GWT 单元列表水平

Question

有人知道如何使 CellList 水平定向吗？如果可能的话，请使用UiBinder，但这不是必需的。

Answer 1

遵循 Thomas Broyer 的建议 on the google-web-toolkit group ，和How to style GWT CellList? ，我们可以将新的 CSS 资源注入(inject)到 CellList 构造函数中。

用于获取水平格式的 CSS MyCellList.css:

/* This file is based on the CSS for a GWT CellList:
 * https://gwt.googlesource.com/gwt/+/master/./user/src/com/google/gwt/user/cellview/client/CellList.css
 * The primary purpose is to arrange for the <div> elements that contain each cell to be laid out inline (horizontally).
 */

/* Using inline-block, following Thomas Broyer's recommendations (with link to justification) here:
 * https://groups.google.com/forum/#!topic/google-web-toolkit/rPfCO5H91Rk
 */
.cellListEvenItem {
    display: inline-block;
    padding: 5px;
}

.cellListOddItem {
    display: inline-block;
    padding: 5px;
}

定义一个新资源，如下所示:

public interface MyCellListResource extends CellList.Resources {
  public static MyCellListResource INSTANCE = GWT.create(MyCellListResource.class);
  interface MyCellListStyle extends CellList.Style {}

  @Override
  @Source({CellList.Style.DEFAULT_CSS, "MyCellList.css"})
  MyCellListStyle cellListStyle();
}

注入(inject)新样式，并将其传递给 CellList 的构造函数:

    MyCellListResource.INSTANCE.cellListStyle().ensureInjected();

    CellList<Fare> cellList = new CellList<Fare>(cell, MyCellListResource.INSTANCE);

请注意，新样式出现在 CellList 的 DEFAULT 样式之后的级联中，因此您只需将所需的修改放入 MyCellList.css 中即可。
