CheckBoxes

Description:

Checkboxes are used when you want to allow the user to select multiple options from a group of options. Checkboxes can also be used as a "toggle" to turn an option on or off. Checkboxes should always be placed inside of a Group Box.

Library Location:

Checkboxes are found in the Pickers category in the Xojo Library

Naming Conventions:

The prefix for a Checkbox is chk

Adding a Checkbox to your form:

• Place a Group Box onto your Form and give it a name (Remember to follow our naming conventions)
• Place a Checkbox inside of the Group Box
  
• In the Inspector, give the Checkbox a name (following our naming conventions) and add a caption
• Repeat this process until you have added all the Checkboxes you require
  

Accessing the Value a Checkbox

The Value property tells us if a checkbox is selected or not by returning a Boolean (True/False).

• If the Checkbox is selected, the Value property is True.
  
• If the Checkbox is not selected, the Value property is False.
  

By default, the value property is always set to false. You can change this in the Inspector as needed.

Using a Single If Statement to Determine the Value of a Checkbox

We can use an Single If Statement to test the value property of a Checkbox.

If (chkVanilla.Value = "True") then
 lstOut.AddRow("You added Vanilla Syrup to Your Coffee") 
 syrups = syrups + 1.25 
End If
