• Creating a console in Java

  - by DeadMG

  When I try to use java.lang.System.console(), I get a null pointer. I can still write to out and read from in, but this only works when I run straight from my IDE. When I run the .jar file directly, nothing happens. How can I create a console like I'd see using std::cout for use in Java?

• Are there any good books to learn C++ if you already know Java and C#

  - by JF LR

  Hi, I would like to know if you have any good books that teach C++ programming without repeating basic stuff. In fact, I already well know Java and C#. I also have a basic knowledge in C and assembly, so I understand a little bit pointer arithmetic, manual memory management and heap based allocation. I was looking at O'Reilly's C++ in a Nutshell and was also wondering if this book would be a good choice. Thank you

• How to ignore events in html table

  - by Yaron

  Hello, I have a transparent table with width:100% which contains some html content. I use the table in order to position a content element on the screen center. The table captures mouse events, and the user can't press on links which are positioned beneath it (although it is transparent). Is there a way to tell the browser to ignore events on the table? I want to capture events only from the content inside the table (and from the rest of the site). Thanks Yaron

• Generic transparent Qt widget that can catch clicks?

  - by Pieter

  I've figured out how to use QPainter to draw rectangles. Now I want to have a drawing area where if the user clicks, a 1x1 rectangle is drawn where the mouse pointer is. To accomplish this, I assume I need a transparent Qt widget that supports the clicked() signal. How do I make such a transparent widget? Or is there something else I can use? Perhaps I can only use the window's clicked() signal?

  Hello I would like to be able to cancel a drag operation with the Escape key.

Thanks!

• Cocoa equivalent of diskEvt/kEventClassVolume?

  - by tewha

  We have a drop-down menu of volumes in our UI, and I'd like to update it when a new disk is mounted. In the Classic days, this would involve watching for a diskEvt event. In Carbon, I think this was kEventClassVolume. What's the Cocoa equivalent? (A pointer into Apple's documentation on this would satisfy the question. I've been unable to find anything!)
