SYNOPSIS

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

DESCRIPTION

The AG_Notebook widget maintains a set of AG_Box(3) containers, only one of which is visible at any given time. The user can select the visible container by clicking on a tab, or it can be selected programmatically.

INHERITANCE HIERARCHY

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

INITIALIZATION


AG_Notebook * AG_NotebookNew (AG_Widget *parent, Uint flags)

void AG_NotebookSetPadding (AG_Notebook *nb, int padding)

void AG_NotebookSetSpacing (AG_Notebook *nb, int spacing)

void AG_NotebookSetTabAlignment (AG_Notebook *nb, enum ag_notebook_tab_alignment alignment)

void AG_NotebookSetTabVisibility (AG_Notebook *nb, int flag)


The AG_NotebookNew() function allocates, initializes, and attaches a new AG_Notebook widget. Acceptable flags include:
AG_NOTEBOOK_HIDE_TABSDon't display the tab selector controls.
AG_NOTEBOOK_HFILLExpand horizontally in parent container.
AG_NOTEBOOK_VFILLExpand vertically in parent container.
AG_NOTEBOOK_EXPANDShorthand for AG_NOTEBOOK_HFILL AG_NOTEBOOK_VFILL|.

AG_NotebookSetPadding() and AG_NotebookSetSpacing() sets the default AG_Box(3) padding and spacing to use for new tabs.

By default, tabs are drawn at the top of the widget. AG_NotebookSetTabAlignment() changes the location of the tabs, where the argument is one of:
enum ag_notebook_tab_alignment {
	AG_NOTEBOOK_TABS_TOP,
	AG_NOTEBOOK_TABS_BOTTOM,
	AG_NOTEBOOK_TABS_LEFT,
	AG_NOTEBOOK_TABS_RIGHT
};

AG_NotebookSetTabVisibility() toggles the visibility of the tab header.

TAB MANAGEMENT


AG_NotebookTab * AG_NotebookAdd (AG_Notebook *nb, const char *name, enum ag_box_type type)

void AG_NotebookDel (AG_Notebook *nb, AG_NotebookTab *tab)

AG_NotebookTab * AG_NotebookGetByID (AG_Notebook *nb, int tabID)

AG_NotebookTab * AG_NotebookGetByName (AG_Notebook *nb, const char *text)

void AG_NotebookSelect (AG_Notebook *nb, AG_NotebookTab *tab)

void AG_NotebookSelectByID (AG_Notebook *nb, int id)


AG_NotebookAdd() creates a new tabbed container. name is an arbitrary text label to be displayed on the tab header. The type argument sets the type of AG_Box(3), that is either for AG_BOX_HORIZ horizontal packing, or AG_BOX_VERT for vertical packing (see AG_Box(3) for details). AG_NotebookAdd() returns a pointer to the newly created AG_NotebookTab container widget (a subclass of AG_Box(3)).

AG_NotebookDel() removes the given tabbed container, detaching and freeing all associated child widgets.

AG_NotebookGetByID() returns the tab with given numerical ID (or NULL).

AG_NotebookGetByName() looks up a tab based on the contents of its text label and returns a pointer to the tab (or NULL).

The AG_NotebookSelect() function selects the active tabbed container.

AG_NotebookSelectByID() selects the container by numerical ID.

EVENTS

The AG_Notebook widget does not generate any event.

STRUCTURE DATA

For the AG_Notebook object:
TAILQ tabs The list of tabs as AG_NotebookTab objects.
Uint nTabs Total number of tabs.
AG_NotebookTab *selTab Pointer to the currently selected tab.
int selTabID Numerical ID of currently selected tab.

For the AG_NotebookTab object:
AG_Label *lbl Pointer to the AG_Label(3) of the tab (or NULL).
int id The numerical ID associated with the tab.

EXAMPLES

The following code fragment creates a notebook with two tabs:
AG_Notebook *nb;
AG_Notebook *ntab;

nb = AG_NotebookNew(parent, AG_NOTEBOOK_EXPAND);
{
	ntab = AG_NotebookAdd(nb, "Tab #1", AG_BOX_VERT);
	AG_LabelNew(ntab, 0, "This is Tab #1");

	ntab = AG_NotebookAdd(nb, "Tab #2", AG_BOX_VERT);
	AG_LabelNew(ntab, 0, "This is Tab #2");
}
