The line control lets you place a straight line in your window or report. You specify a color. The line control cannot receive focus, nor can it generate events.

The Property View presents you with two ways to viewing a control's properties.

At the top of the Property View, press the categorized button categorized.jpg to view a control's properties by category (the deafult).

Or press the alphabetical button alphabetical.jpg to view a control's properties in alphabetical order.

This help documents displays the properties in the categorical view.

Colors

Enter a valid color equate in the LineColor property, or press the ellipsis (…) button to select a color from the Color dialog. The Window Designer adds the COLOR attribute to your control declaration.

See ..\LIBSRC\EQUATES.CLW for a list of valid color equates. See Windows Design Issues in the User's Guide for a discussion on using color to enhance your application.

Design

Locked “Freezes” the control so that subsequent data dictionary changes are not applied. You can override the #Freeze attribute for all controls or for individual controls. See Application Options.
Tab Index Determines the index in the TAB order that this control will follow. The first tab in the order is index zero (0).To change the TabIndex property immediately while in the Designer, use the Show tab order interface (i.e. on the right-click menu).If you set the TabIndex property using the property page, the z-order is not updated until you save and exit the Window Designer.

General

Layout Indicates the orientation of the control. Left to Right maintains the original layout specified in the Window Designer. Right to Left essentially “flips” the controls' display as a mirror image of the layout specified in the Window Designer. Default field navigation moves from right to left. The setting in the Application Frame will cascade its setting to all child windows and controls that have the default setting active.
Line Width Set the line's thickness by entering a point value in the Line Width spin control. The default is 1 point.
Use This defines the USE attribute for the control. Type a field equate label to reference the control in executable code.

Mode

Disable Disables or 'grays-out' the control when your program initially displays it. The Window Designer places the DISABLE attribute on the control. Use the ENABLE statement to allow the user access to the control.
Hide Makes the control invisible at the time Windows would initially display it. Windows actually creates the control–it just doesn't display it on screen. The Window Designer places the HIDE attribute on the control. Use the UNHIDE statement to display the control.
Scroll Specifies whether the control should move with the window when the user scrolls the window. By default, (False), the control does not move with the window. Leave the Scroll property False to create a control that stays fixed when the user scrolls the window. The Window Designer places the SCROLL attribute on the control when checked.

Position

Lets you set the location and size of the control.

The Position tab lets you specify the AT attribute. Filling in the attribute manually is optional–you may set the position and size visually by dragging with the mouse in the Window Designer.

To set the location of the control's Top Left Corner, set an X (horizontal) and Y (vertical) coordinate in Dialog units. The coordinate is relative to the top left corner of the structure containing it, that is, the window or the report band.

To set the control's size, choose from the following options for Width and Height.

Default The Clarion runtime library determines the size of the control based on the applicable font and picture token.
Full The control is the full height or width of the window or report.
Fixed Lets you set a precise width or height in Dialog units on a window, or in thousandths of inch, points, or millimeters on a report.

A height of zero(0) specifies a horizontal line. A width of zero(0) specifies a vertical line.
