<![CDATA[ListView und Groups! Was mache ich nur falsch...]]>Hallo.
Windows XP unterstützt bei ListViews die Groups.

ListView_InsertGroup() etc!
Ich habe eine einfügen können, aber nach der 1. ist Schluss. Wieso nur?

LVGROUP lvg, lvg2, lvg3;

lvg.cbSize    = sizeof(LVGROUP);
lvg.mask      = LVGF_GROUPID | LVGF_ALIGN | LVGF_HEADER;
lvg.pszHeader = L"Eine Group\0";
lvg.cchHeader = wcslen(lvg.pszHeader);
lvg.iGroupId  = 0;
lvg.uAlign    = LVGA_HEADER_LEFT;
if(ListView_InsertGroup(GetDlgItem(hDlg, IDC_LIST), -1, &lvg) == -1)
	MessageBox(0, "Error 1", 0, 0);

lvg2.cbSize    = sizeof(LVGROUP);
lvg2.mask      = LVGF_GROUPID | LVGF_ALIGN | LVGF_HEADER;
lvg2.pszHeader = L"Eine Group 2\0";
lvg2.cchHeader = wcslen(lvg2.pszHeader);
lvg2.iGroupId  = 1;
lvg2.uAlign    = LVGA_HEADER_LEFT;
if(ListView_InsertGroup(GetDlgItem(hDlg, IDC_LIST), -1, &lvg2) == -1)
	MessageBox(0, "Error 2", 0, 0);

lvg3.cbSize    = sizeof(LVGROUP);
lvg3.mask      = LVGF_GROUPID | LVGF_ALIGN | LVGF_HEADER;
lvg3.pszHeader = L"Eine Group 3\0";
lvg3.cchHeader = wcslen(lvg3.pszHeader);
lvg3.iGroupId  = 2;
lvg3.uAlign    = LVGA_HEADER_LEFT;
if(ListView_InsertGroup(GetDlgItem(hDlg, IDC_LIST), -1, &lvg3) == -1)
	MessageBox(0, "Error 3", 0, 0);

hast du mal probiert bei ListView_InsertGroup(..) die richtigen indices zu geben (0, 1, 2, ...) oder mal die erste group als 0 und alle folgenden mit -1

Was mache ich nur falsch... on Tue, 06 Apr 2004 10:19:18 GMT]]>Ehm ja habe ich, es geht nicht. Es scheint nur immer der Code mit der ID 1 im Struct zu gehen.

ListView_EnableGroupView(GetDlgItem(hDlg, IDC_LIST), true);

LVGROUP lvg, lvg2, lvg3;
//ZeroMemory(&lvg, 0);
lvg.cbSize    = sizeof(LVGROUP);
lvg.mask      = LVGF_GROUPID | LVGF_ALIGN | LVGF_HEADER;
lvg.pszHeader = L"Eine Group\0";
lvg.cchHeader = wcslen(lvg.pszHeader);
lvg.iGroupId  = 0;
lvg.uAlign    = LVGA_HEADER_LEFT;
if(ListView_InsertGroup(GetDlgItem(hDlg, IDC_LIST), 0, &lvg) == -1)
	MessageBox(0, "Error 1", 0, 0);

//ZeroMemory(&lvg2, 0);
lvg2.cbSize    = sizeof(LVGROUP);
lvg2.mask      = LVGF_GROUPID | LVGF_ALIGN | LVGF_HEADER;
lvg2.pszHeader = L"Eine Group 2\0";
lvg2.cchHeader = wcslen(lvg2.pszHeader);
lvg2.iGroupId  = 1;
lvg2.uAlign    = LVGA_HEADER_LEFT;
if(ListView_InsertGroup(GetDlgItem(hDlg, IDC_LIST), 1, &lvg2) == -1)
	MessageBox(0, "Error 2", 0, 0);

lvg3.cbSize    = sizeof(LVGROUP);
lvg3.mask      = LVGF_GROUPID | LVGF_ALIGN | LVGF_HEADER;
lvg3.pszHeader = L"Eine Group 3\0";
lvg3.cchHeader = wcslen(lvg3.pszHeader);
lvg3.iGroupId  = 2;
lvg3.uAlign    = LVGA_HEADER_LEFT;
if(ListView_InsertGroup(GetDlgItem(hDlg, IDC_LIST), 2, &lvg3) == -1)
	MessageBox(0, "Error 3", 0, 0);

Aber da kommt kein Error aber nur eine Group (die erste)!

LVGROUP lvg; 
//ZeroMemory(&lvg, 0); 
lvg.cbSize    = sizeof(LVGROUP); 
lvg.mask      = LVGF_GROUPID | LVGF_ALIGN | LVGF_HEADER; 
lvg.pszHeader = L"Eine Group\0"; 
lvg.cchHeader = wcslen(lvg.pszHeader); 
lvg.iGroupId  = 0; 
lvg.uAlign    = LVGA_HEADER_LEFT; 

if(ListView_InsertGroup(GetDlgItem(hDlg, IDC_LIST), 0, &lvg) == -1) 
    MessageBox(0, "Error 1", 0, 0); 

lvg.pszHeader = L"Eine Group 2\0"; 
lvg.cchHeader = wcslen(lvg2.pszHeader); 
lvg.iGroupId  = 1; 

if(ListView_InsertGroup(GetDlgItem(hDlg, IDC_LIST), 1, &lvg) == -1) 
    MessageBox(0, "Error 2", 0, 0); 

lvg.pszHeader = L"Eine Group 3\0";

lvg.iGroupId  = 2;

aber leider das selbe ergebnis. es erscheint ein group: "Eine Group" also die erste HILFE
