wpf controls - How to retain default hover effect for my custom WPF RepeatButton -

-

when create custom wpf control, retain usual default appearance , effects. example, includes default blue hover on button.

i have created custom tabcontrol scrollable tabs. whatever reason, repeatbutton on each side (i.e. left , right scroll arrows) have no hover effect. have found several tutorials tell me how create own hover effect controls, unfortunately these examples replace background different color (and looks different having animation fades in transparent blue while keeping underlying background). how can hover effect? there way can access standard hover effect (might storyboard?)?

edit: have discovered if remove custom style put on repeatbutton, default hover effect. perhaps question -- how did destroy hover effect, , how mildly modify appearance without destroying it? below style borked hover effect-

                        <style x:key="tabscrollerrepeatbuttonstyle" targettype="{x:type repeatbutton}">                         <setter property="template">                             <setter.value>                                 <controltemplate>                                     <border x:name="testtest" background="{templatebinding background}" borderbrush="{templatebinding borderbrush}" borderthickness="1" margin="1,0" cornerradius="2">                                         <contentpresenter horizontalalignment="center" verticalalignment="center" content="{templatebinding contentcontrol.content}"/>                                     </border>                                 </controltemplate>                             </setter.value>                         </setter>

the best way attack problems these fire expression blend , 'edit template' control want copy styles from. doing scrollbar show default style , can copy relevant bits custom control style.

javascript - Enclosure Memory Copies -

function myclass() { //lots , lots of vars , code here. this.bar = function() { //do numerous enclosed myclass vars } this.foo = function() { alert('hello'); //don't enclosed variables. } } each instance of myclass gets own copy of bar , foo, why prototyped methods use less memory. however, know more memory use of inner methods. it seems obvious me (1) below must true. agree? not distinct myclass instances have own distinct copies of bar, must have own distinct copies of myclass enclosure. (or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

(in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
