The theming system can now control title bar height, title button
size, title stripe color and the title text shadow color.
The implemented theme metrics system could be later extended to LibGUI
to allow themes to change widget padding, border width, etc.
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.
* The parent information is necessary by the Taskbar to be able to
determine a modal window's parent
* Minimize and maximize modal window stacks together
Accessory windows are windows that, when activated, will activate
their parent and bring all other accessory windows of that parent
to the front of the window stack. Accessory windows can only be
active input windows. The accessory window's parent is always the
active window regardless of whether it is also the active input
window.
In order to route input correctly, input is now sent to the active
input window, which can be any accessory window or their parent,
or any regular window.
The a32 bit tells us whether a memory address is 32-bit or not.
We already have this information in Instruction, so just plumb that
around instead of double-caching the bit.
Adds a new highlighting effect to the actively selected row in
ComboBox ListView. ComboBoxEditor can now be controlled with
page up, page down, and the up and down arrow keys. ESC and loss
of focus now cause comboboxes to close. Now activates on mouseup
as well as return.
Adds a new, more restrictive read-only state to TextEditor which
forbids copying, selecting, editor cursors, and context menus.
Provides a unique appearance on focus which accomodates ComboBox
widgets. All TextEditor modes are now accessed by enum and
set_mode() which sets the editor to Editable, ReadOnly or
DisplayOnly. Updates applications still using set_readonly().
By adding a special LauncherType::Application we can still
get meta data for the application, but also know that we should
consider executing that binary as the default action. LaunchServer
will not do this for us, as it should probably not be allowed to
run arbitrary binaries that haven't been registered as handlers.
For now, only the non-standard _SC_NPROCESSORS_CONF and
_SC_NPROCESSORS_ONLN are implemented.
Use them to make ninja pick a better default -j value.
While here, make the ninja package script not fail if
no other port has been built yet.
Finally use Symbol.iterator protocol in language features :) currently
only used in for-of loops and spread expressions, but will have more
uses later (Maps, Sets, Array.from, etc).
Use some template hacks to force GCC to inline more of the instruction
decoding stuff into the UserspaceEmulator main execution loop.
This is my last optimization for today, and we've gone from ~60 seconds
when running "UserspaceEmulator UserspaceEmulator id" to ~8 seconds :^)
Since this code is performance-sensitive, let's have the compiler do
whatever it can to help us with the most important files.
This yields a ~8% speedup.
This implements the following optimizations:
* Rather than clearing a HashTable of selected items and re-populating
it every time the selection rectangle changes, determine the delta
by only examining the items that might be in the area where the
selection may have changed compared to the previous area. Then
only add/remove selection items as needed.
* When painting, only query and paint the items actually visible.
Also, keep a local cache of item information such as calculated
rectangles and selection state, so it doesn't have to be calculated
over and over again.
Changes the shortcut to expand and collapse subtrees from alt to
ctrl+right/left arrows in TreeView. The current shortcuts conflict
with applications that already have navigation controls bound to alt
like file manager.
