If you need to enable a user to change the contents of a document (web page) displayed by the TWebBrowser component, use the following trick:
~~~~~~~~~~~~~~~~~~~~~~~~~
uses MSHTML;
//Drop a TWebBrowser (name: WebBrowser1) on a form...
procedure TForm1.FormCreate(Sender: TObject) ;
begin
WebBrowser1.Navigate('http://delphi.about.com') ;
end;
//this handles the OnNavigateComplete event of WebBrowser1
procedure TForm1.WebBrowser1DocumentComplete(Sender: TObject;
const pDisp: IDispatch; var URL: OleVariant) ;
begin
((Sender as TWebBrowser).Document as IHTMLDocument2).designMode := 'on';
end;
~~~~~~~~~~~~~~~~~~~~~~~~~
Note: The IHTMLDocument2's designMode property is used to put WebBrowser into a mode where a user can edit the current document.
While the browser is in design mode, objects enter a UI-activated state when the user presses ENTER or clicks an object that has focus, or when the user double-clicks the object.
Once the editing is finished you should set designMode to 'no' - then you can save the changed document's HTML to a file.
