Searches for an object in one or more PowerBuilder libraries (PBLs) and provides information about its class definition.
FindClassDefinition ( classname {, librarylist } )
Argument |
Description |
|---|---|
classname |
The name of an object (also called a class or class definition) for which you want information. |
librarylist (optional) |
An array of strings whose values are the fully qualified pathnames of PBLs. If you omit librarylist, FindClassDefinition searches the library list associated with the running application. |
ClassDefinition. Returns an object reference with information about the definition of classname. If any arguments are null, FindClassDefinition returns null.
There are two ways to get a ClassDefinition object containing class definition information:
For an instantiated object in your application, use its ClassDefinition property
For an object stored in a PBL, call FindClassDefinition
This example searches the libraries for the running application to find the class definition for w_genapp_frame:
ClassDefinition cd_windef
cd_windef = FindClassDefinition("w_genapp_frame")
This example searches the libraries in the array ls_libraries to find the class definition for w_genapp_frame:
ClassDefinition cd_windef
string ls_libraries[ ]
ls_libraries[1] = "c:\pwrs\bizapp\windows.pbl"
ls_libraries[2] = "c:\pwrs\framewk\windows.pbl"
ls_libraries[3] = "c:\pwrs\framewk\ancestor.pbl"
cd_windef = FindClassDefinition(
"w_genapp_frame", ls_libraries)
