Getting selected text from the script history

Here’s how to get the selection from the script history. This is how the Repeat command works.

def GetScriptHistoryView():
	oLayout = Application.Desktop.ActiveLayout

	# See if the script history is a view of it's own
	oViews = oLayout.Views.Filter( "Script History" )
	if oViews.Count == 0:
		oViews = oLayout.Views.Filter( "Script Editor" )

	return oViews(0)

oLog = GetScriptHistoryView()
text = oLog.GetAttributeValue( "historyline" ) if oLog else "<Nothing>"
print text

Getting the ICE tree view from a menu callback

How do you get the ICE Tree view in a menu callback? For example, if you add a menu item to the ICE Tree > User Tools, how does the menu item callback get the ICE Tree view?

The answer is actually in code I posted before, but that was in a blog post titled Getting the selected ICE nodes. So, with that title, you wouldn’t necessarily think to look there.

So what’s the answer? Uses Context.GetAttribute( “Target” ). For custom menus in the views like the ICE Tree view, the Fcurve Editor, and the Material Manager, the Target attribute is the View object. And once you have the View object, you can get the View attributes.

#
# Callback added to the menu item with Menu.AddCallbackItem
#
def My_menuItem_Callback( in_ctxt ):

	# Get the ICE Tree view
	oView = in_ctxt.GetAttribute("Target")
	
	# 
	LogMessage( 'View: ' + oView.Name )
	
	# get the selected nodes
	nodes = oView.GetAttributeValue('selection')
	LogMessage( 'Selected nodes: ' + nodes )

Soapbox alert…
This post illustrates why indexes are a good thing…with them, you can find information no matter what page or heading contains the information.
For ICE trees, you’d have index entries something like this:

  • ICE tree
    • view attributes
      • target
      • container
    • selected nodes, getting
    • view, getting
    • ICETree node, getting

Getting the selected nodes in an ICE Tree

You can get the selected ICE nodes through the selection view attribute.

First, you have to get the ICE Tree view. You could try to get the view by name:

var oLayout = Application.Desktop.ActiveLayout;
var oICETreeView = oLayout.Views( "ICE Tree" );

but if the ICE Tree view is part of a layout (like the ICE layout) that won’t work, because the view has a different name (for example, in the ICE layout, the view name is “lower_panel”). To be sure you get the ICE Tree view, whether it is floating or embedded, filter by the Views by type.

// Get the ICE Tree views
var oLayout = Application.Desktop.ActiveLayout;
var oICETreeViews = oLayout.Views.Filter( "ICE Tree" );

// Now get the selected nodes 
// and log the names of the selected nodes
var x = oICETreeViews(0);
var a = x.GetAttributeValue( "selection" ).split(",");
LogMessage( a.length );

for ( var i in a )
{
	var oNode = Dictionary.GetObject( a[i] );
//	LogMessage( classname(oNode) );
	LogMessage( oNode.Name );
}
