I have four layers.
First of them is:
layer_id: 0
name: FBDev Primary Layer [OSD]
type :(DLTF_GRAPHICS, )
capabilities :(DLCAPS_SURFACE, DLCAPS_OPACITY, DLCAPS_ALPHACHANNEL,
DLCAPS_SCREEN_LOCATION, DLCAPS_LEVELS, DLCAPS_SCREEN_POSITION,
DLCAPS_SCREEN_SIZE, )
level: 0
regions: 0
sources: 0
clip_regions: 0
My code:
...
/** Setings layers. */
IDirectFBDisplayLayer * osd_layer = NULL;
if( (dfberr = super_interface->GetDisplayLayer(super_interface, 0,
&osd_layer)) != DFB_OK ) { DirectFBErrorFatal( "GetDisplayLayer()",
dfberr); }
int l;
if( (dfberr = osd_layer->GetLevel( osd_layer, &l )) != DFB_OK ) {
DirectFBErrorFatal( "GetLevel()", dfberr); }
printf("%d\n", l );
if( (dfberr = osd_layer->SetLevel( osd_layer, 4 )) != DFB_OK ) {
DirectFBErrorFatal( "SetLevel()", dfberr); }
...
compilation goes ok, and in the last line got message while program running:
(#) DirectFBError [SetLevel()]: Access denied!
This layer has capability: DLCAPS_LEVELS, so what is wrong ?
