On Mouse Entered 交换按钮位置的方法
On Mouse Entered Method to swap Button position
我想开发一个鼠标输入的方法,使用 FXML 和 JavaFX 实时交换两个按钮的位置,不幸的是我对它很陌生。 Relocate(x,y)、get/setLayoutX/Y 和低于 get/setTranslateX/Y 都会抛出 IllegalArgumentEceptions,在堆栈跟踪中没有更多可理解的信息。为了获取和设置实时位置交换,首选按钮 属性 是什么?
@FXML protected void neinHover (ActionEvent evt){
double jTmpX, jTmpY, nTmpX, nTmpY;
nTmpX = neinButton.getTranslateX();
nTmpY = neinButton.getTranslateY();
jTmpX = jaButton.getTranslateX();
jTmpY = jaButton.getTranslateY();
jaButton.setTranslateX(nTmpX);
jaButton.setTranslateY(nTmpY);
neinButton.setTranslateX(jTmpX);
neinButton.setTranslateY(jTmpY);
}
我想你想要这样的东西:
FXML:
<fx:root onMouseClicked="#swap" type="Pane" xmlns:fx="http://javafx.com/fxml/1" xmlns="http://javafx.com/javafx/8">
<children>
<Button fx:id="b1" mnemonicParsing="false" text="1" />
<Button fx:id="b2" layoutX="90.0" mnemonicParsing="false" text="2" />
</children>
</fx:root>
控制器:
public class MockPane extends Pane {
@FXML
private Button b1;
@FXML
private Button b2;
public MockPane() {
FXMLLoader fxmlLoader = new FXMLLoader(getClass().getResource(
"MockPane.fxml"));
fxmlLoader.setRoot(this);
fxmlLoader.setController(this);
try {
fxmlLoader.load();
} catch (IOException e) {
throw new RuntimeException(e);
}
}
@FXML
private void swap() {
double b1x = b1.getLayoutX();
double b1y = b1.getLayoutY();
double b2x = b2.getLayoutX();
double b2y = b2.getLayoutY();
b1.setLayoutX(b2x);
b1.setLayoutY(b2y);
b2.setLayoutX(b1x);
b2.setLayoutY(b1y);
}
}
应用程序:
public class MockApp extends Application {
public static void main(String[] args) {
Application.launch(args);
}
@Override
public void start(Stage stage) throws Exception {
MockPane root = new MockPane();
Scene scene = new Scene(root, 200, 100);
stage.setScene(scene);
stage.show();
}
}
