lfm streams of ancestors are read/applied before the current lfm. VFI - Visual Form Inheritance Short Descriptionįorms can inherit from other forms.

Without the uses section the IDE must in worst case search and read every reachable lfm file on disk. But the IDE must somehow find the referenced form. Technically there is no connection between the uses section and the form streaming, because form streaming uses global variables. Allow to connect to forms, that are used in the uses section.Reopen/Revert a form - all connected forms are now closed.Opening a unit now checks if designer is already created.When referenced component is deleted, the using units must be set modified.When referenced component is renamed, the using units must be set modified.When all referring forms are closed/hidden, the hidden component will be automatically freed.When target form is closed, then only the designer is closed.When reference form is opened, then target forms are opened too.But the designer must be flagged 'modified', because the lfm has changed.

When a component is renamed the property does not need to be updated, because the form is open and use the pointer not the name.Maybe eventually a check could be added, if this is implemented properly and force a nil on error. When component is deleted, the property must be set to nil - This is not the job of the IDE, but should be achieved by the normal TComponent FreeNotification feature.TPersistentPropertyEditor.SetValue - search the component via the given path.TPersistentPropertyEditor.GetValue - Show component path.Check for class compatibility and if the target form is listed in the CreateForm statements of the lpr file and if the target unit does not belong to a package that will conflict if used. TPersistentPropertyEditor.GetValues - List all possible values.Manual referencing via source code works.

A common example is to use the TDataSource on a DataModule for the DataSource property of a db control.ĭesigner forms can only reference each other if they have a CreateForm statement in the lpr file (Project Options / Forms). This feature allows to use components of other designer forms. Multi form properties / using DataModules from other forms in the designer Short Description 2 Translations, i18n, lrt files, po files.1 Multi form properties / using DataModules from other forms in the designer.
