5.3 QMathGL class
Class is Qt widget which display MathGL graphics. It is defined in #include <mgl2/qt.h>.
- Method on QMathGL:
void setDraw (mglDraw *dr)
Sets drawing functions from a class inherited from mglDraw.
- Method on QMathGL:
void setDraw (int (*draw)(mglBase *gr, void *p), void *par=NULL)
- Method on QMathGL:
void setDraw (int (*draw)(mglGraph *gr))
Sets the drawing function draw. 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.
- Method on QMathGL:
void setGraph (HMGL gr)
- Method on QMathGL:
void setGraph (mglGraph *gr)
Set pointer to external grapher (instead of built-in one). Note that QMathGL will automatically delete this object at destruction or at new setGraph() call.
- Method on QMathGL:
HMGL getGraph ()
Get pointer to grapher.
- Method on QMathGL:
void setPopup (QMenu *p)
Set popup menu pointer.

void setSize (int w, int h)
Set widget/picture sizes

double getRatio ()
Return aspect ratio of the picture.
- Method on QMathGL:
int getPer ()
Get perspective value in percents.
- Method on QMathGL:
int getPhi ()
Get Phi-angle value in degrees.
- Method on QMathGL:
int getTet ()
Get Theta-angle value in degrees.
- Method on QMathGL:
