AG_BoxSetDepth(3)

SYNOPSIS

#include <agar/core.h>
#include <agar/gui.h>

DESCRIPTION

ScreenshotAG_Box is a general-purpose container widget which aligns and packs its widgets either horizontally or vertically based on their size requisitions and adds spacing and padding. Overflowing widgets are clipped.

Widgets with AG_WIDGET_HFILL expand horizontally to fill remaining space. Widgets with AG_WIDGET_VFILL expand vertically to fill remaining space.

Horizontal boxes allow only up to 1 widget with AG_WIDGET_HFILL (and any number with AG_WIDGET_VFILL).

Vertical boxes allow only up to 1 widget with AG_WIDGET_VFILL (and any number with AG_WIDGET_HFILL).

INHERITANCE HIERARCHY

AG_Object(3)-> AG_Widget(3)-> AG_Box.

INITIALIZATION


AG_Box * AG_BoxNew (AG_Widget *parent, enum ag_box_type type, Uint flags)

AG_Box * AG_BoxNewHoriz (AG_Widget *parent, Uint flags)

AG_Box * AG_BoxNewVert (AG_Widget *parent, Uint flags)

void AG_BoxSetLabel (AG_Box *box, const char *format, ...)

void AG_BoxSetLabelS (AG_Box *box, const char *text)

void AG_BoxSizeHint (AG_Box *box, int width, int height)

void AG_BoxSetHomogenous (AG_Box *box, int homogenous)

void AG_BoxSetDepth (AG_Box *box, int depth)

void AG_BoxSetHorizAlign (AG_Box *box, enum ag_box_align align)

void AG_BoxSetVertAlign (AG_Box *box, enum ag_box_align align)


AG_BoxNew() allocates, initializes, and attaches a new AG_Box container. type can be AG_BOX_HORIZ for horizontal packing AG_BOX_VERT for vertical packing. Acceptable flags include:
AG_BOX_HOMOGENOUSDivide space into equal parts.
AG_BOX_SHADINGShow 3D-style shading even if no "background-color".
AG_BOX_HFILLExpand horizontally in parent container.
AG_BOX_VFILLExpand vertically in parent container.
AG_BOX_EXPANDShorthand for AG_BOX_HFILL AG_BOX_VFILL|.
AG_BOX_NO_SPACINGSet "padding" and "spacing" style attributes to "0".

The AG_BoxNewHoriz() and AG_BoxNewVert() variants are equivalent to setting AG_BOX_HORIZ and AG_BOX_VERT.

AG_BoxSetStyle() selects an alternate background and border style:
AG_BOX_STYLE_NONE No background.
AG_BOX_STYLE_BOX Raised box & border.
AG_BOX_STYLE_WELL 3D well & border (the default).
AG_BOX_STYLE_PLAIN Filled rectangle.

Visible background styles use the style attributes "background-color", "low-color" and "high-color".

AG_BoxSetLabel() arranges for a text label to be displayed over the container. If an argument of NULL is passed, the label is removed.

AG_BoxSizeHint() sets a specific size requisition in pixels (-1 = auto). The default is determined by the size requisition of attached widgets.

AG_BoxSetHomogenous() sets or clears the AG_BOX_HOMOGENOUS flag, which controls whether available space is divided evenly between widgets.

AG_BoxSetDepth() sets the depth of the shading for AG_BOX_SHADING.

AG_BoxSetHorizAlign() and AG_BoxSetVertAlign() specify the horizontal or vertical alignment of widgets. Horizontal alignment can be AG_BOX_LEFT (default), AG_BOX_CENTER or AG_BOX_RIGHT. Vertical alignment can be AG_BOX_TOP (default), AG_BOX_CENTER or AG_BOX_BOTTOM.

EVENTS

The AG_Box widget does not generate any event.

STRUCTURE DATA

For the AG_Box object:
enum ag_box_style style Background style (see AG_BoxSetStyle()).

EXAMPLES

The following code fragment packs two columns of buttons:
AG_Window *win;
AG_Box *boxHoriz, *boxCol[2];
int i;

win = AG_WindowNew(0);
boxHoriz = AG_BoxNewVert(win, 0);
boxCol[0] = AG_BoxNewHoriz(boxHoriz, 0);
boxCol[1] = AG_BoxNewHoriz(boxHoriz, 0);

for (i = 0; i < 5; i++)
	AG_ButtonNew(boxCol[0], 0, "In column 1");
for (i = 0; i < 5; i++)
	AG_ButtonNew(boxCol[1], 0, "In column 2");

AG_WindowShow(win);

The AG_Box widget first appeared in Agar 1.0. In Agar 1.6.0, the AG_BoxSetPadding() and AG_BoxSetSpacing() functions were deprecated in favor of the generic "padding" and "spacing" style attributes.
