我正在使用维基文章Font icons in Vaadin 7.2中所述的自定义字体图标集。一切正常。
但是,如果我使用声明性UI,我无法使其正常工作。
到目前为止,这是我的代码:
<vaadin-panel caption="..." style-name="..." icon="fonticon://IcoCustom/58884" size-full>
更新
允许的语法:
font://INDUSTRY
(不推荐使用的语法,假设FontAwesome字体图标)fonticon://FontAwesome/f275
(字体系列/代码点,十六进制。十进制值不允许)fonticon://MyFonticon/e900
(有关设置自定义字体图标,请参阅@ Morfic的回答)不是否有效:
fonticon://INDUSTRY
fonticon://FontAwesome/INDUSTRY
答案 0 :(得分:4)
注意:在Vaadin 7.7.3上测试
1)按icomoon中的建议去Using font-icons wiki article并仅选择1个图标,主页(注意分配的代码e900
,这是我们的意思稍后使用。):
2)根据同一教程复制fonts
文件夹内容,但将所有文件重命名为myfont*
:
3)创建主题文件。请注意,维基文章和关于@import
路径的Vaadin docs theme-font section之间存在差异,正确的是来自文档的文章:
@include font(IcoMoon, '../../fonticondemo/fonts/icomoon');
@include font(MyFontFamily, '../../../../mytheme/fonts/myfontfamily');
<强> styles.scss 强>
@import "mytheme.scss";
@include font(myfont, '../../../../mytheme/fonts/myfont');
/* This file prefixes all rules with the theme name to avoid causing conflicts with other themes. */
/* The actual styles should be defined in mytheme.scss */
.mytheme {
@include mytheme;
}
<强> mytheme.scss 强>
@import "../valo/valo";
@mixin mytheme {
@include valo;
}
3)然后创建了设计文件和组件,没什么花哨的,只是一个带按钮的布局:
<强>的java 强>
@DesignRoot
public class MyDeclarativeComponent extends VerticalLayout {
public MyDeclarativeComponent() {
Design.read(this);
}
}
html (请注意使用的e900
代码)
<!DOCTYPE html>
<html>
<body>
<com_example_declarative_font-my-declarative-component>
<vaadin-button icon="fonticon://myfont/e900" plain-text>My button</vaadin-button>
</com_example_declarative_font-my-declarative-component>
</body>
</html>
4)可选枚举,从FontAwesome
public enum MyFont implements FontIcon {
HOME(0xe900);
public static final String FONT_FAMILY = "myfont";
private int codepoint;
private MyFont(int codepoint) {
this.codepoint = codepoint;
}
public String getMIMEType() {
throw new UnsupportedOperationException(FontIcon.class.getSimpleName() + " should not be used where a MIME type is needed.");
}
public String getFontFamily() {
return FONT_FAMILY;
}
public int getCodepoint() {
return this.codepoint;
}
public String getHtml() {
return GenericFontIcon.getHtml(FONT_FAMILY, this.codepoint);
}
public static MyFont fromCodepoint(final int codepoint) {
for (MyFont f : values()) {
if (f.getCodepoint() == codepoint) {
return f;
}
}
throw new IllegalArgumentException("Codepoint " + codepoint + " not found in FontAwesome");
}
}
5)基本UI
实施:
@Theme("mytheme")
@PreserveOnRefresh
@SpringUI(path = "/")
@Title("Vaadin demo app")
public class MyUi extends UI {
@Override
protected void init(VaadinRequest request) {
Layout content = new VerticalLayout();
content.setSizeFull();
setContent(content);
content.addComponent(new MyDeclarativeComponent());
}
}
6)结果:
7)奖金 - 打印组件的声明格式:您可以通过至少2种简单的方式来实现这一目标
a)Design.write(this, System.out);
b)Vaadin debug mode - 使用附带的工具将设计打印到控制台
