Detailed Description

A widget to provide feedback or propose opportunistic interactions.

KMessageWidget can be used to provide inline positive or negative feedback, or to implement opportunistic interactions.

As a feedback widget, KMessageWidget provides a less intrusive alternative to "OK Only" message boxes. If you want to avoid a modal KMessageBox, consider using KMessageWidget instead.

Examples of KMessageWidget look as follows, all of them having an icon set with setIcon(), and the first three show a close button:

KMessageWidget with different message types

Negative feedback

The KMessageWidget can be used as a secondary indicator of failure: the first indicator is usually the fact the action the user expected to happen did not happen.

Example: User fills a form, clicks "Submit".

Expected feedback: form closes
First indicator of failure: form stays there
Second indicator of failure: a KMessageWidget appears on top of the form, explaining the error condition

When used to provide negative feedback, KMessageWidget should be placed close to its context. In the case of a form, it should appear on top of the form entries.

KMessageWidget should get inserted in the existing layout. Space should not be reserved for it, otherwise it becomes "dead space", ignored by the user. KMessageWidget should also not appear as an overlay to prevent blocking access to elements the user needs to interact with to fix the failure.

Positive feedback

KMessageWidget can be used for positive feedback but it shouldn't be overused. It is often enough to provide feedback by simply showing the results of an action.

Examples of acceptable uses:

Confirm success of "critical" transactions
Indicate completion of background tasks

Example of unadapted uses:

Indicate successful saving of a file
Indicate a file has been successfully removed

Opportunistic interaction

Opportunistic interaction is the situation where the application suggests to the user an action he could be interested in perform, either based on an action the user just triggered or an event which the application noticed.

Example of acceptable uses:

A browser can propose remembering a recently entered password
A music collection can propose ripping a CD which just got inserted
A chat application may notify the user a "special friend" just connected

Member Enumeration Documentation

◆ MessageType

enum KMessageWidget::MessageType

Available message types.

The background colors are chosen depending on the message type.

Enumerator
Positive	Positive message type.
Information	Information message type.
Warning	Warning message type.
Error	Error message type.

Definition at line 103 of file kmessagewidget.h.

◆ Position

enum KMessageWidget::Position

Position of the KMessageWidget.

This will update the look of the KMessageWidget to be appropriate to the position.

Since: 6.0

Enumerator
Inline	The message widget is display inside the content.
Header	The message widget is displayed as header.
Footer	The message widget is displayed as footer.

Definition at line 237 of file kmessagewidget.cpp.

◆ KMessageWidget() [2/2]

KMessageWidget::KMessageWidget	(	const QString &	text,
		QWidget *	parent = nullptr )

explicit

Constructs a KMessageWidget with the specified parent and contents text.

◆ ~KMessageWidget()

KMessageWidget::~KMessageWidget ( )

overridedefault

Destructor.

Member Function Documentation

◆ addAction()

void KMessageWidget::addAction ( QAction * action )

Add action to the message widget.

For each action a button is added to the message widget in the order the actions were added.

Parameters

action the action to add

See also: removeAction(), QWidget::actions()

Definition at line 436 of file kmessagewidget.cpp.

◆ animatedHide

void KMessageWidget::animatedHide ( )

slot

Hide the widget using an animation.

Definition at line 487 of file kmessagewidget.cpp.

◆ animatedShow

void KMessageWidget::animatedShow ( )

slot

Show the widget using an animation.

Definition at line 457 of file kmessagewidget.cpp.

◆ clearActions()

void KMessageWidget::clearActions ( )

Clears all actions from the message widget.

See also: KMessageWidget::MessageType, addAction() and removeAction()

Since: 5.100

Definition at line 448 of file kmessagewidget.cpp.

◆ event()

bool KMessageWidget::event ( QEvent * event )

overrideprotectedvirtual

Reimplemented from QFrame.

Definition at line 313 of file kmessagewidget.cpp.

◆ heightForWidth()

int KMessageWidget::heightForWidth ( int width ) const

overridevirtual

Returns the required height for width.

Parameters

width the width in pixels

Reimplemented from QWidget.

Definition at line 351 of file kmessagewidget.cpp.

◆ hideAnimationFinished

void KMessageWidget::hideAnimationFinished ( )

signal
