我想知道在使用TextField或TextArea时如何使插入符号可见和/或闪烁。我在GUI中创建的那些工作,因为字母在键入时出现,但没有可见的插入符号。
我查看了TextField文档但没有关于是否可见。我希望找到“setCaretVisible(Boolean);”
这一行我是否必须通过CSS显示它?如果是这样,任何建议都会受到欢迎!
请参阅我快速整理的代码来说明问题:
import javafx.application.Application;
import static javafx.application.Application.launch;
import javafx.event.ActionEvent;
import javafx.geometry.Insets;
import javafx.geometry.Pos;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.Tab;
import javafx.scene.control.TabPane;
import javafx.scene.control.TextArea;
import javafx.scene.control.TextField;
import javafx.scene.input.KeyCombination;
import javafx.scene.layout.BorderPane;
import javafx.scene.layout.HBox;
import javafx.scene.layout.VBox;
import javafx.scene.text.Text;
import javafx.stage.Stage;
import javafx.stage.StageStyle;
public class Test extends Application {
public static void main(String[] arguments) { launch(arguments); }
@Override public void start(Stage stage) {
Scene scene = new Scene(new Group());
scene.setRoot(new BuildLayout(stage));
stage.setTitle("Application Name");
stage.setScene(scene);
stage.initStyle(StageStyle.UNDECORATED);
stage.initStyle(StageStyle.TRANSPARENT);
stage.setFullScreen(true);
stage.setFullScreenExitHint("");
stage.setFullScreenExitKeyCombination(KeyCombination.NO_MATCH);
stage.show();
}
}
final class BuildLayout extends BorderPane {
protected BuildLayout(Stage stage) {
TabPane tabpane = new TabPane();
Tab tab = new Tab();
tab.setGraphic(new Text("Video Browser"));
tab.setClosable(false);
tab.setContent(new Input(1));
tabpane.getTabs().addAll(tab);
setTop(new Toolbar(stage));
setCenter(tabpane);
}
}
final class Input extends VBox {
Input(int id) {
HBox hbox = new HBox();
TextField videoTitle = new TextField("video_title");
TextArea description = new TextArea( "video_description");
Button share = new Button("share");
Button unshare = new Button("unshare");
setPadding(new Insets(5,10,10,5));
setAlignment(Pos.TOP_CENTER);
hbox.getChildren().addAll(videoTitle, new Text(" Creator: " + " Date: " + " Views: " + " "));
if(true) {
videoTitle.setEditable(true);
description.setEditable(true);
if(true) {
hbox.getChildren().add(share);
} else { hbox.getChildren().add(unshare); }
}
getChildren().addAll(hbox, description);
}
}
final class Toolbar extends HBox {
protected Toolbar(Stage stage) {
Button close = new Button("close");
close.setOnAction((ActionEvent e) -> { stage.close(); });
setAlignment(Pos.CENTER_LEFT);
getChildren().addAll(close);
}
}
非常感谢,

此问题仅发生在Mac而非Windows(未经测试的Linux)上。修复是降级到符合JavaFX 2.2的最大化窗口,因为JavaFX 8中的setMaximized()也不兼容Mac。
使用找到的here代码修改start方法:
@Override public void start(Stage stage) {
Scene scene = new Scene(new Group());
scene.setRoot(new BuildLayout(stage));
Screen screen = Screen.getPrimary();
Rectangle2D bounds = screen.getVisualBounds();
stage.setTitle("Application Name");
stage.setScene(scene);
stage.setX(bounds.getMinX());
stage.setY(bounds.getMinY());
stage.setWidth(bounds.getWidth());
stage.setHeight(bounds.getHeight());
stage.show();
}
使用可见和闪烁的插入符号生成全屏应用程序。
