About flex shielding default right-click menu, capture right-click events

 

JScript code

 
  1  . If you are a desktop application
  Monitors the mouseevent. right_click event of an event.
  For example, you can right-click an event to monitor a control.
  A. addeventlistener (mouseevent. right_click, func );
  Other mouse events can also be monitored. For details, see http:  //  Livedocs.adobe.com/flex/3_cn/langref/flash/events/mouseevent.html  
  2 . If it is Web appliction (trouble !)
  The basic idea is:

  1  In Flex, you can use an external interface to register a function as an entry to receive external (HTML) Context events.
  2  To intercept the right-click event in the HTML of the Flex application, call the flex external function, and cancel event broadcast to prevent the event from reaching the flex application.
  3  , In the flex ApplicationProgramListen to the Mouseover event and record the object where the current mouse is located
  4  When the portal function receives the right-click event sent by HTML, it simulates the generation of a right-click event (buttondown  =   False  And send it to the current object.
 5  In the mousedown processing function of the object, the left and right mouse key events are processed based on the buttondown flag.


  This idea is clear and feasible. The process of right-clicking an event is as follows:

  HTML right-click event  ----  Flex external functions  -----  Simulated right-click event  ------  Corresponding processing functions

  The specific implementation is as follows:

  1  In the HTML where Flex is located, add
  <  Script >  
  Function  Onnsrightclick (e ){
  If  (E. Which  =   3  ){
  Flextest. openrightclick ();
  E. stoppropagation ();
  }
  Return   False  ;
  }

 Function  Onierightclick (e ){
  If  (Event. Button  >   1  ){
  Flextest. openrightclick ();
  Parent. frames. Location. Replace (  '  Javascript: parent. falseframe  '  );
  }
  Return   False ;
  }


  If  (Navigator. appname  =   "  Netscape  "  ){
  Document. captureevents (event. mousedown );
  Document. addeventlistener (  "  Mousedown  "  , Onnsrightclick,  True );
  }
  Else  {
  Document. onmousedown  =  Onierightclick;
  }

  <  /  SCRIPT>  
  
  2  , Modify flex mxml

  < MX: Application xmlns: MX  =  "  Http://www.adobe.com/2006/mxml  "  Layout  =  "  Absolute  "  Initialize  =  "  Init ()  "  Mouseover  = "  Getmousetarget (Event)  "   >  

  Private  VaR  Mousetarget: displayobject;
  Function  Init ()
  {
  Externalinterface. addcallback (  "  Openrightclick  "  , Openrightclick );
 }


  Function  Getmousetarget (Event: menuevent ):  Void  
  {
  Mousetarget  =  Displayobject(event.tar get );
  }

  Function  Openrightclick ():  Void  
  {
  VaR E: mouseevent  =   New  Mouseevent (mouseevent. mouse_down,  True  ,  False  , Mousetarget. mousex, mousetarget. Mousey );
  Mousetarget. dispatchevent (E );
  }

  Function  Showmouseevent (Event)
  {
  If  (Event. buttondown =   True  )
  Alert. Show (  "  Left  "  );
  Else  
  Alert. Show (  "  Right  "  );
  }


  < MX: Image x  =  "  0  "  Y  =  "  10  "  ID  =  "  Bbb  "  Name  =  " Bbb  "  Source  =  "  Res/15.jpg  "  Mousedown  =  "  Showmouseevent (Event)  "  Height  =  "  247  "/  > 
  

  After the modification is complete, perform the test with confidence.  !  I have tried a lot of methods and I can't do it either. Fortunately, my colleague Zhao Hui discovered the solution. I would like to express my gratitude to him here.  !  

  The specific method is to modify the wmode parameter and set the wmode to opaque or transparent to achieve this effect.
  Ac_fl_runcontent (
  "  SRC  "  ,  "  Playerproductinstall "  ,
  "  Flashvars  "  ,  "  Mmredirecturl =  "  +  Mmredirecturl  +  '  & Mmplayertype =  '  +  Mmplayertype +  '  & Mmdoctitle =  '  +  Mmdoctitle  +  ""  ,
  "  Width  "  ,  "  100%  "  ,
  " Height  "  ,  "  100%  "  ,
  "  Align  "  ,  "  Middle  "  ,
  "  ID  " ,  "  Flextest  "  ,
  "  Wmode  "  ,  "  Opaque  "  ,  //  /// // Note:  
   "  Quality "  ,  "  High  "  ,
  "  Bgcolor  "  ,  "  #869ca7  "  ,
  "  Name  "  , "  Flextest  "  ,
  "  AllowScriptAccess  "  ,  "  Samedomain  "  ,
  "  Type  "  ,  " Application/X-Shockwave-flash  "  ,
  "  Pluginspage  "  ,  "  Http://www.adobe.com/go/getflashplayer  "  
  );

  Description of wmode in Adobe Document:
  Sets the window mode property of the SWF File  For Transparency, layering, and positioning  In  The browser. Valid values of wmode are window, opaque, and transparent.

  Set to window to play the SWF  In  Its own rectangular window on a web page.

  Set to opaque to hide everything on the page behind it.

  Set to transparent so that the background of the HTML page shows through all transparent portions of the SWF file. This can slow animation performance.

  To make sections of your SWF file transparent, you must set the Alpha property 0  . To make your application  '  S background transparent, set the Alpha property on the <mx: Application> tag to 0.

  The wmode property is not supported in all browsers and platforms.

  Now you can use the right-click function flexibly! Passed the test in IE6 and ff2.0
