واجهة برمجة تطبيق Healthy_Food (الجزء العلوي)
A screenshot of a blocks-based programming environment (similar to App Inventor) for an application named 'Healthy_Food'. It displays the 'Blocks' palette on the left (labeled 4) and the 'Viewer' area on the right (labeled 5) where programming logic is assembled. The numbers 4 and 5 are internal labels for areas within the diagram, not external question numbers.
واجهة برمجة تطبيق Healthy_Food (الجزء السفلي)
A continuation of the blocks-based programming environment for the 'Healthy_Food' app. It shows the 'Blocks' palette on the left (labeled 6) with the 'Foods' component expanded, and the 'Viewer' area on the right (labeled 7 and 8) with more blocks, alongside the 'Properties' panel (labeled 9). The numbers 6, 7, 8, and 9 are internal labels for areas within the diagram, not external question numbers.
كتلة حدث AfterPicking لمنتقي القائمة
A highlighted yellow programming block illustrating the 'AfterPicking' event for a ListPicker component named 'Foods'. This block is directly explained by the Arabic text above it.

**DIAGRAM**: واجهة برمجة تطبيق Healthy_Food (الجزء العلوي)
Description: A screenshot of a blocks-based programming environment (similar to App Inventor) for an application named 'Healthy_Food'. It displays the 'Blocks' palette on the left (labeled 4) and the 'Viewer' area on the right (labeled 5) where programming logic is assembled. The numbers 4 and 5 are internal labels for areas within the diagram, not external question numbers.
Context: This diagram illustrates the initial setup of an App Inventor project, including global variable declarations, list initialization for a ListPicker component, and basic event handling for screen navigation and ListPicker population.

Description: A continuation of the blocks-based programming environment for the 'Healthy_Food' app. It shows the 'Blocks' palette on the left (labeled 6) with the 'Foods' component expanded, and the 'Viewer' area on the right (labeled 7 and 8) with more blocks, alongside the 'Properties' panel (labeled 9). The numbers 6, 7, 8, and 9 are internal labels for areas within the diagram, not external question numbers.
Context: This diagram further elaborates on component property manipulation and event handling in App Inventor, specifically demonstrating how to interact with a ListPicker component and its associated properties and events.
**DIAGRAM**: كتلة حدث AfterPicking لمنتقي القائمة
Description: A highlighted yellow programming block illustrating the 'AfterPicking' event for a ListPicker component named 'Foods'. This block is directly explained by the Arabic text above it.
Context: This block is a specific example of how to capture and utilize the user's selection from a ListPicker component, which is a common UI interaction pattern in mobile app development. The accompanying text explains its function.
