TSetup v3.00 Components
TSetup v3.00 is in its beta program. Not all components have been finished.
Here is list of current components and a list of future components (I hope).
If you have any ideas or suggestions, please let me know.
Most TSetup components are edited via component editors. Some components have
more than one component editor. All components have events that are triggered upon
execution and most have have events that are triggered upon basic button presses (Next,
Previous, Cancel). Most of the components also have a Picture property, which allows
the programmer to specify a different picture that will be displayed in the dialog box.
Components are "chained" together into a single strand using the NextPage
property. Individual components can be skipped as necessary by setting their Enabled
property to False.

 TSetupFileCopy |
Although this component does the least amount
visually, this component does the bulk of work of the installation. This component

from an archive if necessary, requesting a different disk if necessary, downloading file
from the Internet if necessary, and so on. Here are some additional features:

elaborate license or copyright. |
TSetupRegistration |
This component will gather any combination of
three pieces of information: user's name, user's company, user's registration code.
The programmer can select which ones should be requested; properties can also control
which items are required before the install can continue. Events allow the
programmer to make advanced decisions about whether or not the installation should
continue. |
