Methods

AllowScreenSaver(bool, string?)

Sets whether or not a screensaver is allowed to draw on top of the window. For games with long cutscenes it would be appropriate to set this to false, while tools that act like normal applications should set this to true. By default this setting is untouched.

Declaration
public void AllowScreenSaver(bool allow, string? disableReason)
Parameters
Type Name Description
bool allow

Whether to allow screensavers to appear while the application is running.
string disableReason

A reason for why the screen saver is disabled. This string should both contain the reason why the screen saver is disabed as well as the name of the application so the user knows which application is preventing the screen saver from running. If null is sent the following default message will be sent:

$"{ApplicationName} is is preventing screen saver."
