问题 I've been using custom fitting chart from Ensemble Test, which works great. Problem is I cannot use it in FXML. Someone else seemed to do that successfully. Error: Instances of curvefittedareachartappfxml.CurvedFittedAreaChart cannot be created by FXML Loader. FXMLDocument.fxml <?import javafx.scene.chart.*?> <?import java.lang.*?> <?import java.util.*?> <?import javafx.scene.*?> <?import javafx.scene.control.*?> <?import javafx.scene.layout.*?> <?import curvefittedareachartappfxml

问题 I need to apply multiple effects ( mainly innershadow and dropshadow ) through CSS. But I'm not able to chain these effects. Is there CSS equivalent for setInput() of javafx.scene.effect.Effect? So far I found only this link. It indicates something about fixes but no details about how to use chaining. EDIT : Further explanation if question is not clear: to apply effect through css, -fx-effect is used. I need to apply multiple effects to same node. How to "chain" these effects in CSS? This can

问题 I would like to know if there is a way to determine if the mouse collides with a node's children, in less words, In the example below, If I click on the Group the output is: "Group!" If I click on the image the output is: "Group! Image!" Is there a way to put code in the "group.setOnMousePressed" in order to check if the mouse in on the image and in that case don't do anything and just execute what is in the "group.setOnMousePressed", in order to have this output clicking on image: "Image!"

问题 The problem I'm having is that the FlowPane is leaving a lot of excess space, it could possibly be the Popup, although I think the popup size is the content size. For the sake of debugging I've wrapped the text in a BorderPane to show the bounds of the text. The component I'm focusing on is the error popup. CSS .warning-popup { -fx-padding: 10px; -fx-hgap: 10px; -fx-vgap: 10px; -fx-background-color: #704745; -fx-border-color: #C8C8C8; -fx-background-radius: 2px; -fx-border-radius: 2px; }

问题 Is it possible to switch between tabs in tab pane with delay in JavaFX? For example I want to when I change selection tab to tab2 I see a transition on the tab that is selected and then tab2 will be shown . 回答1: I think you can use the existing TabPane , but you'll need to manage the tab content yourself; just switch the tab content for the selected tab with a change listener. import java.util.HashMap; import java.util.Map; import javafx.animation.ScaleTransition; import javafx.animation

问题 I'm making a JavaFx app. Today I integrated a login panel and a registration panel to it. After integrating those, I started getting a fatal error whenever I ran the app which didn't happen earlier.

问题 First, I'm familiar with Java and Swing but am new to FX, and working in FX8. I'm trying to put a JavaFX LineChart as a cell in a TreeTableView. I've gathered that I need to use setCellFactory on the column that will show the graph, and I'm defining a custom version of TreeTableCell as follows public class SparklineCell<T> extends TreeTableCell<T,Series> { private LineChart getEmptyLineChart() { final NumberAxis xAxis = new NumberAxis(); final NumberAxis yAxis = new NumberAxis(); final

问题 I'm working with a TreeTableView ( JavaFX 8 ). There are some tree nodes, which have to be disabled for selection. I had tried the selection event, but it doesn't work. Please find the below code for more information. treeTableView.getSelectionModel().selectedItemProperty().addListener( (observable, oldValue, newValue) -> { // utility node if(newValue.getValue() instanceof UtilityRoot ) { return; } } ); How can I prevent some TreeItems from any mouse and keyboard selection? 回答1: What you try
