javafx

问题 I am creating javafx projects in STS(4.6.1) with e(fx)clipse plugin and scenebuilder. Everytime I create a new project, I have to add the VM arguments in run configurations: --module-path "/home/path/to/javafx sdk/lib" --add-modules javafx.controls,javafx.fxml otherwise the program ends with the error message which says Error: Could not find or load main class application.Main Caused by: java.lang.NoClassDefFoundError: javafx/application/Application I have to do this for every javafx project

问题 button.setOnAction(new EventHandler<ActionEvent>() { @Override public void handle(ActionEvent e) { label.setText("Accepted"); } }); In the code above we are defining what will happen when we press the button. This is all good but I wanna create new ActionListener and then add it to my button. Normally in JButton I can just add ActionListener like this: button.addActionListener(someControllerClass.createButtonListener()); In code above createButtonListener() returns ActionListener. My question

问题 I'm looking for a solution for the following problem: I've built up a javafx GUI with SceneBuilder and added tooltips to some of the labels I added. However, the tooltips automatically hide after ~5 seconds. Sometimes this is not enough for the user to read the tooltips whole content. I would like to show the tooltip as long as the cursor stays above the label and completely disable this autoHide function. I did not find a way to customize the time a popup is shown or how to disable the auto

Sample CSS: .root{ -fx-background: #325c81; -fx-default-button: #77a3ca; -fx-base: #a7c4dd; } The application has 3 ColorPicker controls that need to allow users to select a color for each of those properties and save back to the CSS file. I have no problem with actually writing the CSS file, but I cannot find a

问题 The question seems simple, but there is a specific way I have to implement my code that is causing confusion. So in step #3 I need to register the source object with the event handler. The ButtonHandler class is already set up for me but I can't figure how to connect these to register the button. The resources I was given appears to use different logic to connect javaFx events and I can not make a connection between the logic this code should use with the logic I was given. I can elaborate

问题 I'm making a sorting algorithm visualizer and i want the UI to update in real time to show how it works, step by step. But the UI only updates when the sort() method is done, I want it to update when updateHeight() is done the sort() method is initiated by an onAction @FXML public void sort() throws InterruptedException { minHeight = RectHeight[0]; counter = 0; minIndex = 0; temp = 0; for(int i=1;i<RectList.size();i++){ System.out.println(RectList.size()); System.out.println(counter); sort2()
