javafx-8

问题 In Java Swing it is possible to put a menu on the right side of the menu bar using: menubar.add(menu1); menubar.add(Box.createHorizontalGlue()); menubar.add(menu2); This will put menu1 on the left and menu2 on the right. This function is (obviously) not available in JavaFX . In JavaFX , I have seen that the same can be achieved for a toolbar using: final Pane rightSpacer = new Pane(); HBox.setHgrow( rightSpacer, Priority.SOMETIMES ); Although, this workaround is not usuable for menus.

问题 Is there any event handler present in Java FX, if i close a window directly bt pressing [X] button on Top right side. Which events gets fire in this case ? Nothing is working so far , neither setOnHiding not setOnCloseRequest() Please help. 回答1: Try this one import javafx.application.Application; import javafx.event.EventHandler; import javafx.scene.Scene; import javafx.scene.layout.VBox; import javafx.scene.text.Font; import javafx.scene.text.Text; import javafx.stage.Stage; import javafx

问题 We are trying to count the number of rows in a TextArea Here are the TextArea properties PrefWidth 600 and PrefHeight 620 with MaxHeight 620 Wrap Text is set to true. We are using JavaFX 8 with Scene Builder We have a textPropertyListiner that will fire an Alert when the TextArea.getLength is greater than some value The issue with this method is it does not consider the user entering a carriage return \n So we implemented this code to capture the \n String toCount = txaDiaryEntry.getText();
