wxStaticBitmap +text Topic is solved

[TGT]

Hi,

the idea was to simple but a text onto a bitmap
I guess this is really basic stuff but it seems missing something

.h

Code: Select all

// headers

class
wxBitmapCaption : public wxStaticBitmap
{
  public:
    // the 3 constructors of wxStaticBitmap
    wxBitmapCaption();
    wxBitmapCaption( ... );
    void OnPaint(wxPaintEvent &event);

  private:
    DECLARE_EVENT_TABLE();
};

.cpp

Code: Select all

// headers

BEGIN_EVENT_TABLE(wxBitmapCaption, wxStaticBitmap)
  EVT_PAINT(wxBitmapCaption::OnPaint)
END_EVENT_TABLE()

// ... the constructors

void
wxBitmapCaption::OnPaint(wxPaintEvent &WXUNUSED(event))
{
  wxPaintDC dc(this);
  dc.DrawText(wxT("text"), 10, 10);
}

Thanks for any replies, Tom

Your are handling the EVT_PAINT, so all the drawing will need to be taken care by you. thats why you can't see the bitmap. you have to manually select the bitmap and draw yourself, then the text over it.

*arg* another time forgot the description of the behavior sorry.

I do see the picture/ bitmap but the text isn't visible.
The wxBitmapCaption is used as follows:

Code: Select all

wxImage::AddHandler(new wxPNGHandler);
wxImage img(wxT("picutre.png"), wxBITMAP_TYPE_PNG);
wxBitmapCaption *bc = new wxBitmapCaption(this, wxID_ANY, wxBitmap(&img));

// +sizer

You have to take wxMemoryDC and draw directly onto the wxBitmap object of the wxStaticBitmap!
