Popup-Box Component for Delphi
Version 2.0

1. Introduction

The PopupBox-Component is a component for Borlands Delphi and a replacement for the ComboBox 
with style csDropDownList. Because I am altogether dissatisfied with the Combobox, it's look 
and functionality, I made the decision to write my own component. And here it is!
The PopupBox looks like an Edit- or Memofield, but it is not editable. If you click on it, a 
list opens up. You may select one of the list-entries by an other Mouseclick or by pressing 
the RETURN key. This entry will then become the current Text of the PopupBox-field. Optional 
the next window-control can be automatically focused. But if you don't like the way, PopupBox 
handles RETURN / MouseClicks, you can simply control this behaviour in Delphis Objectinspector 
with the properties GoAwayOnClick and GoAwayOnReturn. The PopupBox then will stay open until 
you move to an other window-control (by pressing the TAB key or clicking at an other field).
I guess it's a little bit difficult to understand how it works, but I think it's clear at once 
if you see the SAMPLE program, included in this package. Before you can compile and run this 
sample program you must install the PopupBox as a Delphi component. Look at section 3 - 
Installation. PopupBox has a many settings, which can change it's style. They are listed at 
section 5 - PopupBox properties .

The PopupBox is much more resource friendly than Delphi's ComboBox. Every ComboBox in your 
application creates a (hidden) listwindow, which is only unhidden, when the combolist is shown. 
These hidden windows let go down your rare windows system resources. But the PopupBox creates 
only ONE listwindow. And the listwindow exists only as long as the list is shown. It will be 
destroyed as soon as the list is closed.

Using conditions
I am offering a *free* Trial-Run component. This free component has the full functionality of 
the registered version, but can run only when Delphi is also running on the PC. That should 
make it easy for Delphi programmers to try this native VCL component (without time limitations).
 To deliver an application using this component, you must purchase the applicable registered 
product. If you would like to order/register PopupBox, you can obtain two different versions:

PopupBox v2.0 without source code:	$19.00  (or 28,00 DM)
PopupBox v2.0 including full source code:	$38.00  (or 49,00 DM)

I will e-mail you immediately the latest version, so don't forget to tell me your e-mail 
address!
