The GmbSprite widget is the simple sprite manipulation framework that will be used in the next version of "Gnome Memory Blocks" (http://gnome-memblocks.sourceforge.net). Main goal was to write something intermediate between plain GdkDrawingArea widget and the intelligent GnomeCanvas. Actually, mostly all of event handling code was "stolen" from GnomeCanvas. (and slightly uglified :)) At present moment gmb-sprite consists of the following GTK+ widgets/objects: * GtkWidget +---GmbSpriteArea (see gmb-sprite/gmb-sprite-area.h) Oversimplified "flicker guard" & container for GmbSprites. As a container it is similar to the GtkFixed, i.e. you have to specify sprites positions explicitly. As a "flicker guard" it is similar to the GnomeCanvas in not-antialiased mode; due to simplisity of (expected) using there is no objects similar to GnomeCanvasItemGroup and all GmbSprite's has rectangular shapes. You have to specify the widget size manually using gtk_widget_set_usize() or to derive a subclass that implements `size_request' GtkWidget's method. * GtkObject +---GmbSprite That is the abstract class for sprites. Has some usefull methods like `move', `show'/`hide' and `lower'/'raise'. It also emits `event' signal for mouse events. * GtkObject +---GmbSprite +---GmbSpritePixmap Just pixmap & mask. * GtkObject +---GmbSprite +---GmbSpritePixbuf It uses standard GdkPixbuf features to render itself with given alpha value. It can also do `smooth' transformation of currently displayed GdkPixbuf area to anouther one. * GtkObject +---GmbAnimation That is the animation container which we need only because GdkPixbufAnimation structure is opaque. * GtkObject +---GmbSprite +---GmbSpriteAnimator This provide standard animation routines such as playing animation in normal and reversed directions, in different loop modes together with emiting "playback finished" signal. For demo program see `tests/test-animator'. is finished. See `test-animator' in the tests directory. Vova Babin, <vb@dwuj.ichf.edu.pl>.
