LIST OBJECTS Command
Continuously displays information about an object or a group of objects.
LIST OBJECTS [LIKE cObjectSkeleton] [TO PRINTER [PROMPT] | TO FILE FileName [ADDITIVE]] [NOCONSOLE]
- LIKE cObjectSkeleton
Displays information about a subset of objects. cObjectSkeleton is an object specification skeleton that supports wildcards (* and ?). For example, to continuously display all objects that begin with A, use the following command:
LIST OBJECTS LIKE A*
- TO PRINTER [PROMPT]
Directs output from LIST OBJECTS to a printer.
You can include the optional PROMPT clause to display a Print dialog box before printing starts. Place the PROMPT keyword immediately after TO PRINTER.
- TO FILE FileName
Directs output from LIST OBJECTS to the disk file specified with FileName. If the file already exists and SET SAFETY is ON, Visual FoxPro displays a prompt asking if you want to overwrite the file.
Appends to the end of the named file. If you omit ADDITIVE, then the file is overwritten with the value of the expression.
Suppresses output to the main Visual FoxPro window or to the active user-defined window.
LIST OBJECTS displays the following information about all existing objects:
Properties and their values.
Member objects and the class or subclass on which they are based.
Class or subclass on which objects are based.
Class hierarchy for the objects.
LIST OBJECTS fills the entire main Visual FoxPro window without pausing.
The following example uses DEFINE CLASS and CREATEOBJECT( ) to create two custom classes named FormChild and FormGrandChild from the Visual FoxPro Form base class. LIST OBJECTS lists information about the objects and their properties.
CLEAR frmMyForm = CREATEOBJECT("FormGrandChild") LIST OBJECTS LIKE frm* RELEASE frmMyForm DEFINE CLASS FormChild AS FORM ENDDEFINE DEFINE CLASS FormGrandChild AS FormChild ENDDEFINE
