Hi,
The only way I can think of to do what you want is with an approach like
below. It's not pretty but it seems to work.
static Runnable runnable = null;
static int INTERVAL = 99;
public static void main(String[] args) {
final Display display = new Display();
final Shell shell = new Shell(display, SWT.TOOL);
shell.setLayout(new GridLayout());
final Text text = new Text(shell, SWT.MULTI | SWT.READ_ONLY | SWT.WRAP |
SWT.V_SCROLL);
text.setLayoutData(new GridData(200,200));
text.addListener(SWT.MouseExit, new Listener() {
public void handleEvent(Event event) {
if (display.getCursorControl() != text) {
System.out.println("exited via edge without scrollbar, so
hide it now");
} else {
runnable = new Runnable() {
public void run() {
if (text.isDisposed()) return;
if (display.getCursorControl() != text) {
System.out.println("exited scrollbar, so hide it
now");
} else {
display.timerExec(INTERVAL, this);
}
}
};
display.timerExec(INTERVAL, runnable);
}
}
});
text.addListener(SWT.MouseEnter, new Listener() {
public void handleEvent(Event event) {
if (runnable != null) {
display.timerExec(-1, runnable);
}
}
});
shell.pack();
shell.open();
while (!shell.isDisposed()) {
if (!display.readAndDispatch()) display.sleep();
}
display.dispose();
}
HTH,
