【问题描述】:
我使用以下代码创建了一个包含两个输入字段的对话框。
public class CCIDDialog extends TitleAreaDialog {
private Text ccidText;
private Text descriptionText;
private String CCID;
private String description;
public CCIDDialog(Shell parentShell) {
super(parentShell);
}
public void create() {
super.create();
setTitle(_title);
setMessage("Bitte geben Sie die CCID "+firstchar+"xxxxxxx und eine Beschreibung ein (max. 7-stellig): ", IMessageProvider.INFORMATION); }
@Override
protected Control createDialogArea(Composite parent) {
Composite area = (Composite) super.createDialogArea(parent);
Composite container = new Composite(area, SWT.NONE);
container.setLayoutData(new GridData(GridData.FILL_BOTH));
GridLayout layout = new GridLayout(2, false);
container.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true));
container.setLayout(layout);
createCCID(container);
createDescription(container);
return area;
}
private void createCCID(Composite container) {
Label lbtFirstName = new Label(container, SWT.NONE);
lbtFirstName.setText("CCID (ohne "+firstchar+"): ");
GridData dataCCID = new GridData();
dataCCID.grabExcessHorizontalSpace = true;
dataCCID.horizontalAlignment = GridData.FILL;
ccidText = new Text(container, SWT.BORDER);
ccidText.setLayoutData(dataCCID);
}
private void createDescription(Composite container) {
Label lbtLastName = new Label(container, SWT.NONE);
lbtLastName.setText("Beschreibung: ");
GridData dataDescription = new GridData();
dataDescription.grabExcessHorizontalSpace = true;
dataDescription.horizontalAlignment = GridData.FILL;
descriptionText = new Text(container, SWT.BORDER);
descriptionText.setLayoutData(dataDescription);
}
@Override
protected boolean isResizable() {
return true;
}
// save content of the Text fields because they get disposed
// as soon as the Dialog closes
private void saveInput() {
CCID = ccidText.getText();
description = descriptionText.getText();
}
@Override
protected void okPressed() {
saveInput();
super.okPressed();
}
public String getCCID() {
return CCID;
}
public String getDescription() {
return description;
}
}
有没有办法验证 ccidtext? 如果用户输入超过 7 个字符,他必须收到通知并且不能继续对话。我在互联网上阅读了很多内容,但找不到解决此问题的方法。
非常感谢您的帮助。
