* Grab specific keys
Current code grabs modifier keys and any other keypress. We need to
specifically grab the keycodes we need. xbindkeys and possibly other
programs don't work.
Partially done. Now grabs all our keys unshifted as well as shifted.
Needs a way to tell in config.h what extra modifier is used.
* Feedback window
We need to tell the user the new geometry somehow. Is this what I
want?
The feedback window can also show what workspace we just changed to.
Can we cooperate with a stand-alone program? Write our status to a
root hint or named pipe than can be picked up by another program?
* Changing focus from keyboard
Save the subwindows of the root window and focus each when pressing
modkey + user_key_change. First option always last focused window.
I would like it to work like this: modkey-Tab-Tab-Tab... Release
modkey to focus on a window *and* to remember the window where we
started.
This will also need to work if the change focus with the mouse.
A single modkey-Tab would then get the focus to end up in the window
where we started tabbing or where we last had our focus if changing
with the mouse.
This is now implemented like this:
Always keep the current window as the first element in the current
workspace window list. Always keep the window we focused before it
as the second element.
When we focus on the next window from the current one, the first
Tab always goes to the window we had focus in before.
Currently, we stop tabbing when the MODKEY is released. We might
want to stop tabbing and focus on the new window if we get another
command as well...
I have bound Alt_L explicitly and looking for key release events.
This is a bit ugly. It is possible to ask for what keys give
XCB_MOD_MASK_4 or whatever MODKEY is.
GetModifierMapping
This request returns the keycodes of the keys being used as
modifiers. The number of keycodes in the list is
8*keycodes-per-modifier. The keycodes are divided into eight sets,
with each set containing keycodes-per-modifier elements. The sets
are assigned to the modifiers Shift, Lock, Control, Mod1, Mod2,
Mod3, Mod4, and Mod5, in order. The keycodes-per-modifier value is
chosen arbitrarily by the server; zeroes are used to fill in
unused elements within each set. If only zero values are given in
a set, the use of the corresponding modifier has been disabled.
The order of keycodes within each set is chosen arbitrarily by the
server.
xcb_get_modifier_mapping()
xcb_get_modifier_mapping_unchecked()
xcb_keycode_t * xcb_get_modifier_mapping_keycodes()
xcb_keycode_t *
xcb_get_modifier_mapping_keycodes (const xcb_get_modifier_mapping_reply_t *R /**< */);
xcb_get_modifier_mapping_keycodes_length (const xcb_get_modifier_mapping_reply_t *R /**< */);
How do we re-establish stack order after moving around windows to
focus on? Do we want to?
There is a bug when we change from one ws to another and focuswin
doesn't get reset. That is, focuswin isn't NULL but the
focuswin->wsitem[curws] is empty.
* Virtual screens/workspaces
Partially done. Still needed:
- A window might be on one, *several* or all virtual screens.
We already have a way of fixing a window on all screens (Mod2-f),
but we need a way of saying "stick on this workspace". Perhaps
something like Mod2-a <n>, where <n> is 1--9 for virtual screens.
Better ways? Note that this seems to be mildly incompatible with
the EWMH _NET_WM_DESKTOP hint we're currently using: We will only
be able to save one of the desktops used.
* Hide windows
Instead of iconifying, hide them à la 9wm. Even if we use a key to
hide them, this probably means we have to have a menu to get them
back. Perhaps use an external program somehow? Needs to talk to mcwm
anyway. Unix socket?
* Menu
We might need a menu for hidden windows (see above). Since I'm
probably implementing menu windows anyway, perhaps I should add a
menu with basic window functions, like 9wm and twm. This way, one
might use the window manager without keyboard, if necessary. Not
much work if I have to do the menu anyway... But also chords?
* Chords
Maybe have mouse button chords to do move and resize? Configurable
if on or off?
Idea from Christian Neukirchen.
* Snap to border and screen edge, which favours the edge.
* Gaps on borders for docks, status windows et cetera.
Keep space reserved for Conky, dzen2 et cetera.
Also respect EWMH hints _NET_WM_TYPE_DOCK and _NET_WM_TYPE_DESKTOP.
* Flag to disable dontmoveoff?
* RandR/Xinerama
Get physical screen characteristics for every screen. Maximize, move
to corners should respect the screen it's on. We want a set of
workspaces for every physical screen as well.
xcb_randr_screen_size_t
xcb_randr_screen_size_iterator_t
xcb_randr_get_screen_info_reply_t
xcb_randr_set_screen_size_request_t
How do we handle window moves from one screen to another. Should we
snap to the physical screen's edge and then allow move to continue?
An idea from Christian: Use a huge virtual screen and make physical
screens map to it. Perhaps we can actually manage to have a window
on two physical screens at once?
* Key to move pointer to another physical screen.
* Use xcb-event's event handlers?
* Configurable keys.
* Configuration file.
* Start configurable programs when clicking on root window.
* Handle Urgency hint
Some windows might need attention and marks this with an urgency
hint (for instance, urxvt can generate such a hint when receiving
the BEL character). Do we want to handle it? How do we tell the
user? Can this be done with some stand-alone program instead?
* Support sensible portions of ICCCM and EWMH
EWMH hints that tells applications about active workspace and
focused window...
And a few others.
* Code cleaning
- Obivous cleanup: The event switch is way too big.
- The states are known everywhere. A tight state machine would be
nicer.
- Dispatch table for key bindings instead of keysym->enum->case?
- Use bitfields instead of extra lists for virtual screens?
* Resize behaviour
Better resize behaviour. We want not to accidentally change the
vertical size when changing horizontal size and vice versa.
