i'm trying hook jquery's animate ability bookmark id on site. when click on link, went bookmark id without animation when clicked same link again, animation works. var titlenav = react.createclass({ handlesubmitclick:function() { $('a').click(function() { $('html, body').animate( { scrolltop: $( $.attr(this, 'href') ).offset().top }, 500); return false; }); }, render: function() { return( <div> <ul classname = "nav"> <li classname = "navworkspace" onclick ={this.handlesubmitclick}><a href="#work">work</a></li> </ul> </div> ); } }); i assume way components called since components not wait on each other. there way fix this? note: using react.js render site. the r

what i'm trying sounds simple haven't seen example or been able find one. i'm adding view navigation controller following way: viewcontrollers.companiesviewcontroller companiesviewctrl = this.storyboard.instantiateviewcontroller ("companyselectview") viewcontrollers.companiesviewcontroller; this.navigationcontroller.pushviewcontroller(companiesviewctrl, true); it bring view list of companies , need user selects company, i'll store information (i this) return previous view , , maybe run event. can point me in right direction how this? thanks :) the simplest solution add event companiesviewcontroller , raise when user selects company. navigation controller pushed companiesviewctrl can subscribe event , notified when company selected. class companiesviewcontroller { public event action<company> companyselected; public override void rowselected (uitableview tableview, nsindexpath indexpath) { //raise companyselec

i have code capture row number in filtered table, things , go next visible row. works great first row. sub test() dim rn long dim cell range dim rng range set rng = sheets("fabricatedparts").range("a:a").specialcells(xlcelltypevisible) rn = sheets("fabricatedparts").usedrange.offset(1, 0).specialcells(xlcelltypevisible).row each cell in rng activesheet .range("b14").value = [parts].cells(rn, [parts[part.]].column) end 'rn = next visible row #???.row next cell end sub when change offset(1, 0) offset(2, 0) still returns row number first visible row(in case 10). looking vba statement return row number next visible row , pass number rn variable. filtered range testing next row number 11, next 165, next 166 etc. thank time. use row number of cell loop. sub test() dim rn long dim cell range dim rng range set rng = sheets("fabricatedp

i've problem what's partially solved, curious (better) solutions.. want canvas fills entire window , resizes if window resized. option 1 (partial solution): according this: https://dlemmermann.wordpress.com/2014/04/10/javafx-tip-1-resizable-canvas/ , this: how make canvas resizable in javafx? i've created (copied) class: public class resizablecanvas extends canvas { public resizablecanvas() { widthproperty().addlistener(evt -> draw()); heightproperty().addlistener(evt -> draw()); } private void draw() { double width = getwidth(); double height = getheight(); graphicscontext gc = getgraphicscontext2d(); gc.clearrect(0, 0, width, height); gc.setstroke(color.red); gc.strokeline(0, 0, width, height); gc.strokeline(0, height, width, 0); } @override public boolean isresizable() { return true; } @override public double prefwidth(double height)

i expected array.array faster lists, arrays seem unboxed. however, following result: in [1]: import array in [2]: l = list(range(100000000)) in [3]: = array.array('l', range(100000000)) in [4]: %timeit sum(l) 1 loop, best of 3: 667 ms per loop in [5]: %timeit sum(a) 1 loop, best of 3: 1.41 s per loop in [6]: %timeit sum(l) 1 loop, best of 3: 627 ms per loop in [7]: %timeit sum(a) 1 loop, best of 3: 1.39 s per loop what cause of such difference? the storage "unboxed", every time access element python has "box" (embed in regular python object) in order it. example, sum(a) iterates on array, , boxes each integer, 1 @ time, in regular python int object. costs time. in sum(l) , boxing done @ time list created. so, in end, array slower, requires substantially less memory. here's relevant code recent version of python 3, same basic ideas apply cpython implementations since python first released. here's code access lis

i have delegate mydelegate used qlistwidget . delegate derived qstyleditemdelegate . 1 of goals of mydelegate place checkbox button on each row of listwidget . done within paint() event of mydelegate : void mydelegate::paint(qpainter *painter, const qstyleoptionviewitem &option, const qmodelindex &index) const { qstyleditemdelegate::paint(painter, option, index); // ... drawing other delegate elements qstyleoptionbutton checkbox; // setting checkbox's size , position // draw checkbox qapplication::style()->drawcontrol(qstyle::ce_checkbox, &checkbox, painter); } at first thought checkbox automatically change state on click, since specified qstyle::ce_checkbox . not case. looks have specify checkbox visual behavior manually. data-wise, when user clicks on checkbox, signal emitted , scene data changed. perform action in editorevent() : bool mydelegate::editorevent(qevent *event, qabstractitemmodel *model, const qstyleoptionviewit

i think i'm being dumb right can't seem think of nice way this: basically creating load of cubes in directx , using vertexpositioncolor store data. store cubes efficiently i'm storing 8 points per cube. thing though, want normal of each face point away such front face's normal (0, 0, 1) , face's normal (0, 0, -1). my problem working out how efficiently 8-point cubes. know 24-point cube representation seems inefficient memory point-of-view. any ideas how can this? preferably in shader or efficient? thanks you can use indecies save memory, 8x4 floats + 4*6 ints each side, 56*4 bytes instead of 96*4 bytes, can do, unless points shared between cubes.

i'm using #403 dynamic forms railcast combined twitter-boostrap-rails 3 , simpleform gems. have custom validations dynamic form. example when 1 field empty use: self.errors.add field, "can't blank" this error can showed iterating on object.errors.full_messages. problem boostrap 3 doesn't add proper css , doen't add text field can't blank under input. can causing issue? i think there problem simple-form picking dynamic inputs because ones not dynamic works!

simple jquery on click event not working iphone6: $(document).on('click tap touchstart', 'div', function(e){}); not working, should do? it seems reasonable ensure there's div on page, , has size large enough click or tap, , you've referenced jquery properly. if do, make sure has content or specify size it, adding background visualize size of object if you're unsure of size of div. if include code, or make jsfiddle reproduces problem can narrow down issue.
