[HJG] This variation of [Lotto] by [RS] writes a log of each drawing to the console, compares the drawing to the tip, and counts the matching numbers. ---- ##-##################################################################### # Lotto2.tcl - 2005-06-05 # # Todo: # * clicking on the numbers should set/reset the numbers in the tip # * use a text-widget or listview for the log # * Statistics (frequency of drawn numbers, winnings...) proc main {} { set dx 15 set dy 15 pack [canvas .c -width [expr {$dx*8}] -height [expr {$dy*8}] -bg gray77] set x $dx; set y $dy foreach i [iota1 49] { # .c create text $x $y -text $i if [lsearch $::MyTip $i]>=0 { .c create text $x $y -text $i -fill white } else { .c create text $x $y -text $i -fill black } if {$i%7} { incr x $dx } else {set x $dx; incr y $dy} } button .b -text "Draw" -command {draw .c} pack .b bind .c <1> {click .c} } proc click w { set i [$w itemcget current -text] # Check if $i exists, e.g. a valid number was clicked: if {!

So if the 49 numbers are the first items created, their identifiers are the same as their numeric values, and the number under the cursor can be retrieved by $w find withtag current (as the ''current'' tag goes temporarily to the item under the cursor). A more robust way, not depending on canvas object creation order, might be $w itemcget current -text which of course returns the displayed string of a text item (and throws an error on others). [HJG] Ok, that helps me another step forward. But now I have trouble checking the existance of a variable (proc click), e.g. when the click does not hit one of the text-widgets. -[RS]: ''i'' exists, because you just assigned it a value.. check for {$i ne ""} :) ---- [Category Toys]
