是否可以使用 TK 创建带有滚动条的文本区域，当您滚动另一个移动时，滚动条也会移动？

我要创建的是一个带有标题的文本区域，然后是行标题下方的文本区域，另一个是数据。当您在 Excel 中冻结窗格时，有点像。我在每行的一组数组中都有数据，所以我需要的是一种链接每个文本区域中的滚动条的方法，这样数据中的上下一个也控制行标题，反之亦然，左边右边的数据控制列标题，反之亦然。

可能不可能，但问也无妨

好的，所以我有一些代码，它几乎可以满足我的要求，但我需要一些帮助才能让它完全工作。代码示例显示，如果您移动一个滚动条，它确实控制另一个文本区域，反之亦然，但它不控制自己的文本区域，有没有办法将多个 xviews 添加到命令中，以便同时移动两个文本区域时间。提前致谢

这当然是可能的。使用滚动条的-command选项来调用一个过程。在该过程中，调用yview您要移动的每个文本区域。

更新

当我写下我的原始答案时，我没有仔细阅读以看到您使用的是 Perl/Tk——我假设是 Tcl/Tk。然而，同样的原则也适用。

下面的代码替换了第一个下面的代码$mw->focus;——它使用一个水平滚动条来控制两个文本小部件。

my $horiz = $mw->Scrollbar(-orient => 'horizontal');

my $f1 = $mw->Frame();
my $vert1 = $f1->Scrollbar();
my $text1 = $f1->ROText(
                    -height => 10, -wrap => 'none',
                    -yscrollcommand => [set => $vert1],
                    -xscrollcommand => [set => $horiz],
                );
$text1->insert('end', "$_\n") foreach @headers;
$text1->pack(-side => 'left');

$vert1->configure(-command => [yview => $text1]);
$vert1->pack(-side => 'left', -fill => 'y', -expand => 1);

my $f2 = $mw->Frame();
my $vert2 = $f2->Scrollbar();
my $text2 = $f2->ROText(
                    -height => 10, -wrap => 'none',
                    -yscrollcommand => [set => $vert2],
                    -xscrollcommand => [set => $horiz],
                );
$text2->insert('end', "$_\n") foreach @info;
$text2->pack(-side => 'left');

$vert2->configure(-command => [yview => $text2]);
$vert2->pack(-side => 'left', -fill => 'y', -expand => 1);

$horiz->configure(-command => sub { $text1->xview(@_); $text2->xview(@_) });

$f1->pack;
$f2->pack;
$horiz->pack(-fill => 'x', -expand => 1);

MainLoop;
exit 0;
