用 inputEdit->MaximumWidth() 试试，MinimumSize 可能为0

ComponentControl()

我用的carbide c++ 新建的 UI工程。。里面没有container类，所以我在view类的construt里创建的，你说的这2个方法我没看到有啊

参考..\S60Ex目录下Editor例子

[/Quote]

从你的描述看，你说的View就是一个UI自己建的Container类，你看看这个View是不是继承自CCoeControl,是的话就对了，那么接下来你只要在这个类中增加ComponentControl()、CountComponentControls()两个方法，具体：
TInt CtestEditAppView::CountComponentControls() const
{
return 1;
}


CCoeControl* CtestEditAppView::ComponentControl(TInt aIndex) const
{
switch ( aIndex )
{
case 0:
return iEdit;
default:
return NULL;
}

}

感觉没问题，但是就是什么都不显示
