Occurs when drawing page breaks. property OnDrawPageBreak: TRVDrawPageBreakEvent;
type TRVPageBreakType = (rvpbSoftPageBreak, rvpbPageBreak);
TRVDrawPageBreakEvent = procedure (Sender: TRVStyle; Canvas: TCanvas; Y, XShift: Integer; PageBreakType: TRVPageBreakType; Control: TControl; var DoDefault: Boolean) of object; (introduced in version 1.3; modified in 1.7) You can use this event to draw your own visual representation of page breaks. This event occurs only if rvoShowPageBreaks is included in TCustomRichView(Control).Options. Input parameters: Sender – TRVStyle generating the event. Canvas – canvas to paint. PageBreakType – type of page break (either soft (automatic) page break or explicit (user-defined) page break). Y – y coordinate of page break in TRichView window. XShift – how much TRichView is scrolled horizontally (>=0). Control – TRichView control. DoDefault is equal to True.
"Hidden" input parameters: Sender.RVData: TPersistent, document where page break occurs. It should be typecasted to TCustomRVFormattedData before using. Sender.ItemNo: Integer, index of the item in Sender.RVData. These parameters define one of the following: ▪item starting a new page; ▪table with page breaks between rows.
Output parameter: DoDefault – set to False to prevent default drawing. The default procedure draws horizontal line horizontal line with "dog-ear" effect. The line color is either PageBreakColor or SoftPageBreakColor, depending on PageBreakType.
Using Sender.RVData you can get additional information about the item: For example: uses ..., CRVFData; ... var ParaNo: Integer; begin ParaNo := TCustomRVFormattedData(Sender.RVData).GetItemPara(Sender.ItemNo)); ... end;
