How to close modal window extjs when clicking on mask?

问题

If I create a modal window:

Ext.define('myWindow', {
    extend: 'Ext.Container',
    alias: 'widget.myWindow',
    floating: true,
    modal: true,
    listeners:
        'onMaskClick???': { close the window }
    .....
}

How do I know when a user has clicked on the mask outside the window? In Sench Touch, there is a config hideOnMaskTap that lets me specify. What is the event/config for extJS?

Tramway's case (sort of) works on modal or non modal windows. But not in case child components like the boundlist of a combobox float outside the windows boundaries.

However if you use modal windows anyway you can listen for a click event on the mask like this.

Ext.define('myWindow', {
    extend: 'Ext.window.Window',
    alias: 'widget.myWindow',
    floating: true,
    modal: true,

    initComponent: function () {
        var me = this;
        me.callParent(arguments);
        me.mon(Ext.getBody(), 'click', function(el, e){
            me.close(me.closeAction);
        }, me, { delegate: '.x-mask' });
    }
});

You can listen all click events, then check if click position is out of the window

Ext.define('myWindow', {
    extend: 'Ext.Container',
    alias: 'widget.myWindow',
    floating: true,
    modal: true,

    initComponent: function () {
        this.initEvents();
        this.callParent();
    },

    initEvents: function () {
        //make sure your window is rendered and have sizes and position
        if(!this.rendered) {
            this.on('afterrender', this.initEvents, this, {single: true});
            return;
        }

        this.mon(Ext.getBody(), 'click', this._checkCloseClick, this);
    }

    _checkCloseClick: function (event) {
        var cx = event.getX(), cy = event.getY(),
            box = this.getBox();

        if (cx < box.x || cx > box.x + box.width || cy < box.y || cy > box.y + box.height) {
            //clean up listener listener
            this.mun(Ext.getBody(), 'click', this._checkCloseClick, this);
            this.close();
        }
    }
}

You can try this also:

Ext.getBody().on('click', function(e, t){
    var el = win.getEl();

    if (!(el.dom === t || el.contains(t))) {
        win.close();
    }
});

I found adding a listener to the body and checking css classes felt a little hackey to me. You can actually override the private method _onMaskClick of Ext.ZIndexManager (see, completely not hackey). Which allows you to add your own configuration parameter (and even event) to all windows.

Ext.define('MyApp.ux.ZIndexManager_maskClick', {
  override: 'Ext.ZIndexManager',

  _onMaskClick: function ()
  {
    if (this.front)
    {
      var allowed = this.front.fireEvent('maskclick', this.front, this.mask);

      if (allowed !== false && this.front.closeOnMaskClick)
        this.front.close();
    }
    return this.callParent(arguments);
  },
});
