| 36 <h1>Full-screen and Mouse-lock Example</h1> |
| 37 <ul> |
| 38 <li>There are two different kinds of fullscreen mode: "tab fullscreen" and |
| 39 "browser fullscreen". |
| 40 <ul> |
| 41 <li>Tab fullscreen refers to when a tab enters fullscreen mode via the |
| 42 JS or Pepper fullscreen API.</li> |
| 43 <li>Browser fullscreen refers to the user putting the browser itself |
| 44 into fullscreen mode from the UI (e.g., pressing F11).</li> |
| 45 </ul> |
| 46 <span style="font-weight:bold"> |
| 47 NOTE: Mouse lock is only allowed in "tab fullscreen" mode. |
| 48 </span> |
| 49 </li> |
| 50 <li>Lock mouse: |
| 51 <ul> |
| 52 <li>left click in the grey box; or</li> |
| 53 <li>right click in the box to ensure that it is focused and |
| 54 then press Enter key. (You could verify that the tooltip window is |
| 55 dismissed properly by this second approach.)</li> |
| 56 </ul> |
| 57 </li> |
| 58 <li>Unlock mouse voluntarily (i.e., NaCl module unlocks mouse): |
| 59 <ul> |
| 60 <li>press Enter.</li> |
| 61 </ul> |
| 62 </li> |
| 63 <li>Unlock mouse involuntarily (i.e. Chrome unlock mouse): |
| 64 <ul> |
| 65 <li>lose focus; or</li> |
| 66 <li>press Esc key; or</li> |
| 67 <li>exit from the "tab fullscreen" mode.</li> |
| 68 </ul> |
| 69 </li> |
| 70 </ul> |
| 71 <p>Clicking the mouse inside the grey square takes the NaCl module to/from |
| 72 combined fullscreen and mouselock mode.</p> |
| 73 <p>While in fullscreen, pressing Enter will exit/enter mouse lock mode.</p> |
| 74 <!-- Load the published .nexe. This includes the 'src' attribute which |
| 75 shows how to load multi-architecture modules. Each entry in the "nexes" |
| 76 object in the .nmf manifest file is a key-value pair: the key is the runtime |
| 77 ('x86-32', 'x86-64', etc.); the value is a URL for the desired NaCl module. |
| 78 To load the debug versions of your .nexes, set the 'src' attribute to the |
| 79 _dbg.nmf version of the manifest file. |
| 80 |
| 81 Note: The <EMBED> element is wrapped inside a <DIV>, which has both a 'load' |
| 82 and a 'message' event listener attached. This wrapping method is used |
| 83 instead of attaching the event listeners directly to the <EMBED> element to |
| 84 ensure that the listeners are active before the NaCl module 'load' event |
| 85 fires. This also allows you to use PPB_Messaging.PostMessage() (in C) or |
| 86 pp::Instance.PostMessage() (in C++) from within the initialization code in |
| 87 your NaCl module. |
