【问题描述】：

我目前正在尝试禁用可选择/可编辑/或将 textInput 更改为动态以获得我想要的结果。

我有一个带有下拉菜单和文本输入区域的自定义数据网格。但是，如果我的 Model # 列中没有数据，我不想在相应的 PurchasePrice 单元格中允许任何条目。

col1 = new DataGridColumn("Model");
    col1.headerText = "Model #";
    c2.consumables_dg.addColumn(col1);
    col1.width = 60;
    col1.editable = false;
    col1.sortable = false;
    col1.cellRenderer = AlternatingRowColors_editNum_PurchasePrice;
col1 = new DataGridColumn("PurchasePrice");
    col1.headerText = "Purchase Price";
    c2.consumables_dg.addColumn(col1);
    col1.width = 60;
    col1.editable = false;
    col1.sortable = false;
    col1.cellRenderer = AlternatingRowColors_editNum_PurchasePrice;

我尝试了 AlternatingRowColors_editNum_PurchasePrice 中的各种项目，但目前似乎没有任何效果。请查看我在 if(__enbaled) 的 else 语句中尝试过的内容

package
    import flash.text.TextFormat;
    import flash.text.TextFormatAlign;
    import fl.controls.TextInput;
    import flash.text.TextFieldType;
    import flash.events.Event;
    import fl.controls.listClasses.ListData;
    import fl.controls.listClasses.ICellRenderer;

public class AlternatingRowColors_editNum_PurchasePrice extends TextInput implements ICellRenderer

    protected var _data:Object;
    protected var _listData:ListData;
    protected var _selected:Boolean;
    private var __enabled:Boolean = false;
    public static var _stage;
    public static var _alignment;
    private var tf:TextFormat;

    public function AlternatingRowColors_editNum_PurchasePrice()
    
        tf = new TextFormat();
        if(__enabled)
                if(_alignment == 2)
                    tf.align = TextFormatAlign.RIGHT;
                else if(_alignment == 1)
                    tf.align = TextFormatAlign.CENTER;
                else
                    tf.align = TextFormatAlign.LEFT;
                
            restrict = "0-9.";
            addEventListener(Event.CHANGE, textChange);

        else
            //this.selectable = false; // did not work
            //textField.selectable = false; // did not work
            //textField.type = dynamic; // did not work
            //textField.type = TextFieldType.DYNAMIC; // did not work
            //this.mouseEnabled = false; // did not work
            //this.tabEnabled = false; // did not work
            //textField.mouseEnabled = false; // did not work
            //textField.tabEnabled = false; // did not work
            //selectable = false; // did not work
            //this.selectable = false; // did not work
            //_enabled = false; // did not work
            //-----------------------------------------------------------
            //   *** Corresponding Entry to enable was placed above ***
            //-----------------------------------------------------------
        
        super();
    

    public function textChange(Event):void
        //trace(_data.Discount);
        _data.PurchasePrice = text;
    

    public function get data():Object
    
        return _data;
    

    public function set data(value:Object):void
    
        _data = value;
        text = value.PurchasePrice;

        if(value.Model != "") __enabled = true;

        if (value.id % 2 == 0) 
            setStyle("upSkin", AlternateColor1 );
         else 
            setStyle("upSkin", AlternateColor2 );
        
    

    public function get listData():ListData
    
        return _listData;
    

    public function set listData(value:ListData):void
    
        _listData = value;
    

    public function get selected():Boolean
    
        return _selected;
    

    public function set selected(value:Boolean):void
    
        _selected = value;
    

    public function setMouseState(state:String):void
    
    
    override protected function drawLayout():void
    
        textField.setTextFormat(tf);
        super.drawLayout();
    

我只是以错误的方式接近这个吗？与其尝试停止鼠标、制表符或将文本字段转换为动态，我应该尝试其他方法以获得所需的结果吗？

谢谢， jc

【参考方案1】：

最简单的方法是更改​​TextField 类型本身，然后更改它的selectable 属性：

//disable input
tf.selectable = false;
tf.type = TextFieldType.DYNAMIC;

//enable input
tf.selectable = true;
tf.type = TextFieldType.INPUT;

也不要忘记根据您的字段的需要/需要设置mouseEnabled 和tabEnabled 属性。

【讨论】：

如果我像你一样使用TextFieldType，它会给我一个错误。我用这段代码而不是你的代码更正了它：tf.type = "dynamic"; 和 txtAnswer.type = "input"; 可能对其他人有用；）

【参考方案2】：

确保将类/页面/框架顶部的 TextFieldType 导入为：

import flash.text.TextFieldType;
