I would like to drag button from one VBox to another.. is it possible to do that with JavaFx 2.2?
I found what I was looking for.
To get source object I'm using event.getGestureSource() method...
All I need to do is add this object to target
target.getChildren().add(event.getGestureSource());

I have successfully populated a TreeView via creating a TreeDataProvider and customized the icons and its collapse-able property. Now I want to be able to drag and drop its ViewItem(s) onto a WebView. There are unfortunately no samples for drag and drop. Reading through the TreeView source, ViewItem(s) are created in HeightMap.OnInsertItems() via the TreeView.createViewItem(), from the derived class.
The public TreeView.onInsertItem() would appear to be a great extension point, extending TreeView and onInsertItem() and capturing its ViewItem parameter. This Unfortunately, the creation of the concrete class, ExtHostTreeView, that is ultimately created, is buried in layers of private methods (createExtHostTreeViewer()).
Strangely, the ViewItem has a setter for draggable. However, how would you ever get a reference to the ViewItem to set it? If there is a way to do this please point me at an example. If there is not, I would be glad to fork and implement it. Leaving the existing onInsertItem and perhaps add an array of handlers to be added to with an addOnInsertItemListener() method? Or perhaps use RxJS?
There are so many places this could be used. You could drag template fragments into documents or code, DSL rules into a expert system, configuration file values into parameters or right hand values (generating the code to retrieve the value). Thank you for any assistance.
It seems that drag and drop in custom views is currently not supported. There's a (fairly popular) feature request for it here:
Add drag and drop for contributed tree views (#32592)
As of version 1.66 (March 2022) there is a TreeDragAndDropController which can be used for some drag & drop actions.
In April 2022, their sample focuses on drag & drop within a tree view: https://github.com/microsoft/vscode-extension-samples/blob/main/tree-view-sample/src/testViewDragAndDrop.ts
It is also possible to use the text/url-list type as described in the documentation to allow for dragging files to the editor panel: https://github.com/microsoft/vscode/blob/dc2f5d8dd1790ac4fc6054e11b44e36884caa4be/src/vscode-dts/vscode.d.ts#L9843-L9859
It is not clear to me yet whether it is possible to drag arbitrary data to webviews or to use standard HTML5 drag & drop API in a webview to allow dragging data to a custom tree view.
I am trying to build an interface of my RTS, I want to create basic HUD with some buttons and time/date grid.
I have created widget blueprint and designed as I needed.
This is how I am trying to create HUD, get its reference and put it into variable for next use.
This is how I am trying to add it to the viewport on the beginPlay.
Everything is happening inside PlayerController. No widget is shown on the display.
I tested and it works well using your way, UE4 version is 4.21.
Let me know if that doesn't work for you.

I have added a container named btnBar with boxlayout(x-axis) on a form. the container has 4 buttons of custom class MyButton that extends from Button itself. When i add actionlistener to one of the buttons in the container it gets invoked for each n every button. Even the actionevent.getsource.gettext method returns the same value irrespective of the focus. I have added the buttons through an array and m trying to use is something like this:
btns[0].addActionListener(......)
Where am I going wrong?
got is solved buddies...actually was using setfocus() to traverse within the btnBar on buttons...but needed to use setFocused() method of form too....after setFocus()....dnt hammer ur brains now....
You must never use setFocus, you should use setFocusable to toggle focusability and requestFocus to get the focus to a specific component.
You should also migrate to Codename One, since LWUIT is pretty much unmaintained.
