Take into account the current scroll position when calculating the
position of cells. This way when the user scrolls either horizontally
or vertically, the calculations done to find the cell position
will be correct.
Day and month name constants are defined in numerous places. This
pulls them together into a single place and eliminates the
duplication. It also ensures they are `constexpr`.
`static const` variables can be computed and initialized at run-time
during initialization or the first time a function is called. Change
them to `static constexpr` to ensure they are computed at
compile-time.
This allows some removal of `strlen` because the length of the
`StringView` can be used which is pre-computed at compile-time.
This patch makes background a bit darkened so that it is possible to
distinguish out of range area from glyphs that are just not drawn.
The default background color is also changed to Window so that it looks
good in more themes.
Previously, when double clicking on the tab bar, all tabs would respond
to the double click even if they weren't clicked on.
This issue, for example, prevented renaming of individual tabs in
Spreadsheet and instead asked the user to rename all tabs one by one.
Previously using the highlighted_search would not set the cursor
to the item found by the search. This results in some unfamiliar
behavior such as jumping back up to the previously selected element,
before searching, when using the arrow keys to navigate.
Crash was caused by deferred invocation of a lambda on the SpinBox's
TextEditor widget's on_change. The lambda referenced the SpinBox ptr,
but in GML Playground the SpinBox was free'd before the deferred
lambda could run, causing a use-after-free error. Fixed by using
a weak ptr to detect if the SpinBox was free'd.
Currently, disabled text colors are hardcoded. They look good in Default
and light themes, but no so good in dark ones. This PR adds new
variables for all themes to correctly display disabled text.
This matches the rename of RGBA32 to ARGB32. It also makes more sense
when you see it used with 32-bit hexadecimal literals:
Before:
Color::from_rgba(0xaarrggbb)
After:
Color::from_argb(0xaarrggbb)
The ARGB32 typedef is used for 32-bit #AARRGGBB quadruplets. As such,
the name RGBA32 was misleading, so let's call it ARGB32 instead.
Since endianness is a thing, let's not encode any assumptions about byte
order in the name of this type. ARGB32 is basically a "machine word"
of color.
`CharacterBitmap` instances are generated at run-time and put on the
heap, but they can be created in a `constexpr` context and stored in
static memory.
Also, remove additional `width` and `height` `static` values in favor
of using the `constexpr` member functions of `CharacterBitmap`.
These changes also include the removal of some initialization code
which tests if the `CharacterBitmap` is created since it is always
created and removes function-local `static` values which cause
run-time branches to ensure it is initialized each time the function
is called.
A button that is "mimic pressed" is drawn like it is being clicked when
it isn't necessarily actually being pressed. This lets programs which
keyboard based input that mirrors a button to show visual feedback when
a key is pressed.
The last commit fixes a bug, but also exposes the fact that trailing
space highlighting isn't really supported on multiple lines. This patch
correct the wrong behavior by adding an offset to adjust rectangle's
position.
Before this patch the highlighted rectangle wasn't placed on the right
spot. Now the red highlighting is correctly placed at the end of the
line. This was due to a function called with a wrong argument.
This shape is for use by the main widget of a frameless window
that still wishes to have proper borders but no title.
Raised Containers were used previously for this pattern but did not
always represent perspective and shadow correctly depending on thread
highlighting and the immediate background color. Containers are
really meant to be used inside other widgets where the background
color can be controlled.
This adds a keyboard event for Super+0 to Super+9. Later to be consumed
in the taskbar.
Currently only this keyboard sequence is supported:
- Super key down
- Digit key down
But not this:
- Super key down
- Digit key down
- Digit key up
- Digit key down
Segments inherit from Button and let us add clickable widgets
to status bars. This patch also adds proportional, fixed and
autosized modes for segments and lets the status bar consume
all non-clickable segments for override text.
Fonts now provide their preferred line height based on maximum
height and requested line gap. TTFs provide a preferred line gap
from table metrics while BitmapFonts are hardcoded at the previous
default for now.
Ruler needs to take into account spacing between glyphs for
proportional fonts as line count increases. This also replaces
the less accurate 'x' width estimate for widest character with
a '4'
These will require some tweaking here and elsewhere in LibGUI, to handle
both rendering of the emojis as single glyphs consistently, and faking
key events with multiple code points after selecting one.
This necessitates switching from passing a single code point to the
callback to passing a non-const Utf8CodePointIterator instead.
Note that the text selection mechanisms in LibGUI and LibWeb don't
handle this properly yet; they still assume that each code point
renders as one glyph. Similarly, width calculations for text widths
don't either, so a single such an emoji will require space for more
than one glyph.
It also doesn't work in LibVT's TerminalWidget, where each code point
is handled and rendered separately, so LibGfx never gets a chance to
check if subsequent code points could result in a combined emoji.
Different thread highlights between widgets lead to different
visual weights between splitters, even when they have the same
width or height. This means some splitters look best at odd
sizes while others even. This sets the default spacing to the
most commonly used, depending on orientation, and adjusts
spacing for a few apps based on the new paint rect.
The most consistent look across apps requires some manual
tweaking occassionally. Knurlheads, use your discretion!
Splitters could be resized in such an order that all their remaining
children were fixed size, leading to unfillable gaps on resize events.
HackStudio and TextEditor already had logic to handle this edge case,
so this patch factors it into a general solution for all Splitters.
At least one widget is now guaranteed to be resizeable after a child
is removed.
