extjs tree 节点图标
extjs tree(树)换节点图标及去掉图标后去掉空白部分
/*ext/resources/ext-all.css 817行 闭合文件夹图标*/
.x-tree-node-collapsed .x-tree-node-icon{
background-image:url(../images/default/tree/folder.gif);
}
/*ext/resources/ext-all.css 7134行 打开文件夹图标*/
.x-tree-node-expanded .x-tree-node-icon
{
background-image: url(../images/default/tree/folder-open.gif);
}
/*ext/resources/xtheme-blue.css 812行 节点图标*/
.x-tree-node-leaf .x-tree-node-icon{
background-image:url(../images/default/tree/leaf.gif);
}
/*ext/resources/ext-all.css 3220行 图标所在位置设置*/
.x-tree-node-collapsed .x-tree-node-icon, .x-tree-node-expanded .x-tree-node-icon, .x-tree-node-leaf .x-tree-node-icon
{
border: 0 none;
height: 18px; /*空白部分高*/
margin: 0;
padding: 0;
vertical-align: top;
width: 16px;/*空白部分宽*/
background-position: center;
background-repeat: no-repeat;
}
想换的图标只需修改相应的图标，想去掉图标只需将图标所在位置设置：height:0px;width: 0px.
如果只想修改某个tree的样式，添加个cls就可以了。
