在复合材料中包裹阿贝尔

我有ScrolledComposite，只允许垂直滚动。 （heighthint = 400）。

在这个ScrolledComposite中，我有另一个CompositeA（滚动时高度可能超过400）来存储所有其他小部件。

我有一个很长的标签（启用了SWT.WRAP）。但它不是包装，而是始终以单行显示。我希望这个标签根据其父级（CompositeA）

的宽度进行换行

我忘了添加CompositeA为GridLayout的{​​{1}}列{。}}。

这是我的代码：

makeColumnsEqualWidth = true

如果你运行它，你可以看到绿色的scrolledcomposite和一个红色的复合材料。我希望红色复合宽度相对填充到scrolledcomposite的宽度，而不需要硬编码public void createPartControl(Composite parent) { // TODO Auto-generated method stub Display display = parent.getDisplay(); toolkit = new FormToolkit(display); form = toolkit.createForm(parent); form.setText("ABC"); Composite body = form.getBody(); TableWrapLayout layout = new TableWrapLayout(); layout.numColumns = 2; body.setLayout(layout); Label header1 = toolkit.createLabel(body, "ABC: "); Font font = new Font(display, "Arial", 11, SWT.BOLD); header1.setFont(font); Label header2 = toolkit.createLabel(body, "XYZ", SWT.WRAP); font = new Font(display, "Arial", 11, SWT.NONE); header2.setFont(font); TableWrapData wd = new TableWrapData(TableWrapData.FILL_GRAB); header2.setLayoutData(wd); form.getBody().setBackground( form.getBody().getDisplay() .getSystemColor(SWT.COLOR_WIDGET_BACKGROUND)); // Scrolled composite ScrolledComposite sc = new ScrolledComposite(body, SWT.BORDER_SOLID | SWT.V_SCROLL); sc.setAlwaysShowScrollBars(true); sc.setBackground(new Color(display, 50,255,155)); wd = new TableWrapData(TableWrapData.FILL); wd.heightHint = 360; wd.colspan = 2; wd.grabHorizontal = false; sc.setLayoutData(wd); sc.setLayout(new TableWrapLayout()); Composite innerComposite = toolkit.createComposite(sc); sc.setContent(innerComposite); innerComposite.setLayout(new TableWrapLayout()); innerComposite.setBackground(new Color(display, 255,50,50)); Section section = toolkit.createSection(innerComposite, Section.DESCRIPTION | Section.TITLE_BAR | Section.EXPANDED); wd = new TableWrapData(TableWrapData.FILL); wd.maxWidth = 600; // don't want to hardcode this value section.setLayoutData(wd); section.setText("Section"); section.setDescription("A not so long description......................"); // Composite for Section Composite sectionClient = toolkit.createComposite(section); layout = new TableWrapLayout(); layout.numColumns = 2; layout.makeColumnsEqualWidth = true; sectionClient.setLayout(layout); toolkit.createButton(sectionClient, "Button 1", SWT.RADIO); Label rightDesc = toolkit .createLabel( sectionClient, "A very long long long long long long long long long long long long long long long long long long long long desc that needs wrapping", SWT.WRAP); font = new Font(display, "Arial", 10, SWT.ITALIC); rightDesc.setFont(font); wd = new TableWrapData(); wd.rowspan = 2; rightDesc.setLayoutData(wd); Combo comboDropDown = new Combo(sectionClient, SWT.DROP_DOWN | SWT.BORDER); comboDropDown.setText("DDL"); comboDropDown.add("1"); comboDropDown.add("2"); comboDropDown.add("3"); Label lineBreak = toolkit.createSeparator(sectionClient, SWT.SEPARATOR | SWT.HORIZONTAL); wd = new TableWrapData(TableWrapData.FILL); wd.colspan = 2; lineBreak.setLayoutData(wd); /***********************/ toolkit.createButton(sectionClient, "Button 2", SWT.RADIO); Label rightDesc2 = toolkit .createLabel( sectionClient, "A long long long long long long long long long long long long long long long long long long long long desc that needs wrapping", SWT.WRAP); font = new Font(display, "Arial", 10, SWT.ITALIC); rightDesc2.setFont(font); wd = new TableWrapData(TableWrapData.FILL); wd.rowspan = 3; rightDesc2.setLayoutData(wd); toolkit.createLabel(sectionClient, "Desc", SWT.WRAP); toolkit.createText(sectionClient, "hello world", SWT.NONE); section.setClient(sectionClient); innerComposite.pack(); } 。

我在布局中遇到了同样的问题，并找到了this有用的答案。

由于＆＃39;它不是bug，它是一个功能＆＃39;请在评论＃19 here中尝试此答案。

我为我的Label使用以下代码行。

Label tip = new Label(shell, SWT.WRAP | SWT.BORDER | SWT.LEFT);
final GridData data = new GridData(SWT.HORIZONTAL, SWT.TOP, true, false, 1, 1);
tip.setLayoutData(data);
tip.setText("Here stands my long, long and much more longer text...");

尝试在创建标签时添加SWT.WRAP。它对我有用。

Label label = new Label(parent, SWT.WRAP);

