THtmlViewer component
property OnHotSpotCovered: THotSpotEvent;
The OnSpotCovered event occurs when the mouse is moved over or away from an hypertext link. This event may be used to display the destination URL of a hypertext link to allow the user to decide if it should be selected.
The following code may be used to provide a status line display of the hypertext link at the mouse position:
Viewer.OnHotSpotCovered := HotSpotChange;
...
procedure TForm1.HotSpotChange(Sender: TObject; const URL: string);
begin
Panel1.Caption := URL;
end;
