我有 ScrolledComposite
,它只允许垂直滚动。 (heighthint = 400
)。
在这个 ScrolledComposite 中,我有另一个 CompositeA
(滚动高度可能超过 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
)。但它不是换行,而是始终显示在一行中。我希望此标签根据其父级 (CompositeA
)
我忘了补充一点,这个 CompositeA
是一个 2 列的 GridLayout
,makeColumnsEqualWidth = true
。
这是我的代码:
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();
}
如果你运行它,你可以看到一个绿色的滚动复合体和一个红色的复合体。我希望红色复合宽度相对于滚动复合宽度填充,而无需硬编码 maxWidth = 600
。
最佳答案
我的布局中有同样的问题,发现 this有用的答案。
因为“这不是错误,它是一个功能”请尝试评论 #19 中的这个答案 here .
我将以下代码行用于我的标签。
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...");
