5/* this file defines the structure for "glists" and related structures and
6functions. "Glists" and "canvases" and "graphs" used to be different
7structures until being unified in version 0.35.
8
9A glist occupies its own window if the "gl_havewindow" flag is set. Its
10appearance on its "parent" or "owner" (if it has one) is as a graph if
11"gl_isgraph" is set, and otherwise as a text box.
12
13A glist is "root" if it has no owner, i.e., a document window. In this
14case "gl_havewindow" is always set.
15
16We maintain a list of root windows, so that we can traverse the whole
17collection of everything in a Pd process.
18
19If a glist has a window it may still not be "mapped." Miniaturized
20windows aren't mapped, for example, but a window is also not mapped
21immediately upon creation. In either case gl_havewindow is true but
22gl_mapped is false.
23
24Closing a non-root window makes it invisible; closing a root destroys it.
25
26A glist that's just a text object on its parent is always "toplevel." An
27embedded glist can switch back and forth to appear as a toplevel by double-
28clicking on it. Single-clicking a text box makes the toplevel become visible
29and raises the window it's in.
30
31If a glist shows up as a graph on its parent, the graph is blanked while the
32glist has its own window, even if miniaturized.

607/* this file defines the structure for "glists" and related structures and
608functions. "Glists" and "canvases" and "graphs" used to be different
609structures until being unified in version 0.35.
610
611A glist occupies its own window if the "gl_havewindow" flag is set. Its
612appearance on its "parent" or "owner" (if it has one) is as a graph if
613"gl_isgraph" is set, and otherwise as a text box.
614
615A glist is "root" if it has no owner, i.e., a document window. In this
616case "gl_havewindow" is always set.
617
618We maintain a list of root windows, so that we can traverse the whole
619collection of everything in a Pd process.
620
621If a glist has a window it may still not be "mapped." Miniaturized
622windows aren't mapped, for example, but a window is also not mapped
623immediately upon creation. In either case gl_havewindow is true but
624gl_mapped is false.
625
626Closing a non-root window makes it invisible; closing a root destroys it.
627
628A glist that's just a text object on its parent is always "toplevel." An
629embedded glist can switch back and forth to appear as a toplevel by double-
630clicking on it. Single-clicking a text box makes the toplevel become visible
631and raises the window it's in.
632
633If a glist shows up as a graph on its parent, the graph is blanked while the
634glist has its own window, even if miniaturized.
