问题 I have a menu with a lava-lamp like underline that looks like this: The underline slides between links when clicking on them. Try a jsfiddle HERE. My only problem is that if you click outside the menu the underline reverts back to it's original state (18%). But I want the underline to stay on the last clicked link when you click outside the menu.

Is this a known problem of WPF. Does someone else has similar problems? I already opened another thread to this, but no one could help, maybe it was a little to detailed. Therefore this here is the short version. UPDATE It seems that I

问题 I am loading a form and defaulting focus to the first text field. The text field is populated with a default value "PW-". (The first characters of the customers part number like PW-446, PW-9887) They want to just start typing the numbers upon form load instead of clicking to the end of the field, etc to type numbers. The cursor should be blinking at the end of the PW- and ready to go for data input. I have tried many different methods found on StackOverflow with no luck :-( Any ideas? Thanks

问题 Is there any simple approach to let the TreeTableView (or TableView) try to commit values on focus lost? Unfortunatly I didn't succed with any default-implementations of javafx TableCellFactories, which is why I tried my own TreeTableCell implementations and also some different tableCell implementations like the one from Graham Smith, which seemed the most straight forward, since it already implemented a hook for focus lost, but nevertheless the value is never committed and the userchanges
