if (d->isWidget) { qWarning("QObject::moveToThread: Widgets cannot be moved to a new thread"); return; } 1 2 3 4 我们知道QT是不能在非UI线程创建控件的,所以这个也很好理解,不能将控件移到非UI线程。 三个判断到这里就结束了。下面看看具体的移动动作涉及的几个方面: 执行移动动作 调用move...
This will leverage Qt cross-thread signals to invoke doWork() in the new thread as soon as it starts. Here is how your code should look like: #include <QtWidgets> //QThread wrapper for safe destruction //see http://stackoverflow.com/a/19666329 class Thread : pub...
A new "Abort Cherry-Pick" action has been added for aborting a failed cherry-pick. (#1062) The diff text can now be quickly zoomed using Ctrl + Mouse wheel scroll. This will quickly change the text size within the current session only. (#1029) The Console and Diff widgets learned to ...
Use the QObject::moveToThread() function to change the thread affinity for an object and its children (the object cannot be moved if it has a parent).Calling delete on a QObject from another thread than the thread where it is created (or accessing the object in other ways) is unsafe ...
Widgets MVC Graphics Files Network Concurrent-Computing Plots Other Purpose The goal of this repository is to gather a large number of reusable Qt widgets that may be used in any application. By doing so, we avoid having to reinvent the wheel every time we start a new project and can instea...
