is there easy way detect closest child element coordinates of mouse click in container?. in case container div ex: <div style="white-space: pre-wrap"> <span>e1</span> <span>\n</span> <span>\n</span> <span>e4</span> <span>e5</span> </div> in above case determine span closest top/left coordinates click took place in div. due line breaks spans don't cover div in click event have access top/left through e.clienty; however, having difficulty traversing spans detect span closest coordinates of click inside div. click handler: function(e){ var yop = e.clienty; } here links might useful document.elementfrompoint : from summary on mdn link: returns element document elementfrompoint method being called topmost element lies under given point. element, specify point via coordinates, in css pixels, relative upper-left-most point in window or frame containing d...

so know itemscontrol generate items top-to-bottom in itemspanel. yes can change sort order , generate them in different ways here's actual problem. if have itemscontrol using itemtemplate multiple uielement 's , use example, stackpanel itemspanel end natural tab order of like; a. 1 2 3 4 5 b. 6 7 8 9 10 c. 11 12 13 14 15 expected, use either order of placement or flowdirection on itemtemplate get; a. 5 4 3 2 1 b. 10 9 8 7 6 c. 15 14 13 12 11 now, question how achieve? (in efficient way) order more like; c. 11 12 13 14 15 b. 6 7 8 9 10 a. 1 2 3 4 5 now if you're thinking.. "ugh, shift + tab dummy..." wish option. requirement using tab, , generating collection in reverse bottom top instead of top bottom , having tab order reversed while they're in control. wise try , hijack shift/tab event , convert tab somehow? if case answers part of question. hopefully someones ran before or enjoys interesting question insigh...

i embed svg in html page in way such is automatically resized (using svg, css, or js) when page resized, while still preserving original aspect ratio. for example, using example w3schools: <svg xmlns="http://www.w3.org/2000/svg" version="1.1"> <circle cx="100" cy="50" r="40" stroke="black" stroke-width="2" fill="red"/> </svg> is possible set svg width = 5% of window width, , have height scaled proportionately? i've tried couple things including preserveaspectratio="xminymin meet" , setting dimensions 100% within <div> container, haven't gotten working yet. any suggestions? you need viewbox -attribute on svg root element, define overall size of svg-image: <svg version="1.1" viewbox="0 0 300 185"> now can set width or height of image via css , scale perfectly.

i want extend 1 of existing "core" modules, core.option : module microsoft.fsharp.core.option let filter predicate op = match op | some(v) -> if predicate(v) some(v) else none | none -> none (i know bind function, think filter method options in case more convenient). but unfortunetely can't use filter method without explicitely open microsoft.fsharp.core namespace: // commenting following line break code! open microsoft.fsharp.core let v1 = 42 let v2 = v1 |> option.filter (fun v -> v > 40) printfn "v2 is: %a" v2 in cases can't use functions module without opening appropriate namespace. f# compiler "opens" predefine (core) namespace automatically (like microsoft.fsharp.core ), not bring scope methods "module extensions" , still should open core namespaces manually. my question is: there workarounds? or best way extend "core" modules create such extensions in cus...

i have class sole responsibility tell me if remote command has returned yes or no , i'm not sure how name it. more specifically, application front end collection of linux commands. communicate linux via ssh. each business operation (ex. getitem, createitem, getitemcount, etc) maps command class. each command class derives base ssh command class handles communication details. my latest command check if remote file of type (let's call doodle type). achieve remote file run through remote program , if program returns 1 or more lines on console file doodle. now i'm struggling how name class. if method , not class call isdoodle . because class involves getting information remote location , derives command base class, i'm tempted use getisdoodlecommand . any thoughts? update while understand suggestion of using commandresult don't think fits in existing pattern use. or maybe don't understand! either way, think original question benefit ...

i know can define like #define less(x, y) if(x < y) so wonder can define if in c++ python-like template or not? such as if x < y: something instead of if(x < y) something to put shortly - no . from cplusplus.com : when preprocessor encounters directive, replaces occurrence of identifier in rest of code replacement. replacement can expression, statement, block or anything. preprocessor not understand c++, replaces occurrence of identifier replacement. what want #define if(x):(y) if(x){##y##}; nevertheless, colon keyword , can't used identifier, breaks macro definition. there's no way escape it.
