Detailed Description

A scrollbar attached to a scroll area.

A WScrollArea always has two scrollbars (even if they are not visible, for example when the policy is WScrollArea::ScrollBarAlwaysOff). Using the tie(WScrollBar *one, WScrollBar *two) functions, it is possible to tie two scrollbars together, so that they will scroll together.

setValue()

void Wt::WScrollBar::setValue

(

int

value

)

Sets the scrollbar value (in pixels).

This will move the scrollbar to the given value.

tie()

void Wt::WScrollBar::tie ( WScrollBar *  one, WScrollBar *  two  )

static

Ties two scrollbars together.

The effect of this call is that these scrollbars will keep their positions synchronised.

unTie()

void Wt::WScrollBar::unTie ( WScrollBar *  one, WScrollBar *  two  )

static

Unties two scrollbars, that were previously tied together.

Undo a tie(WScrollBar *one, WScrollBar *two);
