KDE is my posterchild example for saving window and a lot of other state in a config file. There is also some useful data in kmailrc that I'd like to keep when setting up a new machine. But most of the data is state: cat ~/.kde/share/config/kmailrc | grep -A 5 Window ReaderWindowHeight=1334 SearchAndHeaderHeight=388 SearchAndHeaderWidth=1334 composer=523,1624 [HTML Settings] -- [Main Window] Height 1050=1048 Height 1600=500 Height 1680=1624 State=AAAA/wAAAAD9AAAAAAAABo4AAAO5AAAABAAAAAQAAAAIAAAACPwAAAABAAAAAgAAAAEAAAAWAG0AYQBpAG4AVABvAG8AbABCAGEAcgEAAAAA/////wAAAAAAAAAA ToolBarsMovable=Disabled -- [Separate Reader Window] Height 1050=1048 Height 1680=1624 State=AAAA/wAAAAD9AAAAAAAAAgsAAAX7AAAABAAAAAQAAAAIAAAACPwAAAABAAAAAgAAAAEAAAAWAG0AYQBpAG4AVABvAG8AbABCAGEAcgEAAAAA/////wAAAAAAAAAA ToolBarsMovable=Disabled Width 1050=523 Regards, Thomas Koch _______________________________________________ xdg mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/xdg
