The PaneSlider is a component from dtkWidgets that displays widgets and that can slide on the right to display more menus. Currently this PaneSlider is a bit problematic. There are some annoying bugs related to sliding, where it only slide halfway or where widgets are not displayed . To find your way in all the classes in the project, I made a map of classes. You’ll find for every class its slots, signals, methods and mother class (in red). On the top-right corner you’ll find the file and the line number to find the class easily.
