因爲gridpanel的單元格里的文字太多時候,都由省略號代替,就想實現如題的功能,通過反覆實驗,終於搞定了!直接上代碼:ide
me.on('itemmouseenter', function (view, record, item, index, e, eOpts) { if (view.tip == null) { //這塊判斷很重要,不能每次都建立個tooltip,要不顯示會有問題。 view.tip = Ext.create('Ext.tip.ToolTip', { // The overall target element. target: view.el, // Each grid row causes its own separate show and hide. delegate: view.itemSelector, // Moving within the row should not hide the tip. // trackMouse: false, // Render immediately so that tip.body can be referenced prior to the first show. renderTo: Ext.getBody() }); }; var gridColums = view.getGridColumns(); var column = gridColums[e.getTarget(view.cellSelector).cellIndex]; view.el.clean(); view.tip.update(record.data[column.dataIndex]); });
解釋下:這裏截取主要的代碼,實際中,就是監聽你的表格itemmouseenter這個事件就好了!
效果如圖!
