The run script is not in Kernel/ anymore, let's move `.bochsrc` in Meta/
so that it can be used with the new build system.
Also make bochs use `grub_disk_image` instead of `_disk_image`
We don't need to copy `run.sh` and modify it: we can just set
environment variables.
Now, we don't have to modify two files everytime we make a change to the
run.sh script.
Also make SERENITY_BUILD overridable with environment variables,why not?
literal methods; add EnvrionmentRecord fields and methods to
LexicalEnvironment
Adding EnvrionmentRecord's fields and methods lets us throw an exception
when |this| is not initialized, which occurs when the super constructor
in a derived class has not yet been called, or when |this| has already
been initialized (the super constructor was already called).
This is a helper function based on the getter/setter definition logic from
ObjectExpression::execute() to look up an Accessor property if it already
exists, define a new Accessor property if it doesn't exist, and set the getter or
setter function on the Accessor.
fixes#2575
The extra ResizeEvent would be handled after on_rect_change, and would
reset the size of main_widget to what it was before the resize.
Bonus: Less unnecessary events.
Consider the following: upon instanciation of a GUI::SpinBox, its
internal value and displayed value are both 0. When calling `set_min(1)`
on it (same as `set_range(1, max())`), the internal value gets clamped
to 1 correctly, but "0" is still displayed by the widget.
The displayed value is now updated accordingly to the internal value
when it gets clamped.
We now remember the last candidate fragment when hit testing past the
right end of text and use that as the fallback result if nothing else
matches. This makes it possible to drag-select outside the line boxes
in a way that feels mostly natural. :^)
We use this to ensure that we're always working with a selection where
the start() is before the end() in document order. That simplifies all
the logic around this.
Text selection currently works at the LayoutNode level. The root of the
layout tree has a LayoutRange selection() which in turn has two
LayoutPosition objects: start() and end().
A LayoutPosition is a LayoutNode + a text offset into that node.
We handle the selection painting in LayoutText::paint_fragment(), after
the normal painting is finished. The basic mechanism is that each
LayoutFragment is queried for its selection_rect(), and if a non-empty
rect is returned, we clip to it and paint the text once more.
