[clutter] Problems with clutter-0.9.7 on OS X
Hi, I have pulled the latest code form Git and compiled (configured using --with-flavour=osx). When I run some of the interactive tests I get these errors, any one have any ideas what is wrong? See terminal output below for examples. Thanks :) $ ./test-interactive test-actors dyld: lazy symbol binding failed: Symbol not found: _CLUTTER_UNITS_FROM_FLOAT Referenced from: /Users/jack/Code/clutter-0.9-git/clutter/.libs/libclutter-osx-0.9.0.dylib Expected in: dynamic lookup dyld: Symbol not found: _CLUTTER_UNITS_FROM_FLOAT Referenced from: /Users/jack/Code/clutter-0.9-git/clutter/.libs/libclutter-osx-0.9.0.dylib Expected in: dynamic lookup Trace/BPT trap ~ $ ./test-interactive test-grab Red box:aquire grab on press, releases it on next button release Blue box: aquire grab on press, destroys the blue box actor on release Yellow box: aquire grab on press, releases grab on next press on yellow box Green box: toggle per actor motion events.

[clutter] Practical advice needed for creating custom actors
Hi Clutterers. :) I want to create a tab-widget with a path consisting of a couple of arcs and four lines. The path will be filled with a gradient and the arcs have to be smooth (anti-aliased). I have managed to draw the widget as I want it with ClutterCairoTexture, but I'm wondering if it's better to do it with COGL. Better as in better hardware accelerated performance and perhaps that it's somehow more native to Clutter (although I'm not sure if there's a difference in that sense). Thanks, Alexander -- To unsubscribe send a mail to clutter+unsubscr...@o-hand.com

Better as in better hardware accelerated performance and perhaps that it's somehow more native to Clutter (although I'm not sure if there's a difference in that sense). there is no difference in terms of nativeness; the performance issue is true, though: we use a non-hw accelerated Cairo surface, so you need to make sure you're not updating the contents of the CairoTexture needlessly -- you should draw on your cairo_t* only when the allocation changes, and possibly only if the allocation size is different than the size of the CairoTexture surface. we plan to add more features to the COGL primitives, including anti-aliasing and gradients, but they are for future development cycles. ciao, Emmanuele. [0] it is possible to set up a linear gradient by changing the color at different vertices, but it won't work as well as the Cairo pattern API. -- Emmanuele Bassi, Senior Engineer| emmanuele.ba...@intel.com Intel Open Source Technology Center | http://oss.intel.com -- To unsubscribe send a mail to clutter+unsubscr...@o-hand.com
