[wxPython] User-defined cursors in X?

wxPython Users
1

Are user-defined cursors now supported under
both X & Windows32 using

  wxCursor(filename,flags,hotSpotX,hotSpotY) ???

Thanks,
Bill

wxGTK doesn't have this contructor.

Is this something I should bring up with wxWindows dev?
It's kind of hard to have a uniform presentation across
platforms this way. (I want special cursors like a razor
blade when in edit mode, etc.)

Thanks,
Bill

It's certainly worth a quick note, but I bet it isn't supported in GTK
itself, and therefor not in wxGTK. IN fact, if you did a search in the
archives, it's probably been discussed.

GIMP started using different cursors for different tools, a while ago, so I
wouldn't say that it's impossoble to set the cursor when using GTK+....

Also, if you check the documentation for wxWindows' global wxSetCursor
function, it says: "Globally sets the cursor; only has an effect in Windows
and GTK."

This link shows it supported in GDK:

http://developer.gnome.org/doc/API/gdk/gdk-cursors.html

···

------------------------------------------------------
gdk_cursor_new_from_pixmap ()

GdkCursor* gdk_cursor_new_from_pixmap (GdkPixmap *source,
                                              GdkPixmap *mask,
                                              GdkColor *fg,
                                              GdkColor *bg,
                                              gint x,
                                              gint y);

Creates a new cursor from a given pixmap and mask. Both the pixmap and
mask must have a depth of 1 (i.e. each pixel has
only 2 values - on or off). The standard cursor size is 16 by 16 pixels.

Example:
  source = gdk_bitmap_create_from_data (NULL, cursor1_bits,
                                         cursor1_width, cursor1_height);
   mask = gdk_bitmap_create_from_data (NULL, cursor1mask_bits,
                                       cursor1_width, cursor1_height);
   cursor = gdk_cursor_new_from_pixmap (source, mask, &fg, &bg, 8, 8);
   gdk_pixmap_unref (source);
   gdk_pixmap_unref (mask);

   gdk_window_set_cursor (widget->window, cursor);

source : the pixmap specifying the cursor.
mask : the pixmap specifying the mask, which must be the same size as
source.
source : the pixmap specifying the cursor.
mask : the pixmap specifying the mask, which must be the same size as
source.
fg : the foreground color, used for the bits in the source which are 1.
The color does not have to be allocated first.
bg : the background color, used for the bits in the source which are 0.
The color does not have to be allocated first.
x :the horizontal offset of the 'hotspot' of the cursor.
y :the vertical offset of the 'hotspot' of the cursor.
Returns :a new GdkCursor.
