38 CHAPTER 2. GRAPHICAL USER INTERFACE ÇÔÖØÓÖ× º ÚÐÓÔ This menu contains several operators that help to adapt the user interface. These operators offer the same functionality that you have using mouse interaction otherwise. They are used to configure the environment without (or with little) user interaction. Using these operators, the program performs actions similar to the setting of a color in the parameter window (see section 2.7), opening a window in the menu bar (see section 2.3.2.4) or iconifying the program window with the help of the window manager. All operators in this menu start with the prefix Ú . It has been introduced to have a distinction to the underlying basic HALCON operators (e.g., Ú ×Ø ÓÐÓÖ and ×Ø ÓÐÓÖ). You can find the complete listing in figure 2.24. Figure 2.24: Operators in menu item ÚÐÓÔ. The effects of each operator are described as follows: ¯ Ú ÓÔÒ ÛÒÓÛ¸ Ú ÐÓ× ÛÒÓÛ¸ Ú ÐÖ ÛÒÓÛ The operators Ú ÓÔÒ ÛÒÓÛ and Ú ÐÓ× ÛÒÓÛ are used to open and to close a graphics window, respectively. During opening, the parameterization allows you to specify the window’s size and position. The operator Ú ÐÖ ÛÒÓÛ clears the active window’s content and its history. This corresponds to the usage of the button ÐÖ in the graphics window. Please note that Ú ÓÔÒ ÛÒÓÛ and Ú ÐÓ× ÛÒÓÛ are not supported for Visual Basic export because here one ÀÏÒÓÛØÖÐ is used. ¯ Ú ×Ø ÛÒÓÛ ÜØÒØ× With this operator, you can set the size and position of the active HDevelop graphics window. ¯ Ú ×Ø ÛÒÓÛ This operator activates the graphics window containing the given ID. This ID is an HDevelop / 2000-11-16
2.3. MAIN WINDOW 39 output parameter of Ú ÓÔÒ ÛÒÓÛ. After the execution, the output is redirected to this window. This operator is not needed for exported code in C++, because here every window operation uses the ID as a parameter. The operator has no effect for exported code in Visual Basic. ¯ Ú ×Ø ÓÐÓÖ¸ Ú ×Ø ÓÐÓÖ Ú ×Ø ÓÐÓÖ has the same effects as the menu item Î×ÙÐÞØÓÒ º ÓÐÓÖ. Ú ×Ø ÓÐÓÖ is equal to the menu item Î×ÙÐÞØÓÒ º ÓÐÓÖ. ¯ Ú ×Ø ÖÛ This operator has the same effects as Î×ÙÐÞØÓÒ º ÖÛ. ¯ Ú ×Ø ÐÒ ÛØ For an explanation see item Î×ÙÐÞØÓÒ º ÄÒ ÏØ. ¯ Ú ×Ø ÐÙØ For an explanation see item Î×ÙÐÞØÓÒ º ÄÙØ. ¯ Ú ×Ø ÔÒØ For an explanation see item Î×ÙÐÞØÓÒ º ÈÒØ. If you want to specify all possible parameters of a given paint mode, you have to specify them as a tuple, analogously to the HALCON operator ×Ø ÔÒØ. ¯ Ú ×Ø ×Ô For an explanation see item Î×ÙÐÞØÓÒ º ËÔ. ¯ Ú ×Ø ÔÖØ This operator adjusts the coordinate system for image, region, XLD and other graphic output. This is done by specifying the upper left and the lower right corner coordinates. This specified part is shown in the entire graphics window. If the width or height of the specified rectangle has a negative value (e.g., ÊÓÛ½ ÊÓÛ¾) the result is equivalent to the menu Î×ÙÐÞØÓÒ º ÓÓÑÒ º Ê×Ø: the zoom mode is switched off, i.e., the most recently displayed image fills the whole graphics window. This feature of Ú ×Ø ÔÖØ is not supported for exported C++ and Visual Basic code. ¯ Ú ×ÔÐÝ Iconic variables are displayed in the active graphics window by this operator. It is reasonable to do this when the automatic output is suppressed (see Ú ÙÔØ ÛÒÓÛ and Ð º ÇÔØÓÒ×ººº on page 17). ¯ Ú ÐÖ Ó This operator deletes the iconic object stored in the HDevelop variable that is passed as the input parameter. In the variable window, the object is displayed as undefined (with a as its icon). ¯ Ú Ò×ÔØ ØÖÐ This operator opens an inspection window displaying the values of the variable passed to the operator. In most cases a list dialog is opened, which shows all values of the variable. In the case of a frame grabber handle, a description of this frame grabber is opened. In addition, this dialog allows online grabbing of images. This operator is not supported for exported C++ and Visual Basic code. ¯ Ú ÐÓ× Ò×ÔØ ØÖÐ HALCON 6.0
