问题 I have multiple Tkinter listboxes that I have scrolling together using a single scrollbar, but I'd ALSO like them to scroll together for mousewheel activity over any of the listboxes.

The problem I'm having now is that when the WPF app loses focus, and the web browser opens, the item clicked inside the listbox turns white. Here's the whole ListBox XAML.

问题 I have a ListBox in my wpf window that binds to an ObervableCollection . I want to open the browser if someone clicks on an element of the ListBox (just like a link). Can someone tell me how to do this? I found something with listboxviews, does it only work this way or is there a way by just using the ListBox ?

问题 I have a listbox that is databound to a Collection of objects. The listbox is configured to display an identifier property of each object. I would like to show a tooltip with information specific to the item within the listbox that is being hovered over rather than one tooltip for the listbox as a whole.
