RADIOBUTTON Statement

Syntax:

  RADIOBUTTON text, id, x, y, width, height[, style]

The RADIOBUTTON statement creates a radio-button control. The control is a small circle that has the given text displayed to its right. The control highlights the circle and sends a message to its parent window when the user selects the button. The control removes the highlight and sends a message when the button is next selected. The RADIOBUTTON statement, which you can use only in a DIALOG or WINDOW statement, defines the text, identifier, dimensions, and attributes of a control window. The predefined class for this control is WC_BUTTON. If you do not specify a style, the default style is BS_RADIOBUTTON.

text

Specifies text that is displayed to the right of the control. This field must contain zero or more characters enclosed in double quotation marks. Character values must be in the range 1 through 255. If a double quotation mark is required in the text, you must include the double quotation mark twice. A tilde ( ~ ) character in the text indicates that the following character is used as a mnemonic character for the control. When the control is displayed, the tilde is not shown, but the mnemonic character is underlined. The user can choose the control by pressing the key corresponding to the underlined mnemonic character.

Specifies the control identifier. This value must be a signed integer in the range -32768 through 32767, an unsigned integer in the range of 1 through 65535, or a simple expression that evaluates to a value in these ranges.

Specifies the x-coordinate of the lower-left corner of the control. This value must be a signed integer in the range -32768 through 32767 or an expression consisting of integers and the addition (+) or subtraction (-) operator. The coordinate is assumed to be in dialog units and is relative to the origin of the dialog box, window, or control containing the specified control.

Specifies the y-coordinate of the lower-left corner of the control. This value must be a signed integer in the range -32768 through 32767 or an expression consisting of integers and the addition (+) or subtraction (-) operator. The coordinate is assumed to be in dialog units and is relative to the origin of the dialog box, window, or control containing the specified control.

Specifies the width of the control. This value must be an integer in the range 0 through 65535 or an expression consisting of integers and the addition (+) or subtraction (-) operator. The width is in n-character units.

Specifies the height of the control. This value must be an integer in the range 0 through 65535 or an expression consisting of integers and the addition (+) or subtraction (-) operator. The height is in 1/8-character units.

Specifies the control styles. This value can be a combination of the styles specified for WC_BUTTON. You can use the bitwise OR (|) operator to combine styles.

Example

This example creates a radio-button control that is labeled "Italic."
