本文整理了Java中com.google.gwt.user.client.ui.Image.getWidth()方法的一些代码示例，展示了Image.getWidth()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Image.getWidth()方法的具体详情如下：
包路径：com.google.gwt.user.client.ui.Image
类名称：Image
方法名：getWidth

Image.getWidth介绍

[英]Gets the width of the image. When the image is in the unclipped state, the width of the image is not known until the image has been loaded (i.e. load event has been fired for the image).
[中]获取图像的宽度。当图像处于未剪辑状态时，在加载图像之前（即，已为图像触发加载事件），图像的宽度是未知的。

代码示例

private void setImages(ImageAdapter images, boolean useLeafImages) {
 this.images = images;
 this.useLeafImages = useLeafImages;
 if (!useLeafImages) {
  Image image = images.treeLeaf().createImage();
  image.getElement().getStyle().setProperty("visibility", "hidden");
  RootPanel.get().add(image);
  int size = image.getWidth() + TreeItem.IMAGE_PAD;
  image.removeFromParent();
  indentValue = (size) + "px";
 }
}

   * Returns the image width.
