CodeProject: Full Arabic User Interface GridCtrl. Free source code and programming help

Introduction

I tried to use many grids of different types in Arabic mode but I failed, until I found GridCtrl with source. And then I worked to adapt it to work with Arabic mode in different types of Views or Dialogs.

Working with views:

void CSomeClassToWorkAsView::OnInitialUpdate() { CView::OnInitialUpdate(); // TODO: Add your specialized code here and/or call the base class if (!m_InitOn) { // Create the Gridctrl window m_pGridCtrl = new CGridCtrl; if (!m_pGridCtrl) return; m_pGridCtrl->bCreateOnView = true; CRect rect; GetClientRect(rect); m_pGridCtrl->Create(rect, this, 1001); m_InitOn = true; } if (m_InitOn) { ReGetData(); } }

Working with cells' merge:

for (col = 0; col < m_Grid.GetColumnCount(); col++) { m_Grid.SetItemBkColour(iRowCur, col, RGB(165, 27, 30)); m_Grid.SetItemFgColour(iRowCur, col, RGB(255, 255, 0)); } m_Grid.SetSelectedRange(iRowCur, ID_QUTNAME, iRowCur, ID_SELX); m_Grid.MergeSelectedCells();

Initialize normal control:

#define ID_COL_COUNT 0 #define ID_COL_DOCNO 1 #define ID_COL_DAYCOUNT 2 #define ID_COL_TDATESTART 3 #define ID_COL_TDATEEND 4 #define ID_COL_UAMTCHARGE 5 #define ID_COL_UAMTMOVE 6 #define ID_COL_UAMTENTRY 7 #define ID_COL_UAMTOTHER 8 #define ID_COL_UAMTTOTAL 9 #define ID_COL_COSTCNTR 10 #define ID_COL_MEMO 11 m_Grid.DeleteAllItems(); UpdateWindow(); m_Grid.GetDefaultCell(FALSE, FALSE)->SetBackClr(RGB(0xFF, 0xFF, 0xE0)); m_Grid.SetFixedColumnSelection(false); m_Grid.SetFixedRowSelection(false); m_Grid.SetHeaderSort(TRUE); m_Grid.EnableColumnHide(); m_Grid.SetColumnCount(12); m_Grid.SetRowCount(1); m_Grid.SetAutoSizeStyle(); m_Grid.SetCompareFunction(CGridCtrl::pfnCellNumericCompare); m_Grid.SetFixedRowCount(1); m_Grid.SetFixedColumnCount(1); GV_ITEM Item; Item.mask = GVIF_TEXT|GVIF_PARAM|GVIF_FORMAT; Item.nFormat = DT_LEFT|DT_VCENTER|DT_SINGLELINE|DT_END_ELLIPSIS; Item.nState = 0; Item.row = 0; Item.col = ID_COL_COUNT; Item.strText = "�"; m_Grid.SetItem(&Item); Item.row = 0; Item.col = ID_COL_DOCNO; Item.strText = "�� "; m_Grid.SetItem(&Item); Item.row = 0; Item.col = ID_COL_DAYCOUNT; Item.strText = "�� "; m_Grid.SetItem(&Item); Item.row = 0; Item.col = ID_COL_TDATESTART; Item.strText = "�� "; m_Grid.SetItem(&Item); Item.row = 0; Item.col = ID_COL_TDATEEND; Item.strText = "�� "; m_Grid.SetItem(&Item); Item.row = 0; Item.col = ID_COL_UAMTCHARGE; Item.strText = "�� "; m_Grid.SetItem(&Item); Item.row = 0; Item.col = ID_COL_UAMTMOVE; Item.strText = "�. ��"; m_Grid.SetItem(&Item); Item.row = 0; Item.col = ID_COL_UAMTENTRY; Item.strText = "�. ��"; m_Grid.SetItem(&Item); Item.row = 0; Item.col = ID_COL_UAMTOTHER; Item.strText = "��"; m_Grid.SetItem(&Item); Item.row = 0; Item.col = ID_COL_UAMTTOTAL; Item.strText = "��"; m_Grid.SetItem(&Item); Item.row = 0; Item.col = ID_COL_COSTCNTR; Item.strText = "�� "; m_Grid.SetItem(&Item); Item.row = 0; Item.col = ID_COL_MEMO; Item.strText = _T("�� "); m_Grid.SetItem(&Item); m_Grid.AutoSize(); m_Grid.ExpandLastColumn(); m_Grid.SetEditable(true); m_Grid.SetRowResize(false); void CSomeClassToWork::SetRowColItem(int row) { for (int col = 0; col < m_Grid.GetColumnCount(); col++) { CString str; GV_ITEM Item; Item.mask = GVIF_TEXT|GVIF_PARAM|GVIF_FORMAT; Item.nFormat = DT_LEFT|DT_VCENTER|DT_SINGLELINE|DT_END_ELLIPSIS; Item.nState = 0; Item.row = row; Item.col = col; if ( col == ID_COL_COUNT ) { CString sTemp; sTemp.Format("%d", row); Item.strText = sTemp; } if ( col == ID_COL_DOCNO ) Item.strText = _T(""); if ( col == ID_COL_DAYCOUNT ) Item.strText = _T("00"); if ( ( col >= ID_COL_COSTCNTR ) && ( col <= ID_COL_MEMO ) ) Item.strText = _T(""); if ( ( col >= ID_COL_UAMTCHARGE ) && ( col <= ID_COL_UAMTTOTAL ) ) Item.strText = _T("0.00"); if ( ( col >= ID_COL_TDATESTART ) && ( col <= ID_COL_TDATEEND ) ) Item.strText = _T(" - - "); m_Grid.SetItem(&Item); m_Grid.SetItemState(row, col, m_Grid.GetItemState(row, col) & ~GVIS_READONLY); if ( col == ID_COL_DOCNO ) { m_Grid.SetItemState(row, col, m_Grid.GetItemState(row, col) & ~GVIS_READONLY); if (!m_Grid.SetCellType(row, col, RUNTIME_CLASS(CGridCellNormal))) return; } if ( ( col >= ID_COL_COSTCNTR ) && ( col <= ID_COL_MEMO ) ) { m_Grid.SetItemState(row, col, m_Grid.GetItemState(row, col) & ~GVIS_READONLY); if (!m_Grid.SetCellType(row, col, RUNTIME_CLASS(CGridCellNormal))) return; } if ( ( col >= ID_COL_TDATESTART ) && ( col <= ID_COL_TDATEEND ) ) { if (!m_Grid.SetCellType(row, col, RUNTIME_CLASS(CGridCellDateTime))) return; CGridCellDateTime *pCell = (CGridCellDateTime*) m_Grid.GetCell(row, col); COleDateTime m_cTime; m_cTime = COleDateTime::GetCurrentTime(); pCell->m_cTime = m_cTime; CString sTDate; sTDate = m_cTime.Format("%Y-%m-%d"); m_Grid.SetItemText(row, col, sTDate); } } m_Grid.SetItemText(row, ID_COL_DOCNO , sDocNo ); m_Grid.SetItemText(row, ID_COL_DAYCOUNT , sDayCount ); m_Grid.SetItemText(row, ID_COL_TDATESTART , sTDateStart ); m_Grid.SetItemText(row, ID_COL_TDATEEND , sTDateEnd ); m_Grid.SetItemText(row, ID_COL_UAMTCHARGE , suAmtTCharge ); m_Grid.SetItemText(row, ID_COL_UAMTMOVE , suAmtTMove ); m_Grid.SetItemText(row, ID_COL_UAMTENTRY , suAmtTEntry ); m_Grid.SetItemText(row, ID_COL_UAMTOTHER , suAmtTOther ); m_Grid.SetItemText(row, ID_COL_UAMTTOTAL , suAmtTTotal ); m_Grid.SetItemText(row, ID_COL_COSTCNTR , sCostCnt ); m_Grid.SetItemText(row, ID_COL_MEMO , sHMemo ); }

