在按鈕上調整TextField的大小點擊

我試圖調整TextField的大小，點擊了startBtnClick，我似乎無法使其工作。基本上我想按單擊按鈕時縮小字段110單位。在按鈕上調整TextField的大小點擊

在行動事件：

@FXML 
protected void startBtnClick(){ 
    double txtWidth = this.url.getWidth(); 
    this.url.setPrefWidth(txtWidth - 110); 
}

的XML：

<?xml version="1.0" encoding="UTF-8"?> 
<AnchorPane fx:id="anchorPane" minHeight="200.0" minWidth="200.0" prefHeight="600.0" prefWidth="1200.0" styleClass="anchor-pane" xmlns:fx="http://javafx.com/fxml/1" xmlns="http://javafx.com/javafx/2.2" fx:controller="phantom.FXMLDocumentController"> 
    <children> 
     <Button id="beginSurfing" fx:id="quitSurfing" mnemonicParsing="false" onAction="#stopSurfing" prefHeight="29.0" prefWidth="93.00009999999747" text="Quit Surfing" visible="false" AnchorPane.rightAnchor="9.0" AnchorPane.topAnchor="8.0" />

          </stylesheets> 
         </TextField> 
         <Button id="beginSurfing" fx:id="startSurfing" mnemonicParsing="false" onAction="#beginSurfing" prefHeight="29.0" prefWidth="93.00009999999747" text="Start Surfing" AnchorPane.rightAnchor="12.0" AnchorPane.topAnchor="9.0" />

          </font> 
         </Label> 
         <Button id="beginSurfing" fx:id="nextAdBtn" mnemonicParsing="false" onAction="#nextAd" prefHeight="30.000099999997474" prefWidth="94.0" text="Next Ad" visible="false" AnchorPane.rightAnchor="12.0" AnchorPane.topAnchor="8.0" /> 
        </children> 
       </AnchorPane> 
       <!-- 
        The rest of the gird 
        Chopped off for readability 
       --> 
      </children> 
     </GridPane> 
    </children> 
</AnchorPane>

我想'setPrefWidth'是不正確的方法。我會測試並回答 – diegoaguilar

您需要設置按鈕的佈局參數，而不僅僅是首選值。爲了效率和穩定性，Android可以（並經常）覆蓋您的首選值。 – zgc7009

由於您的按鈕處於AnchorPane，你有兩個左，右錨件設置，寬度爲將由這些錨點控制，而不是由prefWidth屬性控制。一個AnchorPane可能不是去，如果你希望能夠動態地調整控制的最佳方式，但你可以做

AnchorPane.setRightAnchor(url, AnchorPane.getRightAnchor(url)+110);
