When enabled, the mouse cursor is hidden when the user types in the
terminal. It is un-hidden when the user moves the mouse, or when the
window loses keyboard focus.
This allows us to detect syntax errors early on, and is also more
efficient since we don't have to re-tokenize the command line every
time the binding is executed.
* Fix col/row calculation in pointer-enter event; we did not take the
margins into account.
* seat->mouse.col,row are now set to -1 if the cursor is inside the
margins. That is, col/row are only ever valid when the mouse is
actually over the grid, and not in the margins.
* Use regular 'left-ptr' mouse cursor when mouse is inside the
margins, to not make the user think he/she can start a selection.
Besides making things clearer, this also fixes a crash that occurred
if you started a selection in e.g. the right margin.
* xcursor always set for all pointers
* xcursor sometimes not updated when it should be
* mouse grabbed state wasn't per seat, but global (i.e. "does at least
one seat enable mouse grabbing")
* selection enabled state wasn't per seat
That is, only call term_kbd_focus_in() if we're the *first* seat
focusing that terminal, and only call term_kbd_focus_out() if we're
the *last* seat that focused it.
Previously, we triggered a theme reload on output changes. This is
completely wrong. We may get a new output with a scale different from
the output the pointer is actually on.
Now, we store the current scale along with the theme. We then trigger
a call to reload the xcursor theme *every* time the pointer enters a
surface. When it does, we use the current scale factor of the terminal
that owns that surface.
If the terminal covers multiple outputs, with different scale factors,
we'll use the largest scale factor. This may not be 100% correct. But
to fix that, we'd need to track which regions of a surface are mapped
on which outputs. Too complicated I say.
When the client is capturing the mouse, selection can only be done by
holding done shift.
This is why a lot of selection functions are no-ops if selection isn't
currently enabled.
However, there are many cases where we actually need to modify the
selection. In particular, selection_cancel().
Thus, only check for enabled selection when we're dealing with user
input.
Bonus: this also fixes a bug where an ongoing selection were finalized
as soon as the user released shift, even if he was still holding down
the mouse button.
Before, we converted each axis event's scroll amount to an integer and
scrolled that many lines.
However, axis events are speed sensitive - very slow scrolling will
result in events with a scroll amount that is < 1.0.
For us, this meant we never scrolled a single line. You could slow
scroll all day if you wanted, and still we would never scroll a single
line.
Fix this by aggregating the scroll amount from axis events until the
scroll amount is > 1.0, and then scroll.
This enables user mappings for the left mouse button with click count
> 3
I.e. it is now possible to create custom quad-click mappings (except
we don't yet support this in footrc).
They aren't really user configurable. At least not yet.
However, with this, we now handle raw key codes just like the normal
key bindings. Meaning, e.g. ctrl+g, ctrl+a, ctrl+e etc now works while
searching with e.g. a russian layout.
Before, when looking for a matching user key binding, we only
matched *symbols*.
This means that the physical keys that generate a specific key binding
is layout dependent. What's worse, it may not even be possible to
generate the key binding at all.
Russian is one such layout, where all the "normal" (us) symbols are
replaced.
By using raw key codes, we can get around this - the key code has a
direct mapping to the physical key.
However, matching raw key codes **only** doesn't always make sense
either. For now, match **both** symbols _and_ key codes. Symbols take
precedence.
TODO: we might have to make this configurable _per binding_.
Note: 'search' mode still uses mostly hardcoded shortcuts that still
have this problem (i.e. ctrl+g doesn't work with a russian layout).
Sway 1.4 is better than 1.2, in that we always have keyboard focus
when we get a keyboard_key() event.
That however is because it doesn't send keyboard_leave() on e.g. a TTY
switch.
Still, this is good enough - foot handles this and doesn't crash. We
are also able to process input without having to refocus the window.
And, Sway master (what will become Sway 1.5) has fixed this for real -
we now get a keyboard_leave() and pointer_leave() event on a TTY
switch. And the corresponding enter events when switching back.
A button may only be mapped to a single action. Detect when the user
tried to map the same button to multiple actions and error out.
To clear a binding (for example, to free up a button from the default
bindings), one can set the action it is bound to to
`NONE` (e.g. `primary-paste=NONE`).
