48 CHAPTER 2. GRAPHICAL USER INTERFACE 2.4 Program Window The program window is divided into two areas. The left one (a small column) contains the program counter (È, represented as a green arrow pointing to a program line), the insertion cursor (a triangle between two program lines) and optionally a breakpoint (È — a red STOP sign). You may position or activate these three labels as follows: ¯ The È is set by pressing the left mouse button only. ¯ The insertion cursor is set by pressing the left mouse button and the ËØ key. ¯ The È is set by pressing the left mouse button and the ØÖÐ key. The program counter resides in the line of the next operator to execute. The insertion cursor indicates the position to insert a new program line. The breakpoint shows the program line before which the program is stopped. Clicking on the breakpoint again while pressing the ØÖÐ key deletes it. A breakpoint is active only if it is visible. You may activate only one breakpoint. In figure 2.33 you see a program and the column with the È (indicated as an arrow), the È and the insertion cursor. Figure 2.33: Program example with the È (the arrow pointing to the right), insertion cursor and the the breakpoint (È). The big text area at the right side of the program window contains the program code of the HDevelop program. Here the user has the possibility to obtain information about the inserted operators. A program is built up such that every line contains exactly one operator with its parameters or an assignment. An exception are the condition constructs and Ð× respectively, and the loop constructs ÛÐ and ÓÖ. They contain two, in case of Ð× even three, program lines, which enclose the body. Every line starts with an operator name, which is indented if necessary, to highlight the structure created by the above mentioned control structures. After the operator name the parameters are displayed in parentheses. Parameters are separated by commas. HDevelop / 2000-11-16
2.5. OPERATOR WINDOW 49 The program window is used to visualize program lines, but not to modify them. You cannot change a program by modifying the text directly. Editing the program text in HDevelop is done in the operator window (this will be described below). The main reason for this principle is the advantage of providing sophisticated help. Thus you are able to avoid many input errors. To edit a line of a program you chose an operator in the program window by clicking the left mouse button twice. In case of conditions and loops it is unimportant which lines (e.g., ÓÖ or ÒÓÖ) are selected. In any case, the head with its parameters is selected. You may edit only one operator at a time. Besides editing the parameters of a single operator, single and multiple lines can be deleted, cut, or pasted in one step using simple mouse functions. To use this feature, one has to select one or more lines using the mouse: ¯ The selection of one line is done by clicking on it. Previously activated lines will then become deactivated. ¯ To activate more than one line you have to press the ØÖÐ key while clicking on the line. If the line is already activated it will become deactivated, while the state of all other lines remains unchanged. ¯ The ËØ key is used to activate a sequence of lines using one mouse click: All lines between the most recent activation and the new one will become activated. After the selection of lines, the edit function can be activated by either using the menu Ø (see sections 2.3.2.2) or the tool bar (see sections 2.3.3). Further information on the use of the mouse can be found in section 2.2. 2.5 Operator Window This window is mainly used to edit and display an operator and all its parameters. Here you will obtain information about the number of the operator’s parameters, the parameter types, and parameter values. You are able to modify the parameter values according to your image processing tasks. For this you may adopt the proposed system values or specify your own values. The operator window consists of the following three parts: ¯ The first one is the operator text field. ¯ The second one is the largest part. It is called parameter display and is used to edit the parameters of an operator. ¯ The last one is a row of buttons to control the parameter display. 2.5.1 Operator Name Field The operator name field is another possibility to select operators. You simply have to enter a substring of an operator name. By pressing ÊØÙÖÒ or pressing the button of the combo box the system is looking for all operators (in the menu ÇÔÖØÓÖ×) that contain the user-specified substring (see figure 2.34). If there is an unambiguous search result, the operator is displayed HALCON 6.0
