Liferay Portal为我们提供了非常灵活的主题风格定制功能,自身带了四种风格的theme,在官方网站上提供了很多风格theme的下载,这无疑大大增强了主题风格定制的功能。但是,我们完全可以开发具有自己风格的theme,这里,我们将讨论怎样来开发个性的theme。
第一步:我们将以现有风格classic为模板文件创建新的theme,我们将新theme命名为coldtear 1、将liferay/html/themes目录下的classic文件夹copy一份副本,并修改副本的文件夹名为coldtea 2、在liferay/web-inf目录下新建liferay-look-and-feel-ext.xml文件,文件liferay-look-and-feel.xml是定义主题风格theme的配置文件,为了加以区分,我们在这里新建了该文件的扩展文件liferay-look-and-feel-ext.xml,该文件内容如下:
<?xml version="1.0"?> <!DOCTYPE look-and-feel PUBLIC "-//Liferay//DTD Look and Feel 4.0.0//EN" "http://www.liferay.com/dtd/liferay-look-and-feel_4_0_0.dtd">
<look-and-feel> <compatibility> <version>4.0.0</version> </compatibility> <company-limit> <company-includes /> <company-excludes /> </company-limit> <theme id="coldtear" name="ColdTear"> <root-path>/html/themes/coldtear</root-path> <templates-path>/html/themes/coldtear/templates</templates-path> <images-path>/html/themes/coldtear/images</images-path> <template-extension>jsp</template-extension> <color-scheme id="01" name="Blue"> <![CDATA[ body-bg=#FFFFFF layout-bg=#FFFFFF layout-text=#000000
layout-tab-bg=#E0E0E0 layout-tab-text=#000000
layout-tab-selected-bg=#6699CC layout-tab-selected-text=#4A517D
portlet-title-bg=#6699CC portlet-title-text=#4A517D
portlet-menu-bg=#B6CBEB portlet-menu-text=#000000
portlet-bg=#FFFFFF
portlet-font=#000000 portlet-font-dim=#C4C4C4
portlet-msg-status=#000000 portlet-msg-info=#000000 portlet-msg-error=#FF0000 portlet-msg-alert=#FF0000 portlet-msg-success=#007F00
portlet-section-header=#094170 portlet-section-header-bg=#ADBDFB
portlet-section-subheader=#405278 portlet-section-subheader-bg=#91AEE8
portlet-section-body=#000000 portlet-section-body-bg=#E2E7FA
portlet-section-body-hover=#FFFFFF portlet-section-body-hover-bg=#AC6CFA
portlet-section-alternate=#000000 portlet-section-alternate-bg=#CFD7FB
portlet-section-alternate-hover=#FFFFFF portlet-section-alternate-hover-bg=#AC6CFA
portlet-section-selected=#7AA0EC portlet-section-selected-bg=#FAFCFE
portlet-section-selected-hover=#00329A portlet-section-selected-hover-bg=#C0D2F7 ]]> </color-scheme> </theme> </look-and-feel>
这里,注意的是修改theme的id和name,以及root-path、templates-path和images-path的路径,这样,我们就可以在主题风格页面看到我们新的theme了。
第二步、分析classic的主题布局的划分 1、打开liferay/html/theme/coldtear/templates目录,该目录下存放着很多jsp文件,打开portal_normal.jsp文件可以看到,该文件是整个页面的主体,通过<liferay-util:include />标签和<%@ include>方法包含了很多jsp文件,其中top.jsp文件定义了头部信息,navigation.jsp定义了导航菜单,bottom.jsp定义了底部语言标签信息,而页面的主体信息是由<liferay-theme:box />标签定义的,top="portlet_top.jsp"定义了portlet的标题栏信息,bottom="portlet_bottom.jsp"定义了portlet下面的阴影线,portlet的内容则是由<liferay-util:include page="<%= Constants.TEXT_HTML_DIR + tilesContent %>" />定义的。所有的css样式信息是定义在css_cached.jsp文件中的。 2、liferay portal的页面定义大部分地方都采用了DIV+CSS的方式,下面将以classic的整个DIV定义框架给出,以说明classic风格的定义方法。
<div id="layout-outer-side-decoration"> <div id="layout-inner-side-decoration"> <div id="layout-box"> <!-- 定义头部信息 top.jsp --> <div id="layout-top-banner"> <div id="layout-user-menu" style="text-align: right;"> <div class="font-small" style="margin-top: 5px;"> <div id="layout-my-places"> <div id="p_p_id_49_" class="portlet-boundary"> <div class="portlet-borderless-container"> </div> </div> </div> </div> </div> </div> <!-- 定义导航菜单 navigation.jsp --> <div id="layout-nav-container"> <div class="layout-nav-tabs-box"> <div class="layout-tab"></div> <div class="layout-tab"></div> <div class="layout-tab-selected"></div> <div class="layout-tab"></div> </div> <div id="layout-global-search"></div> </div> <div class="portlet-bottom-decoration-2"><div><div></div></div></div> <!-- 定义主体portlet信息部分 --> <div id="layout-content-outer-decoration"> <div id="layout-content-inner-decoration"> <div id="layout-content-container"> <div id="layout-column_column-1"> <div id="p_p_id_73_INSTANCE_9Q28_" class="portlet-boundary"> <div class="portlet-container"> <!-- 定义portlet标题栏信息 portlet-top.jsp --> <div class="portlet-header-bar" id="portlet-header-bar_73_INSTANCE_9Q28" onmouseover="PortletHeaderBar.show(this.id)" onmouseout="PortletHeaderBar.hide(this.id)"> <div class="portlet-wrap-title"> </div> <div class="portlet-small-icon-bar" style="display: none;"> </div> </div> <!--&nb
