Leadtools.Annotations Namespace > AnnTextObject Class : AutoSize Method |
public virtual void AutoSize()
'Declaration Public Overridable Sub AutoSize()
'Usage Dim instance As AnnTextObject instance.AutoSize()
public virtual void AutoSize()
function Leadtools.Annotations.AnnTextObject.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.
