You need to send a wxGridTableMessage to the wxGrid to notify it that changes have been made. Search for wxGridStringTable::InsertRows(...) and see the code where it creates a new wxGridTableMessage to send to the wxGrid. You need to duplicate this. http://svn.wxwidgets.org/viewvc/wx/wxWidgets/branches/WX_2_8_BRANCH/src/generic/grid.cpp?view=markup See also "class WXDLLIMPEXP_ADV wxGridTableMessage" here. There isn't much documentation for this, but you can figure it out from the wxGridStringTable::Insert/Append/Delete/Rows/Cols() functions above. http://svn.wxwidgets.org/viewvc/wx/wxWidgets/branches/WX_2_8_BRANCH/include/wx/generic/grid.h?view=markup In the past I have written a function called UpdateGrid() (don't know where it is anymore) that gets the current number of rows/cols from the wxGrid and the number of rows/cols from my wxGridTable and sends the wxGridTableMessages as appropriate. Once you have this function you can adjust your wxGridTable as you like and then call the UpdateGrid() function to sync the wxGrid to the table. I recommend this method as opposed to duplicating the separate Insert/AppendDelete/Rows/Cols functions. > I have a report now too: seems wxGrid doesn't check the row and the column > in SetCellValue(), because when I used that with negative rows, it throw me > an unhandled exception window (well, now I have more unhandled exception > related to wxGrid, but I haven't found out, what caused that till now...). > The first problem has been 'patched' now: I know how many columns I want to > add, so I check it: > if grid:GetNumberRows() < iRows then > grid:AppendRows(grid:GetNumberRows()-1,iRows-grid:GetNumberRows()) end > But I think there must be a more elegant solution :) Unfortunately not, there are checks in the wxWidgets C++ code that will assert rather than cause an exception in the debug compiled version of wxWidgets. Perhaps I should release a binary build of wxLua compiled with the debug settings? I would rather not have to add checks for proper values to the inputs of the wxWidgets functions since there will be need to be thousands of them and that would really bloat wxLua. > --- > > Another problem that I have to print with my application.

Printing in wxWidgets is done by using a wxPrinterDC that is created by the printing framework itself. I assume you've looked at the printing.wx.lua sample. You need to replace the function DisplayFigure() with your own drawing code. You will need to use wxC::DrawText(), wxDC::GetTextExtent() and friends along with all the PPI and page size info used in the function printOut:OnPrintPage() in printing.wx.lua. You may also want to look into wxHTMLEasyPrinting, which will be able do the layout for you, but I have never used it very seriously.
