1"""2This example demonstrates the use of pyqtgraph's dock widget system.3 4The dockarea system allows the design of user interfaces which can be rearranged by5the user at runtime. Docks can be moved, resized, stacked, and torn out of the main6window. This is similar in principle to the docking system built into Qt, but 7offers a more deterministic dock placement API (in Qt it is very difficult to 8programatically generate complex dock arrangements). Additionally, Qt's docks are 9designed to be used as small panels around the outer edge of a window. Pyqtgraph's 10docks were created with the notion that the entire window (or any portion of it) 11would consist of dockable components.12"""13 14import numpy as np15 16import pyqtgraph as pg17from pyqtgraph.console import ConsoleWidget18from pyqtgraph.dockarea.Dock import Dock19from pyqtgraph.dockarea.DockArea import DockArea20from pyqtgraph.Qt import QtWidgets21 22app = pg.mkQApp("DockArea Example")23win = QtWidgets.QMainWindow()24area = DockArea()25win.setCentralWidget(area)26win.resize(1000,500)27win.setWindowTitle('pyqtgraph example: dockarea')28 29## Create docks, place them into the window one at a time.30## Note that size arguments are only a suggestion; docks will still have to31## fill the entire dock area and obey the limits of their internal widgets.32d1 = Dock("Dock1", size=(1, 1))     ## give this dock the minimum possible size33d2 = Dock("Dock2 - Console", size=(500,300), closable=True)34d3 = Dock("Dock3", size=(500,400))35d4 = Dock("Dock4 (tabbed) - Plot", size=(500,200))36d5 = Dock("Dock5 - Image", size=(500,200))37d6 = Dock("Dock6 (tabbed) - Plot", size=(500,200))38area.addDock(d1, 'left')      ## place d1 at left edge of dock area (it will fill the whole space since there are no other docks yet)39area.addDock(d2, 'right')     ## place d2 at right edge of dock area40area.addDock(d3, 'bottom', d1)## place d3 at bottom edge of d141area.addDock(d4, 'right')     ## place d4 at right edge of dock area42area.addDock(d5, 'left', d1)  ## place d5 at left edge of d143area.addDock(d6, 'top', d4)   ## place d6 at top edge of d444 45## Test ability to move docks programatically after they have been placed46area.moveDock(d4, 'top', d2)     ## move d4 to top edge of d247area.moveDock(d6, 'above', d4)   ## move d6 to stack on top of d448area.moveDock(d5, 'top', d2)     ## move d5 to top edge of d249 50 51## Add widgets into each dock52 53## first dock gets save/restore buttons54w1 = pg.LayoutWidget()55label = QtWidgets.QLabel(""" -- DockArea Example -- 56This window has 6 Dock widgets in it.
