Files

File in Delphi	File in C++	Contains
PlayAudioFile.dproj	PlayAudioFile.cbproj	The project itself.
PlayAudioFile.fmx	PlayAudioFile.fmx	The main form where the components are located.
PlayAudioFile.pas	PlayAudioPCH.h, PlayAudio.cpp	Used to define and implement the sample.
soundsample.mp3	soundsample.mp3	The audio file.

Classes

TAudioPlayBackForm is the main form that represents the main window of the sample. It contains the following components:

• A TMediaPlayer object.
• A ToolBar object with:
  • Two TSpeedButton objects.
  • A TLabel object.

Implementation

• The sample uses GetDocumentsPath to obtain the path to the directory where user documents are stored.
• The sample uses TMediaPlayer component for easy access to media files.
• The sample uses TSpeedButton to implement two push-buttons for playing and stoping the reproduction of the audio file.

When you run the aplication, the sample shows a ToolBar with two TSpeedButton objects with the stylelookup set to stoptoolbuttonbordered and playtoolbuttonbordered. When you click the play button, the sample uses GetDocumentsPath to obtain the media file, and TMediaPlayer.Play to reproduce it. When you click on the stop button, the sample uses TMediaPlayer.Stop to stop the reproduction of the media file.
