Full-screen mode is pleasantly exclusive, so we only need to send the
incoming mouse events to the active full-screen window.
This fixes an issue where clicking on the area normally covered by
the menubar while in full-screen mode would not send mouse events to
the full-screen window.
Normally we walk the window stack to see if a given dirty rect is
covered by an opaque window. When the active window is full-screened,
we can skip this check and just unconditionally paint the window.
This fixes an issue where windows with higher inherent z-order (like
the taskbar and menu windows) would get cursor ghosting in them while
a normal window was full-screened.
Fixes#2289.
Core::Object derived objects should always have private constructors
and use construct() for construction. This prevents accidentally
keeping them in non-reference-counting containers.
Previously opening the shutdown dialog and cancelling out of it would
cause SystemMenu to exit due to the exit-when-there-are-no-more-windows
mechanism in GUI::Application. Fix this by opting out of it.
Previously, we would concatenate all the commands together:
```
> sleep 5
echo well
echo hello
echo friends
> echo wellecho helloecho friends
```
Also renames some variables to be more descriptive.
read_block() and write_block() now accept the count (how many bytes to read
or write) and offset (where in the block to start; defaults to 0). Using these
new APIs, we can avoid doing copies between intermediary buffers in a lot more
cases. Hopefully this improves performance or something.
The "ready to write" notifier we set up in generic socket connection is
really only meant to detect a successful connection. Once we have a TCP
connection, for example, it will fire on every event loop iteration.
This was causing IRC Client to max out the CPU by getting this no-op
notifier callback over and over.
Since this was only used by TLSv12, I changed that code to create its
own notifier instead. It might be possible to improve TLS performance
by only processing writes when actually needed, but I didn't look very
closely at that for this patch. :^)
We should always stay on the only line when selecting in a single-line
editor, instead of requiring the user to keep the cursor inside the
text when selecting.
This broke with the variable-width font changes.
Previously we would sometimes leave some pixels from an old selection
rect on screen after clearing the selection. It was because the line
content rect was smaller than the visual selection rect, and we were
using the line content rect for invalidations.
