Presentación
WINDEV, WINDEV Mobile and WEBDEV allow you to manipulate a Check Box control programmatically. To do so, use the variable of the Check Box control in the code.
The variable of the Check Box control corresponds to the name of the Check Box control. This variable is an integer.
WINDEVAndroidiPhone/iPad Remark: Several WLanguage functions can be used to add, insert or delete options in a Check Box control.. For more details, see Check Box control functions.
Inicializar las diferentes opciones de una control Casilla de verificación
By default, no option is checked when a Check Box control is displayed.
To check an option of a Check Box control, you can use:
  • direct assignment:
    <Check Box control>[Option index] = 1

    <Check Box control>[Option index] = True
  • property Value:
    <Check Box control>[Option index].Value = True

    <Check Box control>[Option index].Value = 1
To clear an option of a Check Box control control, you can use:
  • direct assignment:
    <Check Box control>[Option index] = 0

    <Check Box control>[Option index] = False
  • the Value property.
    <Check Box control>[Option index].Value = 0

    <Check Box control>[Option index].Value = False
Remark: If the field is associated with an item in a data file, assignment is automatically performed using:
WINDEV If the undefined status of an option is supported ("Details" screen of the control description or TriState), the following syntax is used to initialize the option in the undefined status:
<Check Box control>[Option index] = -1

In WINDEV and WINDEV Mobile

To retrieve the value of an option, use the following syntax:
<Option_Value> = <Check Box control>[Option index]

In this case, <Option_Value> is a boolean set to:
  • True (1) if the box is checked,
  • False (0) if the box is unchecked.
  • WINDEVWindows -1 if the box is undefined (if this state is supported by the option).
Note If the field is associated with an item in a data file, the value entered is automatically retrieved using the <Window>.ToFile function. For more details, see Linking a Check Box control to an item.

The Caption property allows you to:
  • change the caption of the Check Box control:
    <Check Box control>.Caption = <Control caption>
  • change the caption for all the options of the Check Box control:

    <Check Box control>.Caption = <Option 1> + TAB + <Option 2> + TAB + <Option 3> ...
  • change the caption of an option:
    <Check Box control>[Option index].Caption = <New option caption>
