Syntax
[finalrect] = dragrect(initialrect) [finalrect] = dragrect(initialrect,stepsize)
Description
[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.
Remarks
dragrect returns immediately if a mouse button is not currently pressed. Use dragrect in a ButtonDownFcn, or from the command line in conjunction with waitforbuttonpress to ensure that the mouse button is down when dragrect is called. dragrect returns when you release the mouse button.
Example
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)
