Can some one help me with an ocx file of this cute code so that the same can be used in VB6 for saving and retrieving data from .mdb file.
|

First, I want to say, this code is really really excellent.
I try to update the supergrid in run-time, such as, add or delete some columns, so first i call the function of SuperGrid "DeleteAll" but it just deletes items of list, not include columns. And then i modified the code in "CMySuperGrid" function "_DeleteAll"by the codes below:
void CMySuperGrid::_DeleteAll()
{
DeleteAll(); CHeaderCtrl* pHeader=this->GetHeaderCtrl();
int i, nCount=pHeader->GetItemCount();
for(i=nCount-1; i>=0; i--)
pHeader->DeleteItem(i);
LPTSTR lpszCols[] = {_T("Tree thing"),_T("Column #1"),_T("Column #2"),_T("Column #3"),_T("Column #4"),_T("Column #5"),0};
LV_COLUMN lvColumn;
lvColumn.mask = LVCF_FMT | LVCF_WIDTH | LVCF_TEXT | LVCF_SUBITEM;
lvColumn.fmt = LVCFMT_LEFT;
lvColumn.cx = 200;
for(int x = 0; lpszCols[x]!=NULL; x++)
{
if(x)
lvColumn.cx = 150;
lvColumn.pszText = lpszCols[x];
InsertColumn(x,&lvColumn);
}
CItemInfo* lp = new CItemInfo();
lp->SetImage(4);
lp->SetItemText(_T("New data"));
CTreeItem * pRoot = InsertRootItem(lp); if( pRoot == NULL )
return;
int nCol = GetNumCol();
for(i=0; i < nCol; i++)
{
CItemInfo* lpItemInfo = new CItemInfo();
CString strItem;
strItem.Format(_T("Item %d"),i);
lpItemInfo->SetItemText(strItem);
for(int y=0;y < nCol-1; y++)
{
CString str;
str.Format(_T("subItem %d of %s"),y,lpItemInfo->GetItemText());
lpItemInfo->AddSubItemText(str);
lpItemInfo->AddSubItemText(str);
}
CTreeItem* pParent = InsertItem(pRoot, lpItemInfo);
if(i%nCol)
{
CTreeItem* pParent1=NULL;
CTreeItem* pParent2=NULL;
for(int x=0; x < nCol; x++)
{
CItemInfo* lpItemInfo = new CItemInfo();
CString strItem;
strItem.Format(_T("Item %d"),x);
lpItemInfo->SetItemText(strItem);
for(int z=0; z < nCol-1; z++)
{
CString str;
str.Format(_T("subItem %d of %s"),z, lpItemInfo->GetItemText());
lpItemInfo->AddSubItemText(str);
}
pParent1 = InsertItem(pParent, lpItemInfo);
}
}
}
Expand(pRoot, 0 );
UINT uflag = LVIS_SELECTED | LVIS_FOCUSED;
SetItemState(0, uflag, uflag);
}
but after this, readd columns and items, it shows some different, after drawing, there are columns at the end of the this new columns i created. how could i recreate the columns and items.

m_List.SetImageList (CImageList::FromHandle (GetSystemImageList (FALSE)), LVSIL_NORMAL);
HIMAGELIST CTreeListDlg::GetSystemImageList(BOOL bLarge)
{
SHFILEINFO sfi;
UINT uFlag = bLarge ? SHGFI_LARGEICON : SHGFI_SMALLICON;
return (HIMAGELIST) SHGetFileInfo (TEXT (""), NULL, &sfi, sizeof (sfi), SHGFI_SYSICONINDEX | uFlag);
}
int CShowProcessTree::GetIcon(LPTSTR szPath, UINT uFlags)
{
SHFILEINFO sfi;
SHGetFileInfo (szPath, NULL, &sfi, sizeof (sfi), SHGFI_SYSICONINDEX | uFlags);
return sfi.iIcon;
}
i saw your function SetImage(index) to get index Image from BitMap
but how to add Icon Process to...when i got icon of it?
i added successful in Tree..but when i use your control...i don't know how
can you give me a funtion to add Icon (i got from SystemIcon of that Process)

I'm looking for a way to group edit boxes with labels. I want to keep it simple. I could use a grid if I needed to, but this looks a lot cleaner.
Thanks!

before go into DrawItem(), I set the column with the item's length in LVN_GETDISPINFO process function OnGetDispInfo().
But there are some problem in DrawItem() that i can't find the reason.
[problem]
suppose i have follow data:
[+]ICON aaa
[+]ICON aaaa
[+]ICON aaaaa
DrawItem() first:
[+]ICON aaa
DrawItem() second:
[+]ICON aaa
___________a // before 'a', nothing
DrawItem() third:
[+]ICON aaa
___________a // before 'a', nothing
____________a // before 'a', nothing
have some idea? Thank you very much!

