TextBoxes

Description:

Textboxes can be used for either Input or Output on your form. When you use a TextBox for input you must cast it from a string to the appropriate data type before using it in your code.

When using a textbox for output, you must cast any variables to a string data type.

Library Location:

Textboxes (aka Text Fields) are found in the Inputs category in the Xojo Library

Naming Conventions:

The prefix for a TextBox is txt

Adding a TextBox to your form:

• Place a TextBox 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, modify the following Properties:
  • Name (ie: txtHello)
  • Modify the appearance and size (user’s preference)
  • Modify the font (user’s preference)
