CreateEditReal

Description

Creates an editable text field control for REAL values.

CreateEditReal is intended specifically for entry of numeric values; the control returns values in a numeric format, and supports calculations within the control field.

Table - Field Types for EditReal Fields

Index Field Value
1 REAL value
2 Angular value
3 Dimension
4 X coordinate
5 Y coordinate 
PROCEDURE CreateEditReal(
				dialogID          : LONGINT;
				itemID            : LONGINT;
				editRealType      : LONGINT;
				defaultValue      : REAL;
				widthInCharacters : LONGINT);
def vs.CreateEditReal(dialogID, itemID, editRealType, defaultValue, widthInCharacters):
    return None

Parameters

Name Type Description
dialogID LONGINT The index of the dialog layout containing the control.
itemID LONGINT The index that will identify the control item.
editRealType LONGINT The type of REAL value being accepted.
defaultValue REAL Default value for the field.
widthInCharacters LONGINT Width of the field in characters.

Remarks

Edits reals, does math, get and set values with get and set real calls.

There are 5 edit real types: *1 - Real, regular old real type; *2 - Angle, vs input and output is always in degrees but the user can use what ever they want; *3 - Dimension, usually an offset this a distance that is not tied to the origin; *4 - CoordinateX, this is an exact x location on the drawing; *5 - CoordinateY, this is an exact y location on the drawing. There are separate x and y controls to account for changes the user may make to the origin. I think Z coordinates should use the offset mode, but I need to check with mark on this one.

The default value parameter isn't worth much -- it plops the value into the edit box OK -- but it does not assign the value to the control. GetEditReal will return 0 for the control, unless the user clicks in the control. Use SetEditReal in your SetupDialogC event instead of using a default value for this control.

Accepts '3 1/4' and '3000000' but not '3,000,000'.

Examples

VectorScript

PROCEDURE Example;
VAR
dialog1 :INTEGER;
result  :INTEGER;
PROCEDURE Dialog_Handler(VAR item :LONGINT; data :LONGINT);
BEGIN
END;
BEGIN
dialog1 := CreateLayout('Example Dialog', FALSE, 'OK', 'Cancel');
CreateEditReal(dialog1, 4, 3, 123, 16);
SetFirstLayoutItem(dialog1, 4);
result := RunLayoutDialog(dialog1, Dialog_Handler);
END;
RUN(Example);

Python

def Dialog_Handler( item , data ):
	pass
def Example():
	dialog1 = vs.CreateLayout('Example Dialog', False, 'OK', 'Cancel')
	vs.CreateEditReal(dialog1, 4, 3, 123, 16)
	vs.SetFirstLayoutItem(dialog1, 4)
	result = vs.RunLayoutDialog(dialog1, Dialog_Handler)
Example()
