How do I make screen saver applicaion in Delphi
To create a screen saver application in Delphi, you can use the TScreenSaver component from the Delphi component library. This component allows you to create a screen saver that can be installed and configured on the user’s computer, just like any other screen saver.
Here is an example of how you can use the TScreenSaver component in Delphi to create a screen saver application;
- Install the System package from the Delphi component library.
- In the uses clause of your Delphi unit, add Winapi.Windows and Winapi.Messages.
- Drag a TScreenSaver component from the Delphi component palette onto your form.
- Set the Active property of the TScreenSaver component to True.
- In the OnCloseQuery event of the form, add the following code to prevent the user from closing the screen saver window
|
1 2 3 4 |
procedure TForm1.FormCloseQuery(Sender TObject; var CanClose Boolean); begin CanClose = False; end; |
In the OnCreate event of the form, add the following code to initialize the screen saver and set up a timer to update the screen saver animation
|
1 2 3 4 5 6 7 |
procedure TForm1.FormCreate(Sender TObject); begin Initialize the screen saver ScreenSaver1.Initialize; Set up a timer to update the screen saver animation SetTimer(Handle, 1, 1000, nil); end; |
In the OnTimer event of the form, add the following code to update the screen saver animation
|
1 2 3 4 |
procedure TForm1.FormTimer(Sender TObject); begin Update the screen saver animation here end; |
This is just a basic example of how you can use the TScreenSaver component to create a screen saver application in Delphi. You can customize the behavior of the screen saver by using the other properties and methods of the TScreenSaver class, such as handling user input and displaying a preview of the screen saver in the Windows control panel. For more information, please refer to the Delphi documentation and the TScreenSaver class reference.
