JFace 可编辑的TreeViewer和TableViewer

Hexise — Thu, 04 Jan 2007 07:29:00 GMT

向已有的TreeViewer和TableViewer上添加编辑功能，可以使用CellEditor和CellModifier�?/p>

CellEditor定义了某个列被编辑时昄��的外观，它可以是文本框、下拉列表框或单选框�Q�也可以自己定义�?/p>

通常使用的CellEditor的子�c�d��是：CheckboxCellEditor、ComboBoxCellEditor和TextCellEditor�?br />CellEditor一般用数组来保存，如果某个列不需要编辑，则可��该列的CellEditor设�ؓnull�?br />当CellEditor的数�l�定义完后，卛_��利用setCellEditors(CellEditor[] editors)�Ҏ��该数组讄��到对应的TreeViewer或TableViewer中去。例如：

    CellEditor[] cellEditors = new CellEditor[ 5 ];
    cellEditors[ 0 ] = new TextCellEditor(tableViewer.getTable());
    cellEditors[ 1 ] = null ;
    cellEditors[ 2 ] = new ComboBoxCellEditor(tableViewer.getTable(), new String[]{ " first " , " second " , " third " , " forth " });
    cellEditors[ 3 ] = new CheckboxCellEditor(tableViewer.getTable());
    cellEditors[ 4 ] = new CustomizedTextCellEditor(tableViewer.getTable());
    tableViewer.setCellEditors(cellEditors);

其中CustomizedTextCellEditor是自定义的CellEditor�Q�避免了讄��value旉��成的空指针异常�?br />

protected class CustomizedTextCellEditor extends TextCellEditor{
    public CustomizedTextCellEditor(Composite parent){
        super(parent);
    }
    protected void doSetValue(Object value) {
        if(value == null)
            return;
        super.doSetValue(value);
    }
}

CellEditor负责外观�Q�它对要�~�辑的模型信息一无所知。所以jface中引入了ICellModifier接口�Q�将model与CellEditor联系在一赗��ؓ了确定在CellModifier中的列，需要定义columnProperties的String[]数组�Q�用以区分不同列对应的不同属性。��用setColumnProperties(String[] columnProperties)讄��该属性集�?/p>

ICellModifier定义了三个接口方法：

public boolean canModify(Object element, String property);
该方法判断何时该列可以被�~�辑。其中element是对应的model。返回true表示此时该列可以被编辑�?/p>

public Object getValue(Object element, String property);
该方法一般在activateCellEditor()时调用，用于讑֮�CellEditor的初始倹{��其中element是对应的model�?/p>

此处虽然可以�q�回Object�c�d��的引用，但是使用旉��心�Q�特定的CellEditor仅接受特定类型的Value。比如：
TextCellEditor对应String�c�d��的Value�Q?br />ComboBoxCellEditor对应Integer�c�d��的Value�Q?br />CheckBoxCellEditor对应Boolean�c�d��的Value�Q?br />若返回了不适合的Value对象�Q�则会抛出AssertionFailedException�?/p>

public void modify(Object element, String property, Object value);
该方法执行保存修攏V��一般在saveEditorValue之类的方法中调用。此处的element不再是model�Q�而是Item�c�d��的引用。取用对应的模型�Q�需要��?(Item) element).getData()�Ҏ��。一般此处的value��|��也就是当前CellEditor的Value��|��使用CellEditor.getValue()得到。另外，在执行完更改后，需要刷新对应的TableViewer或TreeViewer�Q��做出的更新可见�?br />

GEF�~�辑器的区域及滚动条

Hexise — Fri, 29 Dec 2006 05:16:00 GMT

GEF�~�辑器是构架在Draw2D的FigureCanvas上的,而FigureCanvas是swt中Canvas的子�c?

当得到FigureCanvas之后,��可以得到GEF�~�辑器的区域和GEF�~�辑器内部画布的大小:

�~�辑器区域大��?FigureCanvas.getBounds();
�q�是�q�用了FigureCanvas是Canvas子类的特�?调用SWT的Canvas的getBounds()�Ҏ��,卌��用Control的getBounds()�Ҏ��.

