Detailed Description

Slider widget, which has a sliding interface to allow for arbitrary value selections from 0.0 to 1.0.

Constructor & Destructor Documentation

◆ Slider() [1/3]

hdi::core::Slider::Slider ( )

Constructs an empty Slider object.

Author: GW

Date: 09/2013

Note: To test if a Slider object is empty, call isEmpty() on it; Empty Slider objects do not relate to any actual UI widget; they are designed to be "receivers" of some other Slider object via the overloaded assignment operator. Empty Slider objects are useless until such time (though it is safe to call any of their methods).

◆ Slider() [2/3]

hdi::core::Slider::Slider ( const Slider & slider_ )

Constructs a new Slider object from an existing Slider object (copy constructor)

Author: GW

Date: 09/2013

Parameters

slider_ Existing Slider object

◆ Slider() [3/3]

hdi::core::Slider::Slider	(	const Point &	loc_,
		const double	value_,
		const double	width_
	)

Constructs a slider.

Author: GW

Date: 09/2013

Parameters

loc_	Position of the slider, in 1x resolution coordinates
value_	Initial value of the Slider in the range [0.0, 1.0]
width_	Width of the slider, at 1x resolution

◆ ~Slider()

virtual hdi::core::Slider::~Slider ( )

virtual

Slider destructor.

Author: GW

Date: 09/2013

Member Function Documentation

◆ clone()

virtual Slider * hdi::core::Slider::clone ( ) const

virtual

Convenience method to clone a Slider object on the heap.

Author: GW

Date: 10/2013

Returns: A pointer to the new Slider object

Note: If you subclass Slider, you MUST overload this method yourself! If you don't and/or your clone() method does not return an instance of your Slider subclass, you will experience "object slicing" when adding the widget to a window.

Warning: The caller must manage the memory for the returned Slider object.

Implements hdi::core::Widget.

◆ duplicate()

virtual Slider * hdi::core::Slider::duplicate ( ) const

virtual

Convenience method to duplicate a Slider object, creating a new and identical UI element to the target (but not belonging to the same containing window)

Author: GW

Date: 11/2013

Returns: A pointer to the new Slider object (and new UI element)

Warning: The caller must manage the memory for the returned Slider object.

Implements hdi::core::Widget.

◆ operator=()

virtual Slider & hdi::core::Slider::operator= ( const Slider & rhs_ )

virtual

Allows one Slider object to be assigned from another.

Author: GW

Date: 10/2013

Parameters

rhs_	Righthand side of the = operator; the object to copy values from

Returns: The target Slider object, but with its value updated to match that of rhs_

◆ setValue()

virtual void hdi::core::Slider::setValue ( const double value_ )

virtual

Sets the current value of the slider.

Author: GW

Date: 09/2013

Parameters

value_ New slider value in the range [0.0, 1.0]

Note: The provided value will be forced within the range [0.0, 1.0]

◆ setValueChangingCallback()

virtual void hdi::core::Slider::setValueChangingCallback ( const Callback & callback_ )

virtual

Sets the value changing callback.

Author: GW

Date: 09/2013

Parameters

callback_ New callback for when the slider's value is changing

◆ value()

virtual double hdi::core::Slider::value ( ) const

virtual

Gets the current value of the slider.

Author: GW

Date: 09/2013

Returns: The current value of the target Slider object, in range [0.0, 1.0]

◆ valueChanging()

virtual void hdi::core::Slider::valueChanging ( )

virtual

Simulates the value of the slider changing.

Author: GW

Date: 09/2013

◆ valueChangingCallback()

virtual Callback *const hdi::core::Slider::valueChangingCallback ( ) const

virtual

Gets the value changing callback for the slider.

Author: GW

Date: 09/2013

Returns: A pointer to the currently registered value changing callback
