Insert image in cell grid.

[dkaip]

Hello.
I am trying to input an image file in a cell of wxGrid. I can't find an example in minimal wxGrid.
So looking around find some code, but can't make work. I am putting code.
Thank's
Jim

Code: Select all

class ImageGridCellRenderer : public wxGridCellStringRenderer
{
public:
    virtual void Draw(wxGrid& grid, wxGridCellAttr& attr, wxDC& dc, const wxRect& rect, int row, int col, bool isSelected);
    wxString image;
};

void ImageGridCellRenderer::Draw(wxGrid& grid, wxGridCellAttr& attr, wxDC& dc, const wxRect& rect, int row, int col, bool isSelected)
   {
      wxGridCellStringRenderer::Draw(grid, attr, dc, rect, row, col, isSelected);

      wxImage cellImage;

      if (cellImage.LoadFile(image))
      {
         wxBitmap cellBitmap(cellImage);
         dc.DrawBitmap(cellBitmap, rect.x, rect.y);
      }
      else
      {
         wxLogError(_T("The image in cell:\n row '%d', column '%d',\n didn't load, does it exist?"), row, col);
         grid.SetCellValue(row, col,_T("Here's should be an image"));
      }
   };

bool addimage(wxString s/*image file on disk*/)
{
    m_grid1->SetCellValue(row,0,"image of file..");// col 0
    // col 1 the image..
    ImageGridCellRenderer* R =new ImageGridCellRenderer();
    wxGridCellAttr *att=m_grid1->GetCellAttr(row,1);
    R->Draw(s,m_grid1,att,wxPaintDC(this),wxRect(),row,1,1); // errors ..
    m_grid1->SetCellRenderer(row, 1, R);
}

Hi,
You probably don't want the string renderer to be a base class.

Thank you.

I don't know nothing about it. I Just learn and try to find an example for study.
Thanks for reply.

Hi,
Try to derive from this.
And use wxBitmap instead of wxString.

See how to do drawing in the drawing sample provided with wxWidgets.

Thank you.

P.S.: Also you indicated you are getting errors. Can you post them?
