The AG_Toolbar widget is a specialized container for a set of buttons which allows single or multiple selections. The buttons may be arranged in multiple rows.

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

The AG_ToolbarNew() function allocates, initializes, and attaches a new AG_Toolbar widget. Acceptable flags include:

AG_TOOLBAR_HOMOGENOUS	Scale the buttons so that they cover the whole toolbar area, instead of using their preferred sizes.
AG_TOOLBAR_STICKY	Buttons should preserve their state, and only one button can be selected at any given time.
AG_TOOLBAR_MULTI_STICKY	Button should preserve their state but multiple buttons can be selected.
AG_TOOLBAR_HFILL	Expand horizontally in parent container.
AG_TOOLBAR_VFILL	Expand veritcally in parent container.
AG_TOOLBAR_EXPAND	Shorthand for AG_TOOLBAR_HFILL AG_TOOLBAR_VFILL|.

AG_ToolbarRow() specifies the row number for all subsequent operations.

The AG_ToolbarButton() function creates a new button displaying the given text and attaches it to the current row. If the enable_default argument is 1, the button is enabled by default. The arguments fn and fnArg specify the event handler function (see AG_Event(3) for details). The callback function will be invoked whenever the user clicks on the button.

The AG_ToolbarButtonIcon() variant creates a button displaying a given surface instead of a label, usually an icon.

AG_ToolbarSeparator() creates a separator of appropriate orientation in the current row.

The functions AG_ToolbarSelect() and AG_ToolbarDeselect() are used to enable or disable a given button. AG_ToolbarSelectOnly() enables the given button, disabling any other button that is currently active. AG_ToolbarSelectAll() enables all attached buttons and AG_ToolbarDeselectAll() disables all attached buttons.

The AG_Toolbar widget does not generate any event.

For the AG_Toolbar object:

AG_Box *rows[]	Containers for the rows (read-only). Widgets can be attached manually to those containers with AG_ObjectAttach(3) if AG_ToolbarButton() is not suitable.
int nRows	Number of rows (read-only).
int nButtons	Total button count (read-only).
int curRow	Current row, as selected by AG_ToolbarRow() (read-only).
