This should probably be filed under “Did you know?” Over lunch I was talking to Mark Edington about various UI-isms and he mentioned how the listview column header on Vista has no visual indicator for the splitter between columns. Specifically, he wanted to use the mouse to resize the column headers to so he could see all of the text from the items contained within that column. I mentioned the fact you can double click the splitter to automatically expand the column to the width of the content and he was like “Huh?! Is that just on the File dialog?” Nope, you can double click the splitter on any column header on any standard listview in windows and it will size to the width of the content. He said, “dude, that’s something to blog”. 🙂
[Update May 22, 2007] This is too good not to add to this post. Via Eric van der Gaag pressing Ctrl-+ (Plus key from the keypad) will adjust the size of all the columns in the listview at once! Thanks Eric.
