wxPython中的listctrl 如何在指定的列加入进度条

arzen

ListCtrl是比较简单的列表控件，操作起来没有Grid复杂，但要是想在指定的列中显示一个进度条，如迅雷等下载工具，显示一个下载进度，如何去实现呢？

能不能继承ListCtrl在OnPaint时进行处理呢？我试着

但一拖动滚动就有问题。这样的需求能用Grid实现吗？我是指在每行加上进度条

limodou

Grid好象是可以的。还有就是可以考虑使用scrolledwindow自已实现一个类似的

请问大神们，如何实现窗口框架下wx.ListCtrl，实现右键选择复制或修改，能在复制窗口列表内容到其他地方，如下图：
