TCustomImageList.ReadData procedure

Declaration

procedure ReadData(AStream: TStream); virtual

Arguments

Description

ReadData is a procedure used to read image data for the default resolution from the stream specified in AStream. ReadData allows image data written using the WriteData method to be stored in the image list.

ReadData calls BeginUpdate to suspend OnChange notifications when loading the image data from the stream. EndUpdate is called when the image data has been loaded from the stream.

ReadData calls the GetResolution method to locate the TCustomImageListResolution class instance which uses the image width in the Width property. The ReadData method in TCustomImageListResolution is used to read image data from the stream in AStream.

ReadData updates the internal Changed flag for the image list, and calls the Change method to perform change notifications.
