TdxPDFDocument.OnSearchProgress Event
Enables you to track the progress of a time-consuming text search operation in the PDF document.
Declaration
property OnSearchProgress: TdxPDFDocumentTextSearchProgressEvent read; write;
Remarks
Handle the OnSearchProgress
event to display a progress bar in your application (the TcxProgressBar control, for instance) during a text search operation. This event can occur multiple times per search operation, every time the FindText method finishes processing a document page.
Example
You can use the APercent
parameter to obtain the percentage value that indicates the progress of the save operation:
TMyForm.SearchProgress(Sender: TdxPDFDocument; APageIndex: Integer; APercent: Integer);
begin
cxProgressBar1.Position := APercent;
end;
Refer to the TdxPDFDocumentTextSearchProgressEvent procedural type description for detailed information on parameters accessible within an OnSearchProgress
event handler.
Note
The TdxPDFViewer control handles the OnSearchProgress
event for its Document. If you work with the PDF Viewer, handle the TdxPDFViewer control’s OnSearchProgress event.
