您好我是java的初学者,我的表格大小有问题。
在first picture上你可以看到尺寸非常好,但是当我点击按钮时,桌子的大小会缩小picture two)。
感谢您的帮助:)
protected void createContents() {
...
gridData = new GridData();
gridData.horizontalAlignment = SWT.FILL;
gridData.horizontalSpan = 2;
gridData.grabExcessHorizontalSpace = true;
table = new Table(shell, SWT.BORDER | SWT.FULL_SELECTION);
table.setLayoutData(gridData);
table.setHeaderVisible(true);
table.setLinesVisible(true);
TableColumn columnProduct = new TableColumn(table, SWT.NONE);
columnProduct.setText("Product");
TableColumn columnKey = new TableColumn(table, SWT.NONE);
columnKey.setText("Key");
for (int i = 0; i < 2; i++)
{
table.getColumn(i).pack();
}
shell.pack();
shell.open();
}
@Override
public void mouseDown(MouseEvent e) {
TableItem tItem = new TableItem(table, SWT.FILL);
String[] data = { txtProduct.getText(), txtKey.getText()};
tItem.setText(data);
table.pack();
}
答案 0 :(得分:2)
如果您希望根据内容自动调整列数,请在列上使用pack()
,而不是表格:
for (TableColumn column : table.getColumns()) {
column.pack();
}
如果您希望表格使用额外的垂直空间,请相应地设置其gridData
:
...
gridData = new GridData();
gridData.horizontalAlignment = SWT.FILL;
gridData.horizontalSpan = 2;
gridData.grabExcessHorizontalSpace = true;
// add these:
gridData.verticalAlignment = SWT.FILL;
gridData.grabExcessVerticalSpace = true;
