[E-devel] Evas_Object MOUSE_DOWN blocks MOUSE_IN/OUT ?
I've got a question regarding Evas. I am coding a Winamp3/5 WAL skin
loader, or at least the UI part of it since it will also require of
having a MAKI bytecode interpreter, but that's another topic of course.
Basically i'm implementing widgets using custom pixmaps, and the problem
that i have is:
I'm connecting handlers for all events MOUSE_IN, MOUSE_OUT, MOUSE_DOWN
and MOUSE_UP for an Evas_Object.
What i need to implement for this particular widget (button) is of
course that when the mouse button is kept pressed but the pointer moves
outside of the widget's area, the image is restored to the unpressed one
(as it's the case with basically every GUI toolkit there is).
Now the situation is that after MOUSE_DOWN was called and the mouse
button is kept pressed by the user, the MOUSE_IN and MOUSE_OUT events
are never being called, and i have no idea how to make the widget
receive the appropriate information so it can do the redraw.
Any hints on how to accomplish that, or is this a bug in Evas?

THEN it gets a mouse out just after the mouse up. basically i've left it up to the programmer to deal with this in the mouse motion events. you can check each motion event if the mouse is within, or outside the bounds o the object and then know if its in our out yourself. basically the mouse is still VIRTUALLY in the object (not physically) - so until it is both virtually and physically outside.. u wont get an out. :) :) yes that makes much more sense actually :) but it is not obvious to me how i can retrieve the particular event structure inside the callback... i checked the docs and include files, also the evas source but i can't find it. how do i need to do that? --- This SF.Net email is sponsored by: YOU BE THE JUDGE.
