Doug B | Has anyone successfully created an EWB external interface to a third-party set of JavaScript components?
Among other things, I'm looking for a menu component to use in my application. I have some deadlines I need to meet that require some UI elements like menus and graphs. Thanks, Doug |

It is certainly possible to use third party javascript, but you'd probably not want to use deep UI stuff as they will depend on other framework operations, and EWB may conflict. But as I've posted elsewhere, making a menu from panels is not hard - I was surprised at how flexible and good looking you can make "assembled" components. -- Matthew Jones |

Doug B | Thanks, Matthew.
I found the demo and modified it slightly for EWB2, however what I'm currently doing requires converting relative coordinates to absolute coordinates due to an additional level of nesting for my main menu. Is there something like Delphi's ScreenToClient() and ClientToScreen() functions to convert back and forth from relative to 'absolute' screen coordinates? >> But as I've posted elsewhere, making a menu from panels is not hard - I was surprised at >> how flexible and good looking you can make "assembled" components. To be honest, as flexible it is, my goal is to get my project done, not hack together my own simulated menu. I'm not trying to be unreasonably critical, as I do appreciate all the work that has obviously gone into EWB2, but I would have expected a menu to be one of the most fundamental components included. Hopefully one will show up in the near future. Doug |

Not sure if it is quite what you want, but I used this to modify mouse coordinates. procedure TfrmMine.ImageMouseMove(Sender: TObject; ShiftKey, CtrlKey, AltKey: Boolean; X,Y: Integer); var xObject : TControl; xParent : TControl; begin if Sender is TControl then begin xObject := TControl(Sender); while xObject <> self do begin xParent := xObject.Parent; X := X + xObject.Left; Y := Y + xObject.Top; if (xObject is TPanel) then begin Y := Y - TPanel(xObject).ScrollTop; end; xObject := xParent; end; end; -- Matthew Jones |

Doug B | I was planning on doing something similar, so thanks for posting the code.

Perhaps in the future it would be helpful to have some sort of publicly visible (registered users only) voting system for 'wish list' components? Although I'm sure you have a pretty good idea what those are based on customer requests... Doug |

Doug B | Thanks Tim, that's exactly what I needed.
