Detailed Description

A KDialogBase with predefined main widget.

As a KDialogBase it uses your application wide settings for KDialogBase objects (base frame tiles, main frame tiles etc). To use it, simply create a KAboutDialog object, set all (or some) of its properties and show it. Do not derive it to create your own about dialog until you need some cool features that are unsupported and you have contacted me to add them.

The dialog can be created using two different constructors. The difference between these constructors is the available components that can be used to build the contents of the dialog. The first (Constructor I) provides a number of easy to use methods. Basically it allows you to add the components of choice, and the components are placed in a predefined layout. You do not have to plan the layout. Everything is taken care of.

The second constructor (Constructor II) works in quite the same manner as the first, but you have better control on where the components are postioned in the layout and you have access to an extended number of components you can install such as titles, product information, a tabbed pages (where you can display rich text with url links) and a person (developer) information field. The "About KDE" dialog box is created with Constructor II.

For the derived features, see the basic class KDialogBase.

The extended constructor.

(Constructor II).

Add components with the methods: setTitle(), setImage(), setImageBackgroundColor(), setImageFrame(), setProduct(), addTextPage(), addContainerPage(), addContainer(), or addPage().

Parameters:
