我正在尝试将一个面板分成两个面板。 因此,Button1应该在一个面板中,而Button 2、3、4应该在另一面板中。
这是我的可运行代码,无法正确显示面板。

我不得不修改一下,但是尝试给每个面板一个自己的大小调整器,并在最后将它们组合在一起。另外,请使用描述性名称,否则它很快就会变成一团糟,很难理解。

Oof,其中一些panel和sizer变量名称很难遵循。
在处理wx时,最好跟踪哪些窗口(例如面板,按钮等)将位于其他窗口之内,并保持警惕,以了解如何声明父对象。每个。
例如,如果您有一个包含多个元素的面板(例如panel1
),则在实例化这些元素时,将其父元素都设置为panel1
。例如,创建self.button1
时,将其父级设置为panel1
(与其他按钮相同),因为您将它们都放入panel1
中。
这是因为wx会自然尝试在其父母内部安装窗户。当一个窗口的父元素是一个元素,但是一个大小调整程序试图将它放在另一个元素中时,事情就变得很麻烦了。很难完全遵循,但我想这就是您的问题所在。
使您的代码(a)更易于阅读/关注/调试,以及(b)更好地工作的另一件事是:不要害怕实例化多个sizer变量。更好的是,给他们起与他们正在组织的小组相匹配的名字!
我发现将__init__
函数分为三个部分很有帮助(这也可能对您有用):(1)从“顶层”实例化所有您需要的窗口/对象向下,为其分配正确的父窗口; (2)实例化所有的大小调整器,每个窗口包含其他元素; (3)从“底层”开始,将窗口添加到其父级大小调整器,在每个父级面板上调用SetSizer
,然后进行处理,直到为顶级窗口设置了主大小调整器为止。
如果这对您不可行,请随时向我发送消息,我们将看看是否可以解析出wx无法正常运行的原因。
