Member Function Documentation

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

pure virtual

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

Parameters

pt	Point object describing a pixel position in window space.

Returns

• -1 to indicate slider should be moved to a lower setting.
• 0 to indicate slider should not be moved.
• +1 to indicate slider should be moved to a higher setting.

Implemented in CEGUI::FalagardSlider.

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

pure virtual

return value that best represents current slider value given the current location of the thumb.

Returns

float value that, given the thumb widget position, best represents the current value for the slider.

Implemented in CEGUI::FalagardSlider.
