plans for XplatUIX11.cs:
|
|
|
|
- 1 thread watching X socket, doing nothing but
|
|
XNextEvent/hwnd.Queue.Enqueue (with minimal motion
|
|
compression/key repeat detection)
|
|
|
|
- figure out how to deal with the selection events, since they
|
|
busy loop waiting on a response from the X socket. maybe
|
|
block that thread with an event and wake it up when the
|
|
event thread get enough info?
|
|
|
|
- Idle event raised once regardless of how many thread queues
|
|
we have (should it come from the X event thread?)
|
|
|
|
- X11Hwnd which caches (amongst other things) the properties
|
|
for the toplevel window so we can avoid doing all those
|
|
XChangeProperty things on every single UpdateStyle call.
|
|
|
|
- have RULES for things (like "do not call this function
|
|
except from ...", etc) and make sure they're enforced.
|
|
|
|
- SendMessage.. can't we just insert the right message on the
|
|
hwnd's queue instead of using SendAsyncMethod?
|
|
|
|
- what's the difference between PostMessage and SendMessage?
|
|
|
|
- clean up the MESS that is:
|
|
GetWindowState
|
|
SetWindowState
|
|
|
|
and especially:
|
|
SetHwndStyles
|
|
SetWMStyles
|
|
DeriveStyles
|
|
the Style handling in CreateWindow
|
|
|
|
- multiple screens? do we care? xinerama foo?
|
|
|
|
- fix the mostly static, somewhat instance nature of
|
|
XplatUIX11.cs. Either make it static, or make it an
|
|
instance.
|
|
|
|
- we need to rethink the expose event handling. right now
|
|
expose events are only handled once all the other events in
|
|
the queue are handled. So, if you're resizing quickly you
|
|
get no redraws until you're done. maybe look at the
|
|
_NET_WM_SYNC_REQUEST protocol (for the resize/redraw case
|
|
specifically). Also, the current expose handling has us
|
|
accessing the invalid list/rectangle from multiple threads.
|
|
|
|
- factor out ALL knowledge of the multiple windows
|
|
(client/whole) into the X11Hwnd class, so we can try to
|
|
factor it out.
|
|
|
|
- clean up the systray icon stuff - right now it destroys (!)
|
|
the client_window and sets client_window == whole_window.
|
|
ugh.
|
|
|
|
- hwnds should keep track of the width/height they report to
|
|
SWF as well as the x window's width/height. That is, we
|
|
should allow hwnds with 0,0 width/height even though X
|
|
doesn't allow it. There's some "zero_size" stuff in Hwnd,
|
|
but it still appears impossible to have 0,0 sized Widgets.
|
|
|
|
- window (subwindow, really) destruction should move to Hwnd
|
|
if possible.
|
|
|
|
- remove 90% of "lock (XlibLock)" usage. It's not really
|
|
needed at all, except perhaps to synchronize the
|
|
XEventThread and the PeekMessage/GetMessage methods.
|
|
|
|
- the big synchronization problem now is the XEventQueue
|
|
class. I think all queue operations need to be done while
|
|
holding a lock, as the events are queued from the
|
|
XEventThread and dequeued from GetMessage.
|
|
|
|
possible classes:
|
|
|
|
- XplatUIX11 (creates the first (only?) X11Display class.
|
|
Most calls should just get the hwnd/display and make a
|
|
method call)
|
|
|
|
- X11Display (manages the display handle, creates the event
|
|
thread, keeps ref to an X11Atoms and the X11RootHwnd)
|
|
|
|
- XEventThread (does this need to be a separate class? can
|
|
probably just be a method in X11Display)
|
|
|
|
- X11Hwnd (move all the style translation here? handles
|
|
property changes and caches them. window title here too)
|
|
|
|
- X11RootHwnd (add the special root window property stuff
|
|
here)
|
|
|
|
- X11Atoms (per display atom list. should these be properties
|
|
or fields? fields probably, with the builtins as constants).
|
|
|
|
- Xlib (the pinvoke wrapper for Xlib calls)
|
|
|
|
window managers we need to test again:
|
|
|
|
- metacity on SLED/SUSE
|
|
- metacity on ubuntu edgy
|
|
- compiz on SLED
|
|
- compiz HEAD
|
|
- beryl? or should compiz be enough?
