AddControl([EditClass], Column, AutoFree)
| AddControl | Specifies an edit-in-place control. |
| EditClass | The label of the EditClass. If omitted, the specified column is not editable. |
| Column | An integer constant, variable, EQUATE, or expression that indicates the browse list column to edit with the specified editclass object. |
| AutoFree | A numeric constant, variable, EQUATE, or expression that indicates whether the BrowseClass.Kill method DISPOSEs of the editclass object. A zero (0) value leaves the object intact. A non-zero value DISPOSEs the object. |
The AddControl method specifies the EditClass that defines the edit-in-place control for the browse column. Use autofree with caution; you should only DISPOSE of memory allocated with a NEW statement. See the Language Reference for more information on NEW and DISPOSE.
The AddControl method also registers fields which will not be editable via edit-in-place. In this instance the EditClass parameter is omitted.
Implementation:
The InitControls and BrowseClass.AddEditControl methods call the AddControl method. The BrowseClass.AddEditControl method defines the editclass for a column not utilizing the default editclass.
The AddControl method ADDs a record containing the values of EditClass, Column, and AutoFree, to the EditQueue which is declared in ABEdit.INC as follows:
EditQueue QUEUE,TYPE
Field UNSIGNED
FreeUp BYTE
Control &EditClass
END
Example:
BrowseClass.AddEditControl PROCEDURE(EditClass EC,UNSIGNED Id,BYTE Free)
CODE
SELF.CheckEIP
SELF.EIP.AddControl(EC,Id,Free)
