How to compile PNG into exec to use it in wxIcon as XPM?

[kornerr]

I.e. I can

Code: Select all

include "some.xpm"

and then wxIcon (some_xpm);
How to do the same thing with PNG? Or other format?

Thanks.

You should find enough information at:
http://wiki.wxwidgets.org/wiki.pl?Embedding_PNG_Images

I've run bin2c, but I still can't use this "c image" in wxBitmapButton:

Code: Select all

 wxBitmapButton *btn = new wxBitmapButton (this, -1, wxImage (c_image));

Also, this

Code: Select all

wxImage::AddHandler (wxPNGHandler);

doesn't work. GCC says there's parse error before ");"
I tried wxInitAllImageHandlers ();, but button has no image.

Thanks.

PS: test.tar.bz2.doc
(remove ".doc" from filename)

You should read the stuff in the wiki under "Including". You'll need a wxMemoryStream to "load" the PNG. What you do is assign the data directly, but this only works for XPM, not PNG.

So there's no way to embed PNG into my executable like XPM

 wxBitmapButton *btn = new wxBitmapButton (this, -1, wxImage (c_image));

You should do something like:

Code: Select all

wxMemoryInputStream istream(c_image, sizeof c_image);
wxImage myimage(istream, wxBITMAP_TYPE_PNG);
 wxBitmapButton *btn = new wxBitmapButton (this, -1, myimage);

Also, this

Code: Select all

wxImage::AddHandler (wxPNGHandler);

doesn't work. GCC says there's parse error before ");"

Please note the "new" keyword:

Code: Select all

wxImage::AddHandler(new wxPNGHandler);

I've done:

Code: Select all

wxMemoryInputStream input_stream (button_close_small_png, sizeof (button_close_small_png));
wxImage btn_img (input_stream, wxBITMAP_TYPE_PNG);
wxBitmapButton *btn = new wxBitmapButton (this, -1, wxBitmap (btn_img));

But when I run app, I see the warning:

Code: Select all

No image handler for type 15 defined.

and there's no image at the button.

Thanks.

how about xrc, compile the xrc file into a cpp file and wxrc will compile the dependent png images as well.

[kornerr]

And how to create xrc? How to compile it?

Thanks.

Maybe your wxWidgets library has no PNG support compiled in?
