Member Function Documentation

◆ init()

void jevois::VideoDisplayBackendMALI::init ( unsigned short  w,
unsigned short  h,
bool  fullscreen = false 
)
overridevirtual

Initialize the underlying engine that will process events, create windows, etc.

The init starts with the given initial framebuffer size. Note that on MALI, size and fullscreen parameters are ignored and we always run full-screen at the native resolution of the framebuffer.

Implements jevois::VideoDisplayBackend.

◆ pollEvents()

bool jevois::VideoDisplayBackendMALI::pollEvents ( bool &  shouldclose)
overridevirtual

Poll events such as mouse movements, buttons, keyboard, joystick, and pass to VideoDisplay.

Returns true if some events were received, which can be used to turn on mouse pointer and GUI. On MALI, there is no support for events at this level, and hence no support for a test to close.

Implements jevois::VideoDisplayBackend.

Reimplemented in jevois::ImGuiBackendMALI.
