anyway - that part makes sense

so as for picking the node Rectangle - this is the part of the code that determines where you have dragged your node to and where it should go on the rectangle

From the discussion from yesterday, you said I might be able to use the dragboard without clipboard. If that's true, can I still use this snippet of code without worrying about determining a pickRectangle?

I want to totally understand what I might be able to do - would it be possible to pick up my graphical object with Mouse Event handling and use setOnDragDropped or would I need to use these dragboard methods to utilize all mouse events

I could just convert everything to mouse handling of course, but I wasn't sure if there was a good reason to keep dragboard

I think your clipboard operations make sense if you're getting Tiles or Tile properties from outside the app. For example, say you drag a .json file onto your app and it loads a layout of Tiles. Or, say you paste a CSS color onto a Tile from the clipboard. Otherwise, clipboard operations may interfere with how users expect to work with the system. I can't think of an app that would wipe out the clipboard just by dragging. For instance, if you copy a URL into the clipboard, drag a text object in Adobe Illustrator onto the canvas, then paste, you'd expect the URL to appear. It won't if the clipboard is filled in with the Adobe Illustrator serialized text object.

Maybe you can expand your testing a little to see if this is how it works? Go to a text editor, copy something. Then, use your app. Go back to the text editor and see what's in the clipboard.

Also, clipboard would be useful to paste a Tile outside of the app. This is probably getting beyond your requirements, but you could export the Tile as a rectangle for display as a vector graphics object in Adobe Illustrator.

I understand that part

OH - I'm so sorry, I did not realize that dragboard was a subclass of clipboard

okay, so I guess I'll half to rewrite it all to be mouse events

it can be a little confusing. for example, there is a MouseDragged event that doesn't involve a DragEvent.

i believe these mouse events will also work with touch

okay! give me a little time, I'll come back with some code

oh, is the offset variable to deal with the size of the square?

could I still use the grad.add method?

offset is to help with the tracking. if you select close to the edge of the circle versus the center

if there's no offset, then during my move operation, the object would immediately jerk to the center of my mouse cursor

actual tornadofx question this time: can you call functions without parameters the same way you can in certain instances with java?

@amanda.hinchman-dominguez uploaded a file: Untitled

I'm not sure if I can call this::dragTile or likewise because it still requires a parameter

if that's the case, should I maybe try graphic.addEventFilter(MouseEvent.MOUSE_MOVED, highlightTile(event))? unfortunately, there is no defined event to be recognized

check the section on function references http://kotlinlang.org/docs/reference/reflection.html#function-references

@carlw how is startMovingPiece being called?

I decided to attach a similar method to the event onMousePressed

btw, TornadoFX has an equivalent of addEventFilter and that's object.setOnMouse[Action] { e-> something }

val gridRow = (mpLocal.x/gridInfo.columns) as Int <-- cast can never succeed?

in my build.gradle I have a dependency to the gradle tooling api :

implementation “org.gradle:gradle-tooling-api:4.3.1”

but when I start the app, I get an error:

org.gradle.tooling.GradleConnectionException: Could not create an instance of Tooling API implementation using the specified Gradle distribution ’<https://services.gradle.org/distributions/gradle-4.1-all.zip>'.
