Features.

EMBEDDED SOFTWARE DEVELOPMENT TOOLS Qt Creator - A Cross-platform IDE for Application Development. Qt Creator is a cross-platform integrated development environment (IDE) built for the maximum developer experience. Qt Creator runs on Windows, Linux, and macOS desktop operating systems, and allows developers to create applications across desktop, mobile, and embedded

platforms.

QGROUPBOX CLASS

A group box provides a frame, a title on top, a keyboard shortcut, and displays various other widgets inside itself. The keyboard shortcut moves keyboard focus to one of the group box's child widgets. QGroupBox also lets you set the title (normally set in the constructor) and the title's alignment. Group boxes can be checkable.

QUNDOSTACK CLASS

An undo stack maintains a stack of commands that have been applied to a document. New commands are pushed on the stack using push (). Commands can be undone and redone using undo () and redo (), or by triggering the actions returned by createUndoAction () and createRedoAction (). QUndoStack keeps track of the current command.

QCHECKBOX CLASS

Detailed Description. A QCheckBox is an option button that can be switched on (checked) or off (unchecked). Checkboxes are typically used to represent features in an application that can be enabled or disabled without affecting others.

QPUSHBUTTON CLASS

The push button, or command button, is perhaps the most commonly used widget in any graphical user interface. Push (click) a button to command the computer to perform some action, or to answer a question. Typical buttons are OK, Apply, Cancel, Close, Yes, No and Help. A command button is rectangular and typically displays a text label

QCOMBOBOX CLASS

Detailed Description. A QComboBox provides a means of presenting a list of options to the user in a way that takes up the minimum amount of screen space. A combobox is a selection widget that displays the current item, and can pop up a list of selectable items. A combobox may be editable, allowing the user to modify each item in the list. QABSTRACTTABLEMODEL CLASS QAbstractTableModel Class. The QAbstractTableModel class provides an abstract model that can be subclassed to create table models. More QABSTRACTITEMMODEL CLASS bool QAbstractItemModel:: insertColumn ( int column, const QModelIndex & parent = QModelIndex ()) Inserts a single column before the given column in the child items of the parent specified. Returns true if the column is inserted; otherwise returns false. See also insertColumns (), insertRow (), and removeColumn ().

QLINEEDIT CLASS

Detailed Description. A line edit allows the user to enter and edit a single line of plain text with a useful collection of editing functions, including undo and redo, cut and paste, and drag and drop (see setDragEnabled ()). By changing the echoMode () of a line edit, it can also be used as a "write-only" field, for inputs such as

passwords.

QSTRING CLASS

Detailed Description. QString stores a string of 16-bit QChars, where each QChar corresponds to one UTF-16 code unit. (Unicode characters with code values above 65535 are stored using surrogate pairs, i.e., two consecutive QChars.). Unicode is an international standard that supports most of the writing systems in use today. It is a superset of US-ASCII (ANSI X3.4-1986) and Latin-1 (ISO 8859-1

QEVENTLOOP CLASS

Detailed Description. At any time, you can create a QEventLoop object and call exec () on it to start a local event loop. From within the event loop, calling exit () will force exec () to return. See also QAbstractEventDispatcher.

QTIMER CLASS

Detailed Description. The QTimer class provides a high-level programming interface for timers. To use it, create a QTimer, connect its timeout() signal to the appropriate slots, and call start(). From then on, it will emit the timeout() signal at constant intervals.. Example for a one second (1000 millisecond) timer (from the Analog

Clock example):

A menu widget is a selection menu. It can be either a pull-down menu in a menu bar or a standalone context menu. Pull-down menus are shown by the menu bar when the user clicks on the respective item or presses the specified shortcut key. Use QMenuBar::addMenu () to insert a menu into a menu bar. Context menus are usually invoked by some special

QFILEDIALOG CLASS

This is a convenience static function that returns an existing file selected by the user. If the user presses Cancel, it returns an empty url. The function is used similarly to QFileDialog::getOpenFileName (). In particular parent, caption, dir, filter, selectedFilter and options are used in the exact same way.
