# wxPGChoices Class Reference
[wxPropertyGrid]

`#include </home/work/projects/wx/2.9/wx/interface/wx/propgrid/property.h>`

## Detailed Description

Helper class for managing choices of wxPropertyGrid properties.

Each entry can have label, value, bitmap, text colour, and background colour.

wxPGChoices uses reference counting, similar to other wxWidgets classes. This means that assignment operator and copy constructor only copy the reference and not the actual data. Use Copy() member function to create a real copy.

Remarks:
  If you do not specify value for entry, index is used.

Default constructor.

wxPGChoices::wxPGChoices | ( | const wxPGChoices & | a | ) |

Copy constructor, uses reference counting.

To create a real copy, use Copy() member function instead.

wxPGChoices::wxPGChoices | ( | const wxChar ** | labels,
|  | const long * | values = `NULL` |
| ) |  |  |

Constructor.

wxPGChoices::wxPGChoices | ( | const wxArrayString & | labels,

## Member Function Documentation

void wxPGChoices::Add | ( | const wxChar ** | labels,
|  | const ValArrItem * | values = `NULL` |
| ) |  |  |

Adds to current.

If did not have own copies, creates them now. If was empty, identical to set except that creates copies.

void wxPGChoices::Add | ( | const wxArrayString & | arr,
|  | const ValArrItem * | values = `NULL` |
| ) |  |  |

Version that works with wxArrayString.

wxPGChoiceEntry& wxPGChoices::Add | ( | const wxString & | label,
|  | int | value = `wxPG_INVALID_VALUE` |
| ) |  |  |

Adds single item.

wxPGChoiceEntry& wxPGChoices::Add | ( | const wxString & | label,
|  | const wxBitmap & | bitmap,
|  | int | value = `wxPG_INVALID_VALUE` |
| ) |  |  |

Adds a single item, with bitmap.

void wxPGChoices::Add | ( | const wxArrayString & | arr,
|  | const wxArrayInt & | arrint |
| ) |  |  |
