Detailed Description

A primitive-based radial slider.

radial_slider.png
The "radial slider" can control values in a radial manner.

Constructor & Destructor Documentation

◆ CGUIRadialSlider() [1/3]

CGUIRadialSlider::CGUIRadialSlider ( CGUICompositeObject *const  pParent,
const eC_Value &  vX,
const eC_Value &  vY,
const eC_Value &  vWidth,
const eC_Value &  vHeight,
const ObjectHandle_t eID = NO_HANDLE 
)

Constructor. By default, the progress bar type is set to be PBT_PROGRESSBAR_TYPE_NORMAL. The level range is from 0 to 100. The step size is set to 1 pixel. The dimension of the bar is determined after the foreground image is set. Here it is set to be 0 by 0.

Parameters
pParentPointer to parent object.
vXX position relative to its parent object.
vYY position relative to its parent object.
vWidthWidth of the control.
vHeightHeight of the control.
eIDobject handle for the control.

◆ CGUIRadialSlider() [2/3]

CGUIRadialSlider::CGUIRadialSlider ( CGUICompositeObject *const  pParent,
const CGUIRect kRect,
const ObjectHandle_t eID = NO_HANDLE 
)

Constructor. By default, the progress bar type is set to be PBT_PROGRESSBAR_TYPE_NORMAL. The level range is from 0 to 100. The step size is set to 1 pixel. The dimension of the bar is determined after the foreground image is set. Here it is set to be 0 by 0.

Parameters
pParentPointer to parent object.
kRectrectangle area
eIDobject handle for the control.

◆ CGUIRadialSlider() [3/3]

CGUIRadialSlider::CGUIRadialSlider ( const CGUIRadialSlider kSource)

Copy-constructor of the CGUIRadialSlider class.

Parameters
kSourceSource object to be copied.

Member Function Documentation

◆ CopyAttributes()

void CGUIRadialSlider::CopyAttributes ( const CGUIRadialSlider kSource)
protected

Copy attributes from source control to this control.

Parameters
kSourceSource object to be copied.

◆ DoButtonDown()

eC_Bool CGUIRadialSlider::DoButtonDown ( const eC_Value &  vAbsX,
const eC_Value &  vAbsY 
)
virtual

Called when the mouse button or finger is pressed down over an object.

Note
DoButtonDown() should work on the absolute positions of this object, that were set at the time of the passed redraw, as the user expects to click on what he sees and not to click on the object in a newer and probably intermediate state that he currently does not see in this state. Thus, to calculate the relative position (where the object was pressed relative to the origin of this object) from the vAbsY argument you must do it like this: vMyRelYPos = vAbsY - GetAbsYPos().
Parameters
vAbsXX-position in screen coordinates where the click occurred
vAbsYY-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 always returns False.

Reimplemented from CGUIBehaviour.

◆ DoClick()

eC_Bool CGUIRadialSlider::DoClick ( const eC_Value &  vAbsX,
const eC_Value &  vAbsY 
)
virtual

Called when the object receives a click event. A click can e.g., be the result of a mouse click, a finger press/release sequence on touchscreens, or be triggered by a GK_ACTION keyboard event.

Note
DoClick() should work on the absolute positions of this object, that were set at the time of the passed redraw, as the user expects to click on what he sees and not to click on an object in a newer and probably intermediate state that he currently does not see. Thus, to calculate the relative position (where the mouse button was pressed and released at the same position for in a certain time span, relative to the origin of this object) from the vAbsY argument you must do it like this: vMyRelYPos = vAbsY - GetAbsYPos().
Parameters
vAbsXX-position in screen coordinates where the click occurred
vAbsYY-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 CGUIBehaviour.

◆ DoDrag()

eC_Bool CGUIRadialSlider::DoDrag ( const eC_Value &  vDeltaX,
const eC_Value &  vDeltaY,
const eC_Value &  vAbsX,
const eC_Value &  vAbsY 
)
virtual

Called when the object receives a Drag event. Drags are typically created if the mouse is being used while a mouse-button is being pressed, or if the user moves his finger over a touchscreen.

Parameters
vDeltaXrelative movement in x-direction since the last call of DoDrag/ButtonDown
vDeltaYrelative movement in y-direction since the last call of DoDrag/ButtonDown
vAbsXcurrent X-position in screen coordinates of the mouse
vAbsYcurrent Y-position in screen coordinates of the mouse
Returns
True If the event has been handled.
false Else.

Reimplemented from CGUIBehaviour.

◆ DoDragEnd()

eC_Bool CGUIRadialSlider::DoDragEnd ( const eC_Value &  vAbsX,
const eC_Value &  vAbsY 
)
virtual

Called on the dragged object (=the object on which the initial ButtonDown-event occurred) when the mouse button is released after a drag event.

Parameters
vAbsXcurrent X-position in screen coordinates of the mouse
vAbsYcurrent Y-position in screen coordinates of the mouse
Returns
True If the event has been handled.
false Else.

Reimplemented from CGUIBehaviour.

◆ GetAngle()

eC_Value CGUIRadialSlider::GetAngle ( const eC_Value &  vAbsX,
const eC_Value &  vAbsY 
)
protected

Get the angle for a specific position

Parameters
vAbsXabsolute position for x
vAbsYabsolute position for y
Returns
angle

◆ Init()

void CGUIRadialSlider::Init ( )
protected

Help function to initialize the control.

◆ MoveHandle()

void CGUIRadialSlider::MoveHandle ( const eC_Value &  vDeltaX,
const eC_Value &  vDeltaY,
const eC_Value &  vAbsX,
const eC_Value &  vAbsY 
)
protected

Move the handle to a specific position

Parameters
vDeltaXdelta for x
vDeltaYdelta for y
vAbsXabsolute position for x
vAbsYabsolute position for y

◆ operator=()

CGUIRadialSlider & CGUIRadialSlider::operator= ( const CGUIRadialSlider kSource)

Operator= method of the CGUIRadialSlider class.

Parameters
kSourceSource object to be copied.
Returns
Copied object.

◆ ReadFromStream()

void CGUIRadialSlider::ReadFromStream ( )
virtual
