Member Enumeration Documentation

EForceMaxTouchpadSensitivityAsyncBehavior

enum class FWindowsApplication::EForceMaxTouchpadSensitivityAsyncBehavior : uint8

strong

On Windows 10 22H2 and later where we can set the touchpad sensitivity system wide setting force it to most sensitive so that touch swipes are not ignored while keyboard keys are being depressed. In Windows 11 24H2 a new api was added which can change this setting only for this app.

We reccomend that this feature be exposed as a user setting which is enabled by default and hidden/disabled if SupportsForceMaxTouchpadSensitivity() returns false and that the CVar be used to activate it rather than directly calling ApplyForceMaxTouchpadSensitivity/RemoveForceMaxTouchpadSensitivity due to the complexity of handling the focus/exit/crash cases with the SetTouchpadParameters api.

See WindowsApplication.cpp namespace UE::WindowsApplication::TouchpadSensitivity for more information about this system.

EForceMaxTouchpadSensitivityRestorationValues

enum class FWindowsApplication::EForceMaxTouchpadSensitivityRestorationValues : int32

strong

If we are using the system wide setting it is possible that we could crash and fail to set it back. Call this function to find out if we have a system setting value we would like to restore after a crash. If this information was passed to a separate process (perhaps by writing it to a file) that process might be able to restore the setting after a crash.
