KMessageWidget Class Reference
from PyKDE4.kdeui import *
Inherits: QFrame → QWidget → QObject
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 do not need the modalness of KMessageBox, consider using KMessageWidget instead.
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".
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.

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.
