Move Item is used to re-position items on the drawing
canvas. When this tool is selected, the cursor changes shape to
indicate when the mouse is positioned over a movable item. Use the
mouse to select and drag the target item from its current position to
the desired location on the canvas.
Items that can be moved using this tool include nodes,
edge labels, and edge anchor points. For each of these items, details
differ on the boundaries accepted for selecting an item, and the rules
used to govern item positioning:
- Selecting and Positioning Nodes. Nodes may be
selected by pressing the mouse button anywhere in the boundary of the
drawn node. The selected node can then be dragged to any position on
the drawing canvas, without restriction.
- Selecting and Positioning Edge Labels. The position of an edge
label is tied to the location of the anchor point for the associated
edge. An edge label is selected by pressing the mouse button anywhere
in the boundary of the currently displayed label. If the edge
data field currently displayed is empty for a particular edge, then
the associated edge label cannot be re-positioned. In this case,
temporarily change the displayed data to Edge ID (or some
non-empty data field) before attempting to move the edge label. The
edge label can then be positioned to the north (centered), south
(centered), east (left aligned), or west (right aligned) of the edge
anchor point.
- Selecting and Positioning Edge Anchor Points. Edge anchor
points are used to control the shape of the drawn edge and the general
location of the associated edge label. An edge anchor point is
selected by pressing the mouse button anywhere in the boundaries of
the box region drawn at the current anchor point location. The
selected edge anchor point can then be dragged to any position on the
drawing canvas, without restriction. To allow edge anchor point to be
automatically calculated, click the edge anchor point while holding
the shift key.
