Detailed Description

This Helper class defines generically the TabGroup behavior when there is more tabs than available horizontal width, i.e it can generates a popup menu or shrink It opens the door to new Pagers creation as left- rights arrows scrolling pagers and others ... To create a new pager, inherits from TabGroupPager and redefines the pure virtual methods of this template.

virtual bool fltk::TabGroupPager::draw_tabs	(	TabGroup *	g,
		int	selected,
		int *	tab_pos,
		int *	tab_width
	)			[inline, virtual]

draw the tabs for this custom pager, return false means no custom draw is made

void fltk::TabGroupPager::noclip

(

bool

v

)

[inline]

determines if we forbid partial tabs drawing with clipping

int fltk::TabGroupPager::shift

(

)

const [inline]

shifting to nth+1 tab to draw, permit to 'keep' a position while changing tabs and tab is in the interval

virtual int fltk::TabGroupPager::update_positions	(	TabGroup *	g,
		int	numchildren,
		int &	selected,
		int &	cumulated_width,
		int &	available_width,
		int *	tab_pos,
		int *	tab_width
	)			[inline, virtual]

this method must update the tab positions and width array, returns the selected tab

virtual int fltk::TabGroupPager::which	(	TabGroup *	g,
		int	m_x,
		int	m_y
	)			[pure virtual]

determine and return the index of the child group at the corresponding pos
