Remove obsolete w32-qt code
* configure.ac (w32-qt): Remove option and Qt checks. * src/Makefile.am: Remove BUILD_W32_QT handling. * src/kdpipeiodevice.cpp, src/kdpipeiodevice.h, src/kdpipeiodevice.moc, src/w32-qt-io.cpp: Removed. -- This code was intended for Kleopatra but Kleopatra is not using it anymore. QGpgme/dataprovider is a better replacement for this.

/* This file is an ugly hack to get GPGME working with Qt on Windows
|
|
||||||
targets. On Windows, you can not select() on file descriptors.
|
|
||||||
|
|
||||||
The only way to check if there is something to read is to read
|
|
||||||
something. This means that GPGME can not let Qt check for data
|
|
||||||
without letting Qt also handle the data on Windows targets.
|
|
||||||
|
|
||||||
The ugly consequence is that we need to work on QIODevices in
|
|
||||||
GPGME, creating a Qt dependency. Also, we need to export an
|
|
||||||
interface for the application to get at GPGME's QIODevices. There
|
|
||||||
is no good way to abstract all this with callbacks, because the
|
|
||||||
whole thing is also interconnected with the creation of pipes and
|
|
||||||
child processes.
|
|
||||||
|
|
||||||
The following rule applies only to this I/O backend:
|
|
||||||
|
|
||||||
* ALL operations must use the user defined event loop. GPGME can
|
|
||||||
not anymore provide its own event loop. This is mostly a sanity
|
|
||||||
requirement: Although we have in theory all information we need to
|
|
||||||
make the GPGME W32 code for select still work, it would be a big
|
|
||||||
complication and require changes throughout GPGME.
|
|
||||||
|
|
||||||
Eventually, we probably have to bite the bullet and make some
|
|
||||||
really nice callback interfaces to let the user control all this at
|
|
||||||
a per-context level. */
