CheckBox control

CheckBox controls are small square boxes used to set independent options. When they are selected, they display a mark (typically, either an X or a check mark). When they are not selected, they are empty.

Since check boxes are independent of each other, you can group them without affecting their behavior. Grouping check boxes makes the window easier for the user to understand and use.

Typically, check boxes have two states: on and off. You can also use a third state, unknown or unspecified. In the third state, the check is grayed.

Properties

CheckBox property	Datatype	Description
AccessibleDescription	String	A description of the control and/or its purpose for use by accessibility tools such as readers for visually impaired users.
AccessibleName	String	A label that briefly describes the control, such as the text in a button or the name of a menu item.
AccessibleRole	AccessibleRole (enumerated)	Describes what kind of user interface element the control is.
Automatic	Boolean	Specifies whether the control displays a mark when the user clicks it. Values are: TRUE – Displays mark when clicked. FALSE – Does not display mark when clicked.
BackColor	Long	Specifies the numeric value of the background color: –2 to 16,777,215. For more information about color, see the RGB function in the PowerScript Reference.
BorderStyle	BorderStyle (enumerated)	Specifies the style of the border of the control. Values are: StyleLowered! StyleRaised!
BringToTop	Boolean	Specifies whether PowerBuilder moves the control to the top of the front-to-back order. Values are: TRUE – Move to the top. FALSE – Do not move to the top.
Checked	Boolean	Specifies whether the control is selected. Values are: TRUE – Control is selected. FALSE – Control is not selected.
ClassDefinition	PowerObject	An object of type PowerObject containing information about the class definition of the object or control.
DragAuto	Boolean	Specifies whether PowerBuilder puts the control automatically into Drag Mode. Values are: TRUE – When the control is clicked, the control is automatically in Drag Mode. FALSE – When the control is clicked, the control is not automatically in Drag Mode. You have to put the control into Drag Mode manually by using the Drag function.
DragIcon	String	Specifies the name of the stock icon or the file containing the icon you want to display when the user drags the control (the ICO file). The default icon is a box the size of the control. When the user drags the control, the icon displays when the control is over an area in which the control can be dropped (a valid drop area). When the control is over an area that is not a valid drop area, the No-Drop icon displays.
Enabled	Boolean	Specifies whether the control is enabled (can be clicked). Values are: TRUE – Control can be clicked. FALSE – Control cannot be clicked.
FaceName	String	Specifies the name of the typeface in which the text of the control displays; for example, arial or courier.
FontCharSet	FontCharSet (enumerated)	Specifies the font character set used for the text in the control. The application must be running on an appropriate version of PowerBuilder under an operating system that supports the selected character set. For a complete list of possible values, see the list of properties for the FontCharSet variable on the Enumerated tab page of the Browser.
FontFamily	FontFamily (enumerated)	Specifies the font family (type style) used for the text in the control. Values are: AnyFont! Decorative! Modern! Roman! Script! Swiss!
FontPitch	FontPitch (enumerated)	Specifies the pitch (spacing) of the font used for the text in the control. Values are: Default! Fixed! Variable!
Height	Integer	Specifies the height of the control, in PowerBuilder units.
Italic	Boolean	Specifies whether the text in the control is italic. Values are: TRUE – Text is italic. FALSE – Text is not italic.
LeftText	Boolean	Specifies whether the text displays on the left of the control. Values are: TRUE – Text displays on left. FALSE – Text displays on right. Typically, you set this property to false so the text appears on the right of the control.
Pointer	String	Specifies the name of the stock pointer or the file containing the pointer used for the control.
RightToLeft	Boolean	Specifies that characters should be displayed in right-to-left order. The application must be running on an operating system that supports right-to-left display. Values are: TRUE – Characters display in right-to-left order. FALSE – Characters display in left-to-right order.
TabOrder	Integer	Specifies the tab value of the control within the window (0 means the user cannot tab to the control).
Tag	String	Specifies the tag value assigned to the control.
Text	String	Specifies the text that displays next to the control.
TextColor	Long	Specifies the numeric value of the color used for text: -2 to 16,777,215. For more information about color, see the RGB function in the PowerScript Reference.
TextSize	Integer	Specifies the size of the text in the control, in points. For backward compatibility, the size is stored as a negative number; for example, 10-point text size is stored as -10.
ThirdState	Boolean	Specifies whether the control is in the third state when the control has been defined to have three states. Values are: TRUE – Control is in third state. FALSE – Control is not in third state.
ThreeState	Boolean	Specifies whether the control has three states. Typically, CheckBox controls have only two states, such as on and off. Values are: TRUE – Control has three states. FALSE – Control does not have three states.
Underline	Boolean	Specifies whether the text in the control is underlined. Values are: TRUE – Text is underlined. FALSE – Text is not underlined.
Visible	Boolean	Specifies whether the control is visible. Values are: TRUE – Control is visible. FALSE – Control is not visible.
Weight	Integer	Specifies the stroke weight of the text in the control; for example, 400 for normal or 700 for bold.
Width	Integer	Specifies the width of the control, in PowerBuilder units.
X	Integer	Specifies the X position (the distance from the left edge of the window), in PowerBuilder units.
Y	Integer	Specifies the Y position (the distance from the top of the window), in PowerBuilder units.
