使用gridpanel时我们有时需要给设置autoHeight:true,但这时如果表格的宽度大于它的容器的宽度,多余的内容就会被隐藏而不会出现横向的滚动条,费了老大劲儿才找到了解决办法,方法就是给gridpanel的option config添加如下属性:
- layout : function() {
- if (!this.mainBody) {
- return; // not rendered
- }
- var g = this.grid;
- var c = g.getGridEl();
- var csize = c.getSize(true);
- var vw = csize.width;
- if (!g.hideHeaders && (vw < 20 || csize.height < 20)) { // display:
- // none?
- return;
- }
- if (g.autoHeight) {
- this.el.dom.style.width = "100%";
- this.el.dom.style.overflow = "auto";
- this.el.dom.firstChild.style.overflow = "visible";
- this.el.dom.firstChild.style.cssFloat = "left";
- this.el.dom.firstChild.firstChild.style.cssFloat = "left";
- this.el.dom.firstChild.firstChild.nextSibling.style.cssFloat = "left";
- this.el.dom.firstChild.firstChild.firstChild.style.overflow = "visible";
- this.el.dom.firstChild.firstChild.nextSibling.style.overflow = "visible";
- } else {
- this.el.setSize(csize.width, csize.height);
- var hdHeight = this.mainHd.getHeight();
- var vh = csize.height - (hdHeight);
- this.scroller.setSize(vw, vh);
- if (this.innerHd) {
- this.innerHd.style.width = (vw) + 'px';
- }
- }
- if (this.forceFit) {
- if (this.lastViewWidth != vw) {
- this.fitColumns(false, false);
- this.lastViewWidth = vw;
- }
- } else {
- this.autoExpand();
- this.syncHeaderScroll();
- }
- this.onLayout(vw, vh);
- }
- }
解决过程中遇到了好多问题,如header的背景不全,不是所有的列都能resize(已经设置了resizable:true),所以可能还有很多问题我没有发现。如果谁发现有什么问题,希望不吝赐教。

又发现了一个简单的方法比上边效果好多了,嘿嘿
