  10.2. How do I get a Button to actively change under my mouse pointer?

  You should specify both an '-image' and an '-activeimage' configuration option either when calling the ->Button() method or in a later separate call to the ->configure() method.

  Here is an example excerpted from the basic_demo script that comes with the Tk kit: #!/usr/local/bin/perl -w use Tk; $main = MainWindow->new; $QPBFile = "demos/images/QuitPB.xpm"; $QPBaFile = "demos/images/QuitPBa.xpm"; $QuitPB = $main->Pixmap('-file' => Tk->findINC("$QPBFile")); $QuitPBa = $main->Pixmap('-file' => Tk->findINC("$QPBaFile")); my $but = $main->Button('-image' => $QuitPB, '-activeimage' => $QuitPBa, '-command' => sub { $main->destroy } ) -> pack; MainLoop; __END__译文:

  10.2. 如何设置按钮随鼠标指向的动态变化?

  这需要在调用->Button()方法创建按钮的时候,或者是后来使用->configure()方法的时候,设定“-image”和“-activeimage”两个选项。

  下面是从Tk包中的basic_demo脚本中摘录出来的一个例子:

  #!/usr/local/bin/perl -w

  use Tk;

  $main = MainWindow->new;

  $QPBFile = "demos/images/QuitPB.xpm";

  $QPBaFile = "demos/images/QuitPBa.xpm";

  $QuitPB = $main->Pixmap('-file' => Tk->findINC("$QPBFile"));

  $QuitPBa = $main->Pixmap('-file' => Tk->findINC("$QPBaFile"));

  my $but = $main->Button('-image' => $QuitPB,

  '-activeimage' => $QuitPBa,

  '-command' => sub { $main->destroy }

  ) -> pack;

  MainLoop;

  __END__

日版宠物情人2017的插曲,很带节奏感,日语的,女生唱的。 最后听见是在第8集的时候女主手割伤了,然后男主用嘴帮她吸了一下,插曲就出来了。 歌手:Def...

兄弟共妻,我成了他们夜里的美食

老钟家的两个儿子很特别,就是跟其他的人不太一样,魔一般的执着。兄弟俩都到了要结婚的年龄了,不管自家老爹怎么磨破嘴皮子,兄弟俩说不娶就不娶,老父母为兄弟两操碎了心...
