(操作脚本3)在上下文菜单打开时获取单击位置

时间:2013-08-02 13:08:06

标签: flash actionscript-3

我正在尝试通过右键单击并使用AS3和flash打开ContextMenu来解决我需要获取点击位置的问题。

我尝试过使用MouseEvent.Context_Menu:

mapSprite.addEventListener(MouseEvent.CONTEXT_MENU, OnContextMenuOpening);

这会在右键单击时触发,但上下文菜单不再打开。

我也尝试过使用MosueEvent.Right_Click:

mapSprite.addEventListener(MouseEvent.RIGHT_CLICK, OnContextMenuOpening);

点击右键+点击但会阻止上下文菜单打开。

任何人都对此问题有任何见解?

不是我认为理想的东西,但这会让你真正理解。创建一个新的菜单对象(具有所有内置菜单选项),并向其添加一个事件监听器。

var my_menu:ContextMenu = new ContextMenu();
contextMenu = my_menu;
my_menu.addEventListener(ContextMenuEvent.MENU_SELECT, rightClicker)

function rightClicker(e:ContextMenuEvent):void {
    trace(e);
}

Atriace的答案基本上是正确的,但它并没有直接解决实际问题,我立即意识到这一点。以下是他的解决方案的一点扩展:

private function setupSample():void
{
     // NOTE: Sample assumes that I have a TextField named _myTextField defined elsewhere.
     _myTextField.contextMenu = new ContextMenu();
     _myTextField.contextMenu.addEventListener(ContextMenuEvent.MENU_SELECT, hContextMenuSelect);
}

private function hContextMenuSelect(pEvent:ContextMenuEvent):void
{
      var x:Number = pEvent.mouseTarget.mouseX;
      var y:Number = pEvent.mouseTarget.mouseY;
}

使用此方法,实际上将显示上下文菜单,但您也可以访问鼠标单击的坐标。只需将ContextMenuEvent.MENU_SELECT侦听器直接添加到上下文菜单中,然后从侦听器参数中提取该点。请注意,鼠标位置可通过ContextMenuEvent获得。

以下代码正常运行。我创建了一个300x300的形状并在其上分配了上下文菜单。鼠标位置将显示在左上角的文本框中。

package {
import flash.ui.ContextMenuItem;
import flash.display.MovieClip;
import flash.events.MouseEvent;
import flash.text.TextFormat;
import flash.display.Sprite;
import flash.text.TextField;
import flash.ui.ContextMenu;
import flash.display.Shape;

public class Main extends Sprite {
    private var cm_item1:ContextMenuItem = new ContextMenuItem("Menu Item 1");
    private var cm_item2:ContextMenuItem = new ContextMenuItem("Menu Item 2");
    private var cm_item3:ContextMenuItem = new ContextMenuItem("Menu Item 3");
    private var cm_item4:ContextMenuItem = new ContextMenuItem("Menu Item 4");
    private var txtFormat:TextFormat = new TextFormat("Arial", 20, 0x000000);
    private var c_menu:ContextMenu = new ContextMenu();
    private var map_mc:MovieClip = new MovieClip();
    private var txt:TextField = new TextField();
    private var bg:Shape = new Shape();

    public function Main():void {
        bg.graphics.beginFill(0x00ffff);
        bg.graphics.drawRect(0, 0, 300, 300);
        bg.graphics.endFill();
        map_mc.addChild(bg);
        map_mc.x = map_mc.y = 100;
        addChild(map_mc);

        txt.background = 0xffffff;
        txt.border = true;
        txt.defaultTextFormat = txtFormat;
        txt.width = 200;
        addChild(txt);

        c_menu.hideBuiltInItems();
        c_menu.customItems.push(cm_item1, cm_item2, cm_item3, cm_item4);
        map_mc.contextMenu = c_menu;

        map_mc.addEventListener(MouseEvent.CONTEXT_MENU, cmFx);
    }

    private function cmFx(e:MouseEvent):void {
        txt.text = "x: " + mouseX + " y: " + mouseY; 
    }

}

}
