问题 I'm a newcomer when it comes to JavaFX and I recently encountered a problem which really confuses me alot. I'm using a class called "MainController" which controlls an FXML-File containing a TabPane. Each tab is controlled by another controller. But there is one situation in which a tab needs to be deleted, so I need access to the MainController instance to remove the currently active tab from the pane. Whenever I'm using this code to get an instance of the currently running MainController, I

问题 I have extended TreeCell and TreeItem class. MyTreeItem contains a custom property which I use inside MyTreeCell to render graphics/font etc. The problem is when I set MyTreeCell.customProperty I'm not sure how to make the TreeView/Cell redraw. For example: public class MyTreeItem extends TreeItem { Object customProperty public void setCustomProperty(Object customProperty) { this.customProperty = customProperty // how to fire a change event on the TreeView? } } Any comments on the solution or

问题 I want to repeat one node in scene . Is it possible ? for example I have an anchorpane and 3 panes on it . I have one button on pane(1) and I want to add it to pane(2) after some process in program ... .

问题 This question goes further where JavaFX: Disable multiple rows in TableView based on other TableView stops. I want to generate a more general topic, of which other people could also benefit. I also have the two tableviews. I also want to disable a row in table2 when table1 contains the same object. This is achieved with the code below: //Check if a row needs to be disabled: this is achieved with a rowfactory ObservableList<String> listOfSKUs = EasyBind.map(table1.getItems(),Product::getSKU);

问题 A relative Java newbie question. I'm trying set a TableRow 's background colour based on whether or not it's selected and/or whether or not a boolean value in the data model is true. I've found ways of doing each but not both together in the same setRowFactory . What I would like to end up with is this (albeit with horrible colours for example purposes only!): How would I go about achieving that? This is what I found wrt changing row colour based on selection. It's adapted from user James_D's

问题 I have some kind of drawpane, where the user can draw different kinds of Shapes, like Pathes, Rectangles, Texts, etc. Now I´d like to persist the DrawState, so that I can recreate it at any time. I just tried it with xstream, but like usual I get a whole lot of dependencies within these Shapes when persisting it in XML. After some research I found this Thread here: Serialize JavaFX components I liked the idea of jewelsea using the SceneBuilder API to serialize my shapes, since they are all
