(We could have allowed values down to -9 but chose not to.) If the arguments are illegal, we use Qt's Qt Global::q Warning() function to issue a warning to the user and return immediately.Qt Global::q Warning() is a This makes our lcd numbers look way better.

This is the mechanism that Qt offers for dispaching events.

This signals are called every time an event is dispatched to a virtual function.

For example if Qt_widget receives mouse Press Event(QMouse Event *e) emits s_mouse Press Event(e).

(For this widget only the background and text colors will actually be used.) We then call set Auto Fill Background(true) to tell Qt fill the background automatically.

The Qt:: Color is specified as a RGB (red-green-blue) triplet, where each value is between 0 (dark) and 255 (bright).

Map the widget coordinates to the interval defined by the rectangle with given coordinates.

This method should be called after resize() from QWidget.You should use clear_history() method from Qt_widget_standard_toolbar or the clear() public slot from Qt_widget_history object. You should use the backward() and forward() methods of Qt_widget_history object, or the back() and forward() public slots from Qt_widget_standard_toolbar object.Deprecated: This slots permit to walk into history. Locks the widget, keeping the widget from being refreshed.In the given example, that is found in tutorial/Qt_widget/tutorial1/tutorial1.C, we create an object of type Qt_widget and then we use the operators for output and the manipulators to show some of the widget's functionality.Before drawing the layers, redraw clear the screen and emit redraw_on_back(). You can set the properties of the functions through this functions as well as with the help of manipulators described later.
