Detailed Description

Easy message dialog box.

Provides convenience functions for some i18n'ed standard dialogs, as well as audible notification via KNotification

The text in message boxes is wrapped automatically. The text may either be plaintext or richtext. If the text is plaintext, a newline-character may be used to indicate the end of a paragraph.

KDE 4 Porting Guide:

Where applicable, the static functions now take an additional argument to specify the cancel button. Since a default argument is provided, this will affect your code only, if you specified dontAskAgainName and/or options. In those cases, adding an additional parameter KStandardGuiItem::cancel() leads to the old behavior. The following functions are affected (omitting function arguments in the list): questionYesNoCancel(), questionYesNoCancelWId(), warningContinueCancel(), warningContinueCancelWId(), warningContinueCancelList(), warningContinueCancelListWId(), warningYesNoCancel(), warningYesNoCancelWId(), warningYesNoCancelList(), warningYesNoCancelListWId(), messageBox(), messageBoxWId().

Member Function Documentation

void KMessageBox::about	(	QWidget *	parent,
		const QString &	text,
		const QString &	caption = QString(),
		Options	options = Notify
	)			[static]

Display an "About" dialog.

Parameters:

	parent	If parent is 0, then the message box becomes an application-global modal dialog box. If parent is a widget, the message box becomes modal relative to parent.
	text	Message string.
	caption	Message box title. The application name is added to the title. The default title is i18n("About \<appname\>").
	options	see Options

Your program wants to show some general information about the application like the authors's names and email addresses.

The default button is "&OK".

NOTE: The ok button will always have the i18n'ed text '&OK'.

Definition at line 1030 of file kmessagebox.cpp.

int KMessageBox::createKMessageBox	(	KDialog *	dialog,
		const QIcon &	icon,
		const QString &	text,
		const QStringList &	strlist,
		const QString &	ask,
		bool *	checkboxReturn,
		Options	options,
		const QString &	details = QString(),
		QMessageBox::Icon	notifyType = QMessageBox::Information
	)			[static]

Create content and layout of a standard dialog.

Parameters:

	dialog	The parent dialog base
	icon	A QPixmap containing the icon to be displayed in the dialog next to the text.
	text	Message string.
	strlist	List of strings to be written in the listbox. If the list is empty, it doesn't show any listbox
	ask	The text of the checkbox. If empty none will be shown.

	options	see Options
	details	Detailed message string.

Returns:

A KDialog button code, not a KMessageBox button code, based on the buttonmask given to the constructor of the dialog (ie. will return KDialog::Yes [256] instead of KMessageBox::Yes [3]). Will return KMessageBox::Cancel if the message box is queued for display instead of exec()ed immediately or if the option NoExec is set.

Note:

Unless NoExec is used, the dialog that is passed in is deleted by this function. Do not delete it yourself.

void KMessageBox::detailedError	(	QWidget *	parent,

		const QString &	details,
		const QString &	caption = QString(),
		Options	options = Notify
	)			[static]

Displays an "Error" dialog with a "Details >>" button.

Parameters:

	parent	If parent is 0, then the message box becomes an application-global modal dialog box. If parent is a widget, the message box becomes modal relative to parent.
	text	Message string.
	details	Detailed message string.
	caption	Message box title. The application name is added to the title. The default title is i18n("Error").
	options	see Options

Your program messed up and now it's time to inform the user. To be used for important things like "Sorry, I deleted your hard disk."

The details message can conatin additional information about the problem and can be shown on request to advanced/interested users.

If your program detects the action specified by the user is somehow not allowed, this should never be reported with error(). Use sorry() instead to explain to the user that this action is not allowed.

The default button is "&OK". Pressing "Esc" selects the OK-button.

NOTE: The OK button will always have the i18n'ed text '&OK'.

Definition at line 836 of file kmessagebox.cpp.

	)			[static]

This function accepts the window id of the parent window, instead of QWidget*.

It should be used only when necessary.
