<< Click to display table of contents >> TCustomRichView.InsertRVFFromStream |
Inserts RVF content from Stream at the position of the document specified as Index (the first inserted item will have this index)
function InsertRVFFromStream(Stream: TStream; Index: Integer): Boolean;
This is the only method of RichView (not RichViewEdit) inserting items in any position.
Index – index of the item, must be in range from 0 to ItemCount. Items of subdocuments (table cells) are not included in the items range of the main document.
Method type: viewer-style.
Setting for RVF loading can be changed in the TRichView component editor.
If style templates are used, and RVFTextStylesReadMode=RVFParaStylesReadMode=rvf_sInsertMerge, and StyleTemplateInsertMode<>rvstimIgnoreSourceStyleTemplates, the method merges style templates from RVF into Style.StyleTemplates, and reads text and paragraph styles according to StyleTemplateInsertMode. The method calls OnStyleTemplatesChange event.
Return value: "Was reading successful?"
This example shows how to combine several RVF documents in one. procedure AddDoc(const FileName: String; rv: TCustomRichView); var Stream: TFileStream; begin Stream := TFileStream.Create(FileName, fmOpenRead); rv.InsertRVFFromStream(Stream, rv.ItemCount); Stream.Free; end; ... RichView1.Clear; RichView1.DeleteUnusedStyles(True, True, True); AddDoc('c:\file1.rvf', RichView1); AddDoc('c:\file2.rvf', RichView1); AddDoc('c:\file3.rvf', RichView1); RichView1.Format; If you want to add page breaks between documents, use the following code procedure AddDoc(const FileName: String; rv: TCustomRichView); var Stream: TFileStream; ItemCount: Integer; begin ItemCount := rv.ItemCount; Stream := TFileStream.Create(FileName, fmOpenRead); rv.InsertRVFFromStream(Stream, rv.ItemCount); Stream.Free; if (ItemCount>0) and (ItemCount<rv.ItemCount) then rv.PageBreaksBeforeItems[ItemCount] := True; end; |
