For rendering purposes I need a vtkImageData object with two components where each component consists of the single component of two vtkImageData objects. How can I achieve that? Is there a vtkImageAlgorithm for this like http://www.vtk.org/Wiki/VTK/Examples/Cxx/ImageData/vtkImageWeightedSum?
Thanks,
Dirk
I would use vtkImageAppend or vtkImageAppendComponents:

In 3d Model of Autodesk Forge, We want to change the colour of the model with passing the DBId without selection. How can we do it? please help on this.. we are unable to find any reference on this.
If you already have a dbID of an object you'd like to color, you can use the viewer's setThemingColor method.
If you're asking about how to get dbIDs of objects without selecting them, there are different ways. For example, you can iterate through the scene hierarchy (as explained in this blog post), or obtain dbIDs of objects with specific properties (using the getProperties method).
I'm new to nightwatch.js. I work in QA and the developers don't want to use ids or classes for the automated tests. They want to use data-test. So for example data-test="nav-button".
Is there way to find elements and click elements using this attribute in nightwatch.js?
This is actually pretty simple. Just put the data-test in square brackets after the element type. See below for examples. In these examples, the data-test attribute is in an anchor tag.
.waitForElementVisible('a[data-test=nav-button]')
.click(a[data-test=nav-button])
I have multiple views in multiple nsf databases that I want to perform a view.update on, build an array of records, and show the results in one ListView. What would be the best way to do this in regards to performance? One idea that came to mind was to:
Perform .update() method on views
In callback of each update, push records to a (global?) array
Set array to ListView
Am I thinking about this correctly? Is there an example of doing this in Domino To Go?
Thanks for any tips.
I would chain the .update() methods on the views and in the callback of the final update I would sue a DTGDatabase object with getAllEntriesByKey() method to get the records, it's faster than using NotesView.getAllEntriesByKey of each view.
Or use DTGDatabase.getAllEntriesBySQL with a proper SQL statement, that way you can do a JOIN and it's the fastest option.
I have core data app with an entity OBSERVATION that has as one of its attributes DEALNAME.
I want to reference through Interface Builder or by making custom modifications to an NSArrayController a list of unique sorted dealnames so that I can use them in a pop-up.
I have attempted to use #distinctUnionOfSets (and #distinctUnionOfArrays) but am unable to locate the proper key sequence.
I can sort the ArrayController by providing a sort descriptor, but do not know how to eliminate duplicates.
Are the #distinct... keys the right methodology? It would seem to provide the easiest way to optimize the use of IB.
Is there a predicate form for removing duplicates?
Or do I need to use my custom controller to extract an NSSet of the specific dealnames, put them back in an array and sort it and reference the custom array from IB?
Any help would be appreciated. I am astounded that other have not tried to create a sorted-unique pop-up in tableviews.
You need to take a look at -[NSFetchRequest returnsDistinctResults]. That is the level you need to be handling the uniquing of data.
Although I do not have a definitive answer for you, I think there are two ways you can go about it.
The way you already started. You need to bind the contents array of the PopUp button, not just against the arrayController.arrangedObjects, but continue on the path and somehow filter only objects with distinct "DealName"s. This means - the arrayController presents ALL the entities (and may sort them for you) but the PopUp button will have its contents filter via some sophisticated binding to the array controller.
Make your filtering at the ArrayController level (as suggested in another answer here). Here it depends how you set up the array controller. If It is set up to use an "Entity" (vs. "Class") which means the array controller will fetch CoreData entities directly - you can modify its "Fetch" to only bring a subset of the "OBSERVATION" entities with distinct values of "DEALNAME". I don't know how to control WHICH entities are filtered out in this case. Otherwise, you can setup the arrayController to work with "Class" objects, and then you can fetch the entities yourself (in code) and populate the arrayController programmatically, with just the entities you like.
In the second option, the Popup button should be bound normally to the arrayController's arrangedObjects.
I've got a SubSonic DAL - works great.
Two classes: TblReceipt and TblReceiptLineItems.
I can create a parallel class of TblReceipt, but seems like a waste, so here's what I need to do:
Have a Class TblReceipt with one additional member, "ReceiptLineItems" - which is simply an ArrayList. This array list will be populated with TblReceiptLineItems types.
So for each Receipt, there are 1..* ReceiptLineItems stored in the array, then the whole thing is serialized.
How can I accomplish this with my existing SubSonic DAL?
A quick code sample would be useful too.
Thank you.
Use a partial class. All classes in Subsonic are defined as partial. What you do is (in a separate file than the one that is generated by Subsonic), you create another part of the partial class with the additional property.
