Hi! I want to pass my experiences on to this list regarding the focus management of windows in pages (viewports). The attachment contains my first dirty prototype of fvwm that is fully runnable on my three productive environments (Debian Lenny, fvwm 2.5.26) and partially runnable on my testing environment (Debian Squeeze, fvwm 2.5.31). In the meantime, I succeeded updating the testing environment from fvwm "2.5.30" to fvwm "2.5.31". Some minor problems regarding to fvwm in general still remain (crashing of the pager, ...), but I will face these problems in sequence over the next weeks. My first dirty prototype still contains some German comments, but I will translate them into English later, because I see that more fvwm relevant people cope with English than with German. I don't know if it is welcome that I post entire working configuration settings over this list. If so, then I could post newer versions of my configuration settings later. Apart from "0001_window_decorations", wich is really hacked by me (based on fvwm95), the other config files I programmed using the man pages and further fvwm documentations. Now, the topic about the focussing of windows: My goal is that on a page (a viewport) always one window is focussed (if at least one window exists). The config file "0006_focus" contains this code. This is the working solution. First, I have to set the focus policy: > # set a focus policy > Style * SloppyFocus > Style * GrabFocus Then, I handle the dirty details. > # 1. if a window is already focussed, then do nothing > # > # 2. if no window was focussed, then focus a window under the mouse > # > # 3. if no window was under the mouse, then focus a visible window > # > # 4. if a window was not visible (because the just now disappeared > # window hid it), then try again to focus it > # > DestroyFunc focus_a_window > AddToFunc focus_a_window > + I Current (Focused, CurrentPage) Nop > + I TestRc (NoMatch) Next (AcceptsFocus, CurrentPage, Visible, HasPointer) > Focus > + I TestRc (NoMatch) Next (AcceptsFocus, CurrentPage, Visible) Focus > + I TestRc (NoMatch) Next (AcceptsFocus, CurrentPage) Focus Some more code in "0006_focus" faces a nasty bug of nedit, which prevents me from entering some queries in "Find..." dialogs if the mouse is not exactly over the nedit window. For several years this bug almost drove me mad (I was using KDE 3.X); with fvwm finally I could make a workaround. If this kind of knowledge transfer is welcome, please let it me know. Best regards, Michael
