The OPTION control declares a group of RADIO controls that offer the user a list of mutually exclusive choices. The multiple RADIO controls in the OPTION structure define the choices offered to the user.
The Property View presents you with two ways to viewing a control's properties.
This help documents displays the properties in the categorical view.
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.
|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 Transparency||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.|
|Bevel||Gives a three dimensional look to the control. The control appears raised, depressed, or both. The Window Designer adds the BEVEL attribute to your control declaration. Fine tune the bevel with the following prompts:|
|Outer||A positive value makes the control appear raised above the plane of the window. The higher the value, the further the box is raised. A negative value makes the control appear depressed below the plane of the window. The bevel effect begins at the outer border of the box.|
|Inner||A positive value makes the control appear raised above the plane of the window. The higher the value, the further the box is raised. A negative value makes the control appear depressed below the plane of the window. The bevel effect begins immediately inside the outer bevel.|
|Style||An integer constant or constant expression that specifies fine control of the bevel, overriding the signs of the outer and inner parameters (PROP:BevelStyle).|
|Boxed||The BOXED attribute specifies a single-track border around the OPTION structure. The parameter text of the OPTION control appears in a gap at the top of the border box. If BOXED is omitted, the text parameter is not displayed on screen|
|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.|
|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.|
|Text||Specify a string constant by typing it in the Text box. If the control is to display a variable, type a picture token in this box.|
|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. Type a field equate label to reference the control in executable code, or the name of a variable|
|Alert||Press the ellipsis to open a dialog that lets you add the ALRT attribute to a window or control. When the attribute is set, the window generates an EVENT:AlertKey if the user presses the key(s) you specify in this dialog, while the window has the focus.|
|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.|
|HelpID||The HelpID field (the HLP attribute) takes a string constant specifying the key for accessing a specific topic in the Help document. This may be either a Help keyword or a context string.|
|A Help keyword is a word or phrase indexed so that the user may search for it in the Help Search dialog. When you fill in the HLP attribute for a button, if the entry box has focus, when the user presses F1, the help file opens to the referenced topic. If more than one topic matches a keyword, the search dialog appears.|
|When referencing a context string in the Help ID field, you must identify it with a leading tilde (~).|
|Key||Press the desired key or key combination (for example, CTRL+H). The keys you pressed will appear in the Key field, and will be supplied as parameters to the KEY or ALRT attribute for this control. The ESC, ENTER, and TAB keys cannot be specified by pressing them. For these keys, press the ellipsis (…) button and type “esc,” “enter,” or “tab.”|
|Message||The Message field (the MSG attribute) lets you specify text to display in the first zone of the status bar when the control has focus.|
|Tip||The TIP attribute on a control specifies the text to display in a “balloon help” box when the mouse cursor pauses over the control. Although there is no specific limit on the number of characters, the string should not be longer than can be displayed on the screen.|
|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.|
|Skip||Instructs the Window Designer to omit the control from the Tab Order. When the user TABS from field to field in the dialog box, Windows will not give the control focus. This is useful for seldom-used data fields. The Window Designer will place the SKIP attribute on the control.|
|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.|
Lets you set the location and size of the control.
The Position properties let you specify the AT attribute. Filling in the attribute manually is optional–you may also 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.|
|Embeds||Accesses the Embedded Source dialog for points surrounding the event handling for this control only.|
