Detailed Description

Base class for Scrollbar window renderer objects.

Member Function Documentation

virtual float CEGUI::ScrollbarWindowRenderer::getAdjustDirectionFromPoint ( const Vector2f &  pt ) const

pure virtual

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

Parameters

pt	Point 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.

Implemented in CEGUI::FalagardScrollbar.

virtual float CEGUI::ScrollbarWindowRenderer::getValueFromThumb ( void  ) const

pure virtual

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.

Implemented in CEGUI::FalagardScrollbar.
