问题 I need to save some part of canvas to image that is from x1 > 0 and y1 > 0 to some x2 > x1 and y2 > y1 .

SSCCE: import javafx.scene.control.Label; import javafx.scene.layout.HBox; import javafx.application.Application; import javafx.scene

问题 I'm using Directory Chooser for set a TextField with the selected path. If I choose some directory like Desktop, or any other folder it returns the path, BUT if I choose the directorys from my library like my Documents (C:\Users\Victor\Documents) it returns null. Is it a bug?? I'm using the code below: DirectoryChooser chooser = new DirectoryChooser(); chooser.setTitle("Selecione o diretório"); File defaultDirectory = new File(folderChooser); chooser.setInitialDirectory(defaultDirectory);

问题 So I have a Pane with some components in it (Groups and Polygons) and I wanted to make a copy of this Pane, but whenever I do the following it seems like it deletes the children of the original Pane and transfers it to the new one. Pane pane1 = new Pane(); pane1.getChildren().addAll(poly1, poly2, poly3, group1, group2); Pane pane2 = new Pane(); pane2.getChildren().addAll(pane1.getChildren()); So my question is, how do you copy these children without removing them from the original Pane? 来源：
