AutoSize Method

Objective-C
Java
C++

public virtual void AutoSize()

'Declaration
 
Public Overridable Sub AutoSize()

'Usage
 
Dim instance As AnnTextObject
 
instance.AutoSize()

public:
virtual void AutoSize();

Call this method to change the bounds (AnnTextObject.Bounds) value to closely fit its contents. The control will automatically add the correct space around the text for the current font style and size leading and takes into consideration the border size.

When using automation, setting the value of the AnnTextEditDesigner.AutoSizeAfterEdit property to true will result in the toolkit calling the AnnTextObject.AutoSize to adjust the object.
