MediaPlayer (C++)
Description
This example demonstrates the use of the TMediaPlayer component, assuming that two buttons, for Open and Stop, are on the form. Note: AutoEnable must be set to False for you to be able to control the buttons manually.
Code
void __fastcall TForm2::btOpenClick(TObject *Sender)
{
TOpenDialog* OpenMediaDialog;
OpenMediaDialog = new TOpenDialog(this);
OpenMediaDialog->Filter = "All Video Files (*.avi)|*.avi";
// Browse for .avi files on your computer
if (OpenMediaDialog->Execute())
{
/* Assign a file to the media player. */
MediaPlayer1->FileName = OpenMediaDialog->FileName;
/* Check if the file exists and is not a directory .*/
if ((FileExists(OpenMediaDialog->FileName)) &&
(!DirectoryExists(OpenMediaDialog->FileName)))
{
/* Open the files. */
MediaPlayer1->Wait = true;
MediaPlayer1->Open();
MediaPlayer1->Play();
/* Override automatic button controlling. */
MediaPlayer1->EnabledButtons =
TButtonSet() <<
TMPBtnType::btPause <<
TMPBtnType::btStop <<
TMPBtnType::btPlay;
/* Enable the Stop button. */
btStop->Enabled = true;
btOpen->Enabled = false;
}
}
delete OpenMediaDialog;
}
void __fastcall TForm2::btStopClick(TObject *Sender)
{
/* Stop and close the media. */
MediaPlayer1->Stop();
MediaPlayer1->Close();
MediaPlayer1->EnabledButtons = TButtonSet();
/* Enable the Open button again. */
btOpen->Enabled = true;
}
__fastcall TForm2::TForm2(TComponent* Owner)
: TForm(Owner)
{
/* Disable all the buttons.*/
MediaPlayer1->AutoEnable = false;
MediaPlayer1->EnabledButtons = TButtonSet();
}
void __fastcall TForm2::MediaPlayer1PostClick(TObject *Sender,
TMPBtnType Button)
{
if (Button == TMPBtnType::btStop)
btStop->Click();
}
