M_MATVIEW(3)		    Library Functions Manual		  M_MATVIEW(3)

NAME
       M_Matview -- Agar-Math matrix viewer widget

SYNOPSIS
       #include	<agar/core.h>
       #include	<agar/gui.h>
       #include	<agar/math/m.h>

DESCRIPTION
       The M_Matview widget displays the contents of a M_Matrix(3), either nu-
       merically or graphically.

INHERITANCE HIERARCHY
       AG_Object(3) -> AG_Widget(3) -> M_Matview.

INITIALIZATION
       M_Matview * M_MatviewNew(AG_Widget *parent, M_Matrix *M,	Uint flags)

       void M_MatviewSizeHint(M_Matview	*mv, const char	*text, Uint m, Uint n)

       void M_MatviewSetMatrix(M_Matview *mv, M_Matrix *M)

       void M_MatviewSetDisplayMode(M_Matview *mv, enum	m_matview_mode mode)

       void M_MatviewSetNumericalFmt(M_Matview *mv, const char *fmt)

       The  M_MatviewNew() function allocates, initializes, and	attaches a new
       M_Matview widget	displaying the matrix M	 (if  not  NULL).   Acceptable
       flags include:

       M_MATVIEW_HFILL	  Expand horizontally in parent	container.

       M_MATVIEW_VFILL	  Expand vertically in parent container.

       M_MATVIEW_EXPAND	  Shorthand for	M_MATVIEW_HFILL	| M_MATVIEW_VFILL.

       M_MatviewSizeHint() sets	an initial preferred widget size such that the
       widget can display m by n cells containing the specified	text string.

       M_MatviewSetMatrix()  changes  the matrix currently associated with the
       widget.

       M_MatviewSetDisplayMode() selects the display mode, where mode can be:

       enum m_matview_mode {
	       M_MATVIEW_GREYSCALE,    /* Graphical rendering (greyscale) */
	       M_MATVIEW_NUMERICAL     /* Numerical display */
       };

       M_MatviewSetNumericalFmt() configures the numerical format  (i.e.,  the
       printf(3) format	string)	that will be used to display element values.

EVENTS
       The M_Matview widget does not generate any event.

STRUCTURE DATA
       For the M_Matview object:

       int hSpacing   Horizontal spacing between entries
       int vSpacing   Vertical spacing between entries
       int xOffs      X	display	offset (bound to scrollbar)
       int yOffs      Y	display	offset (bound to scrollbar)
       int scale      Scaling factor in	graphical mode

SEE ALSO
       AG_Intro(3), AG_Widget(3), M_Matrix(3)

HISTORY
       The M_Matview widget first appeared in Agar 1.3.4.

Agar 1.7		       December	21, 2022		  M_MATVIEW(3)
