Version: (using KDE Devel) Installed from: Compiled sources OS: Linux Minor Bug. When having an extremely long name for something which has no breaks (my test to be sure I wasn't seeing things was with "hkfvhjdnbjkvldfshnbvjkdnbfkvjdnbfjkvnbdkgfbnvhjkgfdnbkjdlnjkvlsdnjkvnelurvhndkfljnvkldfjvsdfbdgfsbgfbgfdbcgbfdgggfbgfgvbfdnghnhg), the properties dialog will not wrap it if it cannot be renamed, even if this leaves the window much wider than the screen. This happens with any read-only file. I tested it with a directory and a mount-point. The mount-point gets a label on a single line. The directory gets a line-edit, but it extends to contain the text. For some reason, if the directory is not read-only, it gets a line-edit which does not extend to fit the text but instead allows for scrolling inside. The window should have a maximum size to avoid this. Normally, I would say it should be about 640 wide. I don't know if it is possible in Qt, but to support translations and huge fonts, it should probably be in ems instead of pixels.
In kde 4.1.72 (svn trunk 885222), the properties dialog uses always the same with, with names that are inside a line edit wich allows to scroll inside, and the directory name is shown with ... if it is too large, and the properties window is resizeable.
Confirming it works here on KDE4.3trunk Also, if the directory is too long and the "..." is added, a tooltip is used so you can hover that label and the full directory path will appear
