22 CHAPTER 2. GRAPHICAL USER INTERFACE step by step. HDevelop executes the operator directly to the right of the green arrow, which is used as the program counter (È) (see chapter 2.4). The mouse pointer changes its shape to a clock. This indicates that HDevelop is active and not available for any user input. After the operator has terminated, all computed values are assigned to their respective variables that are named in the ouput parameter positions. Their graphical or textual representation in the variable window is also replaced. If iconic data has been computed, you will see its presentation in the current graphics window. In the status bar of the program window the operator runtime is indicated (if the time measurement has not been deactivated). The È is set before the next operator to execute. If the operators are specified in a sequential order, this is the textual successor. In case of control statements (e.g., ººº Ò or ÓÖ ººº ÒÓÖ), the È is set on the end marker (e.g., Ò or ÒÓÖ) after the execution of the last operator inside the statement’s body. After ÒÓÖ and ÒÛÐ the È is always set on the beginning of the loop. If a condition (as or ÛÐ) evaluates to ÄË, theÈ is set behind the end marker. Suggestions in the menu ËÙ×ØÓÒ× are determined for the recently executed operator. Finally the mouse pointer’s shape switches to the arrow shape and HDevelop is available for further transactions. Any user input which has been made during execution is handled now. ÜÙØ º ËØÓÔ (keyboard shortcut ) You may terminate the execution of a program (mode ÊÙÒ) by selecting ÜÙØ º ËØÓÔ. If you do so, HDevelop continues processing until the current operator has completed its computations. This may take a long time if the operator is taking a lot of time to execute. There is no way of interrupting a HALCON operator. After interrupting a program you may continue it by selecting ÜÙØ º ÊÙÒ and ÜÙØ º ËØÔ. Youmay even edit the program before restarting it (e.g., by parameter modification, by exchanging operators with alternatives, or by inserting additional operators). ÜÙØ º ØÚØ, Ø º ØÚØ It is often useful for testing purposes to prevent some lines of the program from being executed. This can be done by selecting the appropriate lines in the program window and calling ÜÙØ º ØÚØ from the menu. With this, an asterisk is placed on the beginning of the selected lines, and hence appear as comments in the program window. They have no influence on the program during runtime. The deactivated lines are still part of the program, i.e., they are stored like all other lines in a file and their variables are still needed like all other variables. To reverse this action you may press item Ø º ØÚØ. Note that you can insert a comment into your program by using the operator ÓÑÑÒØ. ÜÙØ º Ê×Ø ÈÖÓÖÑ With the menu item ÜÙØ º Ê×Ø ÈÖÓÖÑ you can reset the variables of the current program to their initial states, i.e., all variables have undefined values. Furthermore, the break point is cleared and the program counter is set to the first executable line of the program. This menu item is useful for testing and debbuging of programs. ÜÙØ º ÐÖ Ö ÈÓÒØ The menu item ÜÙØ º ÐÖ Ö ÈÓÒØ is used to clear the break point. This is often useful when the current program is long and you want to avoid having to scroll the program window to locate the break point. HDevelop / 2000-11-16
2.3. MAIN WINDOW 23 2.3.2.4 The Menu Item Î×ÙÐÞØÓÒ All items which can be selected are shown in figure 2.11: Figure 2.11: Submenu ËÔ of menu Î×ÙÐÞØÓÒ. With this you are able to open or to close graphics windows and to clear their displays. Furthermore, you may specify their output behavior during runtime. Î×ÙÐÞØÓÒ º ÇÔÒ ÏÒÓÛººº By using this menu item, you open additional 2 graphics windows. For this, a dialog window pops up (see figure 2.12). Here you may specify some graphics windows attributes. The position, size and background color of the new graphics window can be specified. For example, it is more convenient to have a white background while building graphics for slides or reports (see the HALCON operator ÙÑÔ ÛÒÓÛ). If the window height and width are set to -1, the window obtains the same size as the largest image in the current session. A position value of -1 specifies that the window position is determined by the window manager (UNIX). If you have not already created an image, the size ½¾ ¢ ½¾ is used. The handling of graphics windows is described in chapter 2.7 at page 56. 2 Normally upon starting, HDevelop automatically opens one graphics window. HALCON 6.0
