Hi anonymous,
The IJ.showMessageWithCancel method is a GenericDialog, like most ImageJ
dialogs. For sure, it does not reappear. If it reappears, this must be
your code that calls it again.
Quickly looking at the code, it seems to me that closing the dialog box of
IJ.showMessageWithCancel makes it return true. This makes sense if the
user should 'cancel' only in special cases.
If you want it to return false when closed without pressing a button,
simply copy the code from IJ.showMessageWithCancel and return
gd.wasOKed(), e.g.:
/** Displays a message in a dialog box with the specified title.
Returns true only if the user pressed "OK". */
static boolean showMessageReturnOKed(String title, String msg) {
GenericDialog gd = new GenericDialog(title);
gd.addMessage(msg);
gd.showDialog();
return gd.wasOKed();
}
Michael
