The String control lets you place a string constant in a window or report. It optionally lets you substitute a variable.

NoteBox.jpg

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

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.
Suppress TransparencySTBut.jpg Allows the proper display of special static parent controls when populated “on top of” multiple tab controls. This property is set to TRUE by default, and ensures a proper display regardless of Visual Styles used. No effect on runtime window.
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.

Extra

Angle Specify the angle of the text. An angle other than zero requires a TrueType font. Adds the ANGLE attribute to the STRING. With this, you can rotate the text from its normal horizontal position through a full 360 degrees.TipBox.jpgMake the control taller than usual to accommodate the slant of the text.
DropID 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.
Extend Valid in REPORT only. Enter a valid string of attributes that are assigned to a designated REPORT control for a given document type. For more information, see EXTEND.
Tallies Valid in REPORT only. The total is calculated each time a highlighted structure in the Tallies list prints. This list is available only from the Report Designer and only when the Variable String box is checked. Use the Tallies list in conjunction with the Total Type and Reset On lists on the General tab to generate a custom total field. The Report Designer adds the TALLY attribute to the string.

General

Justification Specify left, center, right, decimal, or default justification. Default justification matches that specified in the data dictionary, if applicable. If you use decimal justification, you set the Offset to allow display of digits to the right of the decimal point.
Offset Specify an indentation value for the text, in dialog units for a window, or the default measurement unit for a report. This provides the indent parameter for the left, center, right, or decimal, justification attribute.
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.
IsPicture (Variable String) Optionally set this property to True to specify that you want to display the contents of a variable in the string control. This opens the Select Field dialog where you can select or define the variable. Place a picture token in the Picture box, such as @s24, and name the variable in the Use field.
Picture For Variable Strings (see IsPicture), specify the picture token for the control. Press the ellipsis button to select the picture token from the Edit Picture String Dialog .
Text For Constant Strings (IsPicture=False), specify the constant by typing it in the Text box.
TextFont Calls the Select Font dialog which lets you change 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. Type a field equate label to reference the control in executable code, or the name of a variable. Press the ellipsis button to select or define a variable.

REPORT only properties:

Reset On This drop down list is available only from the Report Designer, and only when the Variable String box is checked. To create page totals or group totals, use the Reset On drop down list in conjunction with your Total Type selection. Reset your totals at the beginning of each Page, or at the beginning of any BREAK group within the report.
Total Type This drop down list is available only from the Report Designer, and only when the Variable String box is checked. Choose from this drop down list to implement one of Clarion's built in report totaling functions. Choose from Sum, Average, Maximum, Minimum, Count, and Page No.To create page totals or group totals, use the Reset On drop down list and the Tallies list on the Extra tab in conjunction with your Total Type selection. Totals are calculated or tallied each time a structure in the Tallies list prints. Totals are reset each time the Reset On structure prints.
Using The label of a numeric variable to receive the intermediate values calculated for the SUM, AVE, MAX,MIN, CNT, or PAGENO. This allows you to create totals on other totals. The value in the variable is internally updated by the print engine, so it is only useful for use within the REPORT structure. This is only available when a Total Type is specified.

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

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.
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.
Scroll Valid only on a WINDOW. 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.
Skip Valid only in a REPORT. Check this box to specify not to print the control if the content is blank, and to move all following controls in the band upward to “fill in” the blank (PROP:SKIP).
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.

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.
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.