my data is dynamic load from database,and i have carried it out only in the this
control.
my problem is i used the tree to control the data display in the list
tree control.On this way,i selchanged on the my tree control need display the data
in the list tree.at first,In my tree control selchange function i used the
deleteAll() function to delete the list tree all items and display the new
data.when i use the deleteall function the program will be intermitted. when i
used the DeleteAllItems() function to delete the list tree data,itself delete the
child node and display the child node function will be error.it display the data
not right.
like this:
+Root1
+Root2
+Root3
expend the Root1 then Root2 node will be delete and collapsed the Root1 it can't
delete itself children.
someone can help me or give me some suggestion,thanks

Hi,
This is fantastic and just what I need. However, I'm using VB6 to write my app (loads of very good reasons for that which I won't go into). Do you have the control compiled as an OCX?
Cheers,

Settting the check in a root level item does not work. For example the following code addition to the demo (InitializeGrid method) fails to set the check:
CItemInfo* lp = new CItemInfo();
lp->SetCheck(1);
lp->SetImage(4);
//add item text
lp->SetItemText(_T("Hello World"));
//add subitem text
lp->AddSubItemText(_T("Happy"));
....
I'm hunting this bug down now...

To fix:
In CSuperGridCtrl::InsertRootItem(CItemInfo * lpInfo)
starting line 1488:
CItemInfo* lp = GetData(pRoot);
LV_ITEM lvItem;
lvItem.mask = LVIF_TEXT | LVIF_INDENT | LVIF_PARAM;
CString strItem = lp->GetItemText();
lvItem.pszText = strItem.GetBuffer(1);
lvItem.iItem = GetItemCount();
lvItem.lParam = (LPARAM)pRoot;
lvItem.iIndent = 1;
lvItem.iSubItem = 0;
CListCtrl::InsertItem(&lvItem);
//Add this line in to let CListCtrl know about the check
SetCheck(lvItem.iItem, lpInfo->GetCheck());
** Sometimes you know yourself something is a bad idea; follow your instinct **
//yes I know..have to maintain to sets of checkstates here...
//one for listview statemask and one for CTreeItem..but its located here so no harm done
SetCheck(ht.iItem,!GetCheck(ht.iItem));
CItemInfo *pInfo = GetData(pItem);
pInfo->SetCheck(!pInfo->GetCheck());

First,i should say thanks to your effort.i take advantage of your control in my own project. but i think the interface is too large to manipulate.
would you give me a description on how do you combine "LIST" with "TREE" ?
the tree like thing is in the first column .when a tree subitem collapses ,the relevent items in list acts accordingly . how does it work ?
|
|
|
|
|
Do you have any plans to implement nested List-Controls or Supergrids instead of 'normal' rows (like FlyGrid.Net or Sandgrid) ?
|
|
|
|
|
Really useful but is it possible to add checkboxes to the SuperGrid in the dialog?
Do the controls work also in the dialog view?
Can't get them to work.
I would really appreciate anyones help?
I'm not daft, just stupid really!!!

Dear All,
I am new in Visual C++. I use the Microsoft Visual C++ Version 6.0 and i have a small problem with the list control.
I cannot find a way (or i do not understand) how i could change the letter in specific lines with bolt and change at the same lines the text color and the background color.
Until now i am using the report style with a grid and i am load the data from a database.
I hope someone helps me as soon as possible.
Thans in advabce for your time.
Best regards,
Konstantinos.

thanks again.

the version in this page is the one updated in 14 july(by history text) .it doesnot support the subitem'image.
the newest version is 4 dec. where is it ?

Hi;
If anyone has implemented this style,can u please post it here ??

In listCtrl, we can use SetItemData to bound DWORD to every list item, but in this control, we can't do that, hope you can give those functions:SetItemData, GetItemData.;P
|
|
|
|
|
To set data use:
CItemInfo *lpItem=new CItemInfo();
int <CODE>YourValue</CODE>=123;
lpItem->SetItemText(_T("Note"));
lpItem->m_lParam=<CODE>YourValue</CODE>;
m_listItem.InsertRootItem(lpItem);
To get data (For example in OnNMDblclkGrid()):
CTreeItem* pSelItem=m_listItem.GetTreeItem(index);
int <CODE>YourValue</CODE>=(int)pSelItem->m_lpNodeInfo->m_lParam;

Hi guru,
I am a newbie in C++ Programming. I am trying to use this control on my bill of material (BOM) program. I have a list of BOM (ParentNo, ChildNo, Description, etc) that I want to display using this control. So, I use loop (for i = ...) to loop through the list and InsertItem(ParentNo, ChildNo). How do I write the loop program to insert all the ChildNo using ParentNo as the Parent. Please Note: ParwentNo is not displayed, it's only used to specified where the ChildNo belonged to. Thank you for all your help and suggestion.
Tom.

