I am new to GeoExt and am struggling to figure out how to add a GeoExt.tree.panel to a Ext.tab.Panel. Here is what I have in brief:
Ext.application({
name: 'Custom Map',
launch: function() {
//.
//.
//. a bunch of code up here including the MapPanel!!
//.
//.
var store = Ext.create('Ext.data.TreeStore', {
model: 'GeoExt.data.LayerTreeModel',
root: {
plugins: [{
ptype: "gx_layercontainer",
loader: {
createNode: function(attr) {
// add a WMS legend to each node created
attr.component = {
xtype: "gx_wmslegend",
layerRecord:
mapPanel.layers.getByLayer(attr.layer),
showTitle: false,
// custom class for css positioning
// see tree-legend.html
cls: "legend"
};
return
GeoExt.tree.LayerLoader.prototype.createNode.call(this, attr);
}
}
}]
}
});
var tabPanel = Ext.create('Ext.tab.Panel', {
region: "west",
title: "TOC",
collapsible: true,
collapseMode: "mini",
split: true,
tabPosition: "bottom",
plain: true,
border: true,
items: [{
xtype: "treepanel",
//<--I have tried gx_treepanel here, but to no avail (get errors)
store: store,
title: "Layers",
width: 250,
autoScroll: true,
rootVisible: false,
bodyPadding: "10,
0",
lines: false,
viewConfig: {
plugins: [{
ptype: 'treeviewdragdrop',
appendOnly: false
}]
}
}, {
title: "Legend",
bodyPadding: 10,
width: 250,
html: "This is
where the Legend goes<br>" + //This is temp placeholder code for now
"This is where the
Legend goes<br>" +
"This is where the
Legend goes<br>" +
"This is where the
Legend goes<br>" +
"This is where the
Legend goes<br>"
}]
});
Ext.create('Ext.Viewport', {
layout: "fit",
hideBorders: true,
items: {
layout: "border",
//Don't know if I
really need deferredRender
deferredRender:
false,
items: [
mapPanel, tabPanel //, toolbar
]
}
});
}
});
Under the var tabPanel (see above), I have the "items" config that contains an
xtype of treepanel right now. This 'sort of' works, but not as expected. I
have also tried an gx_treepanel here, but this gives all kinds of errors and
really doesn't work as expected.
Any advice would be appreciated!
