在这种情况下我无法设置宽度（使用AddDataToDisplayBox中的Format（））。请帮忙。

I am a novice in application development.
I have created a app which is expected to display following data in RichEditControl2 in tabular format, but i am facing issue with character spacing.

I am unable to set width in this case (using Format() in AddDataToDisplayBox). Please help.

void Csdlc_verifierDlg::AddDataToDisplayBox(int index,COLORREF color, bool bold, bool italic, bool underline)
{
	CString strTemp;
	char buf[255]={0};
	record_data record = mRecData.GetAt(index);	
	strTemp.Format("%-15s%-50s%-50s%-5s%-15s",record.date,record.milestone,record.tasktype,record.effort,record.name);	
	AddLine(strTemp,NEWLINE,color,bold,italic,underline);
}

int Csdlc_verifierDlg::AddLine(CString str, int seperator, COLORREF color, bool bold, bool italic, bool underline)
{			
	int txtLen = mRichEditCtrl.GetTextLength();

	// Save number of lines before insertion of new text
	int nOldLines = mRichEditCtrl.GetLineCount();

	// Initialize character format structure
	CHARFORMAT cf = {0};
	cf.cbSize = sizeof(CHARFORMAT);
	cf.dwMask = CFM_COLOR|CFM_BOLD|CFM_ITALIC|CFM_UNDERLINE|CFM_CHARSET|CFM_SPACING; //Mask validates the active field in this case.
	cf.dwEffects = (bold ? CFE_BOLD : 0) | (italic ? CFE_ITALIC : 0) | (underline ? CFE_UNDERLINE : 0);
	cf.crTextColor = color;
		
	//Add newline character, if required.
	switch(seperator)
	{
	case NEWLINE:
		str.AppendChar('\n');
		break;

	case SPACE:
		str.AppendChar(' ');
		break;
	}
	//Insert data at the end.
	mRichEditCtrl.SetSel(txtLen, -1); // Set the cursor to the end of the text area and deselect everything.
    mRichEditCtrl.ReplaceSel(str); // Inserts when nothing is selected.

    // Apply formating to the just inserted text.
	mRichEditCtrl.SetSel(txtLen-(nOldLines-1), mRichEditCtrl.GetTextLength());
    mRichEditCtrl.SetSelectionCharFormat(cf);
	
	// Scroll by the number of lines just inserted
	mRichEditCtrl.LineScroll(mRichEditCtrl.GetLineCount() - nOldLines);	
	return 0;
}

推荐答案

您需要使用标签。



格式化行时，在想要标签的位置插入\t，例如

you need to use Tabs.

When formatting the line, insert "\t" in the positions you want tabs, e.g.

strTemp.Format("%-15s\t%-50s%-50s%-5s\t%-15s",record.date,record.milestone,record.tasktype,record.effort,record.name);

然后您需要将段落格式应用于所选区域。你需要玩标签位置。下面是每行2个标签的示例，其格式适用于整个文本：

Then you need to apply the "paragraph" formatting to the selected area. You need to play with the "tab" positions. Here is example for 2 tabs per line with the format applied for the whole text:

PARAFORMAT pf;
setmem(&pf, 0, sizeof(pf)); // Clear the memory
pf.cbSize = sizeof(pf);
pf.dwMask = PFM_TABSTOPS;
pf.cTabCount = 2; // two tab stops
pf.rgxTabs[0] = 720; // In 10ths of a point
pf.rgxTabs[1] = 1440; // In 10ths of a point
mRichEditCtrl.SetSel(0, -1); // Select all the text
mRichEditCtrl.SetParaFormat(pf);

安德鲁，

''\ t''在我的情况下没有直接正常工作，因为文本长度因列值而异。因此，它需要一个计算标签数量的额外逻辑。

但是，谢谢你的支持。

Hi Andrew,
''\t'' did not work fine directly in my case, as the text length varied in case of column values. So, it needed an additional logic of calculating the number of tabs.
But thank you for your support.
