表列將不走表視圖的全尺寸在JavaFX

我試圖創建一個表有兩列。 我使用netbeans 7.2中包含的場景生成器。 在我所看到的一切，你需要做的所有例子是表列拖到表，將採取全尺寸的，這不是我的情況屬實。 這是場景生成器生成的fxml文件。 只是爲了清楚我不改變java的表格屬性。表列將不走表視圖的全尺寸在JavaFX

的FXML：當與FXML文檔應用

在JavaFX的2.2+版本的新功能已經使這個答案已經過時了。 FXML set TableView column resize policy：在設置

其使用新FXML特徵，以允許經由FXML設置列大小的FXML基於溶液。

<TableView fx:id="tableView" layoutX="110.0" layoutY="78.0" prefHeight="200.0" prefWidth="396.0"> 
    <columnResizePolicy><TableView fx:constant="CONSTRAINED_RESIZE_POLICY"/></columnResizePolicy> 
    <columns> 
     <TableColumn prefWidth="75.0" text="Column X" /> 
     <TableColumn prefWidth="75.0" text="Column X" /> 
    </columns> 
</TableView>

如果你不使用FXML的TableView中的大小調整政策，仍然可以通過代碼設置爲這個答案定義：

tableView.setColumnResizePolicy(TableView.CONSTRAINED_RESIZE_POLICY);

在你FXML，您所定義的首選寬度將表格設置爲837，並將每列的首選寬度設置爲75.默認情況下，JavaFX列調整大小策略將使列保持其首選寬度。除非您設置新的列大小調整策略，或者將所有列的首選寬度總和設置爲與表格寬度相加，否則不會獲取填充整個表格寬度的表格列。

的JavaFX確實提供了一個機制來modify the default column resizing policy。由列大小調整策略設置爲一個CONSTRAINED_RESIZE_POLICY，每列的寬度之和將被限制在填補的tableview的寬度 - 即使實現代碼如下調整大小或單個列調整。這可能是你想要的行爲。雖然可能有一種方法可以在FXML的tableView上設置CONSTRAINED_RESIZE_POLICY，但我並不知道其中的一種（儘管我在fxml中的技能是基本的 - 所以也許有人更加了解可以使用純fxml完成​​配置）。

你可以做的是定義一個控制器爲您FXML文件，然後配置控制器容量調整政策。以下代碼演示了一個完整的示例（針對JavaFX 2.2b17預覽）。

FXML文件：

<?xml version="1.0" encoding="UTF-8"?> 

<?import java.lang.*?> 
<?import java.util.*?> 
<?import javafx.scene.control.*?> 
<?import javafx.scene.layout.*?> 
<?import javafx.scene.paint.*?> 

<AnchorPane id="AnchorPane" maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="400.0" prefWidth="600.0" xmlns:fx="http://javafx.com/fxml" fx:controller="tableview.TableViewController"> 
    <children> 
    <TableView fx:id="tableView" layoutX="110.0" layoutY="78.0" prefHeight="200.0" prefWidth="396.0"> 
     <columns> 
     <TableColumn prefWidth="75.0" text="Column X" /> 
     <TableColumn prefWidth="75.0" text="Column X" /> 
     </columns> 
    </TableView> 
    </children> 
</AnchorPane>

控制器類：

package tableview; 

import java.net.URL; 
import java.util.ResourceBundle; 
import javafx.fxml.FXML; 
import javafx.fxml.Initializable; 
import javafx.scene.control.TableView; 

/* controller class for the tableview fxml definition */ 
public class TableViewController implements Initializable { 
    @FXML // fx:id="tableView" 
    private TableView<?> tableView; // Value injected by FXMLLoader 

    @Override // This method is called by the FXMLLoader when initialization is complete 
    public void initialize(URL fxmlFileLocation, ResourceBundle resources) { 
    assert tableView != null : "fx:id=\"tableView\" was not injected: check your FXML file 'tableview.fxml'."; 

    // initialize your logic here: all @FXML variables will have been injected 
    tableView.setColumnResizePolicy(TableView.CONSTRAINED_RESIZE_POLICY); 
    } 
}

應用類：

package tableview; 

import java.io.IOException; 
import java.net.URL; 
import javafx.application.Application; 
import javafx.fxml.FXMLLoader; 
import javafx.scene.Scene; 
import javafx.scene.layout.AnchorPane; 
import javafx.stage.Stage; 

/** Main application class for tableview fxml demo application */ 
public class TableViewApplication extends Application { 
    public static void main(String[] args) { launch(args); } 
    @Override public void start(Stage stage) throws IOException { 
    AnchorPane layout = FXMLLoader.load(
     new URL(TableViewApplication.class.getResource("tableview.fxml").toExternalForm()) 
    ); 
    stage.setScene(new Scene(layout)); 
    stage.show(); 
    } 
}

非常感謝@jewelsea你是第一個也是唯一的地方，我找到了控制列重新調整大小的方法。如果我碰到一種方法來從fxml控制表，我會在這裏發佈它。 – raven 2012-07-22 22:03:05

似乎很奇怪我在控制器中添加UI配置。你可以通過在.fxml文件中添加一個XML標籤來做同樣的事情，如以下鏈接所示：http://stackoverflow.com/questions/14095708/fxml-set-tableview-column-resize-policy – gabuzo 2013-01-06 13:13:42

感謝鏈接gabuzo ，我通過回答更新以反映新的JavaFX 2.2功能，該功能現在允許您從FXML定義表的列大小調整策略。 – jewelsea 2013-01-06 22:13:26

如果您使用JavaFX GUI構建器「SceneBuilder 2.0」 - 使用TableView屬性ColumnResizePolicy「constrained-resize」值。
