Overview of this book

Delphi is a strongly typed, event-driven programming language with a rich ecosystem of frameworks and support tools. It comes with an extensive set of web and database libraries for rapid application development on desktop, mobile, and internet-enabled devices. This book will help you keep up with the latest IDE features and provide a sound foundation of project management and recent language enhancements to take your productivity to the next level. You’ll discover how simple it is to support popular mobile device features such as sensors, cameras, and GPS. The book will help you feel comfortable working with FireMonkey and styles and incorporating 3D user interfaces in new ways. As you advance, you’ll be able to build cross-platform solutions that not only look native but also take advantage of a wide array of device capabilities. You’ll also learn how to use embedded databases, such as SQLite and InterBase ToGo, synchronizing them with your own custom backend servers or modules using the powerful RAD Server engine. The book concludes by sharing tips for testing and deploying your end-to-end application suite for a smooth user experience. By the end of this book, you’ll be able to deliver modern enterprise applications using Delphi confidently.

Sharing your pictures

Almost every mobile app has some way of sharing pictures and text on social media services, through file-sharing sites and as attachments in text messages or emails. It's been made super-simple to do so in your Delphi app by simply using another one of the standard actions similar to taking a photo. From the action list in your app, add a new standard action and select TShowShareSheetAction in the Media Library section. Assign it to a new button in the toolbar at the bottom of tabParkEdit.

We'll hook into just one of the events, OnBeforeExecute, which lets us set up what we're going to share, as follows:

procedure TfrmMyParksMain.ShowShareSheetActionBeforeExecute(Sender: TObject);
begin
  ShowShareSheetAction.Bitmap := imgParkPic.Bitmap;
  ShowShareSheetAction.TextMessage := Format('%s (%0.5f,     %0.5f)',
