Hello, all. I am programming something that needs an interface to Bash. At first I thought I could just use popen or QProcess. ( I'm using QT C++ ) They work fine but I can't get them to run Bash in a tty, which you need if you are going to use anything like sudo, which requires a tty/pty to accept a password. I found some things like ...

I'm currently using Qt's QTextStream to read many different types (read: different extension) of text files. Each "FileReader" class I create starts to have a similar pattern where it needs to readLine() like this: // Get the line's first word as float where each word is delimited by a comma fileData.readLine().split(",")[0].toFloat();...

Whats the best way to deploy a QT app? I've read the documentation hosted at trolltech but is it better to link with a static library or the dynamic libraries and have the user install the framework? I don't really want anyone using my app to have to download a 160mb framework just to run a simple gui frontend. ...
The title describes my problem quite well. The offending line of code: connect(table, SIGNAL(cellChanged(row, 5)), this, SLOT(updateSP())); I can think of no reason why that signal is not valid. I googled around, and found a couple people with the same problem, but the solutions posed there don't work. I'm using Qt 4.5.2 on Ubuntu ...

I'm not having an easy time making a workable mouse pointer interface on the Kindle with Qt (unofficial, of course). The fiveway joystick can't track more than one direction at a time (no diagonal moves), and the screen is too slow to update for good feedback. I've got limited acceleration, but with the screen delay it's very frustrati...

I'm trying to keep track of the textChanged() signal on for handful of QTextEdits. I want to do the same thing regardless of the text edit emitting the signal: uncheck its associated checkbox in a QListWidget if it becomes empty and leave it checked otherwise. The function I have so for is as follows: void MainWindow::changed() { QS...
I can't find a good place to start. It is such a large framework I don't know where to begin. Should it be GUI developer with Qt Creator and all of those tutorials? There are just so many...

I just started using QtCreator tonight, and it seems it puts all of the interface stuff inside of the ui file. I followed a tutorial to create a resource for my icons, then I added them to a menu bar at the top. I need to make a connection when one of them is clicked though, and cannot figure out how to make a callback for it. Am I going...
