An overview of Qt's signals and slots inter-object communication mechanism. Signals and slots are used for communication between objects. The signals and slots mechanism is a central feature of Qt and probably the part that differs most from the features provided by other frameworks. Signals and slots are made possible by Qt's meta-object system.QString QDate:: toString (const QString & format, QCalendar cal = QCalendar ()) const. Returns the date as a string. The format parameter determines the format of the result string. If cal is supplied, it determines the calendar used to represent the date; it defaults to Gregorian. These expressions may be used: Qt Framework is a comprehensive set of C++ library classes and APIs for cross-platform application development. It includes Qt Essentials, Qt Core, Qt GUI, Qt Multimedia, Qt Network, Qt Quick, Qt SQL and more. Explore Qt Features, Qt Add-Ons and Qt Framework Practices for security and performance. For more details on enabling OpenGL with Qt Quick, see scenegraph renderer documentation. Using the Module. Using a Qt module's C++ API requires linking against the module library, either directly or through other dependencies. Several build tools have dedicated support for this, including CMake and qmake. Building with CMakeQt's Layout Classes. Qt's layout classes were designed for hand-written C++ code, allowing measurements to be specified in pixels for simplicity, so they are easy to understand and use. The code generated for forms created using Qt Designer also uses the layout classes.

A line edit allows users to enter and edit a single line of plain text with useful editing functions, including undo and redo, cut and paste, and drag and drop. By changing the echoMode () of a line edit, it can also be used as a write-only field for inputs such as passwords. QTextEdit is a related class that allows multi-line, rich text editing. QT duration is inversely related to heart rate; QT duration increases at slow heart rates and vice versa. Hence, the QT duration must be adjusted for heart rate, which yields the corrected QT duration (QTc). There are several equations for calculating the QTc duration.
