QWidget — Qt for Python When a widget is used as a container to group a number of child widgets, it is known as a composite widget. These can be created by constructing a widget with the required visual properties - a QFrame, for example - and adding child widgets to it, usually managed by a layout.The above diagram shows such a composite widget that was created using Qt Designer. QToolBox Class | Qt Widgets 5.9 This signal is emitted when the current item is changed. The new current item's index is passed in index, or -1 if there is no current item. Note: Notifier signal for property currentIndex. QWidget *QToolBox:: currentWidget const. Returns a pointer to the current widget, or 0 if there is no such item.

Removing all parameters to the slot function (.h and .cpp) allowed the callback to be found and called. Yes, I'm a Qt n00b. Time to refactor with QSignalMapper :) HTH [SOLVED] Simple QT Question: Connecting Widgets to Slots ... There is no such slot - 'display(5)'. (But there is 'display(int)')Parameters to slots are automatically passed from signals. As there is no 'clicked(int)', it would be best for you to create a new class derived from QLCDNumber and create a new slot in it.
In Qt, QMainWindow and the various subclasses of QDialog are the most common window types. Every widget's constructor accepts one or two standard arguments: QWidget *parent = 0 is the parent of the new widget. If it is 0 (the default), the new widget will be a window.
