问题描述

我在选项卡控件内部使用带有CListCtrl的CTabCtrl，我需要知道在切换选项卡时如何删除列标题.我已经尝试过CListCtrl :: DeleteColumn()，但似乎没有效果.我也尝试过...

I''m using a CTabCtrl with a CListCtrl inside the tab control, I need to know how to remove the column headings when I switch tabs. I''ve tried CListCtrl::DeleteColumn() and it does not seem to have an effect. I have also tried...

int headCount = m_ListCtrl.GetHeaderCtrl()->GetItemCount();

for(int i = 0; i < headCount; i++)
{
    m_ListCtrl.GetHeaderCtrl()->DeleteItem(i);
}

Any suggestions?

推荐答案

您的上述代码将无法删除所有列，一半将始终保留:

假设您有3列

第0、1和2列

删除第0列，现在有第0列和第1列，其余的列将得到提升.
您删除第1列，现在只有第0列
您尝试删除第2列，但调用失败，因为第2列中没有该列

Your above code would fail to delete all the columns, half would always remain:

Say you had 3 columns

Columns 0, 1 and 2

you delete column 0, you now have columns 0, 1 as the remaining columns get promoted.
you delete column 1, you now have column 0 only
you attempt to delete column 2, but the call fails as there in no column 2

for(int i = 0; i < headCount; i++)
{
    m_ListCtrl.GetHeaderCtrl()->DeleteItem(0); // always delete column 0 only
}

您需要按照 ^ ].
