我使用GridData在SWT中创建了对话框：
Label1：ComboBox
Label2：TextBox1
Label3：TextBox2
checkbox1 Label4
checkbox2 Label5
根据ComoBox选择的值，我需要将TextBox2替换为DateChooserCombo或将DateChooserCombo替换为TextBox2。
下面是我的类实现，其方法createTextBox在加载对话框时创建TextBox2。调用setDatePicker更改组合框值。请在下面的课程中提供有关我们如何实现它的帮助。提前谢谢。

对组合框的选择更改事件实现的方法，即setControl（templateType.getItem（templateType.getSelectionIndex（）），templateTypeGroup）;
它在处理旧控件之前采用布局和显示细节，并通过传递旧控件的细节来创建新控件。
public void setControl(String value, Group templateTypeGroup) {
Object grd = null;
Point pt = null;
Rectangle rct = null;
if(TableTemplateConfigConstants.dateItems.contains(value) && null != defaultValueText){
grd = defaultValueText.getLayoutData();
pt = defaultValueText.getLocation();
rct = defaultValueText.getBounds();
defaultValueText.dispose();
cleanControls();
createDateControl(templateTypeGroup,grd,pt,rct,value);}}
public void createDateControl(Composite templateTypeGroup, Object data, Point pt, Rectangle rectangle,String value){
**enumDateChooser = new DateChooserCombo(
templateTypeGroup, SWT.BORDER | CDT.DROP_DOWN
| CDT.DATE_SHORT);
enumDateChooser.setFormatter(new DateFormatter(
ITableDataConstants.DATE_FORMAT_TABLE_VIEWER));
enumDateChooser.setLayoutData((GridData)data);
if(null != pt && null != rectangle){
enumDateChooser.setLocation(pt);
enumDateChooser.setBounds(rectangle);
}
enumDateChooser.setLocation(pt)**
try {
if(!isEdit){
if (TableTemplateConfigConstants.endDateLst.contains(value)) {
enumDateChooser
.setValue(checkFormat(TableTemplateConfigConstants.endDate));
DateFormat formatter = new SimpleDateFormat(TableTemplateConfigConstants.DATE_FORMAT_TABLE_VIEWER);
setDefaultVal(formatter.format(checkFormat(enumDateChooser.getText())));
} else if (TableTemplateConfigConstants.effectiveDate
.contains(value)) {
enumDateChooser.setValue(new Date());
DateFormat formatter = new SimpleDateFormat(TableTemplateConfigConstants.DATE_FORMAT_TABLE_VIEWER);
setDefaultVal(formatter.format(checkFormat(enumDateChooser.getText())));
} else if (null != getDefaultVal() && !getDefaultVal().isEmpty()) {
enumDateChooser.setValue(checkFormat(getDefaultVal()));
setDefaultVal(value);
}
}else{
enumDateChooser
.setValue(checkFormat(getDefaultVal()));
}
} catch (ParseException e1) {
PALogger.logError("Unable to parse date",
PAEventCategory.OTHERS, Activator.PLUGIN_ID,e1);
}
setDateDecoration(false);
enumDateChooser.addModifyListener(new ModifyListener() {
@Override
public void modifyText(ModifyEvent e) {
System.out.println(enumDateChooser.getText());
if (null != enumDateChooser && !enumDateChooser.isDisposed()
) {
setDateDecoration(true);
}
setDateCheckBoxes();
}
});
}
