Re: How to enable animation in GTK 2 application ?

[Dov Grobgeld <dov grobgeld gmail com>]

For most animations the function that you need is g_timeout_add() that makes the main loop of gtk/glib call a function of your choice after a certain interval (the animation step). By returning true from this function, the function will be called again after the same interval. Depending on what kind of animation you want to do, you can do several different things in the timeout callback function:

• If your animation is built of a stack of images, then you can request to display the next image.
• If your animation is a set of canvas items on one of the gtk canvases (e.g. goocanvas) then you can request to move the canvas item to a new position.

This might be enough for your needs, though in your question it sounds like e.g. you want to do user interface animations, which is a totally different story.

Dear Friends,

Im working on a game application which needs a funky look and few animations in it. Im new to GTK and learning it from online tutorial posted on gtk.org site. There they haven't mentioned anything about animating windows or frames or even special effects just like the one in gnome desktop project.

How do i give special effects and animations to this game without requiring more processing speeds n huge memories?
