Class GValue
Wrap NetVips.Internal.GValue in a C# class.
Implements
Inherited Members
Namespace: NetVips
Assembly: NetVips.dll
Syntax
public class GValue : IDisposableRemarks
This class wraps NetVips.Internal.GValue in a convenient interface. You can use instances of this class to get and set GObject properties.
On construction, NetVips.Internal.GValue is all zero (empty). You can pass it to a get function to have it filled by GObject, or use init to set a type, set to set a value, then use it to set an object property.
GValue lifetime is managed automatically.

Get()
Get the contents of a GValue.
Declaration
public object Get()Returns
| Type | Description |
|---|---|
| object | The contents of this GValue. |
Remarks
The contents of the GValue are read out as a C# type.
GetTypeOf()
Get the GType of this GValue.
Declaration
public nint GetTypeOf()Returns
| Type | Description |
|---|---|
| nint | The GType of this GValue. |
Set(object)
Set a GValue.
Declaration
public void Set(object value)Parameters

|---|---|---|
| object | value | Value to be set. |
Remarks
The value is converted to the type of the GValue, if possible, and assigned.
