nanogui: Thread: nanowm & input focus

hi,

There seems to be some problem with the way nanowm handles the input focus.

consider this case

Window w1 --> child of root window
window w2 --> child of w1

now if i click w2 , and in w1 and w2 button down functions i am setting the 
focus (by using GrSetFocus) to w2 the the focus should remain with w2.
If the nanowm is not running then this is true.
But when nanowm is active the focus is set to a window other than 
w2(probably w1).
Does nanowm have any setfocus (on click) handling code? if yes how does it 
function?

Amit -
You are facing two problems here.  First, for some reason the window
manager is not selecting on the FOCUS_IN or FOCUS_OUT events that
informs it that the focus was s switched.  Secondly, you are facing the
same parenting problem that we discussed before.  When you change the
focus to W2, the window manager should be informed that a particular
container window lost the focus, and it should be informed as to which
window gained the focus.  However, since the window that is getting the
focus is not a container window, it should be traversing backwards
through the tree until it finds a parent that is also a container, and
then drawing the taskbar accordingly.  

Check the nano-X code and see how the GR_EVENT_TYPE_FOCUS_IN and
GR_EVENT_TYPE_FOCUS_OUT events work, and that should help you determine
how the nanowm should be configured.

Amit,
    This is a subtle window manager bug.  I will add it to the
bug list and look into it.  Currently, the window manager
plays with focus a bit on certain mouse downs, and this
may need fine tuning.

Greg
