GET_DATA Data Vector: _getMeasuring



Returns the measuring status


Syntax
Details

Syntax

CALL SEND (data-vector-id, '_getMeasuring', measuring);

Argument Type Description
measuring
C returns the measuring status:


'Y' the viewer is measuring the data


'N' the viewer is not measuring the data


Details

The _getMeasuring method is valid only if the viewer is a table editor.

Note that the viewer, not the model, sets the measuring status. The model simply queries the status but does not set it.

A measuring state set to 'Y' informs the model that the viewer is measuring its data to determine how large to make its cells. Similar to the printing status controlled by the _setPrinting and _getPrinting methods, the models do not usually need to concern themselves with this value unless the model has an unspecified number of rows or columns. If this is the case, the model needs to check this value when returning information to the viewer in the _getData method call so that it does not continue to return rows or columns while measuring occurs.
