When I have 2 apps open and one has the focus but I want to execute a command in the other app, it requires a click to regain focus and another to execute the command. Is there some good reason why I couldn’t take focus on MouseOver? I’m working with a WPF app if that is pertinent. TIA
EDIT: Oddly enough the MouseOvers work without focus.
I would not recommend doing this. This is not a standard way of working in Windows, so you will confuse your users. People are used to clicking into an application (or tabbing) to provide focus.
However, this is a configurable setting via the Accessability Tools in Windows. It can be enabled by choosing “Activate a window by hovering over it with the mouse” globally. Let your users specify this behavior if they want it.
