javascript - Indicator for a 360 image rotation -


i have simple 360 image rotator cycles through series of images create effect of rotating object. want add indicator shows users can rotate object fades out after fist image has been past. added function end of 360.js

(function(){      if( $('#first').css('visibility','hidden')) {     $('#rotate').fadeout(); }  else {     $('#rotate').fadein(); }       });

theres no error in script, it's not checking see if image visible or not. tried binding mousedown , mousemove events called in 360.js no luck. 1 have ideas on how resolve this?

heres fiddle

there 1 major problem beside listed on comments.

you're setting currentimage 1, instead of 0, , indexing 0 based. image want never again visible, fading in never happens.

i check whether has class 'notseen', though checking hidden should have been good.

here's latest fix, , should see works: http://jsfiddle.net/y7wma/6/

and here significant snippets:

.bind('mousemove touchmove', function (e) {     fadeinout();     // ...         if (math.abs(currpos - pagex) >= widthstep) {             if (currpos - pagex >= widthstep) {                 currimg++;                 if (currimg > imagetotal) {                     currimg = 0;                 }             } else {                 currimg--;                 if (currimg < 0) {                     currimg = imagetotal;                 }             } // ... function fadeinout() {     if ($('#first').hasclass('notseen')) {         console.log("hidden");         $('#rotate').fadeout();     } else {        console.log("visible");         $('#rotate').fadein();     }  };

c++ - Correct method for redrawing a layered window -

i have window created ws_ex_layered window style. drawing onto memory bitmap using gdi+, , using updatelayeredwindow update graphical content of layered window. intend use window main window of application, require redraw frequently. seeing layered windows not receive wm_paint windows message [?] , need come appropriate method re-drawing window. optimisation not essential , it's nice have cake , eat too. therefore, in search of "correct" method use. here thoughts far: i guess it's idea render onto off-screen bitmap before bitblt ing or similar. 60 frames rendered per second should (more than?) enough (but how compare other applications' frame rates?). possible solutions: use settimer send wm_timer message on regular basis. useful because through specifying time-out value, can achieve desired frames per second, without requirement measure duration "frame" takes rendered. would cause input or other lags due frequency , speed of m...