I want to be able to sort list by clicking on a column header. It should sort depending on column data type.
I am beginner in C++..
But I like control, a lot. It reminds me of Delphi control I like (ELTreeView from LMD Tools)

Hi;
I'm popping up a dialog containing only a CComboBoxEx in response to a column RClick. The last ComboboxEx list item text (as soon as DoModal on dialog) appears in all supergrid cells (in created rows) that have not been initialized with text or have been initialized with _T(""). The reason for the popup (rather than using a cell Listbox) is for UI consistency with other cells which require more complex dialogs.
The workaround to this is to initialize all column cells with _T(" ") at row creation.
If anyone wants to look into this, let me know and I will put together a simple test case.
Regards;
Bill

I have been using this control for a while and it works nicely once you understand it, but it seems there is no way to sort on the root items. Try it in the example. You'll see that the top most root items don't sort. Only the children do.
I added some code to try to fix this problem, by calling CListView::SortItems() and then swapping the corresponding CTreeItem pointers among each LV_ITEM in the view. It does sort, but the children don't show correctly when the +/- signs are clicked.
Anyone figure this one out?

I'm sorry to say - but while I'm sure you've worked a lot on it, and the UI looks great -,
IT IS EXTREMELY HARD TO USE IN REAL APPS.
In fact, it made my life a nightmare to use (I've worked on a project that used this class, and needed to customize the UI).
I would suggest you provide a MUCH simpler interface . The current one is way too big, hard to understand, and error prone.
Especially, what really killed me, was the fact that when the user clicks a "Collapse" button, my list items are DELETED. Thus, I needed to create an extra wrapper to somewhere hold references to their text.
Then, I had to create a custom mechanism for uniquely identifying an item in such a Super Grid (since the item's index wouldn't work)

Sorry for the harsh words - I was very angry at that time. You must have put a lot of effort in it.
I still think the interface is too huge, and perhaps it could benefit greatly from templates
Best,
John

[snipped a useless rant]
Nevermind! I'm stupid. and a jerk. Sorry. You must have spent a lot of time working on this and it does look great, when I can get it work. There is a little bit of overhead in getting this to work for in an application, but other than that I think it looks great.
However this question still stands. Also, what if you don't want images in the tree control?
I may fiddle with this and check. It seems whenver I eliminate the images the plus boxes also go away. Any attempt to doctor that space and the plus bozes get changed. Kinda a headache.
But good work! Thanks for sharing!
Thanks!

Not sure what I was thinking here. Yeah... would have been nice if I just posted the silly fix. Here is DrawItem. Look for the variable "m_NoImages". this variable is set by me if I have images or not. if not, I am commenting out code that deals with them. I've cut out some stuff to help with length. Hopefully it makes sense.
void CSuperGridCtrl::DrawItem(LPDRAWITEMSTRUCT lpDrawItemStruct)
{
if (lpDrawItemStruct->CtlType != ODT_LISTVIEW)
return;
if(lpDrawItemStruct->itemAction == ODA_DRAWENTIRE)
{
...
CRect rcClip = lpDrawItemStruct->rcItem;
if(m_NoImages)
rcClip.left -= 20;
rcClip.left += GetIndent(pSelItem) * m_cxImage + m_cxImage + 2;
if(rcClip.left > GetColumnWidth(0))
rcClip.left = GetColumnWidth(0);
ExtTextOut(pDC->GetSafeHdc(), 0, 0, ETO_OPAQUE, CRect(0, rcClip.top, rcClip.right, rcClip.bottom), NULL, 0, NULL);
if((nWidth=m_cxImage-nWidth) >-1) {
if(!m_NoImages)
{
ImageList_DrawEx(m_himl, lvi.iImage, pDC->m_hDC,
rc.left + (GetIndent(pSelItem) * m_cxImage),
nY,
nWidth,
m_cyImage,
CLR_DEFAULT,
CLR_DEFAULT,
uiFlags);
}
DrawTreeItem(pDC, pSelItem, nItem, rc);
}
...
GetItemRect(nItem, rcItem, LVIR_LABEL);
pszText = MakeShortString(pDC, szBuff, rcItem.right - rcItem.left, 2*OFFSET_FIRST);
rcLabel = rcItem;
pDC->SetBkColor (crBackground);
pDC->SetTextColor (crText);
rcLabel.left+=OFFSET_FIRST;
rcLabel.right-=OFFSET_FIRST;
if(m_NoImages)
rcLabel.left -= 20;
pDC->DrawText(pszText,-1, rcLabel,DT_LEFT | DT_SINGLELINE | DT_NOPREFIX | DT_VCENTER | DT_EXTERNALLEADING);
...
}}
Here a screen clip
from an application i am currently designing that shows the grid without the icons.
i have been working with this control quite a bit and have a LOT of logic changes and bug fixes. If the author would like a copy of my files I will send them. It's hard to put everything into this comment board. Also, I forgot many of the changes I put in. I don't comment as much as I should.
