I am trying to use the tree view widget but I cant seem to scroll down to configure the options in the first tab 'Tree Configuration'. Does anyone have any idea how I could scroll down to get to the other configuration options?
There are just too many options on a single tab. Don't double click the widget but single click it and access the options in the properties panel of the designer.
Also try a screen with a bigger resolution if available. The organization of the options in the widget popup are more understandable then the properties window.
