+ Inheritance diagram for wxVariant:

Detailed Description

The wxVariant class represents a container for any type.

A variant's value can be changed at run time, possibly to a different type of value.

Note
As of wxWidgets 2.9.1, wxAny has become the preferred variant class. While most controls still use wxVariant in their interface, you can start using wxAny in your code because of an implicit conversion layer. See below for more information.

As standard, wxVariant can store values of type bool, wxChar, double, long, string, string list, time, date, void pointer, list of strings, and list of variants. However, an application can extend wxVariant's capabilities by deriving from the class wxVariantData and using the wxVariantData form of the wxVariant constructor or assignment operator to assign this data to a variant. Actual values for user-defined types will need to be accessed via the wxVariantData object, unlike the case for basic data types where convenience functions such as GetLong() can be used.

Under Microsoft Windows, three additional wxVariantData-derived classes – wxVariantDataCurrency, wxVariantDataErrorCode and wxVariantDataSafeArray – are available for interoperation with OLE VARIANT when using wxAutomationObject.

Pointers to any wxObject derived class can also easily be stored in a wxVariant. wxVariant will then use wxWidgets' built-in RTTI system to set the type name (returned by GetType()) and to perform type-safety checks at runtime.

This class is useful for reducing the programming for certain tasks, such as an editor for different data types, or a remote procedure call protocol.

An optional name member is associated with a wxVariant. This might be used, for example, in CORBA or OLE automation classes, where named parameters are required.

Note that as of wxWidgets 2.7.1, wxVariant is reference counted. Additionally, the convenience macros DECLARE_VARIANT_OBJECT() and IMPLEMENT_VARIANT_OBJECT() were added so that adding (limited) support for conversion to and from wxVariant can be very easily implemented without modifying either wxVariant or the class to be stored by wxVariant. Since assignment operators cannot be declared outside the class, the shift left operators are used like this:

// in the header file
DECLARE_VARIANT_OBJECT(MyClass)
// in the implementation file
IMPLEMENT_VARIANT_OBJECT(MyClass)
// in the user code
wxVariant variant;
MyClass value;
variant << value;
// or
value << variant;

For this to work, MyClass must derive from wxObject, implement the wxWidgets RTTI system and support the assignment operator and equality operator for itself. Ideally, it should also be reference counted to make copying operations cheap and fast. This can be most easily implemented using the reference counting support offered by wxObject itself. By default, wxWidgets already implements the shift operator conversion for a few of its drawing related classes:

IMPLEMENT_VARIANT_OBJECT(wxColour)
IMPLEMENT_VARIANT_OBJECT(wxImage)
IMPLEMENT_VARIANT_OBJECT(wxIcon)
IMPLEMENT_VARIANT_OBJECT(wxBitmap)

Note that as of wxWidgets 2.9.0, wxVariantData no longer inherits from wxObject and wxVariant no longer uses the type-unsafe wxList class for list operations but the type-safe wxVariantList class. Also, wxVariantData now supports the wxVariantData::Clone() function for implementing the Unshare() function. wxVariantData::Clone() is implemented automatically by IMPLEMENT_VARIANT_OBJECT().

Since wxVariantData no longer derives from wxObject, any code that tests the type of the data using wxDynamicCast() will require adjustment. You can use the macro wxDynamicCastVariantData() with the same arguments as wxDynamicCast(), to use C++ RTTI type information instead of wxWidgets RTTI.

wxVariant to wxAny Conversion Layer

wxAny is a more modern, template-based variant class. It is not directly compatible with wxVariant, but there is a transparent conversion layer.

Following is an example how to use these conversions with wxPropertyGrid's property class wxPGProperty (which currently uses wxVariants both internally and in the public API):

// Get property value as wxAny instead of wxVariant
wxAny value = property->GetValue();
// Do something with it
DoSomethingWithString(value.As<wxString>());
// Write back new value to property
value = "New Value";
property->SetValue(value);

Some caveats:

  • In wxAny, there are no separate types for handling integers of different sizes, so converting wxAny with 'long long' value will yield wxVariant of "long" type when the value is small enough to fit in without overflow. Otherwise, variant type "longlong" is used. Also note that wxAny holding unsigned integer will always be converted to "ulonglong" wxVariant type.
  • Unlike wxVariant, wxAny does not store a (rarely needed) name string.
  • Because of implicit conversion of wxVariant to wxAny, wxAny cannot usually contain value of type wxVariant. In other words, any.CheckType<wxVariant>() can never return true.

Supplied conversion functions will automatically work with all built-in wxVariant types, and also with all user-specified types generated using IMPLEMENT_VARIANT_OBJECT(). For hand-built wxVariantData classes, you will need to use supplied macros in a following manner:

// Declare wxVariantData for data type Foo
class wxVariantDataFoo: public wxVariantData
{
public:
// interface
// ...
DECLARE_WXANY_CONVERSION()
protected:
// data storage etc
// ...
};
IMPLEMENT_TRIVIAL_WXANY_CONVERSION(Foo, wxVariantDataFoo)

Destructor.

Note
wxVariantData's destructor is protected, so wxVariantData cannot usually be deleted. Instead, wxVariantData::DecRef() should be called. See reference-counted object destruction for more info.

const wxString& wxVariant::GetName ( ) const

Returns a constant reference to the variant name.

wxString wxVariant::GetString ( ) const

wxString wxVariant::GetType ( ) const

Returns the value type as a string.

The built-in types are:

  • "bool"
  • "char"

  • "double"
  • "list"
  • "long"
  • "longlong"
  • "string"
  • "ulonglong"

wxULongLong wxVariant::GetULongLong ( ) const

Returns the unsigned 64-bit integer value.

void* wxVariant::GetVoidPtr ( ) const

Gets the void pointer value.

Notice that this method can be used for null objects (i.e. those for which IsNull() returns true) and will return NULL for them.

wxObject* wxVariant::GetWxObjectPtr ( ) const

Gets the wxObject pointer value.

void wxVariant::Insert ( const wxVariant value)

Inserts a value at the front of the list.

bool wxVariant::IsNull ( ) const
