c# - How to draw a cross? -


i have wpf control.

i need draw below in wpf control. on resizing control, cross should follow size? have type letters below. should able set foreground , background programmatically, binding viewmodel property.

enter image description here

the cross straightforward if use path draw lines/arrows. use viewbox scale container size:

<viewbox>     <grid width="100" height="100">         <textblock text="n" horizontalalignment="left" verticalalignment="center" />         <textblock text="s" horizontalalignment="right" verticalalignment="center" />         <textblock text="e" verticalalignment="top" horizontalalignment="center" />         <textblock text="w" verticalalignment="bottom" horizontalalignment="center"/>         <path stroke="black" strokethickness="1"                 data="m 15,50 l 85,50 m 80,45 l 85,50 m 80 55 l 85,50"                 />         <path stroke="black" strokethickness="1"                 data="m 50,15 l 50,85 m 45,80 l 50,85 m 55 80 l 50,85"                 />     </grid> </viewbox>

now, can wrap above in usercontrol. has properties foreground/background, it's matter of binding them. inside control, use relativesource bindings:

<usercontrol x:class="myproject.controls.compass"     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">      <grid x:name="layoutroot"            background="{binding relativesource={relativesource ancestortype=usercontrol},path=background}">         <viewbox>             <grid width="100" height="100">                 <textblock text="n" horizontalalignment="left" verticalalignment="center"                             foreground="{binding relativesource={relativesource ancestortype=usercontrol},path=foreground}" />                 <textblock text="s" horizontalalignment="right" verticalalignment="center"                             foreground="{binding relativesource={relativesource ancestortype=usercontrol},path=foreground}" />                 <textblock text="e" verticalalignment="top" horizontalalignment="center"                             foreground="{binding relativesource={relativesource ancestortype=usercontrol},path=foreground}" />                 <textblock text="w" verticalalignment="bottom" horizontalalignment="center"                            foreground="{binding relativesource={relativesource ancestortype=usercontrol},path=foreground}" />                 <path stroke="{binding relativesource={relativesource ancestortype=usercontrol},path=foreground}" strokethickness="1"                       data="m 15,50 l 85,50 m 80,45 l 85,50 m 80 55 l 85,50" />                 <path stroke="{binding relativesource={relativesource ancestortype=usercontrol},path=foreground}" strokethickness="1"                       data="m 50,15 l 50,85 m 45,80 l 50,85 m 55 80 l 50,85" />             </grid>         </viewbox>     </grid> </usercontrol>

now can create instances of control (assuming view-model has brush type properties named "foreground" , "background"):

<controls:compass foreground="{binding foreground}" background="{binding background}"/>

html - Sizing a high-res image (~8MB) to display entirely in a small div (circular, diameter 100px) -

java - IntelliJ - No such instance method -

using intellij's 12 ultimate, i'm running following code in debugger: java import play.api.libs.json.jsvalue; public class foo { ... public jsvalue tojson() { ... } public class fooexample { ... foo foo = new foo(); system.out.println("...); //<-- breakpoint at breakpoint, right-clicked source code , picked "evaluate expression," typing in: foo.tojson() . but following error showed up: no such instance method: play.api.libs.json.jsvalue$class.com.foo.foo.tojson () am doing wrong? foo#tojson calls scala code, if matters. edit had breakpoint after instantiation of foo. downvoted it, deserved it. edit my answer no longer valid after op modified question (i.e. moved breakpoint actual is).. a breakpoint hit before line executed. in case foo has not yet been declared or instantiated (i.e. foo constructor has not yet been called). you'll need put breakpoint @ next line (or step on current line) if want evaluate foo .

identifier - Is it possible for an html5 document to have two ids? -

i wondering if html5 element can have 2 ids, this: <button id="thing1" id="thing2" name="button1" onclick="change()">click here</button> or this: <button id="thing1, thing2" name="button1" onclick="change()">click here</button> also, if 1 of ids said 1 thing, , other id said thing, 1 used? tl;dr : no. in versions of html, each element can have 1 id. see the spec : the id attribute specifies element's unique identifier (id). [dom] the value must unique amongst ids in element's home subtree , must contain @ least 1 character. the value must not contain space characters. note: there no other restrictions on form id can take; in particular, ids can consist of digits, start digit, start underscore, consist of punctuation , etc. note: element's unique identifier can used variety of purposes, notably way link specific parts of document usin