Dear Tarek, Thanks a lot for your very interesting changes. But I have a problem with your code. When I use the Print command, the printed table will be very very small and also the table is reversed!!!! How can I solve it. Thanks to you. Best regards, Bahman Tahayori Thanks

First On Dialog Set the Language Properties to Neutral (Sys. Default) Second On your Project Settings -> Resources Set Language To Arabic (Saudi Arabia) this will work for arabic

Can you please post VC++ example using this control. It is not clear how to use it in virtual mode and how to place this control into dialog or FormView. Thank you.

I made a very simple VC++ sample to use that, if u need it send to me.

all what u need is to write a piece of code similar to the following in ur dialog OnInitDialog():

m_cGrid.bCreateOnView = TRUE;
m_cGrid.Create(rect,this,1001);
m_cGrid.SetEditable(true);
m_cGrid.SetListMode(false);
m_cGrid.EnableDragAndDrop(TRUE);

// Construct the columns and rows
int nRows = 4;
int nCols = 3;
m_cGrid.SetRowCount(nRows+1);
m_cGrid.SetColumnCount(nCols+1);

m_cGrid.SetFixedRowCount(1);
m_cGrid.SetFixedColumnCount(1);

m_cGrid.SetColumnResize(FALSE);
m_cGrid.SetRowResize(FALSE);

int nArrIdx = 0;
for (int nCol = 1 ;nCol <= nCols ;nCol++)
{
GV_ITEM Item;
Item.mask = GVIF_TEXT|GVIF_FORMAT;
Item.row = 0;
Item.col = nCol;
Item.nFormat = DT_WORDBREAK;

CString str;
str.Format("Column %d",nCol);
Item.strText = str;

m_cGrid.SetItem(&Item);
}

for (int nRow = 1 ;nRow <= nRows ;nRow++)
{
GV_ITEM Item;
Item.mask = GVIF_TEXT|GVIF_FORMAT;
Item.row = nRow;
Item.col = 0;
Item.nFormat = DT_WORDBREAK;

CString str;
str.Format("Row %d",nRow);
Item.strText = str;
m_cGrid.SetItem(&Item);
}

can you explain me where you declare the m_cGrid and how and the number 1001 is it the id of the gridctrl `m_cGrid.Create(rect,this,1001);`

Some suggestions

1. Consider adding a picture so the reader knows what you are talking about.
2. Some more explanations / text, rather than just code.
3. Add a credits section to the owner of the code (I understand from the introduction that you are adapting the code to work with Arabic, rather than did the code from scratch).

Regards,
Victor.
