This also adds an API to Label to determine if the Label itself or its
child TextNode is hovered. This allows ButtonBox to render in a hovered
state when the label is hovered.
They are the same as strtol() and strtoul() but if there is
overflow/underflow then the maximum integer val/lower integer
val/maximum uint val will be returned while also setting errno to
ERANGE.
A label's format is: <label>Label text</label>
So, a TextNode is created as a child of the Label node, and EventHandler
will send events to the TextNode. This changes TextNode to accept mouse
events if its parent is a Label, and to forward those events upward.
The HTML <label> element is special in that it may be associated with
some other <input> element. When the label element is clicked, the input
element should be activated.
To achieve this, a LableableNode base class is introduced to provide an
interface for "labelable" elements to handle mouse events on their
associated labels. This not only allows clicking the label to activate
the input, but dragging the mouse from the label to the input (and vice-
versa) while the mouse is clicked will also active the label.
As of this commit, this infrastructure is not hooked up to any elements.
For example:
<div>
<input type=radio name=group value=item1 />
</div>
<div>
<input type=radio name=group value=item2 />
</div>
Is a valid DOM and clicking on of these radio buttons should uncheck
the other.
Previously, `vsscanf()` would crash whenever it encountered a width
specification. Now, it consumes the width specification but does not
yet do anything with it.
...for 'long long' and 'unsigned long long', instead of reading them as
'long's and 'unsigned long's.
Also add a test for values that can only fit in (unsigned) long long.
Fixes#6096.
Having to rely on GUI::Desktop's on_rect_change is quite limiting and a
bit awkward (continuing to use it would mean having to setup the
callback in every application using a webview) - we need a better way of
letting widgets know of a screen rect change automatically.
The specific use case will be IPWV/OOPWV which need to keep track of the
screen rect and notify the WebContent service of any change (which on
its own deliberately can't interact with WindowServer at all).
It'll also be useful for notification windows and the taskbar, which
currently both rely on the GUI::Desktop callback but will now be able to
listen and react to the event themselves.
This was a regression from the 64-bit off_t changes.
When dropping buffered data after a flush, we would subtract the
buffered amount from zero to get the seek offset. This didn't work
right since the subtraction was done with a 32-bit size_t and we
ended up with e.g (i64)0xfffffffc as the offset.
Fixes#6003.
Now the kernel supports 2 ECAM access methods.
MMIOAccess was renamed to WindowedMMIOAccess and is what we had until
now - each device that is detected on boot is assigned to a
memory-mapped window, so IO operations on multiple devices can occur
simultaneously due to creating multiple virtual mappings, hence the name
is a memory-mapped window.
This commit adds a new class called MMIOAccess (not to be confused with
the old MMIOAccess class). This class creates one memory-mapped window.
On each IO operation on a configuration space of a device, it maps the
requested PCI bus region to that window. Therefore it holds a SpinLock
during the operation to ensure that no other PCI bus region was mapped
during the call.
A user can choose to either use PCI ECAM with memory-mapped window
for each device, or for an entire bus. By default, the kernel prefers to
map the entire PCI bus region.
