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: CATCHER_V1 PURPOSE: EPICS 3.12.2 Scan record data acquistion tool. This program provides the EPICS user a convenient IDL data acquistion tool. It calls the IDL external CA functions which are defined in the ezcaIDL package. Currently, this program can capture both 1D and 2D scan data through setting monitor on the EPICS scan record. During data acquisition it also provides real-time plotting. Post acquisition it also provides primitive 1D and 2D post data plot and analysis. Each scan record can support up-to four positioners and fifteen detectors." CATEGORY: Widgets. CALLING SEQUENCE: CATCHER_V1 INPUTS: None KEYWORD PARAMETERS: CONFIG: Specifies the configuration file to be saved when data catcher is normally terminated. If not specified, the default configuration file name 'catch1d.config' is assumed. DATA: Specifies the data file name to be used for appending new captured scan data. If not specified, the default data file name 'catch1d.trashcan.xdr' is assumed. ENVFILE: Specifies the environment (process variables) file to be saved with the captured scan data. If not specified, the default environment file name 'catch1d.env' is assumed. NOSAVE: Turns off the autosave feature. If it is specified, the data catcher will be able to display the life data but data will not be recorded. VIEWONLY: Runs the data catcher as a scan data browser. If it is specified, it can only display the recorded scan data from a saved data file. 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 CATCHER_V1. OUTPUTS: It provides realtime plot and various post acquistion 1D and 2D surface plot. In addition of DATA file is saved, if 2D scan is detected the DATA.image file will also be saved at the end of 2D scan. Various levels of report files can also be generated by this program. All the file generated will be prefixed by the DATA file name. COMMON BLOCKS: CATCH1D_COM W_PLOTSPEC_BLOCK W_VIEWSCAN_BLOCK REALTIME_BLOCK ENV_FIELD_BLOCK FIELD_BLOCK SIDE EFFECTS: It is capable to detect scan invoked by outside channel access client. RESTRICTIONS: Supports EPICS 3.12.2 and later scan record. PROCEDURE: For live data acquisition: boot the IOC first, setup and initialize the scan records, setup the run ezcaIDL environment, run IDL, then start up the data catcher at the IDL prompt. A simplified UNIX script file catcher can be used for starting up this program. For help on catcher enter "catcher -h" at the UNIX prompt. EXAMPLE: Use default setting for config, envfile, and data file CATCHER_V1 Override the default setting for config, envfile, and data file, the 'test' is used for this example.

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.
