+ * @short A password input dialog.

+ * This dialog asks the user to enter a password. The functions you're

+ * getNewPassword().
+ *
+ * <b>Usage example</b>\n
+ *
+ * \code
+ * TQCString password;
+ * int result = KPasswordDialog::getPassword(password, i18n("Prompt message"));
+ * if (result == KPasswordDialog::Accepted)
+ * use(password);
+ * \endcode
+ *
+ * \image html kpassworddialog.png "KDE Password Dialog"
+ *
+ * <b>Security notes:</b>\n
+ *
+ * Keeping passwords in memory can be a potential security hole. You should
+ * handle this situation with care.
+ *
+ * @li You may want to use disableCoreDump() to disable core dumps.
+ * Core dumps are dangerous because they are an image of the process memory,
+ * and thus include any passwords that were in memory.
+ *
+ * @li You should delete passwords as soon as they are not needed anymore.
+ * The functions getPassword() and getNewPassword() return the
+ * password as a TQCString. I believe this is safer than a TQString. A QString
+ * stores its characters internally as 16-bit wide values, so conversions are
+ * needed, both for creating the TQString and by using it. The temporary
+ * memory used for these conversion is probably not erased. This could lead
+ * to stray passwords in memory, even if you think you erased all of them.
