This fixes a weird dependency graph in DisplaySettings. The widget itself
(which is described in `gml` now), no longer contains `root_widget()`.
The widget itself has been moved into a tabbed pane, to get it ready
to add some more features and bring it more up to date with the current
UI code.
Instead of hard-coding 22 in random places, just make the following
widgets have a fixed height of 22 by default: Button, CheckBox,
ColorInput, ComboBox, RadioButton, SpinBox, TextBox.
In the future we can make this relative to the current font size,
but for now at least this centralizes the setting a bit better.
This patch removes size policies and preferred sizes, and replaces them
with min-size and max-size for each widget.
Box layout now works in 3 passes:
1) Set all items (widgets/spacers) to their min-size
2) Distribute remaining space evenly, respecting max-size
3) Place widgets one after the other, adding spacing in between
I've also added convenience helpers for setting a fixed size (which is
the same as setting min-size and max-size to the same value.)
This significantly reduces the verbosity of widget layout and makes GML
a bit more pleasant to write, too. :^)
New serenity_app() targets can be defined which allows application
icons to be emedded directly into the executable. The embedded
icons will then be used when creating an icon for that file in
LibGUI.
If loading the WindowServer config fails or we get a value other than
"simple", "center", "tile", or "scaled", DisplaySettings would crash
when changing the wallpaper image.
Fixes#4360.
Currently, every time the wallpaper picker changes, an additional
attempted file load happens on top of the file load to create the
bitmap. The only values that the wallpaper picker can take on are
filenames that can never be valid when loaded without the /res/wallpaper
prefix. To reduce the amount of log spam and speed up wallpaper picking,
this patch only attempts to load wallpapers with slash-prefixed names,
assumed to be the absolute path to that wallpaper. Additional wallpapers
outside of /res/wallpapers/ should still be accessible with this patch,
and the experience is improved for the more common case of selecting a
built-in wallpaper.
Since the vast majority of message boxes should be modal, require
the parent window to be passed in, which can be nullptr for the
rare case that they don't. By it being the first argument, the
default arguments also don't need to be explicitly stated in most
cases, and it encourages passing in a parent window handle.
Fix up several message boxes that should have been modal.
During app teardown, the Application object may be destroyed before
something else, and so having Application::the() return a reference was
obscuring the truth about its lifetime.
This patch makes the API more honest by returning a pointer. While
this makes call sites look a bit more sketchy, do note that the global
Application pointer only becomes null during app teardown.
Ideally, we would copy the file to `/res/wallpapers`, add an entry to
`ComboBox` model and set the index to this entry. I didn't want to
touch anything outside of `DisplaySettings`, so this is more of a
workaround :^)
Get rid of the weird old signature:
- int StringType::to_int(bool& ok) const
And replace it with sensible new signature:
- Optional<int> StringType::to_int() const
Running 'pape' without arguments (or just editing the WindowServer.ini by hand)
can confuse DisplaySettings. Specifically, if the 'Wallpaper' is set to
'/res/wallpapers/', then DisplaySettings used to crash because 'name_parts'
wouldn't contain any trailing element.
It's hard to define desired behavior, but this is better than crashing
and confusing the user.
