How would one script things to dynamically provide the user with the range of cursors available on their platform? [aka a tk_chooseCursors that works dynamically for the platform, and includes hopefully application/user defined cursors]
How would one go about defining a new cursor via Tk scripting?
SO Oct 12, 2001 - A minimalist tk script that displays the 77 cross-platform cursors in a listbox, and configures the label above the listbox to use the currently selected cursor:
set cursors {arrow based_arrow_down based_arrow_up boat bogosity\
bottom_left_corner bottom_right_corner bottom_side bottom_tee\
box_spiral center_ptr circle clock coffee_mug cross cross_reverse\
crosshair diamond_cross dot dotbox double_arrow draft_large\
draft_small draped_box exchange fleur gobbler gumby hand1\
hand2 heart icon iron_cross left_ptr left_side left_tee leftbutton\
ll_angle lr_angle man middlebutton mouse pencil pirate plus\
question_arrow right_ptr right_side right_tee rightbutton rtl_logo\
sailboat sb_down_arrow sb_h_double_arrow sb_left_arrow\
sb_right_arrow sb_up_arrow sb_v_double_arrow shuttle sizing\
spider spraycan star target tcross top_left_arrow top_left_corner\
top_right_corner top_side top_tee trek ul_angle umbrella ur_angle\
