Answered 2021-Oct-05 at 15:05I'm just relaying what I found in an closed issue but sjimbonator says
if you set constrained to true on your InteractiveViewer and wrap its child with an OverflowBox with Alignment.center it will center the tree.

QUESTION
I am getting a duplicate class error for AWS API and AWS Appsync services in my android app. I have tried downgrading the versions but that causes bugs in other files. I have tried the solutions in this post: Android Studio: Resolving Duplicate Classes. None of these seem to work as they only cause more bugs or no changes.
Here is the error:

Answered 2021-Sep-08 at 16:19if you want to invoke AWS Services from an Android app, then I suggest looking at the new AWS SDK for Kotlin. This is still a new API; however, there is an example that shows you how to invoke AWS Services such as Amazon DynamoDB.
As far as duplicate libs, I saw that too when i specified the sns dependencies. To eliminate that issue, the Gradle build file was set to:

QUESTION
I recently started adding graphic charts to a MacOS application I wrote. The first chart is great and I added a second chart where I ran into a fundamental way the code operates that I did not/do not understand. The only reason I ran into this is because in my second chart I used random to draw some bubbles inside confined areas. It works nicely but when I resized the view window a little bit the chart redrew everything and since I was using random the first set of bubbles remained in the screen and the second set were added to the screen. So I made a simple example to illustrate.
...ANSWER
Answered 2021-May-07 at 07:31Why does custom NSView redraw when window is resized or moved (drag) to an secondary display (monitor)?
A window resize causes view resizes. The secondary display may have a different resolution.
How do I stop this from happening.
You can't, draw is called multiple times.
I want to draw the chart and that is it.
Create a NSImage of the chart and display it in a NSimageView.
the first set of bubbles remained in the screen and the second set were added to the screen
Calculate the coordinates or rect of the circle once when the view is created so draw will always draw the same circle.
QUESTION
as the title suggest, i am trying to understand the purpose of org.apache.jena.sparql.core.GraphView in the Jena Architecture. I'm currently studying the SPI.
the doc says:
Implement a Graph as a view of the DatasetGraph. It maps graph operations to quad operations. GraphUnionRead provides a union graph that does not assume quads, but loops on graphs.
https://jena.apache.org/documentation/javadoc/arq/org/apache/jena/sparql/core/GraphView.html
I wonder more in which context this is used, as in at a high level, what is the intrinsic purpose of the class ?
Regards,
Maat
...ANSWER
Answered 2021-Apr-30 at 17:34It is a "view" in the database sense.
DatasetGraph is a collection of graphs, a default graph and zero or more named graphs. It has operations to give access to the default getDefaultGraph and any named graph getGraph. These graphs can then be used with the Model API.
Some (in fact, most) DatasetGraph store data as a set of triples and a set of quads. GraphView presents the GraphAPI leaving the storage in-place. Changes through a GraphView do update the underlying DatasetGraph, directing a triple add/delete to the right part of the DatasetGraph, and for named graph view, converting to a quad add/delete.
Transactions on a GraphView are transactions on the DatasetGraph.

I am currently making an Android app using android Studio, and one of the features it has is it collects how many times the user has clicked a certain button and stores it, and displays it on a bar graph. It's a mood tracker. However the counter is on a fragment and whenever I leave the app or the activity it just resets the value which is not what I want.
The code for the bar graph:

Answered 2021-Feb-15 at 08:00Move your SharedPreferences from onPause to onCreate (if it's Activity) or to onActivityCreated (if it's Fragment). I recommend write a function and call that in your onClickListener, then each time user clicks on the button, it will store at your SharedPreferences.

Install GraphView
You can use GraphView like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the GraphView component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
