To create text paths simply use the TWPRTFStorage component.

 

In its property 'Links' you have to create an item for each TWPRichText in the chain.

 

 

The following initialization is required:

 

procedure TWPTextPathDemo.FormCreate(Sender: TObject);

begin

// All path objects need the window handle - otherwise we cannot

// use our broadcasting system

WPRichText1.HandleNeeded;

WPRichText2.HandleNeeded;

WPRichText3.HandleNeeded;

WPRichText4.HandleNeeded;

 

WPRichText1.InputString('This is a text path. Please create new pages with Ctrl+CR'+#13);

WPRichText1.CPPosition := MaxInt;

// Settings for all TWPRichText

WPRichText1.EditBoxModes := [wpemLimitTextWidth,wpemLimitTextHeight];

WPRichText1.EditOptions := [wpNoHorzScrolling,wpNoVertScrolling];

 

WPRichText2.EditBoxModes := [wpemLimitTextWidth,wpemLimitTextHeight];

WPRichText2.EditOptions := [wpNoHorzScrolling,wpNoVertScrolling];

 

WPRichText3.EditBoxModes := [wpemLimitTextWidth,wpemLimitTextHeight];

WPRichText3.EditOptions := [wpNoHorzScrolling,wpNoVertScrolling];

 

WPRichText4.EditBoxModes := [wpemLimitTextWidth,wpemLimitTextHeight];

WPRichText4.EditOptions := [wpNoHorzScrolling,wpNoVertScrolling];  

end;

 

 

In the BeforeEditBoxNeedFocus event we use this code:

 

procedure TWPTextPathDemo.WPRichText1BeforeEditBoxNeedFocus(Sender: TObject;

var Abort: Boolean);

begin

 PageControl1.ActivePageIndex := 0;

end;

 

procedure TWPTextPathDemo.WPRichText3BeforeEditBoxNeedFocus(Sender: TObject;

var Abort: Boolean);

begin

 PageControl1.ActivePageIndex := 1;

end;

 

In the OnMouseDown event of the page control we remove the focus from the editors:

 

procedure TWPTextPathDemo.PageControl1MouseDown(Sender: TObject;

 Button: TMouseButton; Shift: TShiftState; X, Y: Integer);

begin

// The WPRichText must loose the focus - otherwise it is not possible

// to switch to a different page

 PageControl1.SetFocus;

end;
