Since all reference-captured variables where pointers to non-stack
objects whose owners outlive the lambdas, things were fine in practice,
but it's a bit brittle and it makes a change I want to make in this code
more difficult.
Various applications were using the same slightly verbose code to center
themselves on the screen/desktop:
Gfx::IntRect window_rect { 0, 0, width, height };
window_rect.center_within(GUI::Desktop::the().rect());
window->set_rect(window_rect);
Which now becomes:
window->resize(width, height);
window->center_on_screen();
This commit adds a new GUI widget type, called CodeDocument, which
is a TextDocument that can additionaly store data related to the
debugger.
This fixes various bugs and crashes that occured when we switched
between files in debug mode, because we previously held stale breakpoint
data for the previous file in the Editor object.
We now keep this data at the "document" level rather than the Editor
level, which fixes things.
Application::show_tooltip() now keeps track of the application's active
tooltip source widget so it can be updated while being shown when the
same widget updates its tooltip label.
Application::hide_tooltip() will unset the tooltip source widget,
respectively.
This is pretty useful for the ResourceGraph applet's tooltips!
Also re-use the Application::TooltipWindow's rect position in its
set_tooltip() method to avoid flickering from the window temporarily
being moved to 100, 100 and the position adjusted moments later.
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.
Using a command-line argument for this clashed with ArgsParser so let's
use an environment variable instead. I feel like Sergey told me to do
this at some point anyway. :^)
This was using window()->position(), which is unset for windows with
WindowType::MenuApplet. Now it checks the window type and then uses
rect_in_menubar() for MenuApplet windows and rect() for everything else.
This makes tooltips show up for MenuApplet windows, previously they were
positioned off-screen :^)
Previously the ColorPicker would get the custom color directly from the
window, this was changed in d7d5788469 to
get the color from the underlying bitmap instead - without taking the
bitmap's scaling into effect though, so resulting colors were off by
quite a bit.
Fixes#3113.
Subtracting 128 from the desktop rect's height was far to much and
and leading to weird rendering issues - now it's calculated exactly from
taskbar and menubar heights as well as a little additional offset to
make it fit perfectly.
Fixes#3115.
Instead of setting m_cursor directly to reset the cursor position,
TextEditor::set_document() now uses set_cursor() which will call cursor
change callback functions, if any.
This fixes a bug in HackStudio where the cursor information text would
not update immediately after changing the active TextDocument, even
though the cursor is always visibly being reset to 0, 0.
This prevents windows from being opened directly on top of eachother,
and provides default behavior for when window position is not specified.
The new behavior is as follows:
- Windows that have been created without a set position are assigned one
by WindowServer.
- The assigned position is either offset from the last window that is
still in an assigned position, or a default position if no such window
is available.
It doesn't make sense for a top-level menu to have an icon, however
we do not have dedicated classes to distinguish these.
Furthermore, the only other place to store an icon is MenuItem.
Storing it there would be highly confusing, as MenuItem-with-Action
then would have two icons: one in Action and one in MenuItem.
And because we need to be able to replace the icon during realization,
this would need to write-through to Action somehow.
That's why I went with Menu, not MenuItem.
This factors out icon realization into its own function, making it possible to
use the same code with other classes that have icon() and set_icon() methods.
Moves ProcessChooser and RunningProcessesModel to LibGUI and
generalizes their construction for use by other apps. Updates
Profiler to reflect the change and use its new icons.
\x consumes all hex digits following it. (If the resulting number
then doesn't fit in the character type, the compiler emits an
error.)
\x would be much more convenient to use if it was always followed
by exactly two hex digits (with \u and \U for higher codepoints),
but that's sadly not the world we live in.
