Method TBrowse():getColumn() Foundation

Retrieves a reference to a column (TBColumn object ) in a TBrowse object.

:getColumn( <nColPos> ) --> oTBColumn
<nColPos> is a numeric value which indicates which TBColumn object reference is required.

:getColumn() returns a reference to the TBColumn object held in position <nColPos>.


When the numeric value <nColPos> is passed to the method :getColumn(), the TBrowse object returns a reference to the corresponding column object. Using the reference, changes to the column can be made that also update the column definition stored with the TBrowse. However, such changes are not immediately realized. Only when the TBrowse is notified explicitly through a :configure(), :invalidate(), or :refreshAll() (and then only after the next stabilization) will the changes to the column be visible.
