TSRichViewEdit.RangeSearch

Allows to narrow a search scope.

RangeSearch: Boolean;

If it is True, the search is performed only in items located between coordinates specified in RangeSearchFirstY..RangeSearchLastY properties.

This range affects the following methods:

•FindPriorItem, FindNextItem,

•FindPriorHyperlink, FindNextHyperlink,

•FindPriorCheckpoint, FindNextCheckpoint,

•PriorCurItem, NextCurItem,

•PriorCurHyperlink, NextCurHyperlink,

•PriorCurCheckpoint, NextCurCheckpoint.

This feature can be used, for example, to search only on the some pages.

Example: searching for the first visible hyperlink (if any hyperlink is visible):

var

  RVData: TCustomRVData;

  RVData2: TCustomRVFormattedData;

  ItemNo, OffsetInItem: Integer;

..

SRichViewEdit1.RangeSearch := True;

SRichViewEdit1.RangeSearchFirstY := 0;

SRichViewEdit1.RangeSearchLastY := SRichViewEdit1.ClientHeight;

SRichViewEdit1.GetFirstItemVisibleRV(RVData2, ItemNo, OffsetInItem);

RVData := RVData2;

Dec(ItemNo);

if FindNextHyperlink(RVData, ItemNo) then
