BUIW高手们 我快疯了 快来帮帮我把！万分感谢

[wolfcao8]

我最近在学习BUIW，需要用BUIW 写一个游戏，工程建立好了 但是想建立一个菜单，LISTWIDGET里的ITEM怎么也显示不出来。
谁能来帮帮我看看 我写的东西有什么问题。


int nErr = SUCCESS;
IWidget *piw = NULL;
IWidget *pisw = 0;
IWidget *pisw1 = 0;
IVectorModel *pIVectMod;
IBitmap *pib = 0;


// create the root form
nErr = ISHELL_CreateInstance(me->pIShell, AEECLSID_ROOTFORM, (void **)&me->piRootForm);

// create the form
if(SUCCESS == nErr) {
nErr = ISHELL_CreateInstance(me->pIShell, AEECLSID_FORM, (void **)&me->piForm);
}

nErr += ISHELL_CreateInstance(me->pIShell,AEECLSID_VECTORMODEL,(void**)&pIVectMod);


//wade
nErr = ISHELL_CreateInstance(me->pIShell, AEECLSID_LISTWIDGET, (void **)&piw);
if(SUCCESS == nErr)
{
IWIDGET_SetItemHeight(piw,30);
IWIDGET_SetItemWidth(piw,240);
IWIDGET_SetBGColor(piw, rgbFrmBg);
nErr = IFORM_SetWidget(me->piForm, WID_FORM, piw);//把LISTWIDGET挂到FORM下

}

//建立一个STATICWIDGET来作为LIST的一个ITEM
nErr = ISHELL_CreateInstance(me->pIShell, AEECLSID_STATICWIDGET, (void **)&pisw);
if(SUCCESS == nErr)
{

IWIDGET_SetFGColor(pisw, rgbFrmBg);
IWIDGET_SetFlags(pisw, IDF_ALIGN_LEFT);
IWIDGET_SetText(pisw, awchText, TRUE);
IWIDGET_SetModel(pisw,(IModel*)pIVectMod);
IDECORATOR_SetWidget((IDecorator *)piw, pisw);//将TATICWIDGET挂到LISTWIDGET上面
}

RELEASEIF(pIVectMod);
RELEASEIF(pisw);
RELEASEIF(piw);


// set some keys and titles

IFORM_SetText(me->piForm, FID_TITLE, awchTitle);
IFORM_SetText(me->piForm, FID_SOFTKEY1, awchSoftkey1);
IFORM_SetText(me->piForm, FID_SOFTKEY2, awchSoftkey2);

// push the form to the root form
nErr = IROOTFORM_PushForm(me->piRootForm, me->piForm);

// if there have been no failures up to this point then return success
return nErr;

这个是我按照你的方法最新写的CODE 但是还是不能显示 各位能不能帮我看看为什么 再这里跪谢了
int nErr=0;
IBitmap *pib = 0;

WExtent oldwe;

}

// get the device bitmap

(1)vectormodel应该与listwidget相联系，而不应该是与staticwidget相联系。
(2)要设置listwidget的大小，才能显示。

你怎么没用到容器啊 ，我先它ITEM INSERT到容器再把容器PushForm，我也是新手，多指教！谢谢

[voidsun]

代码可真不是一般的乱，要让ListWidget正确显示，要设置Item的高度及宽度
用下面两个接口函数试一试：
IWIDGET_SetItemHeight
IWIDGET_SetItemWidth
