After v5.5.5 there was this change:
Fixed: ClientLoading event was being fired too late, some functions like fileManager.onViewRefresh are registered as event handlers to internal components so even you override them later the components still referred to the old function reference, so Ext.override was not working. From now on ClientLoading will now fire at the start of initComponent and ClientLoaded at the end of initComponent. ClientLoading should be used for Ext.override calls, ClientLoaded should be called for adding actions, UI elements.
So for addTab to work, you should use fileManagerLoaded event instead of fileManagerLoading event:
<head>
<script type="text/javascript">
function fileManagerLoading(sender, e) {
//Adding a context menu item
Ext.override(fileManager, {
createViewItemContextMenu: function () {
var me = this;
var menu = this.callParent();
menu.add([// or menu.insert(0, [
{
text: "Test menu item",
handler: function () {
alert(
"Clicked test menu item!\n"
+ "Context menu record:"
+ me.contextMenuRecord.data.name
);
}
}
]);
return menu;
}
});
//Adding a column for "Details" view layout
Ext.override(fileManager, {
getViewColumnsConfig: function () {
var columns = this.callParent(arguments);
columns.push({
text: "Test column",
dataIndex: "name",
tdCls: "x-item-value",
renderer: function (value, meta, record) {
//you can use the name value as an id to
//get your own corresponding value here
//e.g if you have an object customValues
//with file names as key, you can retrieve
//and return customValues[record.data.name]
return record.data.name;
}
});
return columns;
}
});
}
function fileManagerLoaded(sender, e) {
var fileManager = sender;
//Adding a new ribbon tab
fileManager.ribbon.addTab({
title: "Test tab",
items: [
{
title: "Test group",
items:[
{
text: "Test button",
iconCls: "", //css class for image
icon: "", //or url to the image
scale: "small", //or medium or large
handler: function () {
var selectedItemNames = Ext.Array.map(
fileManager.currentViewSelection,
function (item) { return item.data.name; }
);
alert(
"Clicked test button!\n"
+ "Current selection:" + selectedItemNames
);
}
}
]
}
]
});
}
</script>
