• Does UIScrollView have a special content view for making the scrolling possible?

  - by mystify

  I wonder if UIScrollView has got an "hidden" subview acting as an container for the content. If I scroll a scroll view, is that content view moved up/down in the scroll view? Or is the scrolling offset applied to the bounds of that UIScrollView instance? Or: Does UIScrollView use an additional view as container, or is all content added directly to the view? The documentation doesn't tell much about wether it has a content container or not.

• getting IllegalAccessException when accessing a protected method from parent from inner class

  - by EnToutCas

  I got a very weird problem and a weird solution: class Parent { protected void aProtectedMethod() { doSomething(); } } class Child extends Parent { void anotherMethod() { new SomeInterface() { public void interfaceMethod() { aProtectedMethod(); } }; } } When child.anotherMethod() is run, I got IllegalAccessException at myProtectedMethod(), saying my inner class doesn't have access to the Parent class... However, if I add: protected void aProtectedMethod() { super.aProtectedMethod(); } in my Child class, everything is fine... I wonder why this is?

• Can you make a living as a system programmer?

  - by Helper Method

  Is there still a market for C system programmers? I love Java and some of the newer JVM languages but at the same time I really enjoy low-level system programming under Unix, using C and the GNU toolchain (it makes you feel elitist ;-)). Now I wonder a) is there still a market for C system programmers and b) how much do you earn compared to an app programmer c) is it that much fun in a large scale project?

• What is the lightest way to make a huge chess-like grid?

  - by Sotkra

  Hey there I'm working on a browser-game and I can't help but wonder about what's the lightest way to make the grid/board on which the game takes place. Right now, as a mere sample, I'll show you this: http://sotkra.com/game/ Now, as the grid gets bigger and bigger, the table and its td's create a very heavy filepage which in turn...sucks in more resources from the browser engine and computer. So, is a table with td's the most lightweight way to craft a huge grid-like board or is there something lighter that you recommend? Cheers Sotkra

• Prepopulate jQuery Data in html

  - by Mikael

  jQuery has the very cool feature/method ".data", i wonder if there is a way to have the data in the code so that jQuery can use it when the rendering of html is done. Suppose i have a repeater and looping out children, and i want to add some data to those children without using classes etc. Will i have to add javascript to that repeater just to add stuff to the "data of jquery" or is there some better way?

• Changing keyboard layout on application focus

  - by Anonymous Coward

  Hi Everyone As everybody knows the en-US Keyboard-layout is the best one for programming. So I'd like to use it in my IDEs. But since I live in a non-en-US country I need the de-CH layout for all other applications. Now I wonder if it is possible to set the layout depending to which application currently has the focus. If that is possible, can a human brain adapt to such a behaviour or is it just confusing? cheers, AC
