dragrect
Drag rectangles with mouse[finalRect] = dragrect(initialRect) [finalRect] = dragrect(initialRect,stepSize)
[finalRect] = dragrect(initialRect)
tracks one or more rectangles anywhere on the screen. The n-by-4 matrix rect defines the rectangles. Each row of rect must contain the initial rectangle position as [left bottom width height] values. dragrect returns the final position of the rectangles in finalRect.
[finalRect] = dragrect(initialRect,stepSize)
moves the rectangles in increments of STEPSIZE. The lower-left corner of the first rectangle is constrained to a grid of size STEPSIZE starting at the lower-left corner of the figure, and all other rectangles maintain their original offset from the first rectangle. [finalRect] = dragrect(...) returns the final positions of the rectangles when the mouse button is released. The default stepsize is 1.
dragrect returns immediately if a mouse button is not currently pressed. Use dragrect in a ButtonDownFcn, or from the commandline in conjunction with waitforbuttonpress, to ensure that the mouse button is down when dragrect is called. dragrect returns when you release the mouse button.
Drag a rectangle that is 50 pixels wide and 100 pixels in height.
waitforbuttonpress point1 = get(gcf,'CurrentPoint') % button down detected rect = [point1(1,1) point1(1,2) 50 100] [r2] = dragrect(rect)
