问题 I would like to hide the input caret of a TextField in JavaFX8. I already tried to set the text fill to white (my TextField has a white background), but then my user input also disappears. The problem is that the textfield still needs focus, so I also thought of some EventHandler which listens to user input, and focusses on the textfield when a key is pressed, but then I would miss the first key typed. Anyone that knows how to do this? Or is it not possible in JavaFX8? 回答1: Update for Java

问题 In JavaFX, if I have a scene with 2 VBox elements and each VBox has multiple Label in it. If I set the top VBox to invisible , why does the bottom VBox not move up the scene where the top VBox was ? The VBox is invisible but I would expect the other objects to move into its place. I am using FXML to load my controls. 回答1: Node.setVisible(boolean) just toggles the visibility state of a Node . To exclude a Node from its parents layout calculations you additionally have to set its managed state,

问题 I am trying out JFX Drag and Drop feature in my application (later connecting the objects in a sequence). I could not find any easy way to drag and drop my ImageView/Button at suitable position in my pane, hence I am planning to apply use of GridPane. The GridPane would be a large canvas with more than (50x50) cells. If I specify in my code that I need to drag and drop by ImageView at, let's say, (2,2) cell, I am able to do it. But, I need to give that access to my user. User could move the
