NAME

AG_ProgressBar —

agar progress bar widget

SYNOPSIS

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

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

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

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_PCT: Display text showing the percentage.
AG_PROGRESS_BAR_EXCL: Advise 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_HFILL: Expand horizontally in parent (equivalent to invoking AG_ExpandHoriz(3)). If this flag is not used, AG_ProgressBarSetLength() should be called explicitely.
AG_PROGRESS_BAR_VFILL: Expand vertically in parent (equivalent to invoking AG_ExpandVert(3)). If this flag is not used, AG_ProgressBarSetLength() should be called explicitely.
AG_PROGRESS_BAR_EXPAND: Shorthand 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.

The AG_ProgressBar widget provides the following bindings:

The AG_ProgressBar widget does not generate any event.

The AG_ProgressBar widget first appeared in Agar 1.3.
