Re: [qooxdoo-devel] Automatic blocker setting on opening/closing windows?

[Christian S. <sch...@1u...>]

Hi Cajus,

I would use a listener on "changeVisibility" for my own window class. To 
get the application root use: "qx.core.Init.getApplication().getRoot()".

[code]
qx.Class.define("test.MyWindow",
{
  extend : qx.ui.window.Window,

  construct : function(caption, icon)
  {
    this.base(arguments, caption, icon);
   
    this.setModal(true);
    this.addListener("changeVisibility", this.__onChangeVisibility, this);
  },
 
  members : {
    __onChangeVisibility : function(event)
    {
      var root = qx.core.Init.getApplication().getRoot();
      if (event.getData() === "visible")
      {
        root.setBlockerColor("#73B3D9");
        root.setBlockerOpacity(0.5);
      }
      else {
        root.resetBlockerColor();
        root.resetBlockerOpacity();
      }
    }
  }
});
[/code]

Cheers,
Chris
