Hello,
I am currently involved in an effort to make the Sawfish
Window Manager multihead-aware. In this regard, I am
facing a show-stopper, wherein the window of an application
[ say xterm ], appears on the second screen, without the
frame around it, whereas the client-window appearing on the
DefaultScreen has it's frame appropriately generated. The
Client-window is able to receive appropriate events and
assumes focus upon a ButtonPress. Moving the cursor from one
screen to another is also generating the necessary events of
EnterNotify & LeaveNotify.
The sequence of X events that occur in the normal case of the
appearance of a client-window on the Default Screen [alongwith
the frame around it ] is :
FocusIn---> MapNotify ---> VisibilityNotify---> Expose event.
But, in the case of a client-window appearing on the second
screen, the client-window does not get the frame owing to the
following sequence of events :
FocusIn---> MapNotify --->VisibilityNotify--->FocusOut
The above sequence in the second case is suspected to be the
cause of my problem.
Upon reading through the "X" library calls, it becomes evident
that Windows which have "InputOnly" class will not respond to
Expose events.
Moreover, the border-width in XCreateWindow is supposed
to be zero for InputOnly windows. Sawfish uses both classes
while using XCreateWindow, but uses border-width of '0' always.
Could anyone shed some light on the "X" perspective of this
problem. The manner in which appropriate window-creation flags
have to be dealt with, hold the key to this problem.
- Would be glad to hear some clarifications/solutions/opinions.
- Thank you very much
