Member Function Documentation

Bool om::graphics::gui::objects::Knob::setSize

(

const Vector2f &

newSize

)

Set the size of this knob.

Since knobs are inherently circular, this method will fail, returning FALSE if the specified size is not square, i.e. both width and height are the same. Otherwise, if the sizes are equal, the method succeeds.

Float om::graphics::gui::objects::Knob::getRadius ( ) const

inline

Return the radius of this knob's circular area.

Bool om::graphics::gui::objects::Knob::setRadius

(

Float

newRadius

)

Set the radius of this knob's circular area.

The method returns whether or not the knob's radius was successfully changed. If the method succeeds, the knob automatically updates the radius of its border to match the knob's radius.

Float om::graphics::gui::objects::Knob::getValue ( ) const

inline

Return the current value for the knob.

void om::graphics::gui::objects::Knob::setValue

(

Float

newValue

)

Set the current value for the knob.

The new knob value is clamped to lie within the knob's valid range of values.

const AABB1f& om::graphics::gui::objects::Knob::getRange ( ) const

inline

Return an object that describes the minimum and maximum allowed values for the knob.

The range's minimum value is placed at the minimum coordinate of the knob's major axis, and the maximum value is placed at the maximum coordinate of the knob's major axis.

The minimum and maximum values do not have to be properly ordered - they can be reversed in order to reverse the effective direction of the knob.

void om::graphics::gui::objects::Knob::setRange

(

const AABB1f &

newRange

)

Set an object that describes the minimum and maximum allowed values for the knob.

The range's minimum value is placed at the minimum coordinate of the knob's major axis, and the maximum value is placed at the maximum coordinate of the knob's major axis.

The minimum and maximum values do not have to be properly ordered - they can be reversed in order to reverse the effective direction of the knob.

The knob's value is clamped so that is lies within the new range.

Size om::graphics::gui::objects::Knob::getStepCount ( ) const

inline

Return the total number of value steps there are for this knob.

This allows the user to quantize the knob's allowed values to a fixed number of evenly-spaced steps.

If this value is 0, the default, the knob's resolution is unquantized and can be used to represent any value in the valid range.

void om::graphics::gui::objects::Knob::setStepCount ( Size  newNumSteps )

inline

Set the total number of value steps there are for this knob.

This allows the user to quantize the knob's allowed values to a fixed number of evenly-spaced steps.

If this value is 0, the default, the knob's resolution is unquantized and can be used to represent any value in the valid range.

ValueCurve om::graphics::gui::objects::Knob::getValueCurve ( ) const

inline

Return an object representing the curve that is used to map from knob positions to values.

void om::graphics::gui::objects::Knob::setValueCurve ( ValueCurve  newCurve )

inline

Set an object representing the curve that is used to map from knob positions to values.

Float om::graphics::gui::objects::Knob::getSensitivity ( ) const

inline

Return the number of pixels the mouse must move to change the knob from the minimum to the maximum value.

void om::graphics::gui::objects::Knob::setSensitivity ( Float  newSensitivity )

inline

Set the number of pixels the mouse must move to change the knob from the minimum to the maximum value.

virtual Bool om::graphics::gui::objects::Knob::setBorder ( const Border &  newBorder )

virtual

Set an object that describes this knob's border.

The new border is set to have the same radius as the knob to preserve visual quality.

Reimplemented from om::graphics::gui::objects::GUIObject.

Vector2f om::graphics::gui::objects::Knob::getDirection ( ) const

inline

Return the normalized direction vector indicating the direction that the knob is turned.

Bool om::graphics::gui::objects::Knob::getIsEnabled ( ) const

inline

Return whether or not this knob is currently active.

An inactive knob may change its visual appearance to indicate that it is not able to be changed by the user.

void om::graphics::gui::objects::Knob::setIsEnabled ( Bool  newIsEnabled )

inline

Set whether or not this knob is currently active.

An inactive knob may change its visual appearance to indicate that it is not able to be changed by the user.

Bool om::graphics::gui::objects::Knob::getIsEditable ( ) const

inline

Return whether or not this knob is able to be edited by the user.

void om::graphics::gui::objects::Knob::setIsEditable ( Bool  newIsEditable )

inline

Return whether or not this knob is able to be edited by the user.

Bool om::graphics::gui::objects::Knob::getIsGrabbed ( ) const

inline

Return whether or not this knob is currently grabbed by the mouse.

const Color4f& om::graphics::gui::objects::Knob::getIndicatorColor ( ) const

inline

Return the color used when rendering a knob's rotation indicator.

void om::graphics::gui::objects::Knob::setIndicatorColor ( const Color4f &  newKnobIndicatorColor )

inline

Set the color used when rendering a knob's rotation indicator.

Float om::graphics::gui::objects::Knob::getIndicatorWidth ( ) const

inline

Return the width used when rendering a knob's rotation indicator.

This width is expressed here as a fraction of the knob's radius.

void om::graphics::gui::objects::Knob::setIndicatorWidth ( Float  newIndicatorWidth )

inline

Set the width used when rendering a knob's rotation indicator.

This width is expressed here as a fraction of the knob's radius.

virtual Bool om::graphics::gui::objects::Knob::containsLocalPoint ( const Vector2f &  localPoint ) const

virtual

Return whether or not this knob contains the specified local 2D point within its local bounds.

Reimplemented from om::graphics::gui::objects::GUIObject.

virtual Bool om::graphics::gui::objects::Knob::containsLocalPoint ( const Vector3f &  localPoint ) const

virtual

Return whether or not this knob contains the specified local 3D point within its local bounds.

Reimplemented from om::graphics::gui::objects::GUIObject.

virtual void om::graphics::gui::objects::Knob::update ( Float  dt )

virtual

Update the current internal state of this knob for the specified time interval in seconds.
