Summary

Measure an item.


Pascal

 functionMeasureItem(ACanvas: TCanvas; Item: IJvDataItem): 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.
Item: IJvDataItem The Data Item to measure.


Description

MeasureItem measures the item specified by the Item 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.
