| wxObject ()
| Default ctor; initializes to nullptr the internal reference data. More...
| wxObject (const wxObject &other)
| Copy ctor. More...
virtual | ~wxObject ()
| Destructor. More...
virtual wxClassInfo * | GetClassInfo () const
| This virtual function is redefined for every class that requires run-time type information, when using the wxDECLARE_CLASS macro (or similar). More...
wxObjectRefData * | GetRefData () const
| Returns the wxObject::m_refData pointer, i.e. the data referenced by this object. More...
bool | IsKindOf (const wxClassInfo *info) const

## Member Enumeration Documentation

## ◆ anonymous enum

anonymous enum

number of custom colours we store

Enumerator
NUM_CUSTOM |

## Constructor & Destructor Documentation

## ◆ wxColourData()

wxColourData::wxColourData | ( |  | ) |

Constructor.

Initializes the custom colours to `wxNullColour`, the data colour setting to black, and the choose full setting to true.

## ◆ ~wxColourData()

virtual wxColourData::~wxColourData | ( |  | ) |
| virtual

Destructor.

## Member Function Documentation

## ◆ FromString()

bool wxColourData::FromString | ( | const wxString & | str | ) |

Decodes the given string, which should be in the same format returned by ToString(), and sets the internal colours.

## ◆ GetChooseAlpha()

bool wxColourData::GetChooseAlpha | ( |  | ) | const

Indicates whether the colour dialog will display alpha values and an opacity selector.

It is meaningful under wxGTK, wxOSX and with regards to generic colour dialog.

The default value is false, except wxOSX where it is true (for the sake of backward compatibility).

## ◆ GetChooseFull()

bool wxColourData::GetChooseFull | ( |  | ) | const

Under Windows, determines whether the Windows colour dialog will display the full dialog with custom colour selection controls.

Has no meaning under other platforms.

The default value is true.

## ◆ GetColour()

wxColour& wxColourData::GetColour | ( |  | ) |

Gets the current colour associated with the colour dialog.

The default colour is black.

## ◆ GetCustomColour()

wxColour wxColourData::GetCustomColour | ( | int | i | ) | const

Returns custom colours associated with the colour dialog.

Parameters

  i | An integer between 0 and 15, being any of the 15 custom colours that the user has saved. The default custom colours are invalid colours.

## ◆ operator=()

wxColourData& wxColourData::operator= | ( | const wxColourData & | data | ) |

Assignment operator for the colour data.

## ◆ SetChooseAlpha()

void wxColourData::SetChooseAlpha | ( | bool | flag | ) |

Tells the colour dialog to show alpha values and an opacity selector (slider).

Currently it has effect under wxGTK, wxOSX and for generic colour dialog.

The default value is false, except wxOSX where it is true for backward compatibility.

## ◆ SetChooseFull()

void wxColourData::SetChooseFull | ( | bool | flag | ) |

Under Windows, tells the Windows colour dialog to display the full dialog with custom colour selection controls.

Under other platforms, has no effect.

The default value is true.

## ◆ SetColour()

void wxColourData::SetColour | ( | const wxColour & | colour | ) |

Sets the default colour for the colour dialog.

The default colour is black.

## ◆ SetCustomColour()

void wxColourData::SetCustomColour | ( | int | i,
|  | const wxColour & | colour
| ) |  |

Sets custom colours for the colour dialog.

Parameters

  i | An integer between 0 and 15 for whatever custom colour you want to set. The default custom colours are invalid colours.
  colour | The colour to set

## ◆ ToString()

wxString wxColourData::ToString | ( |  | ) | const

Converts the colours saved in this class in a string form, separating the various colours with a comma.
