[Users] Context menu on right click -GEOEXT

[Robert Buckley]

Hi Viola,

yes..it took a while for me too.

In my example the tree nodes hold the context menu...

In my example underneath, I have a context menu holding a "Zoom to Layer Extent" 
button and the Metadata window.

A test version is here http://maps.zgb.de/www/zgb_energie/geodatenportal.html

It could probably do with some tweaking though. For some reason the layers added 
dynamically to the tree could never be queried. I wrote many threads, but no-one 
was able to say why.


Anyway, hope it helps with your endeavors.




var layerTree = new Ext.tree.TreePanel({...etc


listeners: {
            contextmenu: function (node, e) {
                node.select();
                var c = node.getOwnerTree().contextMenu;
                c.contextNode = node;
                c.showAt(e.getXY())
            },
            scope: this
        },
        contextMenu: new Ext.menu.Menu({
            items: [{
                text: "Zoom to Layer Extent",
                icon: '../images/arrow_out.png',
                handler: function () {
                    var node = layerTree.getSelectionModel().getSelectedNode();
                    if (node && node.layer) {
                        this.map.zoomToExtent(node.layer.maxExtent)
                    }
                },
                scope: this
            },
            {

layerTree.getSelectionModel().getSelectedNode();

Betreff: Context menu on right click -GEOEXT

Hi Robert,
Stumbled upon your question regarding context menu on right click, I have 
searched the mailing lists but with no success. You asked the exact qusetion am 
trying to solve today. 
 http://www.mail-archive.com/users@geoext.org/msg01203.html:
I would like to achieve the same and am just wondering if you managed to get 
round this query.  Any advice/help will be highly appreciated as I have been at 
it for some days now without any success.
I qoute your question on the mailing list.
I would like to add a rightclick context menu to each layer in the layer tree 
which does the
>following.
>1. Changes opacity of the layer
>2. Offers metadata for that layer
>3. Offers a download choice for that layer
>4. Offers the ability to remove the layer

Looking forward to your reply.

Kind Regards,
Viola
