Hi Jukka, > The measurement tool inserts measurements into a special layer and if that > layer is made selectable and editable it is possible to edit the geometries > and all the areas, lengths, and segment lengths are updated in real time. It > seems even to be possible to digitize a hole into a measurement polygon and > perimeter grows while the area is degreasing. Do you know you can simulate this with Edit Attribute > Attribute Calculator (Beanshell) to add a column with area, you just have to pick the example on the right side of the dialog You can have "dynamic" behaviour by checking dynamic option. > I wonder if this tool could be re-used for showing info about existing lines > and polygons which are on normal layers. Usage could be like Select features > - Right click - Show distances and areas. It could be implemented by copying > the selected geometry into measument layer but it might also be fancy to be > able to edit the features with the Show measures -option on. You also have the tool View > Display attributes on the map which displays perimeter/area as tooltips by just overflying features. I just noticed that it does not work well with geographic coordinates as it only display a few decimals
