## Detailed Description

a vertical switch control

Define a switch with a given number of positions, the current position is defined by the position of the last click on this object (the object is divided in its height by the number of position). Each position has its subbitmap, each subbitmap is stacked in the given handle bitmap. By clicking Alt+Left Mouse the default value is used. Use a CMultiFrameBitmap for its background bitmap.

|  | CBitmap * | background
| ) |  |

CVerticalSwitch constructor.

Parameters

  size | the size of this view
  listener | the listener
  tag | the control tag
  background | the switch bitmap
  offset | unused

## ◆ CVerticalSwitch() [2/3]

CVerticalSwitch | ( | const CVerticalSwitch & | vswitch | ) |

## ◆ CVerticalSwitch() [3/3]

CVerticalSwitch | ( | const CRect & | size,

|  | int32_t | tag,
|  | int32_t | subPixmaps,
|  | CCoord | heightOfOneImage,
|  | int32_t | iMaxPositions,
|  | CBitmap * | background,
|  | const CPoint & | offset = `CPoint (0, 0)`
| ) |  |

CVerticalSwitch constructor.

Parameters

  size | the size of this view
  listener | the listener
  tag | the control tag
  subPixmaps | number of sub bitmaps in background
  heightOfOneImage | height of one sub bitmap
  iMaxPositions | TODO

## ◆ ~CVerticalSwitch()

~CVerticalSwitch | ( |  | ) |
| override protected default noexcept

## Member Function Documentation

## ◆ calcNormFromPoint()

float calcNormFromPoint | ( | const CPoint & | where | ) | const
| override protected virtual

Implements CSwitchBase.

## ◆ calculateCoef()

double calculateCoef | ( |  | ) | const
| override protected virtual

Implements CSwitchBase.

## ◆ newCopy()

CBaseObject * newCopy | ( |  | ) | const
| inline override virtual
