问题 I'm looking a way to draw shapes in a Region (JavaFX8) I've seen some examples that set the region style like this: -fx-shape : "M 3.0313 0 L 0 74 L 7.9688 74 L 4.9375 0 L 3.0313 0 Z"; Can anyone give an explanation of the meaning of this string?

问题 I know that you can add Anchor Pane contains in fxml like:'AnchorPane.bottomAnchor="0.0"' but can you set AnchorPane constrains in java code? 回答1: There are a set of static methods on AnchorPane which you call with the node and the constraint.

问题 So I'm trying to load and save Images into an imageView where the location of the image is chosen through a file browser. I've been working on this for several days now and I'm gonna have a stroke if I can't get it fixed. I've tried everything I can think of. Thank you in advance for helping.

问题 Can a default Javafx table sort on multiple fields by dragging the columns on a dropzone? My user need to select one or multiple columns to sort on different columns.

问题 I am trying to set some javascript items on my page, but the items are getting set after the javascript runs on the page. So for example, I created a Console.log() method to display stuff in my java console for debugging purposes. But the items are getting set after the page code runs so the logging doesn't work (See second block of code). Is there a way for me to initiate the code before the javascript on the page runs? So, here is how I am initiating the item in my Java application:

问题 I'm trying to display travel connections in a TableView. So far that works like a charm. Now I'm kinda stuck trying to get details of a connection to be displayed in between table rows. This should happen on selecting a table item. The problem is, that the details are in a different format than the connections I'm displaying. So I would need to put a panel between two table rows. Is this at all possible? 回答1: The "proper" way to do this would be to create a custom skin for TableRow and use a

Problem is: I have no idea how to reference this ThisCellofThisRow . 回答1: Not sure exactly what you want to do, but you could change the pseudoclass

问题 I want to extend a Class from Pane and then use the setContent() method from a tab from TabPane to display the Pane inside this Tab. It worked in Swing when I extended from JPanel but if I try something similar in JavaFX it only displays the tab itself and stays empty below. I want to handle the content of the tabs in separate classes, am I doing something completely wrong here?
