This patch removes the 'Framebuffer::Session::release()' function from
the interface to make the mode-change protocol consistent with the way
the Rom_session interface handles ROM-module changes. That is, the
client acknowledges the release of its current dataspace by requesting a
new dataspace via the 'Framebuffer::Session::dataspace()' function.
Fixes#1057
This patch changes the interface of Nitpicker to support dynamically
dimensioned virtual frame buffers. This solves two problems:
First, it enables a client to create a connection to nitpicker without
donating much session quota in advance. The old interface required each
screen-size-dependent client to donate as much memory as needed to
allocate a screen-sized virtual framebuffer. For clients that are
interested int the screen size but cover just a small portion of the
screen (e.g., a banner, a menu, an applet that sits in the screen
corner), this overprovisioning is painful. The new interface allows such
clients to upgrade the session quota for an existing session as needed.
Second, because each nitpicker session used to have a virtual frame
buffer with a fixed size over the lifetime of the session, a client that
wanted to implement a variable-sized window had to either vastly
overprovide resources (by opening a session as large as the screen just
in order to be prepared for the worst case of a maximized window), or it
had to replace the session by a new one (thereby discarding the stacking
order of the old views) each time the window changes its dimensions. The
new interface accommodates such clients much better.
Originally, the convenience utility for accessing a process
configuration came in the form of a header file. But this causes
aliasing problems if multiple compilation units access the config while
the configuration gets dynamically updated. Moving the implementation of
the accessor to the singleton object into a library solves those
problems.
This patch implements a simple Qt-based media player which is actually a
graphical user interface for the SDL-based 'avplay' media player from
'libav'. It starts 'avplay' as a child and shows its graphical output in a
'QNitpickerViewWidget'. The widgets for controlling the player state send
the according keyboard and mouse input events to 'avplay'.
The 'qt_avplay' player supports the following configuration options:
<mediafile name="..."/>
-> name of the media file to play
<framebuffer_filter name="..." ram_quota="..."/> (may appear multiple times)
-> name of a framebuffer filter service to filter the video output
Fixes#222.
- Remove example application source code files which also exist in contrib
- Outsource commonly used parts from target.mk files
- Store the current Qt version only in one place
- Add run scripts for the example applications
Fixes#127.
