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_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.

AG_PROGRESS_BAR_HFILL
    Expand horizontally in parent container.

AG_PROGRESS_BAR_VFILL
    Expand vertically in parent container.

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.
