This example demonstrates the use of pyqtgraph's dock widget system.
|
||||
|
||||
The dockarea system allows the design of user interfaces which can be rearranged by
|
||||
the user at runtime. Docks can be moved, resized, stacked, and torn out of the main
|
||||
window. This is similar in principle to the docking system built into Qt, but
|
||||
offers a more deterministic dock placement API (in Qt it is very difficult to
|
||||
programatically generate complex dock arrangements). Additionally, Qt's docks are
|
||||
designed to be used as small panels around the outer edge of a window. Pyqtgraph's
|
||||
docks were created with the notion that the entire window (or any portion of it)
|
||||
would consist of dockable components.
