Name
Cursor
Synopsis
This class wraps a Win32 cursor—the image that represents the
mouse pointer. Cursor
is a slightly curious class
in that it wraps up both GDI-like functionality and global system
cursor/pointer behavior.
Unlike Win32, .NET cursors are static images—you cannot create
them from animations. You can, however, create cursors from COM
IPicture
objects, files and streams, and Win32
cursor handles. You can also retrieve a Win32 handle using the
Handle
property, or get a copy of the underlying
Win32 object with the CopyHandle()
method.
Predefined cursors are available as static properties on the
Cursors
class.
Similar to most of the System.Drawing
objects,
Cursor
objects are a scarce system resource, and
therefore you should manage their lifetimes carefully, calling
Dispose()
when you are finished to release the
resources back to the OS. Also in keeping with the drawing objects,
you can paint the cursor imagery on a
System.Drawing.Graphics
surface using the
Draw( )
and DrawStretched()
methods. The object’s dimensions can be obtained
from the Size
property.
Each Control
object has a
Cursor
property, which you can use to the set the
default cursor shown while the mouse is over the control. You can
also temporarily set the cursor to something else (such as the
Cursors.WaitCursor
) by using the static
Current
property. This overrides any other
settings until you either set the Current
value
back to Cursors.Default
or call the
DoEvents()
method.
