我正在使用GridLayout嘗試製作標籤自動增長而不隱藏任何內容。這裏有一個簡單的代碼來測試:每次我按下按鈕標籤的文字變得越大,但只有當我調整水平的窗口後,我得到正確的佈局。 有沒有辦法解決這個問題,而不必調整窗口的大小? 我想我已經嘗試了所有的財產,我仍然無法得到這個工作,這讓我瘋狂!佈局問題:自動增長標籤(SWT)
這是我得到
這是應該的

label.setText("New Label");

list.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true, 1, 1));

感謝您的時間。
解決這些變化:
Button button = new Button(shell, SWT.NONE);
button.addSelectionListener(new SelectionAdapter() {
public void widgetSelected(SelectionEvent arg0) {
label.setText(label.getText() + " " + label.getText());
shell.layout(); // ADDED THIS
}
});
button.setText("New Button");
label = new Label(shell, SWT.WRAP);
// SET HORIZONTAL GRAB ON LABEL (FIRST TRUE IN GridData CONSTRUCTOR)
label.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, false, 1, 1));
label.setText("New Label");
是的!就是這樣!,非常感謝! – 2010-08-17 14:13:17
