Propagate the want of an alpha channel as attribute of Framebuffer::Mode
instead of passing this property as a separate bool argument.
This clears the way for adding useful accessors for pixel/alpha/input
surfaces to the Mode type as a subsequent step.
Issue #5351
This patch moves the management of view IDs from the server to the
client side. The former 'create_view' and 'create_child_view'
operations do no longer return a view ID but take a view ID as
argument. While changing those operations, this patch takes the
opportunity to allow for initial view attributes. Combined, those
changes simplify the window manager while accommodating typical
client use cases with less code.
To ease the client-side ID management, the Gui::Connection hosts
a 'view_ids' ID space for optional use. E.g., the new 'Top_level_view'
class uses this ID space for ID allocation. This class accommodates the
most typical use case of opening a single window.
The 'alloc_view_id' RPC function is no longer needed.
Issue #5242
This patch eliminates the use of invalid view handles as special
Session::Command arguments. The TO_FRONT and TO_BACK operations
interpreted as invalid neighbor as top-most or back-most position.
Those corner cases are now expressed via dedicated commands. The
new stacking commands are FRONT, BACK, FRONT_OF, and BEHIND_OF.
While changing the command interface, the patch removes the OP_
prefix from the opcode values.
Issue #5242
- Rename framebuffer_session to framebuffer and
input_session to input as those RPC interfaces are no longer
meant to be used as stand-alone sessions.
- Host Connection::input and Connection::framebuffer as public
members, thereby removing the use of pointers. This simplifies
the client-sized code. E.g., '_gui.input()->pending()' becomes
'_gui.input.pending()'.
Issue #5242
- Move header to base/include to make it applicable for base types
like 'Affinity' down the road.
- Represent 'Rect' as typle of point and area, which is the most
common form of initialization, creates in valid 'Rect' by default.
- Turn Point, Area, and Rect into compound types, making x, y, w, h, at,
area accessible without a method call
- 'Rect::Compound' function for constructing a 'Rect' from two points,
replacing a former constructor
- Use result type 'Rect::Cut_remainder' instead of out parameters.
Fixes#5239
Until now, Genode's framebuffer session interface was based on the
RGB565 pixel format. This patch changes the pixel format to 32-bit
XRGB where the X part is ignored. It adapts all graphical applications
and device drivers accordingly.
The patch also adjusts the users of the drivers_interactive packages,
assigning 64 MiB RAM and 1500 caps to the drivers subsystem, which is
sufficient for covering high resolutions at 32 bits per pixel and to
accommodate multi-component USB HID input stacks.
Fixes#3784
