使用 CodeBlock 在 WxSmith gui 编程中向 wxPanel 添加布局后程序崩溃
Program crashed after adding a layout to a wxPanel in WxSmith gui programming with CodeBlock
我正在使用 CodeBlock 中的 WxSmith 学习图形用户界面编程 IDE。我按照以下步骤创建了一个示例项目
- 使用 WxSmith 版本 3.0 创建一个 WxSmith 项目
- 在项目的默认主框架中添加一个3列的box sizer
- 向每列添加 2 个按钮和 1 个面板
- 将 WxBoxSizer 添加到面板
- 构建项目并 运行，构建成功但生成 运行 时间错误。
使用 GDB 时，出现以下错误。

找到一些防止崩溃的程序。
- 不要将布局控件直接添加到框架中。先添加面板再添加sizer。
- 保持默认大小 属性 为包含布局控件的面板打开。 Final UI 控件可以有特定的高度和宽度。根据我的经验，如果我们有 UI 带有自定义 width/height 的控制器，我们无法为面板设置自己的宽度和高度，这些控制器被放置在类似 box sizer 的布局中。
在避免上述情况后，我能够运行程序没有崩溃。
