Execute the following code: Shell shell = new Shell(SWT.MENU | SWT.RESIZE | SWT.TITLE | SWT.V_SCROLL | SWT.H_SCROLL); ScrollBar hbar = shell.getHorizontalBar(); ScrollBar vbar = shell.getVerticalBar(); hbar.setMaximum(0); System.out.println("hbar.getMaximum() " + hbar.getMaximum()); hbar.setVisible(false); // comment out this line and vbar.setMaximum works vbar.setMaximum(0); // this call has no effect System.out.println("vbar.getMaximum() " + vbar.getMaximum()); vbar.setMaximum(0); // second call works System.out.println("vbar.getMaximum() " + vbar.getMaximum()); The first call to vbar.setMaximum(0) has no effect unless the horizontal scroll bar is visible. NOTES: McQ (29/11/2000 10:10:36 AM) - Not sure what's going on here. If it's an o/s limitation, you're probably just stuck. If it's something we are doing wrong, then we should fix it. SN to investigate.

No longer appears to be happening. KR, can you confirm? Here is the code that I'm using: package steve; import org.eclipse.swt.*; import org.eclipse.swt.widgets.*; public class PR_4462 { public static void main(String arguments[]) { Shell shell = new Shell(SWT.MENU | SWT.RESIZE | SWT.TITLE | SWT.V_SCROLL | SWT.H_SCROLL); ScrollBar hbar = shell.getHorizontalBar(); ScrollBar vbar = shell.getVerticalBar(); hbar.setMaximum(25); System.out.println("hbar.getMaximum() " + hbar.getMaximum()); hbar.setVisible(false); // comment out this line and vbar.setMaximum works vbar.setMaximum(50); // this call has no effect System.out.println("vbar.getMaximum() " + vbar.getMaximum()); vbar.setMaximum(33); // second call works System.out.println("vbar.getMaximum() " + vbar.getMaximum()); } }
