menu_bar attributes

The array item is a list, where for each item the label is menu item label and the item value is an array of attributes to query for that menu item.

w = $WIDGET("double_window", 20, 50, 340, 220, "test", {color: "BLUE"});
w.show();
w +=  (tx:$WIDGET("text_display", 20, 50, 300, 150));
w.child("tx").set({text:"blank"});

w += (menu: $WIDGET("menu_bar", 0, 0, 640, 30));
m1_cb = op(o,cbdata,item) {o.parent().child("tx").set({text:"M1"});};
w.child("menu") += (M1: {path: "&File/&M1", flags: ["DIVIDER"], shortcut: "^a", callback: m1_cb});
m2_cb = op(o,cbdata,item) {o.parent().child("tx").set({text:"M2"});};
w.child("menu") += (M2: {path: "&File/&M2", shortcut: "^b", callback: m2_cb});

w.child("menu").get([ {"M1":["path","shortcut"]} ]);
w.child("menu").set({child:{M1: {label: "M1X", "labelsize":18}}});

on_post handlers

Enables sending scripts (raw text script, not an $OP) to a widget to be compiled and run in a thread specific to that widget (async to other threads).

The script below will setup on_post handlers in the text_display widget, and then will exec a function in that widget to "post" a text script to be compiled and run in a thread.

w = $WIDGET("double_window", 0, 0, 340, 260, "test", {color: "BLUE"});
w.show();
w += (ns:$WIDGET("button", 20, 20, 40, 20, "clear", {on_release: op(o){o.next().set({"text":""});} }));
w += (tx:$WIDGET("text_display", 20, 40, 300, 200));
w.child("tx").set({  
    on_post_start: op(o)
    {
        o.set({text:""});
        o.append("on_post_start\n");
    },
    on_post_echo: op(o,data)
    {
        o.append("on_post_echo:"+data.str()+"\n");
    },
    on_post_end: op(o,data)
    {
        o.append("on_post_end:"+data.str()+"\n");
    }
   });

w.child("tx").set({exec:op(){"(1).echo();2;".post();}});

The result of the sccript below will create a window with a button and a text_display, with the text_display set to:

on_post_start
on_post_echo:1
on_post_end:2
