SYNOPSIS

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

DESCRIPTION

The AG_ProgressBar widget binds to minimum, maximum and value integers and displays a progress bar representing the value.

INHERITANCE HIERARCHY

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

INITIALIZATION


AG_ProgressBar * AG_ProgressBarNew (AG_Widget *parent, enum ag_progress_bar_type type, Uint flags)

AG_ProgressBar * AG_ProgressBarNewInt (AG_Widget *parent, enum ag_progress_bar_type type, Uint flags, int *value, int *min, int *max)

AG_ProgressBar * AG_ProgressBarNewHoriz (AG_Widget *parent, Uint flags)

AG_ProgressBar * AG_ProgressBarNewVert (AG_Widget *parent, Uint flags)

void AG_ProgressBarSetWidth (AG_ProgressBar *pb, int width)

void AG_ProgressBarSetLength (AG_ProgressBar *pb, int length)

int AG_ProgressBarPercent (AG_ProgressBar *pb)


The AG_ProgressBarNew() function allocates, initializes, and attaches a new AG_ProgressBar widget. type defines the style:
enum ag_progress_bar_type {
	AG_PROGRESS_BAR_HORIZ,
	AG_PROGRESS_BAR_VERT
};

Acceptable flags include:
AG_PROGRESS_BAR_SHOW_PCTDisplay text showing the percentage.
AG_PROGRESS_BAR_EXCLAdvise that no external changes to the value, min and max bindings are expected. By default, the binding values are periodically checked and the progress bar is redrawn if a change is detected. Note that this setting only influences redraw -- external changes to the binding values are handled safely regardless.
AG_PROGRESS_BAR_HFILLExpand horizontally in parent (equivalent to invoking AG_ExpandHoriz(3)). If this flag is not used, AG_ProgressBarSetLength() should be called explicitely.
AG_PROGRESS_BAR_VFILLExpand vertically in parent (equivalent to invoking AG_ExpandVert(3)). If this flag is not used, AG_ProgressBarSetLength() should be called explicitely.
AG_PROGRESS_BAR_EXPANDShorthand for AG_PROGRESS_BAR_HFILL|AG_PROGRESS_BAR_VFILL.

The AG_ProgressBarNewInt() variant binds the value, min and max bindings on initialization.

The AG_ProgressBarNewHoriz() and AG_ProgressBarNewVert() variants specify the layout on initialization.

The AG_ProgressBarSetWidth() function sets the width of the bar in pixels.

AG_ProgressBarSetLength() requests a preferred length in pixels. Alternatively, AG_PROGRESS_BAR_HFILL or AG_PROGRESS_BAR_VFILL may be used.

The AG_ProgressBarPercent() returns the percentage for the currently bound value and range.

BINDINGS

The AG_ProgressBar widget provides the following bindings:
int *value Current value
int *min Minimum value
int *max Maximum value

EVENTS

The AG_ProgressBar widget does not generate any event.
