XSetInputFocus() for clients that have the InputHint; latter fix
discovered by Valery Masiutsin with a PoC patch - solves keyboard input
focus loss for java apps.
triggering event was unmap (with pending destroy) log destroy; we only
need to grab/ungrab the server lock, set WithdrawnState and
XRemoveFromSaveSet clients coming from an unmap event - doing so for
clients coming from destroy are already gone, hence we generate errors.
BadValue) when the modifier is already AnyModifier . Instead alter
xu_btn_ungrab() to ungrab AnyButton/AnyModifier and call it only when a
client is coming into focus in client_setactive(), instead of iterating
over ignore mods - matches how we handle key grabs.
the cc->pwin days - don't redraw on every unhide, resize, and mouse
move/resize Expose event (note, all Expose events trigger a redraw
anyway).
Tested with some finicky X apps I could think of, though I'm sure others
will find more - if so, and they 'lose' the border, please report!
event on the screen's root window, there's no need to pass down the
entire XButtonEvent event, at least to group_menu(), the only callback
which takes an argument at this point; instead use the already populated
screen.
to grab keys in keybindingq. we don't need to ungrab/grab on every
addition to the queue, just once with a complete keybindingq; simplify
grabbing keys per screen (during init) and during a MappingNotify.
while here, change conf_grab_{kbd,mouse} to require only a Window.
validity during the parse phase and not bother adding it to the queue,
instead of each time a client needs to grab (when it's too late);
furthermore, make this a config error, stop parsing and load the
default config.
- merge border/menu color structures/functions since they now both use Xft
- switch xu_xorcolor to operating on XftColor instead of just
XRenderColor (basically adding pixel)
- if color name allocation fails, revert back to default (this, along
with font validation should occur during config parse, but we don't
have screens setup yet - likely to change at some point)
