Summary

Measure an item given its index.

Pascal

 functionMeasureItemByIndex(ACanvas: TCanvas; Index: Integer): TSize;

Parameters

Parameters	Description
ACanvas: TCanvas	Canvas to measure on. On entry to this method it is assumed the canvas brush, pen and font are initialized to the proper values.
Index: Integer	Index into the items array of the item to measure.

Description

MeasureItemByIndex measures the item specified by the Index parameter. Depending on the implementation the method might first check if the item to measure supports the IJvDataItemRenderer interface; if it does, the measuring is handled by that interface instead.
The caller is responsible for initializing the canvas to the brush, pen and font color.
