嗨，我是wxpython新手。还有我上载问题但尚未解决的一个星期。

if __name__=="__main__":
    app = MyApp(False)
    app.MainLoop()

此代码的进度如下

在textctrl中输入“型号名称”
搜索“相关模型”并将按钮绑定到事件（以获取特定的模型名称）
从listctrl绑定到事件中选择一个“模型”（以获取组合框的元素）
和组合框的列表填充有相关列表（列表元素从sqlie带来）
选择一个组合框元素并显示相关图像（图像为GIF动画）

以下是我的问题

当我选择组合框列表并且在面板上播放Animated GIF时。并选择组合框的另一个元素，动画GIF播放另一个元素，并且图像重叠

以下代码...图像转换和播放代码...我将此代码称为“ IMAGE” （我将所有Animated GIF保存到了webp并在那时转换为gif）

    erim = Image.open('./image/image_error_ramp/%s.webp' % imageno) 
    erim.info.pop('background',None)
    erim.save('./image/image_error_ramp/%s.gif' % imageno,save_all=True, loop=0)
    anim = Animation('./image/image_error_ramp/%s.gif' % imageno)
    ctrl = AnimationCtrl(self.Panel_err_image, -1,anim, pos=(35,40))
    ctrl.Play()
    os.remove('./image/image_error_ramp/%s.gif' % imageno)

所以我认为也许可以解决将“ IMAGE”代码移到构造函数代码下方的问题（因为存在 init 构造函数。）

    # constructor
    def __init__(self, parent, id=wx.ID_ANY, title="Search", pos=wx.DefaultPosition, size=(1500,650), style=wx.DEFAULT_FRAME_STYLE, name=""):

        IMAGE CODE

，在这里（在构造函数代码下面），我无法获取imageno（imageno是图像的名称。该名称来自sqlite，因此我从组合框中选择了一个元素，但无法从中获得任何响应组合框）
我的问题是这个
- 我可以使用combobox从构造函数代码下面的sqlite获取图像名称吗？
- 或其他原始位置（在注释“ IMAGE”下方）“动画GIF不重叠”的任何代码？
ps。罗宾·邓恩（Robin Dunnn）和萨克森州（Rox of Saxony）这周教了我这个问题但是我不明白，也很沮丧.....

玩得开心

Answer 1

很难知道从哪里开始这个答案，因为存在编码错误，逻辑错误，而且我不知道数据是什么样子。
但是，有几件事很突出。

sqlite查询需要fetch才能返回行/行
使用fetchone（），fetchmany（n）或fetchall（）
如果测试print()是您的朋友，如果不使用IDE
打印结果以查看您的期望
始终假设可能发生了错误，请以是否为例进行测试或尝试例如
初始化变量，尤其是在if语句中设置它们的情况下
假设测试可能失败。

也就是说，我赞扬您的go for it态度，但是您可以以较小的步骤做到这一点。掌握所有步骤，然后再尝试将所有步骤放在一起。

这是您的代码的一个版本，带有许多警告。
我不知道您的数据或数据结构。
我首先在数据库中创建了一些虚拟记录。
我不知道你的目标或逻辑。
只有我需要解决的问题才能获得基本运行的程序，并且我删除了一些有关图像处理的代码，以帮助我而不是您。
希望您可以在下面的代码中找到一些好处。
建议您在代码上使用“ diff”，而不要使用代码，以查看发生了什么变化。
