Instead of only doing a relayout in the widget you're invalidating,
we now do a recursive top-down relayout so everything gets updated.
This fixes invalid results after updating a preferred size in some
situations with nested layouts.
Normally if a GWidget has the is_greedy_for_hits() flag set, all hit
tests will hit the widget itself instead of its descendants.
Sometimes it may be desirable to override this behavior, and so this
flag now allows you to do that.
This was a workaround to be able to build on case-insensitive file
systems where it might get confused about <string.h> vs <String.h>.
Let's just not support building that way, so String.h can have an
objectively nicer name. :^)
This solves an issue in GScrollableWidget where hiding one of the two
scrollbars needs to trigger a relayout since the other one should grow
into the "shared space" in the bottom right corner.
A GWidget can now override custom_layout() which will be called at any
time we would normally delegate work to the GLayout, e.g on resize
or child visibility changes, size policy changes, etc.
This macro goes at the top of every CObject-derived class like so:
class SomeClass : public CObject {
C_OBJECT(SomeClass)
public:
...
At the moment, all it does is create an override for the class_name() getter
but in the future this will be used to automatically insert member functions
into these classes.
Instead of LibGUI and WindowServer building their own copies of the drawing
and graphics code, let's it in a separate LibDraw library.
This avoids building the code twice, and will encourage better separation
of concerns. :^)
