This is not the case. Even with Qt Components, there are several components that are specific to either Symbian or Meego-Harmattan. The workload is reduced, but unless your application is 'hello world', it's not as simple as clicking a button. Some examples: 1. PageStackWindow component not available in Symbian. 2. Label component not available in Symbian 3. InfoBanner component has different methods in Symbian than the Meego-Harmattan equivalent. 4. Sheet component not available in Symbian. 5. Dialog component layout/behaviour is different in Symbian than in Meego-Harmattan. 6. MultiSelectionDialog component not available in Symbian. 7. ListItem component not available in Meego-Harmattan. 8. ListItemText component not available in Meego-Harmattan. 9. ToolIcon component not available in Symbian. 10. Available icons for ToolButton/ToolIcon differ between the two platforms. 11. TabBar component not available in Meego-Harmattan. 12. SelectionListItem component not available in Meego-Harmattan.
