32bit cursors Topic is solved

[Vexator]

ok now that i could manage to use 32bit bitmaps on toolbars, i'd like to do the same for cursors. i use png files with alpha channels for transparency, load them into wxImages and convert these to wxbitmaps.
i want to do the same for cursors. you can create a cursor directly from a wximage, but the docs say:

wxCursor(const wxImage& image)
Constructs a cursor from a wxImage. The cursor is monochrome, colors with the RGB elements all greater than 127 will be foreground, colors less than this background. The mask (if any) will be used as transparent.

uh?! so how can i create 32bit cursors with wx (at least on winxp) to be able to create cursors with soft transitions and shadows?

thanks in advance!

Works for me on XP. The docs are wrong.

yes, i got a 32bit png file working as a cursor but the alpha mask is not being used, so the cursor is just displayed as a square.

Maybe it has something to do with the way you load the wxImage from the file? (making sure the alpha channel is used?)

I dont know
but in windows cursors is not alpha, but some grey color (see visual c icon editor, BB icon editor)

it's the same code and file i use for my toolbar icons, and there it works..

Adding this to the minimal sample:

Code: Select all

#include <wx/image.h>

    wxImage::AddHandler(new wxPNGHandler);
    wxImage im(_T("cursor7oa.png"));
    wxCursor c(im);
    SetCursor(c);

using this png:

works fine for me.

i found the problem.. the cursors have to be 32x32, at least on win32. mine was 16x16.. thanks!
