Special Widgets

F
ile Widget

• 
  The file widget is used whenever a system filename is needed for importing or exporting data.
  
• 
  The File widget is built up of many standard widgets and allows for customization of databox labels, listbox labels and file type filtering.
  

• 
  T
  file_widget=ui_file_create( @
  /* parent */ form_id, @
  /* callback */ "file_cb", @
  /* x */ FORM_L_MARGIN, @
  /* y */ FORM_T_MARGIN, @
  /* width */ FILE_WID_DOUBLE, @
  /* rows */ 6, @
  /* filterlabel */ "Filter", @
  /* filter mask */ "*.db", @
  /* Dir label */ "Directories", @
  /* files label */ "Database List", @
  /* Select label*/ "Existing Database Name",@
  /* Selection */ "", @
  /* OK label */ "OK", @
  /* filt btn lab*/ "Filter", @
  /* Cancel label*/ "Cancel")
  
  
  Note: The height of a file widget with 6 rows (lines) is FILE_6L_HGT.
  he headers and filter labels are customizable allowing for adaptation to the specific file type.
  

• 
  The File widget callback function is executed when the Ok/Apply or Cancel button is selected.
  

Special Widgets

Spreadsheet Widget

• 
  The Spreadsheet widget was developed by MSC.Software for use in MSC.Patran. The spreadsheet widget can be used for displaying or entering data.
  
• 
  The spreadsheet widget performs a callback when a cell or group of cells is selected. The starting and ending columns and rows, and the layer if 3 dimensional, are returned as callback function arguments.
  
• 
  To enter data into a spreadsheet, you will need to create a databox.
  
• 
  Use the ui_spread_set_cell(s) functions to set the cells of a particular spreadsheet.
  
  
  
  
  
  

Exercise 11: File Widget

Create a form with a file widget for use with your function that writes nodal data (Exercise 4). Do the same for your function to read nodal data (Exercise 5).

Extra Credit: Suppose your form with a file widget is a secondary form, i.e., it is opened from a button on a primary or main form. Typically, action occurs or a command is executed when the “Apply” button on the main form is pressed. How do you transfer the filename information from the secondary form to the primary form?

Adding Help/Description to your PCL

• 
  One way to add “help” to your PCL is to create your own form which contains a text widget (ui_text_create).
  
• 
  An easier way is to use the shareware help functions
  
  FUNCTION description_cb()
  
  shareware_help.set_alltext(“Aero Preference”, @

  “PURPOSE:\n”//@

  “For comments/remarks, send an email to:\n”//@

  “elvis.mscsoftware.com”)

  
  
  END FUNCTION
  
  
  
  

  Or, to read the help text from a file, use:

  
  
  shareware_help.set_allinfile(“Aero Preference”, “aero_help.txt”)
  

Percent Complete

Functions

• 
  MSC.Patran provides PCL functions to allow the user to create, update, and manage the percent complete form.
  

• 
  uil_pcntcomplete.initlz(…) is used to initialize the percent complete form.
  
• 
  uil_pcntcomplete.update(…) is used to update the percent complete form
  
• 
  uil_pcntcompete.close(…) is used to close the form. Don’t forget to close the form!
  

Example

FUNCTION calc_elm_normals(num_elms, elm_ids, normal_vec)

INTEGER i, num_elms, elm_ids()

REAL normal_vec()

STRING msg[80]

msg = “Processing “//str_from_integer(num_elms)//” elements …”

uil_pcntcomplete.initlz(msg)

FOR (i = 1 to num_elms)

/* functions that calculate element normals */

uil_pcntcomplete.update(i*100.0/num_elms)

END FOR

uil_pcntcomplete.close()

RETURN (0)

END FUNCTION /* calc_elm_normals */
