QToolBar::insertWidget allows to add a QWidget after a specific QAction. Is there any way to add a QAction at a specific position? Removing all actions and then re-adding them again after is my last hope ! ...

Ethics aside, if you're new to QT, play around with it using the non-commercial license (since you obviously wouldn't know at that point if you coul...
Hi all, I am working on a plugin for a Cocoa application, and in order to use existing cpp code we decided to marry the Cocoa plugin with our existing Qt project via Objective-C++, which has been a lot to learn on the fly but is coming along well.

I have used QGraphicsTextItem in my MFC applications for text editing, then converted the results to a bitmap to show in the view (screen). But it has issues when printing. For example, if I print to a PDF file, the text is not scalable since it is a bitmap and the file size is also big. How can I print the QGraphicsTextItem in the MFC ...

Events are handled only when mouse enters zone 2(link text) But I need to handle input in zone 1(where HGE is rendering). What should I do? ...

But what I think the problem is that this application uses Qt for the GUI and I'm trying to fork the worker threads on a secondary thread created by Qt which causes the program to crash - bu...
I am using Qt Creator. When I compile an application, are the .ui files turned into compiled code, or are they read and processed at runtime. I ask simply because I am looking at UI performance and if it is loaded at runtime I would imagine there would be some penalty to that? ...

Hello, We're building a Windows and Mac app using a commercial licence of Qt, which we're building from a git clone. We've got a build setup using Hudson with potentially several build agents, and what I'd like to do for Windows at least is build once then deploy the build Qt to each agent (rather than have to build Qt on each agent)....
I downloaded open-source version of Qt from the site and have compiled it with nmake, but I'm having trouble using it in my projects. It seems that Visual Studio can't find the Qt headers, even though I added the paths to my PATH, INCLUDE, and LIB variables. I tried installing the Qt Visual Studio add-in but it only supports Visual Studi...
