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. :^)
This is mostly based on TextDocument's similar methods, these will
help implement searching within the terminal application.
The support for unicode code points is shaky at best, and should
probably be improved further.
This was mentioned in #4574, and the more I think about it the more it
feels just right - let's move it there! :^)
Having to link LaunchServer against LibGUI explicitly should've been
telling enough...
Similar to "Copy URL" there is now a "Copy name" action in the context
menu specialized for terminal links. I chose to not alter the behaviour
of the existing copy action to prevent surprises when text is selected
and the user happens to place the cursor over a link.
Closes#4187.
The copy action is now only enabled if there is a selection.
The paste action is now only enabled if the clipboard contains something
the terminal considers pasteable - that is, non-empty data with a text/*
MIME-type. Previously we'd happily paste things like bitmaps into the
terminal, causing it to blow up.
TerminalWidget will now automatically scroll up or down when the user
drags the mouse out of its bounds while selecting text. This happens
at a fixed speed.
Every widget now has a GUI::FocusPolicy that determines how it can
receive focus:
- NoFocus: The widget is not focusable (default)
- TabFocus: The widget can be focused using the tab key.
- ClickFocus: The widget can be focused by clicking on it.
- StrongFocus: Both of the above.
For widgets that have a focus proxy, getting/setting the focus policy
will affect the proxy instead.
The qualified name of a font is "<Family> <Size> <Weight>". You can
get the QN of a Font via the Font::qualified_name() API, and you can
get any system font by QN from the GUI::FontDatabase. :^)
This patch adds GUI::FocusEvent which has a GUI::FocusSource.
The focus source is one of three things:
- Programmatic
- Mouse
- Keyboard
This allows receivers of focus events to implement different behaviors
depending on how they receive/lose focus.
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.
You can now request an update of the terminal's window progress by
sending this escape sequence:
<esc>]9;<value>;<max_value>;<escape><backslash>
I'm sure we can find many interesting uses for this! :^)
And move canonicalized_path() to a static method on LexicalPath.
This is to make it clear that FileSystemPath/canonicalized_path() only
perform *lexical* canonicalization.
To conserve memory, we now use byte storage for terminal lines until we
encounter a non-ASCII codepoint. At that point, we transparently switch
to UTF-32 storage for that one line.
