I have a project where I try to share form files between Delphi and Lazarus. This actually works well excep with GroupBox there "top" values is caluculated against two different "tops". This menas that in Lazarus the controls are moved about 20-30 pixels too far down the TGroupBox.
Anyhow, assuming I design in Delphi, and I make a descendant TGroupBox. IO could Add a property called "fixiffromdelphi" (or something like that) and then add some code which ensures the child controls get placed correctly.
Ideally, this should happen under streamning, but I am not sure how to go about it. Is there anyway the parent (GroupBox) can access the subcontrols while the form streams in the dfm/lfm? And through that override e.g. top value?
