I have a 2.67 GHz Celeron processor, 1.21 GB of RAM on a x86 Windows XP Professional machine. My understanding is that the Android emulator should start fairly quickly on such a machine, but for me it does not. I have followed all instructions in setting up the IDE, SDKs, JDKs and such and have had some success in staring the emulator quickly but is very particulary. How can I, if possible, fix this problem?
It appears that the Cursor class does not have a "blank" cursor to begin with, so one could define a new "blank" cursor using the Toolkit.createCustomCursor method.
ReplyDeleteHere's one way I've tried which seems to work:
// Transparent 16 x 16 pixel cursor image.
BufferedImage cursorImg = new BufferedImage(16, 16, BufferedImage.TYPE_INT_ARGB);
// Create a new blank cursor.
Cursor blankCursor = Toolkit.getDefaultToolkit().createCustomCursor(
cursorImg, new Point(0, 0), "blank cursor");
// Set the blank cursor to the JFrame.
mainJFrame.getContentPane().setCursor(blankCursor);
Edit
Regarding the comment about everything inside the JFrame ending up without a cursor, it seems that the Components which are contained in the JFrame will end up inheriting the cursor of the container (the JFrame), so if it is a requirement to have a certain Component have the cursor appear, one would have to manually set the desired cursor.
For example, if there is a JPanel contained in the JFrame, then one could set the cursor of that JPanel to the system's default using the Cursor.getDefaultCursor method:
JPanel p = ...
// Sets the JPanel's cursor to the system default.
p.setCursor(Cursor.getDefaultCursor());
frame.setCursor(frame.getToolkit().createCustomCursor(
ReplyDeletenew BufferedImage(3, 3, BufferedImage.TYPE_INT_ARGB), new Point(0, 0),
"null"));
When using the LWJGL under Mac OS you need to do this:
ReplyDeleteSystem.setProperty("apple.awt.fullscreenhidecursor","true");
I solve this problem much easier:
ReplyDeletefinal Timer cursorTimer = new Timer(2000, new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
getContentPane().setCursor(null);
}
});
cursorTimer.start();
addMouseMotionListener(new MouseMotionAdapter() {
@Override
public void mouseMoved(MouseEvent e) {
getGlassPane().setCursor(Cursor.getDefaultCursor());
cursorTimer.restart();
}
});
