DELPHI: Basics
 


Component Palette Toolbars

Components can be added to a form by clicking on the icon representing the component and then clicking on the form.

To place more than one similar component on the form keep in SHIFT before selecting the component and then release SHIFT and place the components on the form.

Components can be moved around with the mouse. They can also be grouped with the mouse and then copied (CTRL+C) and pasted (CTRL+V) as required. To remove a particular component - click on a component and press DELETE.

Properties of components can be changed using the Object Inspector.
