How can I create items of a Tk pop-up menu conditionally, for example with a switch 0/1 for the first command? (Possibly still using the same way to construct the -menuitems array (since I ve got increadibly many of such menus). This is how I construct my menu:
$menu = $mw->Menu(-tearoff=>0, -menuitems=>[
[command=>$MESS_0= -command=>[\&DialogMove, $obj,]],
'',
[command=>$MESS_1, -command=>[sub {MoveColumn('right')}, $obj,]],
[command=>$MESS_2, -command=>[sub {MoveColumn('left')}, $obj,]],
'',
[command=>$MESS_3, -command=>[sub {HideColumn()}, $obj,]],
[command=>$MESS_4, -command=>[sub {
if ($ContentColumn11GLOBAL eq 11){$ContentColumn11GLOBAL=0}
else {$ContentColumn11GLOBAL=11}
SetViewFromSearchFrame11($ContentColumn11GLOBAL);
}, $obj,]],
[command=>$MESS_5, -command=>[sub {
if ($ContentColumn12GLOBAL eq 12){$ContentColumn12GLOBAL=0}
else {$ContentColumn12GLOBAL=12}
SetViewFromSearchFrame12($ContentColumn12GLOBAL);
}, $obj,]],
]);
$menu->configure(-postcommand => sub {
redefine_labels();
$menu->entryconfigure(2, -label => $MESS_1);
$menu->entryconfigure(3, -label => $MESS_2);
$menu->entryconfigure(5, -label => $MESS_3);
$menu->entryconfigure(6, -label => $MESS_4);
$menu->entryconfigure(7, -label => $MESS_5);
});
