jsf/primefaces load indicator during init of the bean -


in jsf/primefaces project, have lot of data loading in init (postconstruct) method of beans. that's why show gif indicator during bean load.

i tried primefaces , ajax status (programmatic version of showcase)

http://www.primefaces.org/showcase/ui/ajaxstatusscript.jsf

so added template of project

<p:dialog modal="true" widgetvar="loadwidget" header="status"     draggable="false" closable="false">      <p:graphicimage value="../images/ajaxload.gif" /> </p:dialog>

i able call loadwidget.show(); @ beginning of init method of bean , loadwidget.hide(); @ end.

do have idea , how fire javascript display loading gif? thanks

edit

i add tried this. here part of template include content of page. it's not working either p:dialog included before or after content.

<div class="content">     <script>loadwidget.show();</script>         <ui:insert name="body" />     <script>loadwidget.hide();</script> </div>

the console says loadwidget not defined

edit2

i try explain how project works. helpful.

here template

<html ... >  <f:view contenttype="text/html">      <h:head> ... </head>      <h:body>         <ui:insert name="header" />         <ui:insert name="menu" />         <ui:insert name="body" />         <ui:insert name="footer" />         ... <!-- other things -->     </h:body> </f:view>    </html>

then each page defines body. example of page.

<html ... >  <ui:composition template="mytemplateabove">      <ui:define name="body">              <h:outputtext value="#{beanofmyfirstpage.mytext}" />             <p:commandbutton action="#{beanofmyfirstpage.gotoanotherpage}" />             ...         </ui:define> </ui:composition>  </html>

then each page linked bean extends basebean.

@managedbean(name = "beanofmyfirstpage") @viewscoped public class beanofmyfirstpage extends basebean {     // attributes + getters , setters      @postconstruct     public void init() {         super.init();         ... // actions take time cause of db requests example     }      public void gotoanotherpage() {         navigation.handlenavigation(facescontext.getcurrentinstance(), null, "mysecondpage");     }      // methods }

and common bean

public class basebean {      @postconstruct     public void init() {         super.init();         // general actions beans     }  }

i have solution!

it simple , there nothing primefaces or jsf bean construction process.

i added in template (that included every pages)

<div id="nonajaxload">     <img src="../images/ajaxload.gif"/> </div>

then added css below move fixed bottom right of page

#nonajaxload {     width: 50px;     height: 50px;     position: fixed;     bottom: 30px;     right: 30px; }

and make magical, added script

<script>     $(document).ready(function(){         $('#nonajaxload').hide();     });      $(window).bind('beforeunload', function() {         $('#nonajaxload').show();      }); </script>

so when leave page, loading indicator shown , when other page loaded, it's hidden.

thanks helped @andy

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
