parameters for graphics windows; you may even modify the program. Note that
HDevelop may be slow to react to your actions while the program is running. This
is caused by the fact that HALCON reacts to user input only between calls to operators.
¯ A variable window update during runtime will only be performed if it has not been
suppressed (see page 24). In any case, the values of all variables are shown in the
variable window after the execution’s termination.
While the program is running, the menus ÜÙØ º ÊÙÒ and ÜÙØ º ËØÔ (and the
toolbar buttons ÊÙÒ and ËØÔ) are grayed out, i.e., you cannot execute them. You have
the following possibilities to stop your HDevelop program:
1. The program runs until the last operator in this program has been called. The È
is positioned behind this operator. This is the usual way to terminate a program.
2. The menu ÜÙØ º ËØÓÔ (or the toolbar button ËØÓÔ) has been pressed.
3. A breakpoint has been set (see chapter 2.4). In this case the last operator that will
be executed is situated before the breakpoint.
4. Menu item Ð º ÉÙØ has been executed (see page 19).
5. A runtime error occurred. An input variable without a value or values outside a
valid range might be typical reasons. In this case the È remains in the line of the
erroneous operator.
