## 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.

enum LayoutType { AbtPlain = 0x0001, AbtTabbed = 0x0002, AbtTitle = 0x0004, AbtImageLeft = 0x0008, AbtImageRight = 0x0010, AbtImageOnly = 0x0020, AbtProduct = 0x0040, AbtKDEStandard = AbtTabbed|AbtTitle|AbtImageLeft, AbtAppStandard = AbtTabbed|AbtTitle|AbtProduct, AbtImageAndTitle = AbtPlain|AbtTitle|AbtImageOnly } | ### LayoutType

Layout formats.

KAboutDialog ( QWidget *parent=0, const char *name=0, bool modal=true ) | ### KAboutDialog

The standard Qt constructor (Constructor I).

Add components with the following methods: setLogo(), setAuthor(), setMaintainer(), addContributor(), or setVersion(). The dialog will be laid out automatically.

KAboutDialog ( int dialogLayout, const QString &caption, int buttonMask, ButtonCode defaultButton, QWidget *parent=0, const char *name=0, bool modal=false, bool separator = false, const QString &user1 = QString::null, const QString &user2 = QString::null, const QString &user3 = QString::null ) | ### KAboutDialog

The extended constructor. (Constructor II).

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

Parameters:

dialogLayout | Use a mask of LayoutType flags.
caption | The dialog caption. The text you specify is prepended by i18n("About").
buttonMask | Specifies what buttons will be visible.
defaultButton | Specifies what button will be marked as the default.
parent | Parent of the dialog.
name | Dialog name (for internal use only)
modal | Sets dialog modality. If false, the rest of the program interface (other dialogs, for example) is accessible while the dialog is open.
separator | If true, a separator line is drawn between the action buttons an the main widget.
user1 | User button1 text.
user2 | User button2 text.
user3 | User button3 text.

void adjust () | ### adjust

Adjust the dialog.

You can call this method after you have set up all the contents but it is not required. It is done automatically when show() is executed.

void show ( void ) | ### show

[virtual]

Make a modeless (modal = false in constructor) dialog visible.

If you reimplement this method make sure you run it in the new method (e.g., show()). Reimplemented from KDialogBase.

Reimplemented from QDialog.

void show ( QWidget *centerParent ) | ### show

[virtual]

Make a modless (modal = false in constructor) dialog visible.

If you reimplmement this method make sure you run it in the new method (i.e., show( parent )).

Parameters:

centerParent | Center the dialog with respect to this widget.

Reimplemented from QDialog.

void setTitle ( const QString &title ) | ### setTitle

(Constructor II only) Set a title (not caption) in the uppermost area of the dialog

Parameters:

title | Title string.

void setImage ( const QString &fileName ) | ### setImage

(Constructor II only) Define an image to be shown in the dialog. The position is dependent on the `dialogLayout` in the constructor

Parameters:

fileName | Path to image file.

void setImageBackgroundColor ( const QColor &color ) | ### setImageBackgroundColor

(Constructor II only) The image has a minimum size, but is centered within an area if the dialog box is enlarged by the user. You set the background color of the area with this method.

Parameters:

color | Background color.

void setImageFrame ( bool state ) | ### setImageFrame

(Constructor II only) Enable or disable a frame around the image. The frame is, by default, enabled in the constructor

Parameters:

state | A value of `true` enables the frame

void setProduct ( const QString &appName, const QString &version, const QString &author, const QString &year ) | ### setProduct

(Constructor II only) Print the application name, KDE version, author, a copyright sign and a year string. To the left of the text the standard application icon is displayed.

Parameters:

appName | The application name.
version | Application version.
author | One or more authors.
year | A string telling when the application was made.

QFrame * addTextPage ( const QString &title, const QString &text, bool richText=false, int numLines=10 ) | ### addTextPage

(Constructor II only) Add a text page to a tab box. The text can be regular text or rich text. The rich text can contain URLs and mail links.

Parameters:

title | Tab name.
text | The text to display.
richText | Set this to `true` if 'text' is rich text.
numLines | The text area height will be adjusted so that this is the minimum number of lines of text that are visible.

Returns: The frame that contains the page.

QFrame * addLicensePage ( const QString &title, const QString &text, int numLines=10 ) | ### addLicensePage

(Constructor II only) Add a license page to a tab box.

Parameters:

title | Tab name.
text | The text to display.
numLines | The text area height will be adjusted so that this is the minimum number of lines of text that are visible.

Returns: The frame that contains the page.

KAboutContainer * addContainerPage ( const QString &title, int childAlignment = AlignCenter, int innerAlignment = AlignCenter ) | ### addContainerPage

(Constructor II only) Adds a container to a tab box. You can add text and images to a container.

Parameters:

title | Tab name.
childAlignment | Specifies how the children of the container are aligned with respect to the container.
innerAlignment | Specifies how the children are aligned with respect to each other.

Returns: The new container.

KAboutContainer * addScrolledContainerPage ( const QString &title, int childAlignment = AlignCenter, int innerAlignment = AlignCenter ) | ### addScrolledContainerPage

(Constructor II only) Adds a container inside a QScrollView to a tab box. You can add text and images to a container.

Parameters:

title | Tab name.
childAlignment | Specifies how the children of the container are aligned with respect to the container.
