了解POE-Tk中的名称空间-UnderstandingnamespacesinPOE-Tk

I posted "How to undersand the POE-Tk use of destroy?" in an attempt to reduce the bug in my production code to a test case. But it seems that the solution to the test case is not working in the full program.

我发布了“如何低估POE-Tk使用destroy?”试图将我的生产代码中的错误减少到测试用例。但似乎测试用例的解决方案并不适用于整个程序。

The program is 800+ lines long so I am hesitant to post it in full. I realize that the snippets I provide here may be too short to be of any use, but I hope to get some direction in either where to look for a solution or what additional information I can provide.

该计划长达800多行,所以我犹豫是否完整发布。我意识到我在这里提供的片段可能太短而无法使用,但我希望在寻找解决方案的地方或我可以提供的其他信息方面找到一些方向。

Here is the Session::Create section of my POE-Tk app.

这是我的POE-Tk应用程序的Session :: Create部分。

POE::Session->create(
    inline_states => {
        _start      => \&ui_start,
        get_zOne=> \&get_zone,
        ping        => \&ping,
        mk_disable  => \&mk_disable,
        mk_active   => \&mk_active,
        pop_up_add => \&pop_up_add,
        add_button_press => sub {
            my ($kernel, $session, $heap) = @_[KERNEL, SESSION, HEAP];
            print "\nadd button pressed\n\n";
            &validate;
        },
        ih_button_1_press => sub {
            my ($kernel, $session, $heap) = @_[KERNEL, SESSION, HEAP];
            print "\nih_button_1 pressed\n\n";
            if( Tk::Exists($heap->{ih_mw}) ) {
                print "\n\nih_mw exists in ih_button_1_press\n\n";
            } else {
                print "\n\nih_mw does not exist in ih_button_1_press\n\n";
            }
            1;
            $heap->{ih_mw}->destroy if Tk::Exists($heap->{ih_mw});
            &auth;
        },
        pop_up_del => \&pop_up_del,
        auth        => \&auth,
#       validate    => \&validate,
        auth_routine => \&auth_routine,
        raise_widget    => \&raise_widget,
        del_action  => \&del_action,
        over        => sub { exit; }
    }
);

add_button_press is called here;

这里调用add_button_press;

sub pop_up_add {
    ...
    my $add_but_2 = $add_frm_2->Button( 
        -text => "Add Record",
        -command => $session->postback("add_button_press"),
        -fOnt=> "{Arial} 12 {bold}") -> pack(
            -anchor => 'c',
            -pady => 6,
        );
    ...
}

validate creates the Toplevel widget $heap->{ih_mw};

validate创建Toplevel小部件$ heap - > {ih_mw};

sub validate {
    ...
    if( ! $valid ) {
        print "\n! valid entered\n\n";
        $heap->{label_text} .= "Add record anyway?";
        my $lt_ref = \$heap->{label_text};
    ...
        my $heap->{ih_mw} = $heap->{add_mw}->Toplevel( -title => "ih_mw");
    ... 
        if( Tk::Exists($heap->{ih_mw}) ) {
            print "\n\nih_mw exists in validate\n\n";
        } else {
            print "\n\nih_mw does not exist in validate\n\n";
        }
    ...
        my $ih_but1 = $heap->{ih_mw}->Button( -text => "Add",
            -fOnt=> 'vfont',
            -command => $session->postback("ih_button_1_press"),
            )->pack( -pady => 5 );
    ...
}

Pressing $ih_but1 results in this;

按$ ih_but1会导致此结果;

C:\scripts\alias\resource>alias_poe_V-3_0_par.pl

add button pressed

添加按钮按下

sub validate called

子验证叫

! valid entered

!有效输入

ih_mw exists in validate

ih_mw存在于验证中

ih_button_1 pressed

ih_mw does not exist in ih_button_1_press

在ih_button_1_press中不存在ih_mw

So the $heap->{ih_mw} widget seems to be unkown to the ih_button_1_press anonymous subroutine even with the inclusion of "($kernel, $session, $heap) = @_[KERNEL, SESSION, HEAP];"

因此,即使包含“($ kernel,$ session,$ heap)= @_ [KERNEL,SESSION,HEAP]”,$ heap - > {ih_mw}小部件似乎也不知道ih_button_1_press匿名子例程;“
