  • Wouldn't it be nice to have a type variable referring to the class's instance.

    - by user93197
    I often have a pattern like this: class VectorBase<SubClass, Element> where SubClass : VectorBase<SubClass, Element>, new() where Element : Addable<Element> { Element[] data; public VectorBase(Element[] data) { this.data = data; } public SubClass add(SubClass second) { Element[] newData = new Element[data.Length]; for (int i = 0; i < newData.Length; i++) { newData[i] = data[i].add(second.data[i]); } SubClass result = new SubClass(); result.data = newData; return result; } } class VectorInt : VectorBase<VectorInt, Int32> { } class MyInt : Addable<MyInt> { int data; public MyInt(int data) { this.data = data; } public MyInt add(MyInt t) { return new MyInt(data + t.data); } } interface Addable<T> { T add(T t); } But I would rather just have: class VectorBase2<Element> where Element : Addable<Element> { Element[] data; public VectorBase(Element[] data) { this.data = data; } public SubClass add(SubClass second) { Element[] newData = new Element[data.Length]; for (int i = 0; i < newData.Length; i++) { newData[i] = data[i].add(second.data[i]); } SubClass result = new SubClass(data); return result; } } class VectorInt2 : VectorBase2<Int32> { } Why not make the subclass type available to all classes? Is this technically impossible?

  • Adding a MouseOverHandler to an Element?

    - by JP
    I would like to listen for the mouse over event in GWT 1.6. Since GWT 1.6 has introduced handlers and deprecated listeners I'm unsure as to how I can accomplish this with what little information exists. Note: I have an Element object. That's what I need to add the mouse handler to. I apologize for my lack of clarity. Thanks!

    - by BoDiE2003
    On load, the script is not un-checking the disabled checkboxes, I have tried everything. I have even tried running this code from Chrome Console, and it is working, but not in normal ways. Where is the error?Javascript: document.observe("dom:loaded", function() { $(document.body).select('input').each(function(element) { init(); element.observe('click', function(element) { init(); }); }); loopGroup1(); loopGroup3(); loopGroup4(); }); function init() { $(document.body).select('input').each(function(element) { if (!element.checked) { element.up().removeClassName('yes'); } else { element.up().addClassName('yes'); } if (element.disabled && element.checked) { element.checked = !element.checked; element.up().removeClassName('yes'); } }); }

  • Using ffmpeg to cut up video

    - by Neil
    I am using FFmpeg like this e.g.: ffmpeg -i input.wmv -ss 60 -t 60 -acodec copy -vcodec copy output.wmv to cut out a section of a large file. The -ss part works fine but the -t is ignored. That is, it correctly removes the first -ss seconds but then just keeps going to the end of the input with the copy. Is there a way to use FFmpeg to cut off the end of a video without recoding it?

  • Sort std::vector by an element inside?

    - by user146780
    I currently have a std::vector which holds std::vector of double. I'd want to sort it by the second element of the double vectore. ex: instead of sorting by MyVec[0] or myvec[1] I wat it to sort myVec[0] and myvec[1] based on myvec[0][1] myvec[1][1]. Basically sort by a contained value, not the objects in it. so if myvec[0][1] is less than myvec[1][1] then myvec[0] and myvec[1] will swap. Thanks

  • How do I hide an HTML element before the page loads

    - by Robert
    I have some JQuery code that shows or hides a div. $("div#extraControls").show(); // OR .hide() I initially want the div to be not visible so I used: $(document).ready(function() { $("div#extraControls").hide(); }); However, on the browser, the content loads visible for a second before disappearing, which is not what I want. How do I set the hide the element before the page loads whilst keeping the ability to show hide it dynamically with a script?