令人惊讶的是，TableWrapLayout经理不会指望水平滚动的复合材料。要使用Form工具包上的布局。我刚刚做了一个代码示例，可以在上面做些什么。

public void createPartControl(Composite parent) {
    // TODO Auto-generated method stub

    Display display = parent.getDisplay();

    toolkit = new FormToolkit(display);
    form = toolkit.createForm(parent);
    form.setText("ABC");

    Composite body = form.getBody();

    TableWrapLayout layout = new TableWrapLayout();
    layout.numColumns = 2;
    body.setLayout(layout);

    Label header1 = toolkit.createLabel(body, "ABC: ");
    Font font = new Font(display, "Arial", 11, SWT.BOLD);
    header1.setFont(font);

    Label header2 = toolkit.createLabel(body, "XYZ", SWT.WRAP);
    font = new Font(display, "Arial", 11, SWT.NONE);
    header2.setFont(font);

    TableWrapData wd = new TableWrapData();      
    header2.setLayoutData(wd);

    body.setBackground(body.getDisplay().getSystemColor(SWT.COLOR_WIDGET_BACKGROUND));

    // Scrolled composite
    Composite sc = toolkit.createComposite(body, SWT.BORDER_SOLID | SWT.V_SCROLL);
    sc.setBackground(new Color(display, 50,255,155));
    layout = new TableWrapLayout();    
    sc.setLayout(layout);

    wd = new TableWrapData(TableWrapData.FILL_GRAB); 
    wd.heightHint = 360;
    wd.colspan = 2;
    sc.setLayoutData(wd);

    Composite innerComposite = toolkit.createComposite(sc);

    layout = new TableWrapLayout();
    innerComposite.setLayout(layout);
    innerComposite.setBackground(new Color(display, 255,50,50));

    wd = new TableWrapData(TableWrapData.FILL_GRAB); 
    innerComposite.setLayoutData(wd);

    Section section = toolkit.createSection(innerComposite,
            Section.DESCRIPTION | Section.TITLE_BAR | Section.TWISTIE | Section.EXPANDED);

    section.setText("Section");
    section.setDescription("A not so long description......................");

    wd = new TableWrapData(TableWrapData.FILL_GRAB);
    // wd.maxWidth = 600; // don't want to hardcode this value
    section.setLayoutData(wd);


    // Composite for Section
    Composite sectionClient = toolkit.createComposite(section);
    layout = new TableWrapLayout();
    layout.numColumns = 2;
    // layout.makeColumnsEqualWidth = true;
    sectionClient.setLayout(layout);
    section.setClient(sectionClient);

    wd = new TableWrapData(TableWrapData.FILL_GRAB); 
    sectionClient.setLayoutData(wd);

    Label rightDesc = toolkit.createLabel(sectionClient,
                    "A very long long long long long long long long long long long long long long long long long long long long desc that needs wrapping",
                    SWT.WRAP);
    font = new Font(display, "Arial", 10, SWT.ITALIC);
    rightDesc.setFont(font);
    wd = new TableWrapData();
    wd.colspan = 2;
    rightDesc.setLayoutData(wd);

    Combo comboDropDown = new Combo(sectionClient, SWT.DROP_DOWN | SWT.BORDER);
    comboDropDown.setText("DDL");
    comboDropDown.add("1");
    comboDropDown.add("2");
    comboDropDown.add("3");

    Label lineBreak = toolkit.createSeparator(sectionClient, SWT.SEPARATOR | SWT.HORIZONTAL);
    wd = new TableWrapData(TableWrapData.FILL_GRAB);
    lineBreak.setLayoutData(wd);
        //
        //    /***********************/
        //
    Button button1 = toolkit.createButton(sectionClient, "Button 1", SWT.RADIO);
      wd = new TableWrapData();
      wd.colspan = 2;
      button1.setLayoutData(wd);

    Button button2 = toolkit.createButton(sectionClient, "Button 2", SWT.RADIO);
      wd = new TableWrapData();
      wd.colspan = 2;
      button2.setLayoutData(wd);

    Label rightDesc2 = toolkit.createLabel(sectionClient,
                    "A long long long long long long long long long long long long long long long long long long long long desc that needs wrapping",
                    SWT.WRAP);
    font = new Font(display, "Arial", 10, SWT.ITALIC);
    rightDesc2.setFont(font);
    wd = new TableWrapData();
    wd.colspan = 2;
    rightDesc2.setLayoutData(wd);

    Label desc = toolkit.createLabel(sectionClient, "Desc:");
    Text hello = toolkit.createText(sectionClient, "hello world");
    wd = new TableWrapData(TableWrapData.FILL_GRAB);
    hello.setLayoutData(wd);
}

如果您要包装长文本标签，SWT.WRAP是不够的。如果未在布局中指定 widthHint ，则标签默认不会包装其文本。这对我有用：

Label label = new Label(parent, SWT.WRAP);
label.setText("very very long text....");
GridData gd = new GridData(SWT.FILL, SWT.TOP, true, false, 1, 1);
gd.widthHint = 200;
label.setLayoutData(gd);
