This is the case: I have a Mesh and PointLight added to the pane and I want to take snapshot from pane and show the result in the image view. But it only works when I add the pane to the scene. Is there any way to take snapshot from a node which has been not added to the scene? Accoring to documentation of Node.snapshot NOTE: In order for CSS and layout to function correctly, the node must be part of a Scene (the Scene may be attached to a Stage, but need not be). You can create new Scene without attaching it to Stage and even without displaying it: WritableImage writableImage = new

Is there a way to set two root nodes for one TreeView? I found many example if simple TreeView but there is no useful example for my case. No: a tree only has one root node. To get the effect you want, create a dummy root node and add your two nodes to it. Create the TreeView with the dummy root node and call tree.setShowRoot(false) , so the dummy node does not appear. final TreeItem<String> root1 = new TreeItem<>("root 1"); final TreeItem<String> root2 = new TreeItem<>("root 2"); final TreeView<String> tree = createTreeView(root1, root2); // ... private TreeView<String> createTreeView

ControlsFX class Dialogs is marked as deprecated. What to use instead? Boomah This blog post explains it all: http://fxexperience.com/2014/09/announcing-controlsfx-8-20-7/ This release has been brewing since 8.0.6 was released on May 29th – so basically four months. This is not typical for us (we normally have much quicker releases), but Eugene and I were both distracted on a major undertaking – elevating the ControlsFX dialogs API and implementation into the next release of JavaFX itself (it’ll be appearing in JavaFX 8u40, although the API is vastly different than what you see in ControlsFX 8

This is a follow up question based on TreeView in a table cell Java FX 8 I am having a table in which a particular column has to popup a treeview on click. I am defining the table column's cellfactory as follows col4.setCellFactory(new Callback<TableColumn<User,DepartmentTree>, TableCell<User,DepartmentTree>>() { @Override public TableCell<User, DepartmentTree> call( TableColumn<User,DepartmentTree> param) { TableCell<User, DepartmentTree> deptCombo = new TableCell<User,DepartmentTree>() { @Override public void startEdit() { setGraphic(testtree); } @Override public void cancelEdit() {

I have this example of Pie chart data: import javafx.application.Application; import javafx.collections.FXCollections; import javafx.collections.ObservableList; import javafx.concurrent.Task; import javafx.event.ActionEvent; import javafx.event.EventHandler; import javafx.scene.Group; import javafx.scene.Node; import javafx.scene.Scene; import javafx.scene.chart.PieChart; import javafx.scene.chart.PieChart.Data; import javafx.scene.control.ContextMenu; import javafx.scene.control.Label; import javafx.scene.control.MenuItem; import javafx.scene.effect.Glow; import javafx.scene.input.MouseButton

I have created an image on a Canvas which is scaled down for display using a transformation. It is also in a ScrollPane which means only a part of the image is visible. I need to take a snapshot of the entire canvas and save this as a high-resolution image. When I use Canvas.snapshot I get a Writable image of the visible part of the image after scaling down. This results in a low-res partial image being saved. So how do I go about creating a snapshot which includes the entire canvas (not only the viewport of the scrollpane) and with the resolution before the transformation downwards? I am not
