for example, when ismouseover, change background of ellipse. way find ellipse can set fill property way have set style? there better way lay out?

cheers,
berryl

<style x:key="closecrosstogglebuttonstyle" targettype="{x:type togglebutton}">  <setter property="contenttemplate">       <setter.value>         <datatemplate>              <grid background="transparent">                  <!-- background of button, ellipse. -->                 <ellipse x:name="theellipse" />                  <!-- path renders cross. -->                 <path x:name="thecross"...              </grid>          </datatemplate>     </setter.value> </setter>  <setter property="template">     <setter.value>         <controltemplate targettype="{x:type togglebutton}">             <contentpresenter x:name="thecontent"/>             <controltemplate.triggers>                 <trigger property="ismouseover" value="true">                     <setter property="ellipse.fill" value="{staticresource hoverbackgroundbrush}" />                     <setter property="path.stroke" value="{staticresource hoverforegroundbrush}"/>                 </trigger>             </controltemplate.triggers>         </controltemplate>     </setter.value> </setter>

ok, working

 <setter property="template">     <setter.value>         <controltemplate targettype="{x:type togglebutton}">             <grid background="transparent">                 <!-- background of button, ellipse. -->                 <ellipse x:name="theellipse" />                 <!-- path renders cross. -->                 <path x:name="thecross"                       ...                 </path>              </grid>             <controltemplate.triggers>                 <trigger property="ismouseover" value="true">                     <setter targetname="theellipse" property="fill" value="{staticresource hoverbackgroundbrush}" />                     <setter targetname="thecross" property="stroke" value="{staticresource hoverforegroundbrush}"/>                 </trigger>                 <trigger property="isenabled" value="false">                     <setter property="visibility" value="collapsed"/>                 </trigger>                 <trigger property="ispressed" value="true">                     <setter targetname="theellipse" property="fill" value="{staticresource pressedbackgroundbrush}" />                     <setter targetname="theellipse" property="stroke" value="{staticresource pressedborderbrush}" />                     <setter targetname="thecross" property="stroke" value="{staticresource pressedforegroundbrush}"/>                 </trigger>             </controltemplate.triggers>         </controltemplate>     </setter.value> </setter>

in controltemplate.triggers can manipulate controls inside contenttemplate, not have access elements contenttemplate out of template.

you can example below (i changing button image...):

<setter property="template">     <setter.value>         <controltemplate targettype="{x:type button}">             <grid width="{templatebinding width}" height="{templatebinding height}">                 <image x:name="imgbackground" source="{staticresource uparrowimagenormal}" stretch="none"/>             </grid>             <controltemplate.triggers>                 <trigger property="ispressed" value="true">                     <setter targetname="imgbackground"                             property="source" value="{staticresource uparrowimageispressed}"/>                 </trigger>                 <trigger property="isenabled" value="false">                     <setter targetname="imgbackground" property="source" value="{staticresource uparrowimagedisabled}"/>                 </trigger>             </controltemplate.triggers>         </controltemplate>     </setter.value> </setter>

unfortunately not know ways apply triggers data template. believe can apply trigger in contentpresenter...

correction, seems can use (sample):

<button x:name="btntest" height="23" width="75"  horizontalalignment="left"  verticalalignment="top" verticalcontentalignment="stretch" horizontalcontentalignment="stretch">             <button.contenttemplate>                 <datatemplate>                     <rectangle x:name="t" fill="azure" verticalalignment="stretch" horizontalalignment="stretch"/>                     <datatemplate.triggers>                         <trigger property="ismouseover" value="true">                             <setter targetname="t" property="fill" value="black"/>                         </trigger>                     </datatemplate.triggers>                 </datatemplate>             </button.contenttemplate>         </button>

c++ - Using OpenSSL in a multi-threaded application -

-
i have been writing soap client application in c++ on ubuntu using openssl https transport , pthreads threading. have number of threads - 1 central data acquisition thread periodically gets worker threads make soap requests via shared mutex protected queues. reading documentation openssl found is openssl thread-safe? in openssl faq describes mechanisms required ensure thread safety when using openssl. implemented , works fine. the reason question conceptual difficulty really. thinking implementing same functionality application has already, instead of using threads, create 2 seperate applications : 1 worker thread (of multiple copies running) , main data acquisition thread. use tcp sockets communicate between 2 rather mutex protected queues. may bad idea not important - confusing me would have implement same functions required ensure openssl thread safety in second approach or not? my guess not have , treated independent (indeed surely must many applications use openssl) re...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
