It looks like the issue may be coming from your directfb implementation ... on which platform does it run ? Anyway, just to be sure, you can try the following: First, try to launch your program with the following option: --dfb:cursor, and see if the cursor appears (this is equivalent to having the cursor directive specified in directfb configuration file, eg directfbrc). If it works, you may consider creating a directfbrc file under /etc, or a .directfbrc file in your home dir or in the working dir. If it doesn't, try the other layer cursor functions (EnableCursor and SetCursorOpacity), ... David

I implemented your suggestions and now I don't get any errors. However, the cursor is not being displayed. I get mouse move events and I can see that as the mouse moves over various components they get highlighted, but the mouse cursor itself is not visible. I'm using directfb 1.0 and I don't have a directfbrc file. Any suggestions on how I should proceed? thanks a lot Dhoti david.corvoys...@orange-ftgroup.com wrote: Hi I don't know about your error, since it seems to occur on a simple CreateSurface operation, but anyway, this is how you shoud do to change the cursor image (here with a cursor image from a file). I think that you need in particular to request at least administrative privileges on the layer before modifying the cursor (and go back to shared once you're done). <snip> IDirectFB *dfb = NULL; // Create main directfb administrative interface DFBCHECK(DirectFBCreate(&dfb)); if (!dfb) return -1; // Get a handle on the primary layer IDirectFBDisplayLayer* layer = NULL; DFBCHECK(dfb->GetDisplayLayer(dfb, DLID_PRIMARY, &layer)); IDirectFBSurface* cursor; DFBSurfaceDescription idsc; IDirectFBImageProvider* iprov = NULL; /* Acquire cursor image */ if ((dfb->CreateImageProvider(dfb, "/path/to/my/cursor/cursor.png", &iprov)) == DFB_OK){ /* Create the cursor surface */ DFBCHECK(iprov->GetSurfaceDescription(iprov, &idsc)); idsc.flags = DFBSurfaceDescriptionFlags(DSDESC_WIDTH | DSDESC_HEIGHT |DSDESC_CAPS); idsc.caps = DFBSurfaceCapabilities(DSCAPS_SYSTEMONLY); if(dfb->CreateSurface(dfb, &idsc, &cursor) == DFB_OK){ /* Render the cursor onto the image surface */ DFBCHECK(iprov->RenderTo(iprov, cursor, NULL)); } iprov->Release(iprov); /* Set cursor shape */ DFBCHECK(layer->SetCooperativeLevel(layer, DLSCL_ADMINISTRATIVE)); DFBCHECK(layer->SetCursorShape(layer,cursor, 0,0)); /* 0,0 -> cursor hotpoint is at 0,0 */ DFBCHECK(layer->SetCooperativeLevel(layer, DLSCL_SHARED)); } </snip> Regards David PS: please also verify that the no-cursor directive is not specified in your directfbrc file. -----Message d'origine----- De : directfb-dev-boun...@directfb.org [mailto:directfb-dev-boun...@directfb.org] De la part de Dhoti Walla Envoyé : dimanche 13 mars 2011 16:14 À : Maik Greubel Cc : directfb-dev@directfb.org Objet : Re: [directfb-dev] question on mouse cursor Maik, thanks for your response. I should have mentioned that I'm running this on a Set Top Box and basic GUI and event handling work fine. Only the mouse does not work.
