Syntax

public class GObject : SafeHandle, IDisposable

Properties

IsInvalid

Gets a value indicating whether the handle is invalid.

Declaration

public override bool IsInvalid { get; }

Property Value

Type	Description
System.Boolean	true if the handle is not valid; otherwise, false.

Overrides

System.Runtime.InteropServices.SafeHandle.IsInvalid

RefCount

Get the reference count of object. Handy for debugging.

Declaration

public uint RefCount { get; }

Property Value

Type	Description
System.UInt32

Methods

ReleaseHandle()

Decreases the reference count of object. When its reference count drops to 0, the object is finalized (i.e. its memory is freed).

Declaration

protected override bool ReleaseHandle()

Returns

Type	Description
System.Boolean	true if the handle is released successfully; otherwise, in the event of a catastrophic failure, false.

Overrides

System.Runtime.InteropServices.SafeHandle.ReleaseHandle()

SignalConnect(String, Delegate, IntPtr)

Connects a callback function (callback) to a signal on this object.

Declaration

public uint SignalConnect(string detailedSignal, Delegate callback, IntPtr data = default(IntPtr))

Parameters

Type	Name	Description
System.String	detailedSignal	A string of the form "signal-name::detail".
System.Delegate	callback	The callback to connect.
System.IntPtr	data	Data to pass to handler calls.

Returns

Type	Description
System.UInt32	The handler id.

Remarks

The callback will be triggered every time this signal is issued on this instance.

Exceptions

Type	Condition
System.Exception	If it failed to connect the signal.
