Description

Enters a multisegment line in the current window.

Arguments

?prompts l_promptList

  

List of prompt strings to be displayed in the CIW.

?points l_pointList

  

List of points to start the line. If specified, all points are adjusted. If the list terminates with two identical points, the adjusted points are returned with no further interaction. Otherwise, the given points are displayed with connecting lines and a rubberbanding line is drawn from the last point to the current cursor position. Each successive point entered causes a new permanent segment between that point and the previous point.

The function terminates when two identical points are entered or when the function is explicitly terminated with finishEnterFun or cancelEnterFun.

?wantPoints x_pointLimit

  

Number specifying the maximum number of input points to be used. The function returns the list of points after it reaches this number. In this case, the last two points do not need to be identical to terminate the function.

?form s_form

Options form created with hiCreateOptionsForm. This form is displayed when you call hiToggleEnterForm. It contains options relevant to the enterfunction and its caller.

?addPointProc t_addProcName

  

Name of the SKILL function to be called when a point is entered.

?delPointProc t_delProcName

  

Name of the SKILL function to be called when a point is deleted.

?initProc t_initProcName

  

Name of the SKILL function to be called immediately after the enterfunction is started and before any data entry.

?doneProc t_doneProcName

  

Name of the SKILL function to be called when the enterfunction is terminated.

?formProc t_formProcName

  

Name of the SKILL function to be called when the options form is displayed.

?dontDraw g_dontDraw

  

Determines whether or not to draw rubberband lines.

?alwaysMap g_alwaysMap

  

Determines whether or not to immediately display the options form.

?acceptString g_acceptString

  

Determines whether or not to accept string input without terminating the enterfunction.

?acceptNumber g_acceptNumber

  

Determines whether or not to accept numeric input without terminating the enterfunction.

?noInfix g_noInfix

  

Determines whether or not to disable infix mode.

?cmdName t_cmdName

  

Name you associate with the enterfunction. If the command name is set, it can be accessed with hiGetCurrentCmd.

?cursor x_cursor

An integer argument that will default to an appropriate cursor. For example, hicArrowRectangle for enterBox and hicArrowArc for enterArc. For more information on all available cursors see hiSetCursor.

?target l_point

The target point to which a flight line is drawn from the current cursor.

Value Returned

l_point_list

The points you entered as a list containing the coordinates for a line.

nil

A nil list is returned.

Retrieve data through the callback procedure t_doneProcName instead of using the return value for this enterfunction.

Examples

Displays the prompt Enter the first point on the prompt line. When you enter point p1, the prompt changes to Enter the next point. A rubber band line appears between p1 and the current cursor location.

procedure( lineDone( w done pts )
   if( done then
      printf("Line entered was %L.\n" pts)
   else
      println("Line entry aborted.")
   )
)
enterLine( ?prompts
   list( "Enter the first point."
   "Enter the next point." )
   ?doneProc "lineDone"
)

Enter point p2 and the first segment becomes permanent, while the rubberbanding line now attaches the cursor to p2. Continue with p3. Enter p4 at the same location as p3. doneProc prints the following point list:

Line entered was ( p1 p2 p3 p4).

The enterLine function returns the point list:

( p1 p2 p3 p4 )
