Class is FLTK widget which display MathGL graphics. It is defined in #include <mgl2/fltk.h>
.
void
set_draw (int
(*draw)(HMGL
gr, void *
p))void
set_draw (int
(*draw)(mglGraph *
gr))void
set_draw (mglDraw *
draw)Sets drawing function as global function or as one from a class mglDraw
. There is support of a list of plots (frames). So as one can prepare a set of frames at first and redraw it fast later (but it requires more memory). Function should return positive number of frames for the list or zero if it will plot directly. Parameter par contains pointer to data for the plotting function draw.
void
update ()Update (redraw) plot.
void
set_angle (mreal
t, mreal
p)Set angles for additional plot rotation
void
set_flag (int
f)Set bitwise flags for general state (1-Alpha, 2-Light)
void
set_state (bool
r, bool
z)Set flags for handling mouse:
z=true
allow zooming,
r=true
allow rotation/shifting/perspective and so on.
void
set_zoom (mreal
X1, mreal
Y1, mreal
X2, mreal
Y2)Set zoom in/out region
void
get_zoom (mreal *
X1, mreal *
Y1, mreal *
X2, mreal *
Y2)Get zoom in/out region
void
set_popup (const Fl_Menu_Item *
pmenu, Fl_Widget *
w, void *
v)Set popup menu pointer
void
set_graph (mglCanvas *
gr)void
set_graph (mglGraph *
gr)Set new grapher instead of built-in one. Note that Fl_MathGL will automatically delete this object at destruction or at new set_graph()
call.
HMGL
get_graph ()Get pointer to grapher.
Fl_Valuator *
tet_valPointer to external tet-angle validator.
Fl_Valuator *
phi_valPointer to external phi-angle validator.
