OK.
So - does it means that
super_interface->SetCooperativeLevel( super_interface,
DFSCL_FULLSCREEN );
also create surface for primary layer, and Flip() it?
Program works ok if i write (1a).
Does it means that I have to always create _PRIMARY surface, and
Flip() it before input handle (everything else)?
And if I do not want use this surface should I release it just after
Flip(), or at the end of program?
Because if I write this withought X-2:
DirectFBInit( &argc, &argv ); + error check
DirectFBCreate( &super_interface ); + error check
super_interface->SetCooperativeLevel( super_interface, DFSCL_NORMAL );
+ error check
super_interface->SetVideoMode( super_interface, 720, 720, 32 ); +
error check
/*(X-1)*/ IDirectFBSurface * primary_surface = NULL;
DFBSurfaceDescription primary_surface_description;
primary_surface_description.flags = DSDESC_CAPS;
primary_surface_description.caps = DSCAPS_PRIMARY |
DSCAPS_FLIPPING;
super_interface->CreateSurface( super_interface,
&primary_surface_description, &primary_surface ); + error check
primary_surface->Flip( primary_surface, NULL, 0 ); + error check
/* (X-2)*/ IDirectFBDisplayLayer * osd_layer = NULL;
super_interface->GetDisplayLayer(super_interface, 0,
&osd_layer); + error check
osd_layer->SetCooperativeLevel( osd_layer, DLSCL_EXCLUSIVE))
!= DFB_OK ); + error check
IDirectFBSurface * osd_surface = NULL;
osd_layer->GetSurface ( osd_layer, &osd_surface ); + error check
/* (X-3) */ draw something - Yes I see it :-)
osd_surface->Flip( osd_surface, NULL, 0 ); + error check
/*(X-4)*/ DFBEvent user_input_event;
IDirectFBEventBuffer * user_input_event_buffer;
super_interface->CreateInputEventBuffer(super_interface,
DICAPS_KEYS, DFB_FALSE, &user_input_event_buffer); + error check
user_input_event_buffer->WaitForEvent(user_input_event_buffer); +
error check
user_input_event_buffer->GetEvent( user_input_event_buffer,
&user_input_event ); + error check
ten program still hang up in X-4 WaitForEvent(),
and I still need to write X-2 to program work ok.
