使用 CSS 更改节点设计
using CSS to change node design
我不知道我在向节点添加 CSS 样式时做错了什么。
我有一个主应用程序 window。然后我单击菜单项,另一个模式 window 打开如下(ModalWindow
扩展 Stage
):
FXMLLoader loader = new FXMLLoader(getClass().getResource(CONSTANTS.ROOT_USER_EDIT.string));
BorderPane editPane;
try {
editPane = new BorderPane(loader.load());
ModalWindow editWindow = new ModalWindow(Main.mainStage, editPane, "Edit user");
//its new stage with new scene, so we need to load this file again
editWindow.getScene().getStylesheets().add(getClass().getResource(CONSTANTS.CSS_PATH.string).toExternalForm());
UserData userData = (UserData)usersTable.getSelectionModel().getSelectedItem();
UserEditWindowController userEditWindowController = loader.getController();
userEditWindowController.fillWithData(userData);
editWindow.initModality(Modality.APPLICATION_MODAL);
editWindow.showAndWait();
} catch (IOException exception) {
ExceptionDialog exceptionDialog = new ExceptionDialog("Couldn't load UserEditWindow",exception);
exceptionDialog.showAndWait();
}
已添加此 CSS 文件:
#greenInfoTip {
-fx-graphic-text-gap: 20;
-fx-font-size: 44.0px ;
-fx-background: green;
-fx-background-color: rgb(128,255,128);
}
我尝试在根控制器中执行此操作 class:
infoTip.setId("greenInfoTip");
但没有效果。我做错了什么吗?
编辑 ItachiUchiha 正是它的样子:
方法在 UserEditWindowController 中 class:
@FXML
private void buttSaveAction(ActionEvent event){
//check if login and password doesn't contain spaces and is 4-16 characters long
String login = textFLogin.getText();
String password = textFPassword.getText();
boolean hasLoginWhiteSpace = isContainingWhiteSpace(login);
boolean hasPasswordWhiteSpace = isContainingWhiteSpace(password);
boolean isLoginMoreThan3 = (login.length() > 3)? true : false;
boolean isLoginLessThan17 = (login.length() < 17)? true : false;
boolean isPasswordMoreThan3 = (password.length() > 3)? true : false;
boolean isPasswordLessThan17 = (password.length() < 17)? true : false;
InfoTip infoTip = new InfoTip();
if( hasLoginWhiteSpace == false){
if( hasPasswordWhiteSpace == false ){
if( isLoginMoreThan3 == true && isLoginLessThan17 == true){
if( isPasswordMoreThan3 == true && isPasswordLessThan17 == true ){
//========login and password are correct
String query = "UPDATE users SET login = ?, password = ? WHERE employee_id = ?;";
try( Connection connection = Main.dataSource.getConnection() ){
try( PreparedStatement preparedStatement = connection.prepareStatement(query) ){
preparedStatement.setString(1, login);
preparedStatement.setString(2, password);
preparedStatement.setInt(3, currentUser.getiD());
preparedStatement.executeUpdate();
currentUser.setLogin(login);
currentUser.setPassword(password);
infoTip.getInfoTip().setId("greenInfoTip");
infoTip.showTip((Button)event.getSource(), "Saved");
}
}catch(Exception exception){
ExceptionDialog exceptionDialog = new ExceptionDialog("Error while loading data from database",exception);
exceptionDialog.showAndWait();
};
}else{ //password has less than 4 or more than 16 characters
infoTip.showTip(textFPassword, "no more than 16 and no less than 4 characters!");
}
}else{ //login has less than 4 or more than 16 characters
infoTip.showTip(textFLogin, "no more than 16 and no less than 4 characters!");
}
}else{ //password has white space
infoTip.showTip(textFPassword, "no spaces!");
}
}else{ //login has white space
infoTip.showTip(textFLogin, "no spaces!");
}
}
public class InfoTip {
private Tooltip infoTip;
public InfoTip(){
infoTip = new Tooltip();
}
private static Point2D getNodePos(Node node){ //getting node coordination on screen
Scene nodeScene = node.getScene();
final Point2D windowPos = new Point2D(nodeScene.getWindow().getX(), nodeScene.getWindow().getY());
final Point2D scenePos = new Point2D(nodeScene.getX(), nodeScene.getY());
final Point2D nodePos = node.localToScene(0.0, 0.0);
final Point2D nodePosOnScreen = new Point2D(windowPos.getX() + scenePos.getX() + nodePos.getX(),
windowPos.getY() + scenePos.getY() + nodePos.getY());
return nodePosOnScreen;
}
public void showTip(Node node, String text){
Point2D nodePosOnScreen = getNodePos(node);
infoTip = new Tooltip(text);
infoTip.setFont(new Font(15));
infoTip.setOpacity(0.9);
infoTip.setAutoFix(true);
infoTip.setAutoHide(true);
infoTip.show(node, nodePosOnScreen.getX()-30, nodePosOnScreen.getY() - 40);
}
public Tooltip getInfoTip(){
return infoTip;
}
}
问题在于
infoTip = new Tooltip(text);
里面 howTip(Node node, String text)
。
您正在用一个新对象覆盖带有 id 的旧工具提示。尝试使用
infoTip.setText(text);
