Description

function BeginUpdate: integer;

each call to BeginUpdate increments an internal counter that prevents from repainting (see also EndUpdate)

function CanCopy: boolean;

is copying to clipboard possible?

function CanCreateUndo(const aKind: TMPHUndoFlag; const aCount, aReplCount: integer): Boolean; override;

Protected-Deklarationen

function CanCut: boolean;

is cutting to clipboard possible?

function CanPaste: boolean;

is pasting from clipboard possible?

function CBCopy: boolean;

copy selection to clipboard

function CBCut: boolean;

cut selection to clipboard

function CBPaste: boolean;

paste clipboard's contents over current selection

function CreateRangeUndo(const aStart, aCount: integer; sDesc: string): boolean;

create an undo for a range of bytes

function EndUpdate: integer;

each call to EndUpdate decrements an internal counter that prevents from repainting. the return value is the value of this counter. if the counter is reset to zero, repainting is permitted again (see also BeginUpdate)

function OwnsClipBoard: boolean;

do we own the clipboard data?

procedure PasteData(P: Pointer; const ACount: integer; const UndoDesc: string = '');

paste data (in clipboardmanner: check current selection and so on)

procedure Print(const Page: integer);

print the given page to the default printer. Printer.BeginDoc, Printer.NewPage and Printer.EndDoc must be issued by the caller!

function PrintNumPages: integer;

get the number of pages to print

function PrintPreview(const Page: integer): TMetaFile;

creates a TMetaFile object and renders the specified page on its canvas. Freeing of the TMetaFile is up to the caller!

procedure ReleaseClipboard(const Flush: boolean);

flush or empty the clipboard (if we own the IDataObject)

procedure Save;

save to file (overwrite)

function UndoBeginUpdate(const StrUndoDesc: string=''): integer; reintroduce;

each call to UndoBeginUpdate increments an internal counter that prevents using undo storage and also disables undo functionality (see also UndoEndUpdate)

function UndoEndUpdate: integer; override;

each call to UndoEndUpdate decrements an internal counter that prevents using undo storage and also disables undo functionality. the return value is the value of this counter. if the counter is reset to zero, undo creation is permitted again (see also UndoBeginUpdate)

procedure WriteBuffer(const Buffer; const Index, Count: Integer); override;
