<p>TForm represents a standard application window (form).
When you create forms in the Form designer at design time, they are implemented as descendants of TForm. Forms can represent the application’s main window, or dialog boxes, or MDI children. A form can contain other objects, such as TButton, TCheckBox, and TComboBox objects.
Examples of forms include TLoginDialog and TPasswordDialog objects.</p>

<dd><p>Specifies the action associated with the control.
Action is the action object that is associated with the control. Actions allow an application to centralize the response to user commands. When a control is associated with an action, the action determines the appropriate properties and events of the control (such as whether the control is enabled or how it responds to an OnClick event).
To create actions at design time, place an action list component on a form or data module. Double-click the action list to bring up the action list editor. Add actions in the editor using its context menu. Once the actions have been added using the Action List editor, they appear in the drop-down list for the Action property in the Object Inspector.</p>

Use ActiveControl to get or set the control that has focus on the form. Only one control can have focus at a given time in an application.
If the form does not have focus, ActiveControl is the control on the form that will receive focus when the form receives focus.</p>
<p>Note: When focus shifts to another control, ActiveControl is updated before the OnExit event occurs.</p>

<dd><p>Determines how the control aligns within its container (parent control).
Use Align to align a control to the top, bottom, left, or right of a form or panel and have it remain there even if the size of the form, panel, or component that contains the control changes. When the parent is resized, an aligned control also resizes so that it continues to span the top, bottom, left, or right edge of the parent.
For example, to use a panel component with various controls on it as a tool palette, change the panel’s Align value to alLeft. The value of alLeft for the Align property of the panel guarantees that the tool palette remains on the left side of the form and always equals the client height of the form.
The default value of Align is alNone, which means a control remains where it is positioned on a form or panel.</p>
<p>Tip: If Align is set to alClient, the control fills the entire client area so that it is impossible to select the parent form by clicking it. In this case, select the parent by selecting the control on the form and pressing ESC, or by using the Object Inspector.
