Builders

  • Článek

Builders are tools that aid in setting properties of controls on a form. Unlike wizards, builders are reentrant, so you can reopen a builder on a particular control repeatedly.

Visual FoxPro includes a number of generic builders for many of the common form controls including grids, list boxes, combo boxes, check boxes, command groups, and option groups.

You can use builders for some controls, for forms, for formatting controls, and for creating referential integrity between database tables.

To build a control

  • From the Form Controls toolbar, choose the Builder Lock button. Each time you add a new control to a form, Visual FoxPro displays the appropriate builder.

    -or-

  • Select a control on the form, and choose the Builder button in the Properties window.

To use the Form Builder

  • From the Form menu, choose Quick Form.

When you have several controls on a form, you can format them all at the same time with the AutoFormat Builder.

To format several controls

  1. In the Form Designer, select controls.
  2. From the Form Designer Toolbar, choose the AutoFormat button.

When a builder is displayed, select the options for each tab and then choose OK to register the changes.
