The JLIstControl is used to create and manipulate Offline screen list controls. It constructs a new list control using the caption, row number and position information. The syntax is as follows:
JListControl(strCaption,iRowNum,iRow,iLeft,iBottom,iRight);
An example of a new JListControl is shown below:
objListControl = new JListControl(strCaption,iRowNum,iRow,iLeft,iBottom,iRight);
The JListControl is associated with the following methods.
SetColumnAttributes
This method sets the attributes for the list control's columns, including title, field names, length, type, width, and state. The syntax is as follows:
JListControl.SetColumnAttributes(strTitle,strFieldName,iLength,iType,iWidth,iState);
An example is as follows:
objListControl.SetColumnAttributes(strTitle,strFieldName,iLength,iType,iWidth,iState);
SetCellData
This method sets the values for the table cells. Values set are the row, column and actual value contained in the cell. The syntax is as follows:
JListControl.SetCellData(row,col,strValue);
An example is as follows:
objListCon
GetCellData
This method is used to get the data values from a given cell in a list control. There are two possible syntaxes - using the row and column values or using the row and field name. These are both shown below:
JListControl.GetCellData(iRow,iCol);
JListControl.GetCellData(iRow,strFieldName);
Examples are as follows:
strValue = objListControl.GetCellData(1,2);
strValue = objListControl.GetCellData(1,"field_name");
GetColNumber
This method returns the number of columns in a given table control. The syntax is as follows:
JListControl.GetColNumber( );
trol.SetCellData(1,2,"value");
SetRowRange
This method defines how many rows of a given table should display on a screen. The syntax is as follows:
JListControl.GetColFieldName(iStartRow,iEndRow);
An example is below:
objListControl.SetRowRange(1,10);
GetSelectedRow
This method returns the selected row in a list control. The syntax is as follows:
JTableControl.IsRowSelected( );
An example is shown below:
bSelected = objTableControl.IsRowSelected();
RemoveControl
This method removes a given list control from a screen. The syntax is as follows:
JListControl.RemoveControl( );
An example is shown below:
objListControl.RemoveControl( );
