There's the "font_type" property which currently only handles
fixed-width yes/no, so until we get a proper font type enum and
associated enum property, this is better to use from GML instead of a
special case in the GML compiler.
Since Core::Object properties are really only used by GML now that the
Inspector is long gone, there's no need for these to pollute
Core::Object.
This patch adds a new GUI::Object class to hold properties, and makes
it the new base class of GUI::Window, GUI::Widget and GUI::Layout.
The "instantiate an object by name" mechanism that GML uses is also
hoisted into GUI::Object as well.
Previously, calling `.right()` on a `Gfx::Rect` would return the last
column's coordinate still inside the rectangle, or `left + width - 1`.
This is called 'endpoint inclusive' and does not make a lot of sense for
`Gfx::Rect<float>` where a rectangle of width 5 at position (0, 0) would
return 4 as its right side. This same problem exists for `.bottom()`.
This changes `Gfx::Rect` to be endpoint exclusive, which gives us the
nice property that `width = right - left` and `height = bottom - top`.
It enables us to treat `Gfx::Rect<int>` and `Gfx::Rect<float>` exactly
the same.
All users of `Gfx::Rect` have been updated accordingly.
I had to add a set_title(String) helper function for ImageEditor because
TabWidget requires it. This is a temporary fix and will be handled in
subsequent commit.
This class had slightly confusing semantics and the added weirdness
doesn't seem worth it just so we can say "." instead of "->" when
iterating over a vector of NNRPs.
This patch replaces NonnullRefPtrVector<T> with Vector<NNRP<T>>.
This just calls Layout::try_add_spacer(), but saves you having to access
the Widget's Layout directly.
We verify that the Widget has a Layout, since it would be a programming
error if we tried to do so without one.
The existing `load_from_gml()` methods look the same as before from the
outside. Inside though, they now forward to `try_load_from_gml()` which
returns Error when things go wrong. It also now calls the `try_create()`
factory method for Objects instead of the `construct()` one.
This will make it easier to support both string types at the same time
while we convert code, and tracking down remaining uses.
One big exception is Value::to_string() in LibJS, where the name is
dictated by the ToString AO.
We have a new, improved string type coming up in AK (OOM aware, no null
state), and while it's going to use UTF-8, the name UTF8String is a
mouthful - so let's free up the String name by renaming the existing
class.
Making the old one have an annoying name will hopefully also help with
quick adoption :^)
and the CaptureInput mode. They are a source of unneeded complexity
in WindowServer and have proven prone to regressions, so this patch
replaces them with a simple input preemption scheme using Popups.
Popup windows now have ergonomics similar to menus: When open,
a popup preempts all mouse and key events for the entire window
stack; however, they are fragile and will close after WindowServer
swallows the first event outside them. This is similar to how combo
box windows and popups work in the classic Windows DE and has the
added benefit of letting the user click anywhere to dismiss a popup
without having to worry about unwanted interactions with other
widgets.
with the CaptureInput WindowMode. This mode will serve the same
function as accessories: redirecting input while allowing parent
windows to remain active.
Widget::handle_leave_event() hides the tooltip if one is shown. That's
usually fine and hides the widget's tooltip, but it can happen that
another widget managed to show a tooltip after the Leave event was
triggered and before it's processed.
Thus change handle_leave_event() to only hide the tooltip if it was show
by the widget.
Fixes the case where this could happen in the flame graph in Profiler
when moving the mouse over the tooltip window itself #14852.
Each of these strings would previously rely on StringView's char const*
constructor overload, which would call __builtin_strlen on the string.
Since we now have operator ""sv, we can replace these with much simpler
versions. This opens the door to being able to remove
StringView(char const*).
No functional changes.
This function is intended to propagate layout changes upwards in the
widget hierarchy. Widgets that can know what to do with this
information without causing a full layout invalidation (i.e. just
because one of their child widgets changed layout/size, doesn't
necessairily mean that they have to change their layout/size) can
override this and prevent a full relayout and redraw.
Effective sizes are the ones that are actually to be used for layout.
They are just their respective propertys value, or the value returned
by the calculated_<min/preferred>_size, when the respective property
is set to shrink or fit.
The "calculated" values in turn are specific to the widget. Container
widgets for example can calculate their values depending on their
layout and child widget requirement.
Simple widgets like labels and buttons can for example calculate their
values based upon their current text.
This is a bit of a hack, but it is an easy way to finally get spacers
into GML.
This will translate well if spacers are later to become child objects of
the continer widget.
Instead of having widget/window/application create a shortcut from a
KeyEvent within their find methods, we'll just pass them a Shortcut
so that the "where to search" logic doesn't need to be duplicated
for different Shortcut types.
It also lets us handle invalid Shortcut rejection at a higher level,
with most things letting the caller be responsible for not searching
for actions with an invalid shortcut.
TabWidgets couldn't be used in GML properly, as the GML creation
routines didn't actually call the necessary functions in the TabWidget
to get a new tab added. This commit fixes that by making the name of the
tab a normal property, the previously introduced "title", which can be
trivially set from GML. Therefore, try_add_widget() loses an argument
(while try_add_tab doesn't, because it newly constructs the widget).
This allows us to get rid of the silly "fixing my widget tree after the
fact" code in Help and will make it super easy to use TabWidget in
future GML. :^)
