Ext，锁定（冻结）复选框列（CheckboxSelectionModel），可多选

 

 普通的CheckboxSelectionModel也可也锁定，但是在锁定的那边全选按钮不好用了

 

//var sm = new Ext.grid.CheckboxSelectionModel();
//可锁定复选框列
var smLock = new Ext.grid.CheckboxSelectionModel({
	singleSelect : false,
	handleMouseDown : function(g, rowIndex, e) {
		if (e.button !== 0 || this.isLocked()) {
			return;
		}
		var view = this.grid.getView();
		if (e.shiftKey && !this.singleSelect
		&& this.last !== false) {
			var last = this.last;
			this.selectRange(last, rowIndex, e.ctrlKey);
			this.last = last;
			view.focusRow(rowIndex);
		} else {
			var isSelected = this.isSelected(rowIndex);
			if (isSelected) {
				this.deselectRow(rowIndex);
			} else if (!isSelected || this.getCount() > 1) {
				this.selectRow(rowIndex, true);
				view.focusRow(rowIndex);
			}
		}
	},
	isLocked : Ext.emptyFn,
	initEvents : function() {
		Ext.grid.CheckboxSelectionModel.superclass.initEvents.call(this);
		this.grid.on('render', function() {
			var view = this.grid.getView();
			view.mainBody.on('mousedown',
			this.onMouseDown, this);
			Ext.fly(view.lockedInnerHd).on('mousedown',
			this.onHdMouseDown, this);
		}, this);
	}
});

//锁定
smLock.lock();

//cm.setLocked(1,true);
