error : 'DoAction' is not a member of 'Upp:TopWindow'
Surely, I should not use WithMydialogLayout<TopWindow>, but I don't understand what to use instead ? Is there some simple example showing how to do that ?
I think that the difficulty for me is that I don't understand well what the code
WithMydialogLayout<TopWindow>
is doing... I suppose that we ask to construct a dialog box from the Layout, with 'TopWindow' as base class ? But what are the possible base classes for dialog boxes ? I was unable to find some document describing the base classses and their hierarchy (as I suggested in this post, some more links between the various pages of documentation should help everybody a lot, especially beginners )
