Hello,
It seems there is another issue with the .Net Core SDK.
There is a need to set with of the column of a table. There is a function,
which sets the width of a table column, listed below. The function is
converted from the code, which works with the .Net Framework SDK.
void SetColumnWidth(XTextTable textTable,int ColNum, short Width)
{
Any obj =
textTable.query<XPropertySet>().getPropertyValue("TableColumnSeparators");
TableColumnSeparator[] tcs = (TableColumnSeparator[])(obj.Value);
short Delta = 0;
if (tcs != null)
{
if (tcs.Length - 1 >= ColNum)
{
if (ColNum == 0)
{
Delta = (short)(Width - tcs[ColNum].Position);
tcs[ColNum].Position = Width;
}
else
{
Delta = (short)(Width - (tcs[ColNum].Position -
tcs[ColNum].Position));
tcs[ColNum].Position = (short)(Width + tcs[ColNum -
1].Position);
}
}
Any val = new Any(typeof(com.sun.star.text.TableColumnSeparator[]),
tcs);
textTable.query<XPropertySet>().setPropertyValue("TableColumnSeparators",
val);
}
}
If the function is called in
\sdk\examples\dotnet\WriterDemo\csharp\WriterDemo.cs, like listed below:
// Get first row
XTableRows tableRows = textTable.getRows();
Any rowAny = tableRows.query<XIndexAccess>().getByIndex(0);
*SetColumnWidth(textTable, 1, 200);*
// Set a different background color for the first row
XPropertySet firstRowPropertySet = rowAny.cast<XPropertySet>();
firstRowPropertySet.setPropertyValue("BackTransparent", new Any(false));
It gives an access violation error ("Attempted to read or write protected
memory. This is often an indication that other memory is corrupt") on the
line
textTable.query<XPropertySet>().setPropertyValue("TableColumnSeparators",
val);
When I tried to get the columns of the table via the code below (the code
is inserted in the WriterDemo.cs example too):
// Set the table background color
XPropertySet tablePropertySet = textTableI.query<XPropertySet>();
tablePropertySet.setPropertyValue("BackTransparent", new Any(false));
tablePropertySet.setPropertyValue("BackColor", new Any(0xCCCCFF));
*XTableColumns tableCols = textTable.getColumns();Any colAny =
tableCols.query<XIndexAccess>().getByIndex(1);*
// Get first row
XTableRows tableRows = textTable.getRows();
Any rowAny = tableRows.query<XIndexAccess>().getByIndex(0);
However, the tableCols.query<XIndexAccess>().getByIndex(1) line give
another error:
Exception thrown: 'System.ArgumentException' in net_basetypes.dll
An unhandled exception of type 'System.ArgumentException' occurred in
net_basetypes.dll
Value of Any can only be null if Type is void. Perhaps you want Any.VOID?
Could you tell me what is a proper way to change the table column width
using the .Net Core SDK?
