winform 显示位置发生改变

[cjcy1984001]

GroupCallPanel^ GroupForm = gcnew GroupCallPanel(pCGC);
GroupForm->Focus();//设置焦点
GroupForm->MdiParent = this;
m_FormNum++;
switch(m_FormNum)
{
case 1:
GroupForm->Location = Point(0,0);
//GroupForm->m_location = GroupForm->Location;
break;
case 2:
GroupForm->Location = Point(GroupForm->Width,0);
//GroupForm->m_location = GroupForm->Location;
break;
case 3:
GroupForm->Location = Point(0,GroupForm->Height);
//GroupForm->m_location = GroupForm->Location;
break;
case 4:
GroupForm->Location = Point(GroupForm->Width,GroupForm->Height);
//GroupForm->m_location = GroupForm->Location;
break;
}
GroupForm->Show();

为什么在show的时候，位置发生了改变？GroupForm->Show(); 以前 GroupForm->Location为（301,0），show()
执行后变成了（22.33）

最开始StartPosition属性设置为手动。

GroupForm->StartPosition = FormStartPosition::Manual;
