wxPython抢先一步

Question

我在wxPython中使用sizers布局我的表单时遇到了一些挑战，如果有人能给我在布局表单方面领先一步的话，我将不胜感激。

​

​

请分享源码。

谢谢

Answer 1

在设计复杂的gui时，我不会手动调整大小。请使用wxglade，然后手动进行自定义。

这花了15分钟，包括错误(我没有填写列表控件，抱歉)：

​

​

这是我遵循的流程：

1) Add a Frame widget, select a wx.Frame.  

2) Customize wx.Frame properties:  
     Give the Frame a MenuBar (the property dialog for the menubar appears).  
     Customize MenuBar: Add File, Edit...  
     Go back to the Frame properties' View (click the Frame icon on the wxglade Tree View).  
     (not nice but it's the way I found to go in and out from Menu and StatusBar dialogs).  
     Give the wx.Frame a StatusBar. Go back (click the Frame icon in the wxglade Tree View).  

3) Create 3 vertical slots from the default BoxSizer (right-click on the sizer + add * 3)
      1st slot: 
          Add a BoxSizer with 5 horizontal slots
          Set proportion=0 to the sizer, set border=5 and mark wxALL
          Add 4 Buttons and a Spacer in those slots
          Mark EXPAND and set proportion=1 in the Spacer properties.

      2nd slot:
          Add a SplitterWindow. Select Vertical type.
          Optionally set border=5 with wxALL
          Add a BoxSizer to each section of the SplitterWindow
          At its left, add a ListCtrl
          At its right, add a NoteBook
          Customize NoteBook:
              Add 4 sheets.
              Add BoxSizer with 2 vertical slots to first notebook sheet.
                  1st slot: insert a wx.Panel.
                  2nd slot: add a BoxSizer with 3 horizontal slots.
                      Set proportion=0 to the sizer.
                      Add 2 buttons and 1 Spacer in those slots.
                      Mark EXPAND and set proportion=1 in the Spacer properties.

      3rd slot:
          Add a BoxSizer with 5 horizontal slots.
          Set proportion=0 to the sizer, set border=5 with wxALL
          Add 2 Buttons, 1 Spacer and 2 Buttons more.
          Mark EXPAND and set proportion=1 in the Spacer properties.

4) Give background colour to the Frame.
  (Choose wisely, you still have 5 minutes left of the 15 allotted).

最后，自定义标签、大小和小部件名称等。

保存wxGlade文件以备将来更改，并生成Python文件(在顶部的Application对话框中)。

技巧：不修改生成的文件，而是在另一个文件中导入帧并子类化以编码其功能。

最后一点：根据我的经验，在尺寸和背景方面，Linux和有一些不同之处。在Linux中，不要使用步骤3中指出的默认框架的BoxSizer，而是在它上面添加一个wx.Panel，将一个BoxSizer添加到面板中，然后从这个大小继续构建。

只是为了好玩，我决定看看我需要多长时间才能写出类似的代码。我花了大约35分钟的时间。我跳过了菜单栏。哦，好吧。下面是代码：
