The PROGRESS control declares a control that displays a progress bar. This usually displays the current percentage of completion of a batch process.

If a variable is named as the USE attribute, the progress bar is automatically updated whenever the value in that variable changes. If the USE attribute is a field equate label, you must directly update the display by assigning a value (within the range defined by the RANGE attribute) to the control's runtime property (PROP:Progress).

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.

Color

Enter a valid color equate in the TextColor or BackGround fields, 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

Design settings control visual elements you see in the Window Designer. These settings should not affect the window display at runtime.

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.
UseVisualStyles Set to TRUE to display this control in a Visual Style appearance (as if the XP manifest was active)

Extra

Drop ID To specify the type of Drag operations this control will accept, type up to 16 signatures, separated by commas. The Window Designer adds the DROPID attribute to the control, which indicates the control is a valid target for the drag and drop operations identified by the signatures.
Range Specifies the range of values the progress bar displays. If omitted, the default range is zero (0) to one hundred (100).

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.
TextFont Calls the Font dialog which lets you select the font (typeface), size, style (such as bold or italic), color, and font effects (underline and strikeout) for the selected control or window. As you choose options, the dialog box displays a sample of the selected font.
Use This defines the USE attribute for the control. The field equate label references the control in program statements.

Help

Cursor The Cursor field (the CURSOR attribute) lets you specify an alternate shape for the cursor when the user passes the cursor over the control. The drop-down list provides standard cursor choices such as I-Beam and Crosshair. To select an external cursor file (whose extension must be .CUR), choose Select File from the drop-down list, then pick the file using the standard file dialog.

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. Set the Scroll property to 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.
Transparent Specify whether you wish the control background to be Transparent. This instructs Windows to suppress the rectangular region around the text–the background. Normally, Windows will paint this the same uniform color as the window below the control. This adds the TRN attribute.

Options

Vertical Set the Vertical property to True to allow the progress control to operate from the bottom of the control to the top. If your progress control is positioned in a horizontal (left to right) display format, you should resize the progress control accordingly.
Smooth Set the Smooth property to True to allow a smooth incremental display of the progress control instead of the standard “block” format.

Position

Lets you set the location and size of the control.

The Position property 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.
Value 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.
