I am using the oiexample.lpi project that is included in the examples, and I realize that properties which are components, ie components on the form, such datasources and controls can't be edited.
So when I add a component which requires a DataSource property to be set, such as TEdit, and I select the DataSource property, none of the datasources I've added to the form appear.
When I add a more complex object such as a TDBGrid, I can edit the Columns property because DBPropEdits has been added it contains a
RegisterPropertyEditor(TypeInfo(TDBGridColumns), nil, '', TDBGridColumnsPropertyEditor);
After searching through the code I can't find a RegisterPropertyEditor(TypeInfo(TDataSource),xxx,TDataSourceProperyEditor)
In short it looks like I am missing a RegisterPropertyEditor command for components or subsets for Components.
I suspect that one of the files in ideintf has a generic RegisterPropertyEditor that needs to be included in the project and for each such property I must make a call to it using the component type as a parameter.
Any idea what that procedure may be?
