Detailed Description

When you need to communicate to the user that your application is busy with something you'll want to use a KBusyIndicatorWidget to display an spinnning indicator icon. The spinning animation can be stopped and started.

A way of using this widget is to combine it with a QLabel to construct a status line:

auto layout = new QHBoxLayout;
layout->addWidget(new KBusyIndicatorWidget);
layout->addWidget(new QLabel(QStringLiteral("Watering the flowers...")));

"KBusyIndicatorWidget with label"

The KBusyIndicatorWidget differs from the KPixmapSequenceWidget by animating a scaled icon instead of rendering a pixmap sequence. It supports multiple, semi-arbitrary sizes, with quality constrained only by the resolution of the available icons.