��d��大小:FigureCanvas.getContents.getBounds();
�q�是�q�用了IFigure的getBounds()�Ҏ��, �q�两个区域矩形不可�؜�?

若要触发GEF�~�辑器的滚动条操�?仅需调用FigureCanvas的scrollToX(int hOffset)和scrollToY(int vOffset)卛_��.

获取FigureCanvas的方法也比较��?通过EditPart.getViewer()获得EditPartViewer,一般情况下EditPartViewer的Control��是FigureCanvas.

列出代码如下:

FigureCanvas canvas = (FigureCanvas)EditPart.getViewer().getControl();
canvas.scrollToX( 500 );
canvas.scrollToY( 600 );
System.out.println(canvas.getBounds());
System.out.println(canvas.getContents().getBounds());

eclipse创徏Image�Ҏ��

Eclipse插�g如何��h��资源��理�?

最�q�项目中出现了一个bug,提示是Resource can not sync with file system.是文件系�l�不同步的问�?需要手动刷��C��下资源管理器.

��h��资源��理器调用方�?

RefreshLocal

public void refreshLocal(int depth, IProgressMonitor monitor)
throws CoreException

Refreshes the resource hierarchy from this resource and its children (to the specified depth) relative to the local file system. Creations, deletions, and changes detected in the local file system will be reflected in the workspace's resource tree. This resource need not exist or be local.
This method may discover changes to resources; any such changes will be reported in a subsequent resource change event.

If a new file or directory is discovered in the local file system at or below the location of this resource, any parent folders required to contain the new resource in the workspace will also be created automatically as required.

This method is long-running; progress and cancellation are provided by the given progress monitor.

Parameters:
depth - valid values are DEPTH_ZERO, DEPTH_ONE, or DEPTH_INFINITE
monitor - a progress monitor, or null if progress reporting is not desired
Throws:
CoreException - if this method fails. Reasons include:
Resource changes are disallowed during certain types of resource change event notification. See IResourceChangeEvent for more details.
OperationCanceledException - if the operation is canceled. Cancelation can occur even if no progress monitor is provided.
See Also:
DEPTH_ZERO, DEPTH_ONE, DEPTH_INFINITE, IResourceRuleFactory.refreshRule(IResource)

该方法位于org.eclipse.core.resources.IResource

我的调用�Ҏ��?

ResourcesPlugin.getWorkspace().getRoot().refreshLocal(IResource.DEPTH_INFINITE, monitor);

可以使用GC�cȝ��getAdvanceWidth(char ch)获取当前字符所占的像素宽度.

getAdvanceWidth

public int getAdvanceWidth(char ch)

Returns the advance width of the specified character in the font which is currently selected into the receiver.

The advance width is defined as the horizontal distance the cursor should move after printing the character in the selected font.

Parameters:

ch - the character to measure

Returns:

the distance in the x direction to move past the character before painting the next

Throws:

SWTException -

ERROR_GRAPHIC_DISPOSED - if the receiver has been disposed

可以如下面的�E�序使用该函�?

public static int getStringWidth(String string, Control control) {

    int width = 0;
    GC gc = new GC(control);
   for (int i = 0; i < string.length(); i++) {
        char c = string.charAt(i);
        width += gc.getAdvanceWidth(c);
    }

    gc.dispose();
    return width;
}

或者更通用�?其中string是目标字�W�串,font是你要设�l�字�W�串的字体对�?

public static int getStringWidth(String string, Font font){
    int width = 0;
    Shell shell = new Shell();
    Label label = new Label(shell, SWT.NONE);
    label.setFont(font);
    GC gc = new GC(label);
    for(int i=0;i<string.length();i++){
          char c = string.charAt(i);
          width += gc.getAdvanceWidth(c);
    }
    gc.dispose();
    shell.dispose();
    return width;
}
