Creating custom widgets
Qt provides ready-to-use essential GUI elements. Qt widgets were not actively developed after Qt Modeling Language (QML) came into existence, so you may require a more specific widget and may want to make it available to others. A custom widget may be a combination of one or more Qt widgets placed together or may be written from scratch. We will create a simple label widget from QLabel as our first custom widget. A custom widget collection can have multiple custom widgets.
Follow these steps to build your first Qt custom widgets library:
