Form.Load (gb.qt4)
Static Sub Load ( [ Parent As Control ] )
创建窗体的隐藏缺省实例。
注意*只要缺省实例需要被嵌入一个workspace或另一个窗体，就应该使用该函数。
This function is called Load to recall the Visual Basic™ terminology.
Old VB user, do not use this 方法 on an already instanciated form. This is useless, at it will
create an hidden form that you will never use, and that will prevent your program to terminate!
