Overview of this book

FireMonkey (FMX) is a cross-platform application framework that allows developers to create exciting user interfaces and deliver applications on multiple operating systems (OS). This book will help you learn visual programming with Delphi and FMX. Starting with an overview of the FMX framework, including a general discussion of the underlying philosophy and approach, you’ll then move on to the fundamentals and architectural details of FMX. You’ll also cover a significant comparison between Delphi and the Visual Component Library (VCL). Next, you’ll focus on the main FMX components, data access/data binding, and style concepts, in addition to understanding how to deliver visually responsive UIs. To address modern application development, the book takes you through topics such as animations and effects, and provides you with a general introduction to parallel programming, specifically targeting UI-related aspects, including application responsiveness. Later, you’ll explore the most important cross-platform services in the FMX framework, which are essential for delivering your application on multiple platforms while retaining the single codebase approach. Finally, you’ll learn about FMX’s built-in 3D functionalities. By the end of this book, you’ll be familiar with the FMX framework and be able to build effective cross-platform apps.

Defining the stand(s)

Our MainForm hosts the TFrameStand component and, through it, handles the management of the views (including the creation, destruction, and showing/hiding them). As previously said, a TStyleBook component has been added to the form as well, to host stand definitions (note the FrameStand1.StandBook property references the StandsBook component).

The actual code that the form uses to build the FrameStands is as follows:

procedure TMainForm.UpdateViewToState;
begin
case MainData.AppState of
Home:
begin
FrameStand1.CloseAllExcept(THomeFrame);
FrameStand1
.GetFrameInfo<THomeFrame>
.Show;
end;
Orders:
begin
FrameStand1.CloseAll(TOrderDetailsFrame);
FrameStand1
.GetFrameInfo<TOrdersFrame>(True, nil, 'fader')
.Show;
end;
OrderDetail:
begin
FrameStand1
.GetFrameInfo<TOrderDetailsFrame>(True, nil, 'slider')
