TCL/TK Tips for DemDraw

All but one of DemDraw's features can be used by clicking the left mouse button.
To create a vertex, click once on the canvas with a vertex tool.
To create an edge, click and hold down the mouse from a starting vertex to an ending vertex. Release the mouse when the ending vertex is highlighted.
To create an edge that starts and ends at the same vertex, click once on the vertex with an edge tool. Note: these type of edges can only have 3 bend points... no more, no less.
To add bend nodes, double click on an edge with the Selection tool. Move the nodes via the red bubbles.
To delete a bend node, double RIGHT click on the red bubble.
Rename labels by clicking on them (or the object they are labeling) with the Rename tool.
Delete an object by clicking on them or their labels. Note: Deleting a vertex will delete all connecting edges.
Move verities, vertex labels, or edge labels with the Selection tool. (Click and drag.)
To save any file (PostScript, CD's, DemDraw files) the file name must be unique to the directory you wish save it to.
To open a file, double click on the name or type it in the text field and hit return.
