i create game marmalade, don't know how make "levels" in it. mean levels, on android screens, or activitys. for example don't know how make menu, click on button (i can make button, control touch...) , create new screen game level. on android there activitys reason, how can in marmalade? you can use marmalade's iwui api this. used creating ui of game. can either use .ui files (similar xml files in android/xib in ios) or can programmatically too. what need is, create separate ciwuielement* objects can represent complete views in game. these can called main page elements or super parent elements. can assign childs super parents, such buttons, images etc. according button clicks can add or remove these super parents iwuicontroller , change views according that. can add elements without removing previous ones, result in overlay. you might want create separate class separate super parent element. i've created base class ui , subclasses h

when i'm trying change document.documentelement.innerhtml using innerhtml of textarea this: document.documentelement.innerhtml = document.queryselector('#mytextarea').innerhtml the innerhtml of #mytextarea not used actual html change dom, plain text. for example: if innerhtml of #mytextarea <p>a paragraph</p> . then document after loading looks like: <p>a paragraph</p> instead of a paragraph how should value inside #mytextarea used change dom? (ex. appending new elements) use .value contents of textarea without being encoded. document.getelementbyid("documentelement").innerhtml = document.queryselector('#mytextarea').value; <textarea id="mytextarea"> <p>a paragraph</p> </textarea> <div id="documentelement"> </div>

i'd confirm think true. when use windows sendmessage() , deterministic call in execute (will not return until message processed) opposed postmessage() non-deterministic can preempted other message happens in queue @ moment in time (in fact not executed until hits message loop). is fair assessment, or missing something? that true in-process calls. cross-process sendmessage works similar, processing of message doesn't begin until receiver process calls getmessage (or kin). your ui thread has message pump looks like: while (getmessage(&msg)) dispatchmessage(&msg); postmessage causes message put onto message queue. getmessage removes oldest message queue (fifo*). dispatchmessage causes wndproc associated message's target window called message. sendmessage bypasses chain , calls wndproc directly (more or less). a lot of standard window messages result in chain of sendmessage calls sending 1 message sends sends another. chain referred "

i've read http://yuilibrary.com/yui/docs/dd/ , still have no clue how register drag event. i'm using jsplumb.draggable make .w class divs draggable, , wanted call hander when element gets dragged. is following coding valid? jsplumb.draggable(y.all(".w")); y.all(".w").on('drag:drag', function() { alert('do here'); }); thanks, i don't think can listen drag event using jsplumb. yui has drag class 1 fires drag event. you'd create instance of class , enough make node draggable. var dd = new y.dd.drag({ node: '#foo' }); dd.on('drag:drag', function () { // }); but jsplumb creates hidden drag instance , keeps itself. there doesn't seem way retrieve drag instance. recommendation open issue in jsplumb's github asking way this.
