python-3.x - wxpython 不能选择好的面板进行缩放
问题描述
当我需要绘制缩放时选择面板时，我在 wxpython 中有此应用程序 wxpython 无法在正确的面板中绘制 在同一面板中绘制
解决方案
从哪儿开始？
在LeftPanelBottom你已经定义
canvas_panel = LeftPanelTop(self)
self.canvas_panel = LeftPanelTop(self)
self.zoom_panel = MiddlePanelTop(parent=self)
所以那是 2 个画布面板，然后是混乱以及您将slap bang 放在里面sizer的事实，其中已经加载到. MiddlePanelTopLeftPanelBottomLeftPanelTopLeftPanel
但主要问题是关于inheritance. 因为几乎所有东西都被定义为class它自己的权利，甚至是按钮，试图找到一条通往MiddlePanelTop逃脱我的道路。也许其他人可以在这里插话，因为我迷路了。
简单且明显非 Pythonic 的方法是只使用一个global变量。
下面，我使用一个global叫做Zoom.
注意我还更改path了文件，在适当的地方
编辑：我已经在类中解码了你的类，并添加了适当的self条目，这样我们就可以访问它们。
结果，该Left面板现在也可以按照我想的那样运行。
我注意到Right和MiddlePanelBottom面板仍然存在不一致、缺少项目和固定位置。
