Detailed Description

Main entry point and handler for nCine applications.

Member Function Documentation

◆ autoSuspension()

bool ncine::Application::autoSuspension ( ) const

inline

Returns the value of the auto-suspension flag.

If true the application will be suspended when it loses focus

◆ frameTime()

float ncine::Application::frameTime ( ) const

Returns the time in seconds that last frame took to complete.

Note: Also called delta time. *‍/

◆ isSuspended()

bool ncine::Application::isSuspended ( ) const

inline

Returns the value of the suspension flag.

If true the application is suspended, it will neither update nor receive events

◆ resizeScreenViewport()

bool ncine::Application::resizeScreenViewport	(	int	width,
		int	height
	)

protected

Resizes the screen viewport, if it exists.

Note: It will also call the onResizeWindow() callback if the size has really changed

◆ updateScalingFactor()

bool ncine::Application::updateScalingFactor ( )

protected

Checks if the window scaling factor has changed this frame.

Note: It will also call the onChangeScalingFactor() callback if the factor has really changed
