MeasureToolbar: New toolbar to measure length, areas and shapes.

[jorix]

To measure with OpenLayers is necessary use measure control, but work with it requires some API user effort. I think this ticket simplify API use to measure.

MeasureToolbar is a toolbar to measure. It is easy to use for end user. It displays a toolbar with buttons and the measure value.

Characterized by:

• Show the data in a div into the Panel, the developer may forget to make a div for this.
• Shows the area and perimeter length simultaneously for polygons.
• Allows measurement of features in vectors layers and also reports the name of the feature.

Other features:

• Measures are not rounded to a fixed number of decimals, are showing only the significant digits (default 4, shows for example: 134.2 m, 3.437km or 453,500 km)
• Can copy the text of the measure obtained. Some mouse events on the div of measure value are disabled.
• The vector layers are automatically detected to measure features option, see measureLayers option.
• The buttons have title (currently only in English, Spanish and Catalan [my native language])

---

This require ticket #2501. They are necessary for to give length and area simultaneously, and also to allow for measuring a geometry from a vector layer.

Also uses the #2508, but is not required to work.

For better appearance, in non quirks mode on can add this in CSS:

.olControlMeasureToolbar {width: auto;}

NOTE: The attached patch also contains an example of using.

Work ok in IE8, FF35 and CH4.

Looks great. This would make a perfect addin. For going into trunk, it is too much focused on a specific use case. Please have a look at Addins to learn how to contribute an addin.

I forgot, missing the icons, an extension of "editing_tool_bar.png" with and good transparency in the corners.

Your proposal to addins passing was not exactly my purpose. I think in OL missing controls in the trunk to facilitate work to basic users. For example to use Popups, Measure or SelectFeature requires considerable effort. And yet there are controls on the trunk that are nothing more than examples of use as EditingToolbar, NavToolbar.

My approach has been to grouping all this into a toolbar and has all these components working together. I named it MultiToolbar and MeasureToolbar is only one component of it.

In the same, I have also proposed the tickets #2507, #2501 and #2508, please review it.

Well, if trunk is not possible: when I have finished the MultiToolbar I put entire it in a proposal for addins. (today I ask access to sandbox to PSC).

Thanks ahocevar.

I'm not going to work in this direction by using "lib" in this way.
