有人用过MfcGridCtrl吗，若想在一个cell里面，不同的字符用不同的颜色，有什么方法？

MfcGridCtrl据说是最好的grid

ayasakura · 发表于 2020-6-14 13:45:01

要实现你的要求必须修改gridctrl里面的设置文字函数
必须另外加一个参数用来将你要的字体颜色传递过去估计修改起来会比较麻烦
你必须对gridctrl类很熟悉

ayasakura · 发表于 2020-8-4 14:45:02

我觉得的确修改起来比较麻烦
本身GridCtrl类就很烦琐要实现你说的功能不是一句两句能说清的
所以大家都不好回答吧
我想还不如自己写个CWnd 画网格每个Cell里填充CRichEdit
你可以上codeproject下载这个MultilineListControl看看

zgw716 · 发表于 2020-8-5 14:45:01

楼上说的对，但是每个cell里填充RichEdit会不会很占用资源阿。
我去看看你说的MultilineListControl

楼上说的对.

你为什么不在listctrl的基础重绘呢?
那样资源又低.

BOOL CGridCellBase::Draw(CDC* pDC, int nRow, int nCol, CRect rect, BOOL bEraseBkgnd /*=TRUE*/)
{
.....
//pDC->SetTextColor();修改字符的颜色,在这加你的代码
DrawText(pDC->m_hDC, GetText(), -1, rect, GetFormat() | DT_NOPREFIX);//文本输出

pDC->RestoreDC(nSavedDC);

return TRUE;
}

楼上看来是用过MFCGridCtrl这个控件，但是你那个方法只是修改了整个Cell的字体颜色。
我想在一个cell（多行显示）里不同的字符（比如搜索到的字符用红色）想用不同的颜色。

我Spy了一下别人写的程序（实现了我说的功能），高人们能从中看到别人是怎么做的吗？

他是用WM_CTLCOLORBTN进行消息反射修改控件的背景色
这在MFCGridCtrl中不能达到你的要求
你自己试一下我说的方法
将这段代码替代
CString strText = GetText();
CString strTemp = strText.Left(1);
if ( strTemp == "1" )
{
CSize szText = pDC->GetTextExtent( strTemp );
for ( int x = 0; x < strText.GetLength(); x++ )
{
strTemp = strText.Mid(x, 1);
rect.left += szText.cx*x;
if ( x % 2 )
{
pDC->SetTextColor( 0x00ff0000);
} else
{
pDC->SetTextColor( 0x0000ff00);
}

DrawText(pDC->m_hDC, strTemp, -1, rect, GetFormat() | DT_NOPREFIX);
}
} else DrawText(pDC->m_hDC, GetText(), -1, rect, GetFormat() | DT_NOPREFIX);

原来的
DrawText(pDC->m_hDC, GetText(), -1, rect, GetFormat() | DT_NOPREFIX);

看看demo中是否字符是变色显示的？
