GridPainter

An instance of the GridPainter plugin draws a grid with the configured dimensions onto the screen. One can configure the number of rows and columns independently or associate one to the other with a click on the button with the chain. If they are associated, then both will have the same value automatically.

It is the same with the width and the height of a grid element. The preference page for an instance of the GridPainter plugin is shown in the image below. Since a GridPainter instance does not compute any packets, no semantic type can be set. To make the grid visible, both active and visible must be set. If one of those is not set, the is not being displayed.

The grid corresponding to the configuration above can be seen in the image below.

A GridPainter instance does not support metric. It simply draws a grid at the specified position and the with the specified size on the drawing area. Thus an instance can be active independently from the type of the active NodePositioner. If a SpringEmbedderPositioner instance is active, one must ignore the metric units on the preference page.
