Is this possible to display each individual item so I can still check/uncheck
them using my below code, or can I use a different GeoExt/Ext container to
accomplish this? I need to keep the layers grouped because of performance but I
still need to be able to display each individual layer so that I can turn them
on/off. Is this possible? Any example/help immensely appreciated.
My layer group is declared as the following -
// Base Group Layers
var layer_Base = new OpenLayers.Layer.WMS("Base Layers",
"http://localhost/WebService/Request.aspx";,
{
layers:
['Bridge,Rural_Highway,Highway,Arterial,Street_Segment,
Street_Secondary_Segment, City_Boundary,
Hydrology,Neighbourhood_Area__clear_,Neighbourhood_Boundary,Major_Parks,Neighbourhood_Parks,Recreation_Sites,School_Sites,Linear_Parks,Section_Lines,Rural_Block_Line,Rural_Lot_Line'],
VERSION: "1.1.1",
transparent: true
},
{ isBaseLayer: false,
singleTile: true,
buffer: 4
}
);
Then I define my Treenode root and treepanel, and create a GeoExt
LayerContainer to load the layer into the root node. Can the layers above be
displayed as individual items with separate checkboxes somehow?
var layerRoot_Legend = new Ext.tree.TreeNode({
enableDD: true,
text: "All Legend Items",
loaded: true,
expanded: true
});
var layerTree_Legend = new Ext.tree.TreePanel({
title: '',
root: layerRoot_Legend,
enableDD: true,
applyLoader: true,
rootVisible: false
});
//Base layerList
layerList_Base = new GeoExt.tree.LayerContainer({
text: 'Base',
layerStore: mapPanel.layers,
leaf: false,
enableDD: true,
cls: 'rootnode',
singleClickExpand: true,
expanded: false,
checked: false,
listeners: {
'checkchange' : function(node, checked)
{
// If a parent node is unchecked, uncheck all the children
if (node.getUI().isChecked()) {
node.expand();
node.eachChild(function(child){
child.ui.toggleCheck(true);
});
}
if (!node.getUI().isChecked())
{
node.expand();
node.eachChild(function(child) {
child.ui.toggleCheck(false);
});
}
}
},
loader:
{
filter: function(record)
{
if (record.data.title == 'Base Layers')
return true;
}
}
});
layerRoot_Legend.appendChild(layerList_Base);
