QWidget inherit from custom QWidget

Question

In Qt C++, is it possible to create a custom QWidget and then reuse this custom QWidget for all QWidget (that inherit all from the custom QWidget) of the project?

Answer 1

Maybe I have misunderstood the question, but you can just create your custom QWidget, then use it everywhere.

class derivedQWidget : public QWidget
{
  Q_OBJECT

  derivedQWidget();
  virtual ~derivedQWidget();
}

class myWidget : public derivedQWidget 
{
  ...
}

class myWidget2 : public derivedQWidget 
{
  ...
}

If the question is: Can we reimplement QWidget?, no you can't.
