jevois::ImGuiBackendMALI Class Reference

#include <jevois/GPU/ImGuiBackendMALI.H>

BackendMALI for ImGui on JeVois-Pro.

This abstract base class provides an interface used by VideoDisplayGUI. Derived implementations are available for SDL2 and Mali framebuffer + evdev.

JeVois Pro hardware reports the following:

Member Function Documentation

◆ addDevice()

void jevois::ImGuiBackendMALI::addDevice ( size_t  num,
int  fd 
)
protected

◆ init()

void jevois::ImGuiBackendMALI::init ( unsigned short  w,
unsigned short  h,
bool  fullscreen = false,
float  scale = 1.0f,
bool  conslock = true 
)
virtual

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

The init starts with the given initial window/framebuffer size. If conslock is true, we lock the console and the framebuffer; set to false when running in gdb for debugging, using gdb –args jevoispro-daemon –conslock=false
