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.
Add all 6 shortcuts even if the switch between VirtualConsoles is
currently not available in the graphical console.
Also make the case statement more compact.
It is possible to switch to VirtualConsoles 1 to 4 via the shortcut
ALT + [1-4]. Therefor the array of VirtualConsoles should be guaranteed
to be initialized.
Also add an constant for the maximum number of VirtualConsoles to
guarantee consistency.
When walking the modal window stack upwards, we need to check if
the top modal window is still a descendant of the window that
the parent is blocked by. Fixes not all windows being brought to
the front when trying to active a parent in the middle of the
modal window stack.
When catching a use-after-free, we now also print out the backtraces
for where the memory was allocated, and for where it was freed.
This will be extremely helpful for debugging.
Upon exit, the emulator will now print a leak report of any malloc
allocations that are still live and don't have pointers to their base
address anywhere in either another live mallocation, or in one of the
non-malloc-block memory regions.
Note that the malloc-block memory region check is not fully functional
and this will work even better once we get that fixed.
This is pretty cool. :^)
It's useful with the newly added for loops in Shell.
SerenityOS's printf() doesn't seem to print decimals for
doubles correctly, so this doesn't print the right output for
fractional numbers yet.
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
Closes#2760.
This commit adds a 'for' loop, and tweaks the syntax slightly to make &&
bind more tightly than || (allowing for `expr && if_ok || if_bad`) :^)
This fixes a few problems with modal windows:
* If any child window, or any child window further down the
tree is considered modal, then all windows in that chain
are modal.
* When trying to activate a window blocked by a modal child
bring the entire stack of modal windows to the front and
activate the modal window.
* A window is modal if it has a parent and it's flagged as
modal, regardless of whether the ClientConnection has
created modal windows.
This technically supports diverging modal window trees as well,
where two modal windows share the same parent, allowing both to
be activated (including for input) but not the parent. And it
should also support modal window stacks of arbitrary depth.
