Question

` 一旦我点击按钮，我就会打开gwt DialogBox。鼠标滚动只在打开的对话框上工作，我想让它也适用于父窗口。我尝试使modal =“false”但没有用。请帮忙。

这是示例代码

<g:DialogBox autoHide="false" glassEnabled="true" modal="true" styleName="{style.historyGraphDialogPanel}">
    <g:HTMLPanel >
      <table class="HistoryGraphInteractionTable" ui:field="historyGraphInteractionTable">
        <tbody>
      <tr>
        <td>
          <g:Button ui:field="lastDay">Last Day</g:Button>
          <g:Button ui:field="lastWeek">Last Week</g:Button>
          <g:Button ui:field="lastMonth">Last Month</g:Button>
        </td>
      </tr>
      <tr>
        <td>
          <cdm:HistoryGraphWidget ui:field="graphWidget" />
        </td>
      </tr>
      <tr>
        <td>
          <g:Button ui:field="closeButton">Close</g:Button>
        </td>
      </tr>
    </tbody>
  </table>
</g:HTMLPanel>

.historyGraphDialogPanel {
    background-color: ivory;        
}`

我不知道为什么modal属性在ui.xml中不起作用，但在JAVA中设置模态将解决您的问题。

setModal(false);

以下是示例代码：

MyDialogbox.java：

import com.google.gwt.core.client.GWT;
import com.google.gwt.event.dom.client.ClickEvent;
import com.google.gwt.uibinder.client.UiBinder;
import com.google.gwt.uibinder.client.UiField;
import com.google.gwt.uibinder.client.UiHandler;
import com.google.gwt.uibinder.client.UiTemplate;
import com.google.gwt.user.client.ui.Button;
import com.google.gwt.user.client.ui.DialogBox;
import com.google.gwt.user.client.ui.Widget;

public class MyDialogbox extends DialogBox {

    private static MyUiBinder myUIBinder = GWT.create(MyUiBinder.class);

    @UiTemplate("MyDialogbox.ui.xml")
    interface MyUiBinder extends UiBinder<Widget, MyDialogbox> {
    }

    public MyDialogbox() {
        setWidget(myUIBinder.createAndBindUi(this));
        this.setModal(false);
    }

    @UiField
    Button cancelButton;

    @UiHandler("cancelButton")
    void hideDialogBox(ClickEvent event) {
        hide();
    }

}

MyDialogbox.ui.xml：

<ui:UiBinder xmlns:ui='urn:ui:com.google.gwt.uibinder'
    xmlns:g='urn:import:com.google.gwt.user.client.ui'>

    <g:DialogBox autoHide="true" modal="false">
        <g:caption>
            <b>Caption text</b>
        </g:caption>
        <g:HTMLPanel>
            Body text
            <g:Button ui:field='cancelButton'>Cancel</g:Button>
            <g:Button ui:field='okButton'>Okay</g:Button>
        </g:HTMLPanel>
    </g:DialogBox>
</ui:UiBinder>

如何为g：DialogBox启用父窗口滚动
