I have a component (TComponent descendant) which is for use on TDataModule and must look like TLabel (not as a rectangle with icon). I also did custom Form designer (for a derived datamodule). Is it even possible to make "TLabel" representation of a component in TDataModule? Is there any sample, hotw to create designt-time representation of a a component?

Not really, since DataModules don't have visual components. It might help to know exactly why you want to do this. -- Dave Nottage [TeamB] Back to top Frenk Guest Posted: Thu Jul 28, 2005 10:06 am    Post subject: Re: TComponent with TLabel "designtime" on TDataModule situation: TMyComponent = class(TComponent) end ..... After this component is put into DataModule (design time), instead of standard visual representation of TComponent (a rectangle with an icon in a center) "Label" should be painted (as a visual representanion of the TMyComponent object) on designtime surface.

I don't think that's going to be possible without a deal of messing around with how a DataModule itself behaves. I personally don't see anything wrong with showing a form when double-clicking the component (or right-clicking and having a menu item available for it). That kind of thing works OK for the fields editor for a TDataset component, and the form it shows is not modal. -- Dave Nottage [TeamB] Back to top Frenk Guest Posted: Thu Jul 28, 2005 2:06 pm    Post subject: Re: TComponent with TLabel "designtime" on TDataModule I already implemented CustomDesigner for form (datamodule descendant). The question is, how to register "label" representation to TComponent descendant (like TLabel design-time is bound to TLabel runtime) in design time. CustomDesigner has ComponentContainer TScroolBox, so it is possible to use TLabel as design time representation ("FormDesigner" have the same implementation)? Is it possible to get some docs or examples of implementing CustomDesigner?

Best Regards sergio sette Back to top Frenk Guest Posted: Thu Jul 28, 2005 2:44 pm    Post subject: Re: TComponent with TLabel "designtime" on TDataModule Component editor execute method is fired when dblclick on component occours. So to late. Selection also has no method "Paint designtime representatnion". Will ask another way (don't ask why, the idea is to describe a problem). What to do that Tcomponent descendant TMyComponent on TForm will show in designtime as TLabel?

Descend it from TCustomLabel, presumably. As I alluded to in my previous replies, DataModules don't "accept" "visual" components. Again, I really can't see what the problem is with creating a component designer that is invoked by the context menu or by double-clicking it. -- Dave Nottage [TeamB] Back to top Frenk Guest Posted: Thu Jul 28, 2005 7:01 pm    Post subject: Re: TComponent with TLabel "designtime" on TDataModule Why not? Because you have problems with thread-safety if you create TForm descendant in ISAPI/COM+ Free model. So everything shoud be descend form TDatamodule, but also visual designer is needed. Isn't here any borland developer or somebody that did the same thing or know how to do that (maybe guys from intraweb or EWF?)
