After you place your components on your Designer, set their properties using the Object Inspector. By setting a component's properties, you can change the way a component appears and behaves in your application. Because properties appear during design time, you have more control over a component's properties and can easily modify them without having to write additional code.

To set component properties:

  1. On the Object Inspector, click the Properties tab.
  2. Set the component properties by entering values in the text box or through an editor.

Different types of properties have different editors:

  • Integer, float, and string properties can be edited directly in the property's text box.
  • Enumeration properties display a combo box instead of a text box, from which you can select an enumeration value.
  • Set properties can be expanded in the Object Inspector to display a list of options represented by check boxes. These check boxes can be toggled to either include to or exclude an option from the set.
  • Boolean properties display a check box that can be toggled. The checked state represents a value of True and an unchecked state-- a value of False.
  • Date properties can be edited directly or can display a date-time picker control that allows you to select the appropriate date easier.
  • Class properties can be expanded in the Object Inspector to display the properties of the exposed child object.
  • Properties that expect component references are displayed in red and show a combo box that allows you to select a compatible component that is present on the same Form or Data Module.
  • Custom properties display a [...] button at the right side of the text box. Pressing that button displays a custom editor dialog.
