Controlling Form Behavior

JavaScript Editor js editor     Web development 



Main Page

When you are designing a form in the Form Designer, the form is live: except for setting the Visible property to false (.F.), visual and behavioral changes you make are immediately reflected in the form. If you set the WindowState property to 1 – Minimized or 2 – Maximized, the form in the Form Designer immediately reflects this setting. If you set the Movable property to false (.F.), a user will not be able to move the form at run time and you won't be able to move the form at design time either. You might want to design the functionality of your form and add all the appropriate controls before you set some of the properties that determine form behavior.

The following form properties are commonly set at design time to define the appearance and behavior of the form.

Property Description Default

AlwaysOnTop

Controls whether a form is always on top of other open windows.

False (.F.)

AutoCenter

Controls whether the form is automatically centered in the main Visual FoxPro window or on the desktop when the form is initialized.

False (.F.)

BackColor

Determines the color of the form window.

255,255,255

BorderStyle

Controls whether the form has no border, a single-line border, a double-wide border, or a system border. If the BorderStyle is 3 - System, the user will be able to resize the form.

Determines the text displayed in the title bar of the form.
