TGListView layout problems

ROOT
1

I have the following problem using TGListView:
There is an overlapp between the container window and the header window.
I typed:
{
TGListView* listView = new TGListView(hFrame1, (int)(w0.8), h, kSunkenFrame);
TString name(“Name”);
listView->SetHeaders(1);
listView->SetHeader(name.Data(), kTextCenterX, kTextLeft, 0);
TGLVContainer cont = new TGLVContainer(listView, (int)(w0.8) - 10, h,
kSunkenFrame, 0xFFFFFFFF);
listView->SetContainer(cont);
listView->SetViewMode(kLVDetails);
TString test(“Test”);
TGLVEntry entry = new TGLVEntry(cont, test, test);
cont->AddItem(entry);
}
I can’t see the headers. When am typing the other way around first adding the TGLVEntry and then the headers am cannot see the first entry in my list.
