In one of my projects, I would like to have an auto-scrolling textbox. I'm not talking of a textbox that scrolls whenever someone adds a text line, but of something which is like a movie "closing credits" sequence. The textbox would be fullfiled with text and down-scroll slowly without any user action. Is there any existing widget tha...

Btw, this path is a valid one on Windows and is generat...
Hi, I'm trying to set the accessible properties of a QMenu's sub items. I can set the accessible property of the parent menu using setAccessibleName() since it inherits QWidget. Unfortunately, the QActions that you add to the menu aren't widgets child classes, they inherit QObject directly. Is there a way to set the menu items accessi...

Hello! I need to write an application, that detects roaming from one access point to another if I'm connected to WLAN. Unfortunately I couldn't find anything that detects roaming for me. All I could find are some explanations in the Bearer API. One sentence says: The second form of roaming is referred to as Forced Roaming. The sys...
I have a normal VS2008 project that I've been working on for awhile that is doing some OpenGL based stuff. The main window is created with GLUT and until now that has been sufficient for my GUI. Now, however, I want to add a small window of buttons, and I need to do it in a cross platform way, so I decided to use QT. I've installed all...
Is there a way to create a transparent panel as described by the Apple Human Interface Guidelines in Qt 4.6 (built for OS X 10.6/Cocoa)? If not, are there any alternatives similar in look and function? I understand that Qt is a cross platform toolkit, but I want my application to feel as »native« as possible… ...

I'm trying to build a project on Mac OSX, and it's giving me a cryptic error: "[moc_droparea.cpp] Error 1" droparea.cpp is (obviously) a file in the project. I checked that it exists in the project directory and is not corrupted. The file moc_droparea.cpp doesn't show up in the build folder after this error, so I'm assuming it's failin...

The QFuture is iterating over a bidirectional iterator, which I assume is the root of the problem. However, the docs say that QFutureWatcher::progressValue "returns a value between progressMinimum and progressMaximum". I am calling QtConcurrent::filtered like this: QtConcurrent::filtered(myMap.begin(), myMap.end(), filterFn). Does an...
I have three QLineEdit fields, whose content is changing really fast (100/second). Somehow it crashes the application. Maybe it's a bug or I make a mistake. Here is some code: acc[0]->setText(QString("%1").arg(acceleration.x)); acc[1]->setText(QString("%1").arg(acceleration.y)); acc[2]->setText(QString("%1").arg(acceleration.z)); The...
