Commit c5db8fc74 changed all instances of Q_WS_FOO to have the prefix
Q_DEAD_CODE_FROM_QT4 instead, to make it clearer when reading the code
that the code in question was a left-over from Qt4, when we used
Q_WS_ defines instead of Q_OS_ defines.
This worked well for cases of #ifdef Q_DEAD_CODE_FROM_QT4, but less so
for cases of #ifndef Q_DEAD_CODE_FROM_QT4, where the code was actually
unconditionally included.
To make this even clearer, the defines have been replaced by checks for
1 or 0, with a comment describing how the code used to look in Qt4. The
use of constants in the check also makes it easier for editors to parse
the condition and show visually that the code is defined out.

swapInThread
|
|
|
|
The purpose of this testcase is to verify that it is possible to do rendering into
|
|
a GL context from the GUI thread, then swap the contents in from a background thread.
|
|
|
|
The usecase for this is to have the background thread do the waiting for vertical
|
|
sync while the GUI thread is idle.
|
|
|
|
Currently the locking is handled directly in the paintEvent(). For the actual usecase
|
|
in Qt, the locking is done in the windowsurface before starting any drawing while
|
|
unlocking is done after all drawing has been done.
