Member Function Documentation

float CEGUI::FalagardScrollbar::getAdjustDirectionFromPoint ( const Vector2f pt) const
protectedvirtual

Given window location pt, return a value indicating what change should be made to the scroll bar.

Parameters
ptPoint object describing a pixel position in window space.
Returns
  • -1 to indicate scroll bar position should be moved to a lower value.
  • 0 to indicate scroll bar position should not be changed.
  • +1 to indicate scroll bar position should be moved to a higher value.

Implements CEGUI::ScrollbarWindowRenderer.

float CEGUI::FalagardScrollbar::getValueFromThumb ( void  ) const
protectedvirtual

return value that best represents current scroll bar position given the current location of the thumb.

Returns
float value that, given the thumb widget position, best represents the current position for the scroll bar.

Implements CEGUI::ScrollbarWindowRenderer.

void CEGUI::FalagardScrollbar::render ( )
virtual

Populate render cache.

This method must be implemented by all window renderers and should perform the rendering operations needed for this widget. Normally using the Falagard API...
