jsf - primefaces input with tooltip button -


i create input-field-attached-tooltip-button (i don't quite know call it). this:

example of want

when hoover on question mark icon see text.

justification: little icon makes blatantly obvious there's attached field. can see indeed available without moving mouse pointer field. gives user warm fuzzy feeling.

i cannot figure out how in primefaces.

i not know framework has produced example above i'm pretty sure not primefaces.

i'm aware of <p:tooltip> don't think can this.

so here's i've come in primefaces:

my example

(my screencapture not show mouse pointer)

i pretty took balusc's suggestions , created jsf custom component. here's custom component like:

<?xml version='1.0' encoding='utf-8' ?> <!doctype html public "-//w3c//dtd xhtml 1.0 transitional//en" "http://www.w3.org/tr/xhtml1/dtd/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"       xmlns:p="http://primefaces.org/ui"       xmlns:composite="http://java.sun.com/jsf/composite">       <composite:interface>         <composite:attribute name="helptext"/>         <composite:attribute name="show" />     </composite:interface>      <composite:implementation>         <p:button id="help" style="width: 15px; height: 15px" icon="ui-icon-help" rendered="#{cc.attrs.show}"/>         <p:overlaypanel for="help" showevent="mouseover" hideevent="mouseout" hideeffect="fade" >             <p:panel>                 #{cc.attrs.helptext}             </p:panel>         </p:overlaypanel>      </composite:implementation> </html>

and xhtml has produced above screenshot looks this:

<h:form>     <p:panelgrid columns="3" styleclass="noborders">          <p:outputlabel for="mydate" value="date"  />         <p:calendar id="mydate"  pattern="yyyy/mm/dd" />         <customc:fieldhelp helptext="help text date field." show="true" />          <p:outputlabel for="myboolean" value="send ?" />         <p:selectbooleancheckbox id="myboolean" />         <customc:fieldhelp helptext="help text boolean field." show="false"/>          <p:outputlabel for="mypwd" value="your password" />         <p:password id="mypwd" size="30" />         <customc:fieldhelp helptext="help text password field." show="true"/>      </p:panelgrid> </h:form>

seems work fine. can see had reduce size of icon otherwise way big.

some notes:

  • the composite doesn't wrap both icon , field. wraps icon. has downside you'll need 3 column layout , icon not displayed right next field. instead displayed in own column. not wanted.

  • the text conveyed in attribute. has downside cannot contain html markup regardless of fact destination, <p:panel>, happily accept html markup.

  • you can leave out icon using show attribute, - because of 3 column layout - <customc:fieldhelp> need exist each field. clumsy again result of lack of knowledge. :-(

i'm sure can improved upon if 1 knew little more jsf/primefaces myself.

edit

if want icon right next input field (rather in column of own) you'll need <h:panelgroup> tag. can wrap group of elements in tag , <p:panelgrid> (or sibling : <h:panelgrid>) count single element, i.e. occupies 1 cell only. this:

<h:form>     <p:panelgrid columns="2" styleclass="noborders">          <p:outputlabel for="mydate" value="date"  />         <h:panelgroup>             <p:calendar id="mydate"  pattern="yyyy/mm/dd" />             <customc:fieldhelp helptext="help text date field." show="true" />         </h:panelgroup>          <p:outputlabel for="myboolean" value="send ?" />         <h:panelgroup>             <p:selectbooleancheckbox id="myboolean" />             <customc:fieldhelp helptext="help text boolean field." show="false"/>         </h:panelgroup>          <p:outputlabel for="mypwd" value="your password" />         <h:panelgroup>             <p:password id="mypwd" size="30" />             <customc:fieldhelp helptext="help text password field." show="true"/>         </h:panelgroup>      </p:panelgrid> </h:form>

in addition had css tweaking vertical-align: middle icon vertically aligned rest.

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
