The assertion succeeds if the predicate returns true when applied to the given arguments, and fails otherwise. When the assertion fails, it prints the value of each argument. In either case, the arguments are evaluated exactly once. Boost Getting Started on Unix Variants - 1.61.0

Call waitForStarted() to make sure the process has started (or has failed to start) and those signals have been emitted. Note: No further splitting of the arguments is performed. Windows: The arguments are quoted and joined into a command line that is compatible with the CommandLineToArgvW() Windows function.
Section 17 Assertions - Michigan Section 17 Assertions 17.1 Introduction (informative) SystemVerilog adds features to specify assertions of a system. An assertion specifies a behavior of the system. Assertions are primarily used to validate the behavior of a design. In addition, assertions can be used to pro-vide functional coverage and generate input stimulus for validation. #include <QApplication> #include <QMainWindow> #include

Qt 5 中信号槽新语法的实现 - DevBean Tech World 好吧，，在使用Qt5新版的信号槽新语法的时候，发现最后一个槽在有函数重载的时候，，几乎编译不过了，，好蛋疼，这个要 connect(&obj, &SenderObject::signal1, this, [this, &status, &obj] … connect(&obj, &SenderObject::signal1, this, [this, &status, &obj] (int test) { status = 2; QCOMPARE(sender(), &obj); }, Qt::QueuedConnection);
Signals and slots are loosely coupled: A class which emits a signal neither knows nor cares which slots receive the signal. Qt's signals and slots mechanism ensures that if you connect a signal to a slot, the slot will be called with the signal's parameters at the right time. Signals and slots can take any number of arguments of any type.
