• "Slice" out one element from a python dictionary

  - by BCS

  I have a dictionary: D = { "foo" : "bar", "baz" : "bip" } and I want to create new dictionary that has a copy of one of it's elements k. So if k = "baz": R = { "baz" : "bip" } what I'v got now is: R = { k : D[k] } But in my case k is a complex expression and I've got a whole stack of these. Caching k in a temporary looks about as ugly as the original option. What I'm looking for is a better (cleaner) way to do this.

• java swing, simulate JTable terminateEditOnFocusLost behaviour

  - by blow

  Hi all, i'm using putClientProperty("terminateEditOnFocusLost", Boolean); to make jtable end editing and clear current selected rows when it lose focus or when simply click over an other GUI component. This is very useful, but with "terminateEditOnFocusLost" there are some strange behaviours if it is used with editCellAt and changeSelection. There are also some undesiderable TableModelEvents fired for some fake table updates. So, im looking for an hack to simulate "terminateEditOnFocusLost without using it, is this possibile? Thanks all.
