Detailed Description

Divider class for UI divider lines.

Constructor & Destructor Documentation

◆ Divider() [1/3]

hdi::core::Divider::Divider ( )

Constructs an empty Divider object.

Author: GW

Date: 09/2013

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

◆ Divider() [2/3]

hdi::core::Divider::Divider ( const Divider & div_ )

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

Author: GW

Date: 09/2013

Parameters

div_	Existing Divider object

◆ Divider() [3/3]

hdi::core::Divider::Divider	(	const Point &	loc_,
		const double	length_,
		const Direction	dir_ = `Horizontal`
	)

Constructs a divider line widget.

Author: GW

Date: 09/2013

Parameters

loc_	Top-left of the divider, in 1x resolution coordinates
length_	Length of the divider
dir_	Horizontal or vertical line?

◆ ~Divider()

virtual hdi::core::Divider::~Divider ( )

virtual

Divider destructor.

Author: GW

Date: 09/2013

Member Function Documentation

◆ clone()

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

virtual

Convenience method to clone a Divider object on the heap.

Author: GW

Date: 10/2013

Returns: A pointer to the new Divider object

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

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

Implements hdi::core::Widget.

◆ direction()

virtual Direction hdi::core::Divider::direction ( ) const

virtual

Gets the direction that the line is going.

Author: GW

Date: 09/2013

Returns: Vertical for a vertical line, Horizontal otherwise

◆ duplicate()

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

virtual

Convenience method to duplicate a Divider 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 Divider object (and new UI element)

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

Implements hdi::core::Widget.

◆ enabled()

virtual bool hdi::core::Divider::enabled ( )

virtual

Returns true, because dividers are always enabled.

Author: GW

Date: 09/2013

Returns: true

Reimplemented from hdi::core::Widget.

◆ operator=()

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

virtual

Allows one Divider 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 Divider object, but with its value updated to match that of rhs_

◆ setEnabled()

virtual void hdi::core::Divider::setEnabled ( const bool enable_ )

virtual

Overrides Widget::setEnabled() because dividers are always enabled.

Author: GW

Date: 09/2013

Parameters

enable_ true to enable, false to disable (ignored)

Reimplemented from hdi::core::Widget.

◆ setText()

virtual void hdi::core::Divider::setText ( const std::string & )

virtual

Prevents setting the text, as dividers cannot have text.

Author: GW

Date: 09/2013

Reimplemented from hdi::core::Widget.

◆ text()

virtual std::string hdi::core::Divider::text ( ) const

virtual

Always gets "", as dividers cannot have text.

Author: GW

Date: 09/2013

Returns: ""

Reimplemented from hdi::core::Widget.

◆ type()

virtual Type hdi::core::Divider::type ( ) const

virtual

Returns DividerType, as dividers are always dividers!

Author: GW

Date: 09/2013

Returns: DividerType

Reimplemented from hdi::core::Widget.
