// Add some random movement

qreal dx = ::sin (angle) * 10;

The third example refers to the sourcecode from '
Animation Framework Examples/Animated Tiles
'
and
needs also a subdirectory named '
images
' for the PNG-files. Remark: the background JPG-file is absent but
you can download it with the
'qt4-demos' package
- however you can do without it.
This example has to be changed on a large scale because the output from the MOC (Meta-Object Compiler)
is required. Create a new '
main.h
' file, copy all class definitions into this file and delete the definitions in
'
main.cpp
'.
One possible Makefile might look like this:
DEFINES = -DQT_WEBKIT -DQT_NO_DEBUG -DQT_GUI_LIB -DQT_CORE_LIB -DQT_SHARED
CXX := arm-linux-gnueabihf-g++ -march=armv7 -I/usr/include/qt4
LDFLAGS := -l QtCore -l QtGui -l QtDBus -l glib-2.0 -l png12 -l expat -l pcre -l uuid -l z
all: qt
qrc_animatedtiles.cpp: animatedtiles.qrc images/centered.png images/ellipse.png \
images/figure8.png
images/kinetic.png images/random.png images/tile.png
/usr/bin/rcc -name animatedtiles animatedtiles.qrc -o qrc_animatedtiles.cpp
moc_main.cpp: main.h
/usr/bin/moc-qt4 $(DEFINES) -I/usr/include/qt4 main.h -o moc_main.cpp

qt: main.o qrc_animatedtiles.o
$(CXX) -o $@ main.o qrc_animatedtiles.o $(LDFLAGS)
clean:
