问题 I would like to change the color palette. The colors are by default have a transparency of 30%. Is it possible to replace the color palette? 回答1: Based on this solution, you can replace the color palette once you get the rectangles and their colors. For instance, you can make brighter all the palette: @Override public void start(Stage primaryStage) { ColorPicker picker = new ColorPicker(); StackPane root = new StackPane(picker); Scene scene = new Scene(root, 500, 400); primaryStage.setScene

问题 With Textflow.setMaxWidth(double) I can achieve text wrapping. But how can I adjust the width of TextFlow afterwards so that it is based on the actual wrapping position? In other words, how to let the TextFlow bounds snap to all of its children Text bounds to get rid of the empty space on the right: **Edit** I have made some progress on this issue. My class derived from TextFlow now contains: double maxChildWidth = 0; for (Node child : getManagedChildren()) { double childWidth = child

问题 My context: 9-ea-113 (that is javafx now fully modularized, without jfrt.jar) eclipse-neon-M6 with the current beta support for java9 (running on java8, if that matters) win7 Something simple like import javafx.application.Application; public class FirstApplication extends Application { // } doesn't compile because the javafx.xx packages are not found.

问题 I'm looking for form validator similar to these examples: or Is this custom JavaFX component or this can be done using standard JavaFX? Is there any example how I can create form validator similar to these? 回答1: Just to give you a kick start, here is a small example with using ContextMenu. May be ContextMenu is not an ideal Control for this scenario and you are free to replace it with Label, Text etc. Keep the TextField and Label inside a HBox (with Label being hidden initially) and the HBox

问题 How to align title of only one column in tableview? The following css aligns all column-header but I want to align just one column: .table-view .column-header .label{ -fx-alignment:CENTER } 回答1: You can do that now with recent versions of JavaFX. Java 1.7 This worked for me with Java: 1.7.0_45 / JavaFX: 2.2.45-b18). It should be a recent version because it requires RT-14909 The column-header will automatically get the same "Id" as the TableColumn! Therefore your TableColumn(s) need an (CSS-)

问题 Say I have a JavaFX app with an observable class SomeObservableClass with some Properties: public class SomeObservableClass{ private StringProperty prop1 = new SimpleStringProperty(); private DoubleProperty prop2 = new SimpleDoubleProperty(); ... constructors, getters and setters } and another class which has a property: public class ParentClass{ private ObservableList<SomeObservableClass> sOC = FXCollections.observableArrayList();` } In this parent class I add a listener for the observable

问题 I noticed a really strange behaviour with menu accelerators on the JavaFX (system) menu. Some key combinations don't work at all and others are interpreted as the wrong key. For instance, when you use the CMD+CLEAR key as accelerator, it gets changed as the CMD+Page Down down key (both in the menu text and in the actual response to a keyboard event). The '-' (MINUS) key doesn't work well at all and while, CMD + - shows up well in the menu, it never gets triggered when you press the keys. When
