in and correct me if I get anything
wrong.

GtkPlotCanvas is a subclass of GtkFixed which means that it can arrange its
children in
more or less an arbitrary way depending on what the user wants.  GtkFixed
allows you
to drag-and-drop its children, resize them and more.  The mission of
GtkPlotCanvas is
to control the disposition of every element that visually makes up the
plot.  There are
at least two types of children that I can see that can be added to the
GtkPlotCanvas
object.  GtkPlot is one of them, and then there is "everything else" (texts,
lines, etc.)
which is all gathered under the same hood of GtkPlotCanvasChild.
