TOM -- ITextDocument and ITextPara

Andre LeBlanc 21

Hello,

Can someone please shed some light on how to create paragraphs that are fixed width (e.g. a document column??)? For example, let's assume for the sake of argument, a structure like below, and the width of the document is 10,800 twips:

some text (less than 10800 twips)

A table (width of cells total 10800 twips)

some more text that takes one entire page 8.5x11 (I tried hr = pParaDuplicate->SetPageBreakBefore(tomTrue) to no avail) (how to limit width of this text to 10800 twips does it need to be put in a 1x1 table??)

Thank you!

Do you mind showing a minimal, reproducible sample without private information? Have you tried ITextPara::SetAlignment and ITextPara::SetIndents?

Hello XiaopoYang,

Apparently, a callback function is necessary for inserting page breaks:

static DWORD CALLBACK
PageBreakCallBack(DWORD dwCookie, LPBYTE lpBuffer, LONG lSize, LONG* plWrite)
{
    LONG c;
    char szString[] = "{\\rtf\\page \\par}\0";

    c = lSize;
    c = strlen(szString);
    if (*plWrite > c)
    {
        strncpy((char*)lpBuffer, szString, c + 1);
        *plWrite = c;
        return 0;
    }
    else
        return c;
}

int InsertPageBreak(HWND hWndRE, long lStart, long lEnd)
{
    EDITSTREAM es;
    CHARRANGE crSel;
    DWORD nRead;

    GETTEXTLENGTHEX gtlx = { GTL_PRECISE, CP_ACP };
    long lTextLength = SendMessage(hWndRE, EM_GETTEXTLENGTHEX, (WPARAM)&gtlx, 0);

    SendMessage(hWndRE, EM_EXGETSEL, 0, (LPARAM)&crSel);

    crSel.cpMin = lStart;
    crSel.cpMax = lEnd;
    SendMessage(hWndRE, EM_EXSETSEL, 0, (LPARAM)&crSel);

    es.dwCookie = 0;
    es.dwError = 0;
    es.pfnCallback = (EDITSTREAMCALLBACK)PageBreakCallBack;

    nRead = SendMessage(hWndRE, EM_STREAMIN, SF_RTF | SFF_SELECTION, (LPARAM)&es);
    return nRead;
}

What does the code mean? You solved the problem? Or could you please show a minimal, reproducible sample without private information using Github or something else?
