NAME: BOX_CURSOR PURPOSE: Emulate the operation of a variable-sized box cursor (also known as a "marquee" selector). CATEGORY: Interactive graphics. CALLING SEQUENCE: BOX_CURSOR, x0, y0, nx, ny [, INIT = init] [, FIXED_SIZE = fixed_size] INPUTS: No required input parameters. OPTIONAL INPUT PARAMETERS: x0, y0, nx, and ny give the initial location (x0, y0) and size (nx, ny) of the box if the keyword INIT is set. Otherwise, the box is initially drawn in the center of the screen. KEYWORD PARAMETERS: INIT: If this keyword is set, x0, y0, nx, and ny contain the initial parameters for the box. FIXED_SIZE: If this keyword is set, nx and ny contain the initial size of the box. This size may not be changed by the user. MESSAGE: If this keyword is set, print a short message describing operation of the cursor. OUTPUTS: x0: X value of lower left corner of box. y0: Y value of lower left corner of box. nx: width of box in pixels. ny: height of box in pixels. The box is also constrained to lie entirely within the window. COMMON BLOCKS: None. SIDE EFFECTS: A box is drawn in the currently active window. It is erased on exit. RESTRICTIONS: Works only with window system drivers. PROCEDURE: The graphics function is set to 6 for eXclusive OR. This allows the box to be drawn and erased without disturbing the contents of the window. Operation is as follows: Left mouse button: Move the box by dragging. Middle mouse button: Resize the box by dragging. The corner nearest the initial mouse position is moved. Right mouse button: Exit this procedure, returning the current box parameters. MODIFICATION HISTORY: DMS, April, 1990. DMS, April, 1992. Made dragging more intutitive. June, 1993 - Bill Thompson prevented the box from having a negative size. 04-18-96 bkc Made the box color more visible. 05-28-98 bkc Reset bounding box color

NAME: VIEW1D PURPOSE: This program is specially written for the data catcher. It provides the IDL user a convenient post data acquisition 1D data display program. It shares the common 1D data file with data catcher without interrupting the process of data scanning of data catcher. CATEGORY: Widgets. CALLING SEQUENCE: VIEW1D [,Data='test.dat'] [,Config='test.config'] [,/XDR] [GROUP=Group] INPUTS: None KEYWORD PARAMETERS: CONFIG: Specifies whether the configuration file to be used in the startup of the VIEW1D. DATA: Specifies the 1D file name to be used for displaying captured 1D scan data. If not specified, the default data file name 'catch1d.trashcan' is assumed. XDR: Indicates whether the data file entered on the command line is in XDR format. GROUP: The widget ID of the group leader of the widget. If this keyword is specified, the death of the group leader results in the death of VIEW1D. OUTPUTS: It provides various post acquistion 1D scan displaying features. Various levels of report files can be generated by this program. All the file generated will be prefixed by the DATA file name. COMMON BLOCKS: VIEW1D_COM W_PLOTSPEC_BLOCK W_VIEWSCAN_BLOCK SIDE EFFECTS: New scan data may be appended at the end of data file if the data catcher is runing at the same time and new data is detected by the data catcher. Reload the data file will let you access the newly captured scan data from the file. RESTRICTIONS: PROCEDURE: The 'os.init' must be loaded into IDL before invoking the VIEW1D application. EXAMPLE: Use default setting for view1d VIEW1D Override the default setting by specifying config and data file on the command line VIEW1D, CONFIG='test.config', DATA='test.dat' MODIFICATION HISTORY: Written by: Ben-chin K.

NAME: XDISPLAYFILE PURPOSE: Display an ASCII text file using widgets and the widget manager. CATEGORY: Widgets. CALLING SEQUENCE: XDISPLAYFILE, Filename INPUTS: Filename: A scalar string that contains the filename of the file to display. The filename can include a path to that file. KEYWORD PARAMETERS: FONT: The name of the font to use. If omitted use the default font. GROUP: The widget ID of the group leader of the widget. If this keyword is specified, the death of the group leader results in the death of XDISPLAYFILE. HEIGHT: The number of text lines that the widget should display at one time. If this keyword is not specified, 24 lines is the default. TEXT: A string or string array to be displayed in the widget instead of the contents of a file. This keyword supercedes the FILENAME input parameter. TITLE: A string to use as the widget title rather than the file name or "XDisplayFile". WIDTH: The number of characters wide the widget should be. If this keyword is not specified, 80 characters is the default. BLOCK: Set this keyword to have XMANAGER block when this application is registered. By default the Xmanager keyword NO_BLOCK is set to 1 MODAL: OUTPUTS: No explicit outputs. A file viewing widget is created. SIDE EFFECTS: Triggers the XMANAGER if it is not already in use. RESTRICTIONS: None. PROCEDURE: Open a file and create a widget to display its contents. MODIFICATION HISTORY: Written By Steve Richards, December 1990 Graceful error recovery, DMS, Feb, 1992. 12 Jan. 1994 - KDB If file was empty, program would crash. Fixed. 4 Oct. 1994 MLR Fixed bug if /TEXT was present and /TITLE was not. 14 Jul. 1995 BKC Increased the max line to variable size. 16 Jun. 1997 BKC Max dispalyable line is 10000 for non-unix OS system. 28 Aug. 1997 BKC Add the printer button, file name label, it uses the PS_print,file to print. 30 Jul. 2002 BKC Add the block, modal keywords take care the animation help problem 09 Aug 2002 BKC fix the problem with no input filename case
