Detailed Description

Base class for radio buttons.

Like all the "BaseXXXXX"-Classes, this serves primarily as base-class, from which you can derive your own customized objects. For a radio button implementation which uses images to visualize itself, please refer to CGUIRadioButton.

A radio button, like a check box, can have two states, 'selected' and 'not selected'. Radio buttons in addition must be children of a CGUIRadioButtonGroup. Only one of the radio buttons in a group can be selected at a time.

Example:

// Create base radio button.
CGUIBaseRadioButton *pkBaseRadioButton = new CGUIBaseRadioButton(
                                                 pkRadioButtonGroup, // parent must be a CGUIRadioButtonGroup
                                                 eC_FromInt(0), eC_FromInt(0),
                                                 eC_FromInt(60), eC_FromInt(20),
                                                 false, OBJ_BASERADIOBUTTON);

Constructor & Destructor Documentation

CGUIBaseRadioButton() [1/4]

CGUIBaseRadioButton::CGUIBaseRadioButton	(	CGUIRadioButtonGroup *const	pkParent,
		const eC_Value &	vX,
		const eC_Value &	vY,
		const eC_Value &	vWidth,
		const eC_Value &	vHeight,
		const eC_Bool &	bSelected = false,
		const ObjectHandle_t &	eID = NO_HANDLE
	)

CGUIBaseRadioButton constructor.

Parameters

pkParent	Pointer to parent object which must be a button group.
vX	X position relative to its parent object.
vY	Y position relative to its parent object.
vWidth	Width of the checkbox.
vHeight	Height of the checkbox.
bSelected	Status of the radio button. Selected, if true, not selected, otherwise
eID	Object Identifier of this radio button

CGUIBaseRadioButton() [2/4]

CGUIBaseRadioButton::CGUIBaseRadioButton	(	CGUIRadioButtonGroup *const	pkParent,
		const CGUIRect &	kRect,
		const eC_Bool &	bSelected = false,
		const ObjectHandle_t &	eID = NO_HANDLE
	)

CGUIBaseRadioButton constructor.

Parameters

pkParent	Pointer to parent object which must be a button group.
kRect	Structure containing x- and y-coordinates as well as width and height.
bSelected	Status of the radio button. Selected if true, not selected otherwise.
eID	Object Identifier of this radio button

CGUIBaseRadioButton() [3/4]

CGUIBaseRadioButton::CGUIBaseRadioButton

(

const CGUIBaseRadioButton &

kSource

)

Copy-constructor of the CGUIBaseRadioButton class.

Parameters

kSource

Source object to be copied.

CGUIBaseRadioButton() [4/4]

CGUIBaseRadioButton::CGUIBaseRadioButton

(

)

Standard constructor.

See also

CGUIObject().

Member Function Documentation

DoClick()

eC_Bool CGUIBaseRadioButton::DoClick ( const eC_Value &  vAbsX, const eC_Value &  vAbsY  )

virtual

Must be implemented to avoid calling of DoClick() in CGUIBaseCheckBox base class. This is because the CGUIRadioButtonGroup should handle toggling the selection state of its children.

Parameters

vAbsX	X-position in screen coordinates where the click occurred
vAbsY	Y-position in screen coordinates where the click occurred

Returns

True The event has been handled.
False The event has not been handled. In this base implementation it always returns False.

Reimplemented from CGUIBaseCheckBox.

DoDraw()

eC_Bool CGUIBaseRadioButton::DoDraw ( )

virtual

Visualizes the object. It is forbidden to call SetRelXPos, SetRelYPos, SetWidth or SetHeight in DoDraw, i.e., it is not allowed to change the layout.

Returns

True if anything was drawn, False otherwise

Reimplemented from CGUIBaseCheckBox.

Reimplemented in CGUIRadioButton.

operator=()

CGUIBaseRadioButton & CGUIBaseRadioButton::operator=

(

const CGUIBaseRadioButton &

kSource

)

Operator= method of the CGUIBaseRadioButton class.

Parameters

kSource

Source object to be copied.

Returns

Copied object.

ReadFromStream()

virtual void CGUIBaseRadioButton::ReadFromStream ( )

virtual

Reads all object attributes from streaming file. Only for use with GUIFactory. GUIStreamingFileReader has to be set in CGUI::Init().

See also

CGUIFactory

Reimplemented from CGUIBaseCheckBox.

Reimplemented in CGUIRadioButton.

Select()

void CGUIBaseRadioButton::Select

(

)

Set radio button selection status true. If another radio button in the same group is selected, it will become unselected before.

WriteToStream()

virtual void CGUIBaseRadioButton::WriteToStream ( const eC_Bool  bWriteClassID = false )

virtual

Writes all object attributes to the streaming file. StreamWriter has to be initialized. Only for use with GUIStreamWriter.

Parameters

bWriteClassID

This flag is used to select if writing of ControlID, leading and trailing tags is performed. Only GUIStreamWriter and GUICompositeObject have to set this flag true.

See also

CGUIStreamWriter

Reimplemented from CGUIBaseCheckBox.

Reimplemented in CGUIRadioButton.
