Python is a great language with many awesome features, but its default GUI package (TkInter) is rather ugly. Besides, who wants to write all that GUI code by hand, anyway? QAbstractItemView — Qt for Python QAbstractItemView class is the base class for every standard view that uses a QAbstractItemModel. QAbstractItemView is an abstract class and cannot itself be instantiated. It provides a standard interface for interoperating with models through the signals and slots mechanism, enabling subclasses to be kept up-to-date with changes to their models.

This course will take you from zero to a level where you can write any Qt C++ Gui application you may want. It is aimed at complete beginners but people with varying levels of experience wishing to learn Qt C++ Gui will equally find it useful. Qt is second to none in the field of building cross platform GUI application based on C++. Threads Events QObjects - Qt Wiki Events and the event loop. We enter Qt's main event loop by running QCoreApplication::exec(); this call blocks until QCoreApplication::exit() or QCoreApplication::quit() are called, terminating the loop. The "wait_for_more_events()" function blocks (that is, it's not a busy wait) until some event is generated. Qt bug? Signal emitted once, slot called multiple times Signal emitted once, slot called multiple times Sweet mother of Jesus, I figured it out. My problems were that a) I didn't at first realize that when you move a class instance to a new thread, you don't move its members, that has to be done separately, and b) you can't use moveToThread at all on a QLocalSocket.

C++11 Signals and Slots! I’ve been asked multiple times how I would implement a signal / slot mechanism in modern C++. Here is the answer! To this signal functions may be connected which accept a string and an integer. A lambda is connected and gets called when the emit method of the signal is called.

Horn loudspeaker - Wikipedia Another type is a woofer driver mounted in a loudspeaker enclosure which is divided by internal partitions to form a zigzag flaring duct which functions as a horn; this type is called a folded horn speaker. Qt 4.6: Porting to Qt 4 You can also define the symbol manually (e.g., if you don't want to link against the Qt3Support library), or you can define QT3_Support_Warnings instead, telling the compiler to emit a warning when a compatibility function is called. Qt Toolkit - Thread Support in Qt The Qt library mutex provides a method for calling Qt methods from threads other than the event thread. Dynamic C++ Proposal
