Hi there... I'm coding this Arimma (an amazing and amusing board game) client,
and I'm using drag and drop in a table of Gtk::Image widgets to implement the
movement of the stones.
To make the user actually feels as he/she/it has grabbed the stone with the
mouse click, I have to move the drag icon to position the stone image right at
the place where the user clicked in the board image...
I had implemented it with Pixmap, using the Dragcontext method
void set_icon (const Glib::RefPtr<Gdk::Colormap>& colormap, const Glib::RefPtr<Gdk::Pixmap>& pixmap, const Glib::RefPtr<Gdk::Bitmap>& mask, int hot_x, int hot_y)
and it worked just fine. Now I decided to use a pixbuf instead of a pixmap, and when I tried to use the method
void set_icon (const Glib::RefPtr<Gdk::Pixbuf>& pixbuf, int hot_x, int hot_y)
I didn't get any error messages, but the icon was not translated... What is wrong??
The following code has the two versions, the pixmap version is commented out, and is the one that actually works... Can it be a bug in the set_icon method?
void House::on_drag_begin(const Glib::RefPtr<Gdk::DragContext>& context) {
// Glib::RefPtr<Gdk::Pixmap> stone;
// Glib::RefPtr<Gdk::Bitmap> mask;
Glib::RefPtr<Gdk::Pixbuf> stonebuf;
stonebuf = img.get_pixbuf();
// stonebuf->render_pixmap_and_mask(stone, mask, 100);
int x;
int y;
img.get_pointer(x, y);
//context->set_icon(get_colormap(), stone, mask, x, y);
context->set_icon(stonebuf, x, y);
img.set(board->board_images[lin*8+col]);
}
