Time in milliseconds equivalent to the theoretical human moment, which can be used to determine whether how long to wait until the user should be informed of something, or can be used as the limit for how long something should wait before being automatically initiated. Some examples: - When the user types text in a search field, wait no longer than this duration after the user completes typing before starting the search - When loading data which would commonly arrive rapidly enough to not require interaction, wait this long before showing a spinner This might seem an arbitrary number, but given the psychological effect that three seconds seems to be what humans consider a moment (and in the case of waiting for something to happen, a moment is that time when you think "this is taking a bit long, isn't it?"), the idea is to postpone for just before such a conceptual moment. The reason for the two seconds, rather than three, is to function as a middle ground: Not long enough that the user would think that something has taken too long, for also not so fast as to happen too soon.

Plasma Framework
Foundational libraries, components, and tools of the Plasma workspaces
Introduction
The plasma framework provides the following:
- QML components
- A C++ library: libplasma
- Script engines
QML components
org.kde.plasma.core
Bindings for libplasma functionality, such as DataEngine and FrameSvg, see @ref core.
org.kde.plasma.components
Graphical components for common items such as buttons, lineedits, tabbars and so on. Compatible subset of the MeeGo components used on the N9, see @ref plasmacomponents.
org.kde.plasma.extras
Extra graphical components that extend org.kde.plasma.components but are not in the standard api, see @ref plasmaextracomponents.
org.kde.plasma.plasmoid
Attached properties for manipulating the current applet or containment, see @ref libplasmaquick
libplasma
This C++ library provides:
- rendering of SVG themes
- loading of files from a certain filesystem structure: packages
- data access through data engines
- loading of the plugin structure of the workspace: containments and applets
See @ref libplasma.
Script engines
Provides support to create applets or containments in various scripting languages.
