Image in GWT Button
提问by Maksim
How do I add image to GWT Button or how do I use Mosaic's Buttons to add image. I can't figure out how to use THISexample in my code. What library do I need to add. I have Mosaic Library in my project and I can use it but the example that they have there does not work for me.
如何将图像添加到 GWT 按钮或如何使用 Mosaic 的按钮添加图像。我不知道如何在我的代码中使用这个例子。我需要添加什么库。我的项目中有马赛克库，我可以使用它，但他们在那里的示例对我不起作用。
Thanks
谢谢

If you just want to add an image to a normal GWT Button, then PushButtonis the way to go:
如果您只想将图像添加到普通的 GWT 按钮，那么PushButton是您的最佳选择：
PushButton pushButton = new PushButton(new Image("test.png"));

Alternatively, you this method.
或者，你这个方法。
Button editRow = new Button("Edit Row");
editRow.setHTML(("<img border='0' src='rowEdit.Png' />");
I have found the the PushButton appears to have a problem with calculating its x, y click point correctly, which the normal button does not have.
我发现 PushButton 似乎在正确计算其 x、y 单击点时存在问题，而普通按钮则没有。

PushButton does not have the same behavior, and you have a prettier solution than creating yourself an image tag :
PushButton 没有相同的行为，您有一个比创建自己的图像标签更漂亮的解决方案：
Image img = new Image("whatever.jpg");
Button button = new Button();
button.getElement().appendChild(img.getElement());

Just set the HTML img tag inside the button as:
只需将按钮内的 HTML img 标记设置为：
Button btn = new Button("<img src='image.png'/>");

Just use CSS and style in the image. Something like this should make the image appear before the button text:
只需在图像中使用 CSS 和样式。这样的事情应该使图像出现在按钮文本之前：
background-image: url("/yourimage.png");
background-repeat: no-repeat;
height: 20px;
width: 20px;
