Grid column border colour Topic is solved

[Peterj]

Is there any way to change the border colour of a column in a wxGrid?

Currently if a column in the grid is selected, the background colour of the column is changed, however I would rather change the border colour of the column so that I can use the background colour to indicate other properties of cell contents.

Any ideas on how this can be achieved?

Hi,
currently wxGrid uses one colour for all grids (borders), but you can create custom class derived from wxGrid and redefine virtual method

Code: Select all

    virtual wxPen GetColGridLinePen(int col);

Thanks for your reply. Can you give me an example please?

Ok,

Code: Select all

class MyGrid : public wxGrid
{
public:
        MyGrid(wxWindow* parent, wxWindowID id, const wxPoint& pos = wxDefaultPosition, const wxSize& size = wxDefaultSize, long style = wxWANTS_CHARS, const wxString& name = wxPanelNameStr)
      : wxGrid(parent, id, pos, size, style, name), m_sel_pen(*wxBLACK_PEN) {}

      void SetColSelPen(const wxPen& pen) { m_sel_pen = pen; }
      wxPen GetColSelPen() const { return m_sel_pen; }

      wxPen GetColGridLinePen(int col)
      {
          wxArrayInt sels = GetSelectedCols();
          if( sels.Index(col) != wxNOT_FOUND )   // Selected col
              return m_sel_pen;
          else                                                   // Not selected, default pen
              return GetDefaultGridLinePen();
      }

private:
      wxPen m_sel_pen;
};

.......

MyGrid* grid = new MyGrid(this, wxID_ANY);
grid->SetColSelPen(wxPen(wxColour(255, 0, 0), 2));  // For example :)

Thanks for your response.

Examples like that sure make learning easier.
