1)Tk没有集成的拼写检查器。你可能对PyEnchant感兴趣。
2)3)4)没有那么难(请忘记我之前使用wxPython的建议)。您可以将tag_config作为文本小部件的insert方法的第三个参数传递。它定义此选择的配置。
请参阅以下代码,这些代码改编自Scrolledtext示例和effbot,后者是关于Tk的最佳参考。
Tkinter文本小部件非常强大,但是您必须自己完成一些高级功能。它没有内置的拼写检查或用于粗体文本的内置按钮等,但它们很容易实现。所有的功能都在小部件中,您只需要知道如何做到这一点。
下面的示例为您提供了一个按钮,用于切换突出显示文本的粗体状态--选择一个字符范围,然后单击该按钮以添加和删除粗体属性。你应该很容易扩展这个例子的字体和颜色。
拼写检查也很容易。下面的示例使用/usr/share/dict/words中的单词(这在Windows7上几乎肯定不存在,所以您需要提供一个合适的单词列表),这相当简单,因为它只在您按下空格键时进行拼写检查,但这只是为了将示例的代码大小保持在最小级别。在现实世界中,当你做拼写检查的时候,你会想更聪明一点。
