[pygtk] Removing the cursor

[Mike Bernson]

It look like I cannot do what I want.

That is remove the insert cursor from an entry widget that can get the
focus but does not allow editing. I want to be able to stop off while
tabbing thought the screen at the entry widget but attach signal handler
to grab the input character and use them for something else other then
altering the display. When I am doing this I have a message in the text
area tilling the use what to do.

I have it all working except removing the insert cursor. Since it is not
a window/X11 cursor but is draw by the entry using a helper function in
the style that I do not have access to I was looking for a way around
having the insert cursor show up.

Entry widget uses gtk_draw_insertion_cursor  inside the gtkstyle. I see
no way of accessing this function/method from python.

Here is the header from that function:
/**
 * gtk_draw_insertion_cursor:
 * @widget:  a #GtkWidget
 * @drawable: a #GdkDrawable
 * @area: rectangle to which the output is clipped, or %NULL if the
 *        output should not be clipped
 * @location: location where to draw the cursor (@location->width is
ignored)
 * @is_primary: if the cursor should be the primary cursor color.
 * @direction: whether the cursor is left-to-right or
 *             right-to-left. Should never be #GTK_TEXT_DIR_NONE
 * @draw_arrow: %TRUE to draw a directional arrow on the
 *        cursor. Should be %FALSE unless the cursor is split.
 *
 * Draws a text caret on @drawable at @location. This is not a style
function
 * but merely a convenience function for drawing the standard cursor shape.
 *
 * Since: 2.4
