单击焦点管理员的按钮

Question

我正在编写有关Arduino的应用程序，在MovieClip中，应用程序中有很多按钮。我可以使用键盘或鼠标单击任何一个，一切正常。但是该应用程序将使用数组中的控件。例如，如果数据[5] = 100，则应按下选项卡键盘按钮。如果数据[5] = 600，则应按Enter。目前，按TAB打开了Focusmanager。下次单击时，FocusManager移至下一个按钮。但是，如果数据[5] = 600，当我单击MovieClip中的按钮时，我会遇到错误。 3个按钮（BTN1，BTN2，BTN3）在主要阶段。 该代码运行良好，

this[BtnCurentName].dispatchEvent(new MouseEvent(MouseEvent.CLICK, true, false));

3个按钮（BTN4，BTN5，BTN6）在MovieClip“ prop”内。我只能这样按下它们。

this[BtnCurentName].dispatchEvent(new MouseEvent(MouseEvent.CLICK, true, false));

这是我的测试代码。

            fm.setFocus( this ); //# manually set your button as default //# fm.setFocus( your button );
            
            this.myBtnFocus = fm.getFocus(); //# update the reference to know currently focused

如何确定按钮的位置在哪个MovieClip中，以便我可以按下它？

尝试：

public function onFocusedBtn (event:FocusEvent) :void 
{
    if(event.target.parent.name == "root2") 
    {
        this.BtnParent = event.target.parent.name;
        this.BtnName = event.target.name;
        trace (">> Got TAB ... Focus is now changed to : " + this.BtnName)
    }
    else 
    {
        this.BtnParent = event.target.parent.name;
        this.BtnName = event.target.name;
        trace (">> Got TAB ... with Parent ... Focus is now changed to : " + this.BtnParent + "." + this.BtnName);
    }
    return;
}

然后在您的函数渲染中可以检查：

//# press mouse click (Enter)
if ( this.Data[5] > 950 )
{
    if(this.BtnParent == "root2")
    {
        trace (">> Name for Click is : " + this.BtnName);
        this[this.BtnName].dispatchEvent(new MouseEvent(MouseEvent.CLICK, true, false));
    }
    else 
    {
        trace (">> Name for Click is : " + this.BtnParent + "." +this.BtnName);
        this[this.BtnParent][this.BtnName].dispatchEvent(new MouseEvent(MouseEvent.CLICK, true, false));
    }
    this.chkBtn = true;

} 

已解决。我得到了如此痕迹

>> Got TAB ... Focus is now changed to : Btn1
>> Name for Click is : Btn1
>> Got Click ... Button name is : Btn1
>> Got TAB ... Focus is now changed to : Btn2
>> Name for Click is : Btn2
>> Got Click ... Button name is : Btn2
>> Got TAB ... Focus is now changed to : Btn3
>> Name for Click is : Btn3
>> Got Click ... Button name is : Btn3
>> Got TAB ... with Parent ... Focus is now changed to : Prop.Btn4
>> Name for Click is : Prop.Btn4
>> Got Click ... Button name is : Btn4
>> Got TAB ... with Parent ... Focus is now changed to : Prop.Btn5
>> Name for Click is : Prop.Btn5
>> Got Click ... Button name is : Btn5
>> Got TAB ... with Parent ... Focus is now changed to : Prop.Btn6
>> Name for Click is : Prop.Btn6
>> Got Click ... Button name is : Btn6
