If you would like to change the L&F take into account that PropertiesDialog and PropertiesDialog2 change the L&F setting upon invocation (you can e.g. change the L&F after the dialog).

Structure describing sets of media formats

Caps (capabilities) are lightweight objects describing media types. They are composed of an array of {@link Structure}.

Caps are exposed on {@link PadTemplate} to describe all possible types agiven pad can handle. They are also stored in the {@link Registry} along witha description of the {@link Element}.

Caps are exposed on the element pads using the {@link Pad#getCaps} method. This method describes the possible types that the pad can handle or produce at runtime.

Caps are also attached to buffers to describe the content of the data pointed to by the buffer with {@link Buffer#setCaps}. Caps attached to a {@link Buffer} allow for format negotiation upstream and downstream.

A Caps can be constructed with the following code fragment:

Caps caps = Caps.fromString("video/x-raw-rgb, bpp=32, depth=24, width=640, height=480");

A Caps is fixed when it has no properties with ranges or lists. Use {@link #isFixed} to test for fixed caps. Only fixed caps can beset on a {@link Pad} or {@link Buffer}.

Various methods exist to work with the media types such as subtracting or intersecting. @see Structure
