Hi Guys
I would like a help to solve a problem in my application.
I have a CVM (Java Virtual Machine) portable to a Digital TV platform
that has a AWT (Abstract Windon Toolkit) implementation using DirectFB
API. I dont have access to the AWT implementation.
This implementation has a bug that I hope it is possible to solve
using a DirectFB API .
Specifically I want to clean the screen using a JNI called to the DirectFB
Api.
I already done the API;
In Java Side I have the following method.
public native void clearScreen();
In JNI Side;
static IDirectFB *dfb = NULL;
static IDirectFBSurface *primary = NULL;
DFBSurfaceDescription dsc;
DirectFBInit (NULL, NULL));
DirectFBCreate (&dfb);
dsc.flags = DSDESC_CAPS;
dsc.caps = DSCAPS_SYSTEMONLY;
You try to create the surface in the SYSTEM memory, not VIDEO !
Change the line to 'dsc.caps = DSCAPS_PRIMARY'.
dfb->CreateSurface( dfb, &dsc, &primary );
primary->Clear(primary,100,100,100,100);
primary->Release (primary);
dfb->Release (dfb);
But nothing happened
Could you help me?
Regards
Alvaro
