navdata_pi

Is compatible with OpenCPN 5.0.0 (and the current master)

This new version has a completely new design.

The purpose is to show navigation information about a selected intermediate route point in the current active route. This can be useful if you want to keep an eye on a intermediate point, not visible in the ocpn console,for example a point marking a difficult cap, or an entry in a channel with strong current.

Select-able point: Any point after the current active point. This means that all points from the start to the current active point(included) are not select-able.

At start the plugin toolbar icon is in waiting state, the plugin is active but the point selection is deactivated.

To use the plugin, you have to click on the icon to activate the selection. The icon shows you that the selection is activated

Verify you have activated your route.

Now, you can left click on any select-able point of this route. As a result, you will see a green circle blinking around it and a window looking like the ocpn console will be opened. This window shows RNG (distance), TTG (time to go) and ETA (estimated time of arrival) to this selected point. As in the ocpn console, you can toggle TTG and ETA computed with SOG or VMG by left click on inside. This window can be moved and its new position is memorized.

At any moment, you can select another select-able point, but only mean to cancel any selection and close the window is to left click on a no select-able point (for example the current active point).

If you want to lock your selection, click on the plugin icon to deactivate selection.

In any case, when this selected point become the current active point, the selection is canceled and the window is closed.

There is no setting. The plugin uses ocpn configuration parameters. In general, these parameters apply in live, but it could be necessary to close and reopen ocpn for some changes (language …).

For those who had a look at the previous version, there is no longer neither grid window nor "Trip" data.
