\class QPlatformScreenPageFlipper
93
\brief The QPlatformScreenPageFlipper class provides an abstract interface for display buffer swapping
95
Implement the displayBuffer() function to initiate a buffer swap. The
96
bufferDisplayed() signal should be emitted once the buffer is actually displayed on
97
the screen. The bufferReleased() signal should be emitted when the buffer data is no
98
longer owned by the display hardware.
101
QPlatformScreenPageFlipper::QPlatformScreenPageFlipper(QObject *parent)
108
\fn bool QPlatformScreenPageFlipper::displayBuffer(QPlatformScreenBuffer *buffer)
110
Implemented in subclasses to display \a buffer directly on the screen. Returns \c true
111
if it is possible to display the buffer, and \c false if the buffer cannot be displayed.
113
If this function returns true, the buffer must not be modified or destroyed before the
114
bufferReleased() signal is emitted. The signal bufferDisplayed() is emitted when the buffer
115
is displayed on the screen. The two signals may be emitted in either order.
117
This function is allowed to block.
