## Constructor & Destructor Documentation

wxPropertyGridEvent::wxPropertyGridEvent | ( | wxEventType | commandType = `0`,
|  | int | id = `0` |
| ) |  |  |

Constructor.

wxPropertyGridEvent::wxPropertyGridEvent | ( | const wxPropertyGridEvent & | event | ) |

Copy constructor.

wxPropertyGridEvent::~wxPropertyGridEvent | ( |  | ) |

Destructor.

## Member Function Documentation

bool wxPropertyGridEvent::CanVeto | ( |  | ) | const

Returns true if you can veto the action that the event is signaling.

unsigned int wxPropertyGridEvent::GetColumn | ( |  | ) | const

Returns the column index associated with this event.

For the column dragging events, it is the column to the left of the splitter being dragged

wxPGProperty* wxPropertyGridEvent::GetMainParent | ( |  | ) | const

Returns highest level non-category, non-root parent of property for which event occurred.

Useful when you have nested properties with children.

Remarks:
  If immediate parent is root or category, this will return the property itself.

wxPGProperty* wxPropertyGridEvent::GetProperty | ( |  | ) | const

Returns property associated with this event.

Remarks:
  You should assume that this property can always be NULL. For instance, `wxEVT_PG_SELECTED` is emitted not only when a new property is selected, but also when selection is cleared by user activity.

wxString wxPropertyGridEvent::GetPropertyName | ( |  | ) | const

Returns name of the associated property.

Remarks:
  Property name is stored in event, so it remains accessible even after the associated property or the property grid has been deleted.

wxVariant wxPropertyGridEvent::GetPropertyValue | ( |  | ) | const

Returns value of the associated property.

Works for all event types, but for `wxEVT_PG_CHANGING` this member function returns the value that is pending, so you can call Veto() if the value is not satisfactory.

Remarks:
  Property value is stored in event, so it remains accessible even after the associated property or the property grid has been deleted.

  GetPropertyValue()

wxPGVFBFlags wxPropertyGridEvent::GetValidationFailureBehavior | ( |  | ) | const

Returns current validation failure flags.

void wxPropertyGridEvent::SetCanVeto | ( | bool | canVeto | ) |

Set if event can be vetoed.

void wxPropertyGridEvent::SetProperty | ( | wxPGProperty * | p | ) |

Changes the property associated with this event.

void wxPropertyGridEvent::SetValidationFailureBehavior | ( | wxPGVFBFlags | flags | ) |

Set override validation failure behaviour.

Only effective if Veto() was also called, and only allowed if event type is `wxEVT_PG_CHANGING`.

void wxPropertyGridEvent::SetValidationFailureMessage | ( | const wxString & | message | ) |

Sets custom failure message for this time only.

Only applies if wxPG_VFB_SHOW_MESSAGE is set in validation failure flags.

void wxPropertyGridEvent::Veto | ( | bool | veto = `true` | ) |

Call this from your event handler to veto action that the event is signaling.

You can only veto a shutdown if wxPropertyGridEvent::CanVeto() returns true.

Remarks:
  Currently only `wxEVT_PG_CHANGING` supports vetoing.

bool wxPropertyGridEvent::WasVetoed | ( |  | ) | const

Returns true if event was vetoed.
