SmartGWT模态窗口 [英] SmartGWT modal window

问题描述

我有模态窗口的问题。我将这两个方法称为 setIsModal（true）和 setShowModalMask（true）但为什么我的窗口不是模态？ / b>

以下是代码：

 窗口summaryWindow = new Window（） ; 
 summaryWindow.setWidth（950）; 
 summaryWindow.setHeight（620）; 
 summaryWindow.centerInPage（）; 
 summaryWindow.setCanDragReposition（false）; 
 summaryWindow.setIsModal（true）; 
 summaryWindow.setShowModalMask（true）; 
 summaryWindow.setShowMinimizeButton（false）; 
 summaryWindow.setTitle（Example）; 
 summaryWindow.addItem（new Button（Example）; 
 summaryWindow.show（）; 
  

code> Window 小部件， setWidth ， setHeight ， centerInPage etc ...

现在必须应用这些属性中的某些属性，然后才将小部件呈现在浏览器&它们中的一些必须在小部件呈现在浏览器的DOM中之后应用。

ShowModalMask（）是一个属性，您可以在渲染窗口小部件之前设置。
centerInPage（）是一个在浏览器& DOM中呈现Window的属性，
$ b

在之后以正确顺序应用属性（ centerInPage（））， ShowModalMask（）在你的情况），以避免这种例外。

I have problem with modal window. I call this two methods setIsModal(true) and setShowModalMask(true) but why my window isn't modal ?

Here is the Code :

Window summaryWindow = new Window();
summaryWindow.setWidth(950);
summaryWindow.setHeight(620);
summaryWindow.centerInPage();
summaryWindow.setCanDragReposition(false);
summaryWindow.setIsModal(true);
summaryWindow.setShowModalMask(true);
summaryWindow.setShowMinimizeButton(false);
summaryWindow.setTitle("Example");
summaryWindow.addItem(new Button("Example");
summaryWindow.show();

解决方案

The exception you're getting is valid. In any GWT related technology, you'll find many API functionalities to set properties of GWT widget. For example, for a Window widget you have, setWidth, setHeight, centerInPage etc...

Now some of these properties MUST be applied before the widget is rendered in DOM of the browser & some of them MUST be applied after the widget is rendered in DOM of the browser.

ShowModalMask() is a property that you can set only before the widget is rendered. centerInPage() is a property that renders Window in DOM of browser & that is the reason you're getting the exception.

Apply properties in a proper order (centerInPage() after ShowModalMask() in your case) to avoid this kind of exception.
