Columns can now be best-fit resized by double-clicking their
grabbable edges. When a default width is set and all data is empty,
double-clicking will restore the column to its original state.
With a little help (read: copy & paste) from ImageWidget, QuickShow will
now cycle through the frames of animated images - enjoy the cat GIFs!
Future improvement: cache decoded images like LibWeb's ImageResource to
waste less CPU - the same applies to LibGUI though, maybe we can put
something shared in LibGfx.
Closes#5837.
The image decoder already tells us whether the image is animated and it
can provide more than one frame, let's not put this behind an artificial
"file path must end with lowercase .gif" barrier.
This was a kludge to paint ComboBox editors before the advent of
accessory windows, isn't being used anymore, and was inadvertently
letting two ComboBoxes paint as if both had focus.
The previous names (RGBA32 and RGB32) were misleading since that's not
the actual byte order in memory. The new names reflect exactly how the
color values get laid out in bitmap data.
Prevents discrete values from being skipped when using the mouse
wheel on SpinBoxes and proportional Sliders. Wheel delta can be
accelerated by holding Ctrl.
If we set selection before the IconView is laid out, it has no size.
So it can't correctly calculate where to scroll. Forcing scroll after
the first resize fixes that.
This makes drawing text with spans a lot faster.
The previous implentation went character by character and then
checked every span whether it contained the current character.
This implentation asumes that the spans are sorted and goes span by
span drawing all the characters contained at once.
Any spans that are out of order will be ignored!
Note: text wrapping is not (yet) supported
The Locator now keeps a cache of the declared symbol in a document.
The language client updates that cache whenever it gets an update from
the language server about declared symbols.
This allows searching for symbol declarations in the Locator, in
addition to file names.
Closes#5478
Having TextRange which is empty doesn't make any sense. So it confuses
the functions that rely on having valid range, and causes them to do
no action.
Fixes#5341
This patch provides the basic components needed for developers to create
consistent wizard interface experiences in their applications.
`WizardDialog` provides the dialog frame for the wizard, handling navigation
and presentation.
`AbstractWizardPage`s form the base class of Wizard pages, which are
pushed onto the `WizardDialog` page stack via `WizardDialog::push_page`.
`CoverWizardPage` and `WizardPage` are provided to ease the creation of
Wizard interfaces consistent with the Serenity visual language.
This is basically just for consistency, it's quite strange to see
multiple AK container types next to each other, some with and some
without the namespace prefix - we're 'using AK::Foo;' a lot and should
leverage that. :^)
Rather than invalidating the entire window, which is very expensive on
the transparent desktop widget, just invalidate the areas that actually
need updating.
It's possible that pending invalidation rectangles haven't been
flushed when processing a paint event. Handle them right away,
which avoids another round trip.
In line wrapping mode, the same column refers both to the end of a
visual line and the beginning of the subsequent visual line. This
meant that the cursor couldn't move to the beginning of a visual
line. Now, we only let the cursor go to the end of a physical line,
not the visual line.
Closes#4786
(...and ASSERT_NOT_REACHED => VERIFY_NOT_REACHED)
Since all of these checks are done in release builds as well,
let's rename them to VERIFY to prevent confusion, as everyone is
used to assertions being compiled out in release.
We can introduce a new ASSERT macro that is specifically for debug
checks, but I'm doing this wholesale conversion first since we've
accumulated thousands of these already, and it's not immediately
obvious which ones are suitable for ASSERT.
