This change makes it possible to reuse the generic window decorator
classes in include/decorator/ for decorators of a different structure.
E.g., instead of painting decorations on a single nitpicker session,
each window may paint its decorations into additional window-specific
nitpicker sessions.
For each session upgrade performed by a wm client as part of the
Nitpicker::Connection::buffer function, the window manager wrongly
upgraded the wrapped nitpicker session twice: Once by handling the
Root::upgrade, and again by handling of the server-side 'buffer'
operation. Here, the 'buffer' operation was implemented by not merely
forwarding the RPC request to the wrapped nitpicker session but by
calling the 'buffer' method on the wrapped session's connection
object, which implictly issues session upgrades. Consequently,
the window manager would transfer twice the amount of the session
upgrades it received by its clients to nitpicker and eventually ran
out of memory.
The patch fixes the problem by eliminating the call of the
Nitpicker::Connection::buffer method and instead merely forward the RPC
requests to the wrapped nitpicker sessions.
This patch, complements the existing vbox layout with a hbox layout and
improves the response to dynamic dialog updates. The new version support
disappearing widgets and the reordering of widgets. Furthermore, this
patch ensures that the 'Widget::_layout' functions are executed after
updating a new version of the dialog.
This patch improves the decorator in two ways. First, it enables the
assignment of window colors depending on the window labels. This
configuration can be changed dynamically. Second, it adds the handling
of window controls for closing, maximizing, minimizing windows.
Issue #1689Fixes#1688
Until now, the CLI monitor and the laucher allowed the user to explitly
kill subsystems but both used to ignore gracefully exiting subsystems.
It was the user's job to remove the remains of those subsystems. The
patch takes the burden of manually killing exited subsystems from the
user.
Fixes#1685
If a client provides a read buffer of insufficient size for all
available data, we have two options
1) Leave it to the client to do partial reads until not further data is
available, or
2) Signal the client that there still some bytes on a partial read.
As the second option seems more robust it's implemented in this commit.
Fixes#1705
Instead of returning pointers to locked objects via a lookup function,
the new object pool implementation restricts object access to
functors resp. lambda expressions that are applied to the objects
within the pool itself.
Fix#884Fix#1658
This patch changes the window manager, the decorator, and the
floating window layouter to propagate the usage of an alpha channel from
the client application to the decorator. This way, the decorator can
paint the decoration elements behind the affected windows, which would
otherwise be skipped.
This patch adds two new painters located at gems/include/polygon_gfx.
Both painters draw convex polygons with an arbirary number of points.
The shaded-polygon painter interpolates the color and alpha values
whereas the textured-polygon painter applies a texture to the polygon.
The painters are accompanied by simplistic 3D routines located at
gems/include/nano3d/ and a corresponding example (gems/run/nano3d.run).
The menu view generates a simple dialog of widgets and reports the
hovered element. It is meant to be embedded into applications that
require simple GUIs but don't want to deal with the pecularities of
a full-blown widget set.
If the Rom_session::update function returns false, the ROM dataspace may
have been physically destructed (and core has removed all mappings).
In this case, we have to omit the detach operation in the destructor
of 'Attached_dataspace' to avoid detaching the same region twice.
The headers 'texture_rgb565.h' and 'texture_rgb888' contain
template specializations needed for using the 'Texture::rgba' function
for the respective pixel formats. The specializations were formerly
contained in application-local code.
