Ext.tree.Column
サムネイルを表示する通常の葉のアイコンの代わりに拡張を終了しました。
これが私のコードです:
Ext.define('Grafik.component.tree.Column2', {
extend: 'Ext.tree.Column',
alias: 'widget.treecolumn2',
thumbnailsServiceUrl:'',
cellTpl: [
'<tpl for="lines">',
'<img src="{parent.blankUrl}" class="{parent.childCls} {parent.elbowCls}-img ',
'{parent.elbowCls}-<tpl if=".">line<tpl else>empty</tpl>"/>',
'</tpl>',
'<img src="{blankUrl}" class="{childCls} {elbowCls}-img {elbowCls}',
'<tpl if="isLast">-end</tpl><tpl if="expandable">-plus {expanderCls}</tpl>"/>',
'<tpl if="checked !== null">',
'<input type="button" role="checkbox" <tpl if="checked">aria-checked="true" </tpl>',
'class="{childCls} {checkboxCls}<tpl if="checked"> {checkboxCls}-checked</tpl>"/>',
'</tpl>',
'<img src="{loginUrl}" class="{childCls} {baseIconCls} ',
'{baseIconCls}-<tpl if="leaf">leaf<tpl else>parent</tpl> {iconCls}"',
'<tpl if="icon">style="background-image:url({icon})"</tpl>/>',
'<tpl if="href">',
'<a href="{href}" target="{hrefTarget}" class="{textCls} {childCls}">{value}</a>',
'<tpl else>',
'<span class="{textCls} {childCls}">{value}</span>',
'</tpl>'
],
treeRenderer: function (value, metaData, record, rowIdx, colIdx, store, view) {
var me = this,
cls = record.get('cls'),
renderer = me.origRenderer,
data = record.data,
parent = record.parentNode,
rootVisible = view.rootVisible,
lines = [],
parentData;
if (cls) {
metaData.tdCls += ' ' + cls;
}
while (parent && (rootVisible || parent.data.depth > 0)) {
parentData = parent.data;
lines[rootVisible ? parentData.depth : parentData.depth - 1] =
parentData.isLast ? 0 : 1;
parent = parent.parentNode;
}
return me.getTpl('cellTpl').apply({
record: record,
baseIconCls: me.iconCls,
iconCls: data.iconCls,
icon: data.icon,
checkboxCls: me.checkboxCls,
checked: data.checked,
elbowCls: me.elbowCls,
expanderCls: me.expanderCls,
textCls: me.textCls,
leaf: data.leaf,
expandable: record.isExpandable(),
isLast: data.isLast,
blankUrl: Ext.BLANK_IMAGE_URL,
loginUrl: data.leaf ? me.thumbnailsServiceUrl + record.get('Login') : Ext.BLANK_IMAGE_URL,
href: data.href,
hrefTarget: data.hrefTarget,
lines: lines,
metaData: metaData,
// subclasses or overrides can implement a getChildCls() method, which can
// return an extra class to add to all of the cell's child elements (icon,
// expander, elbow, checkbox). This is used by the rtl override to add the
// "x-rtl" class to these elements.
childCls: me.getChildCls ? me.getChildCls() + ' ' : '',
value: renderer ? renderer.apply(me.origScope, arguments) : value
});
}
});
使用法は次のようになります。
{
text: 'Users',
dataIndex: 'Name',
hideable: false,
width: 260,
xtype: 'treecolumn2',
sortable: true,
resizable: false,
thumbnailsServiceUrl: window.appUrl + 'api/Thumbnails/'
}
api/Thumbnails

簡単な解決策、それが誰かに役立つことを願っています:)
