Question

我使用Tkinter库在python中创建了一个GUI applcaition。我已禁用显示窗口的大小调整。我使用的所有按钮和小部件都正在我正在开发的系统上正确显示。但是当我在其他系统上运行应用程序时，小部件的大小和位置变得一团糟。

请大家建议我如何删除此问题并使应用程序系统独立？

我已附上代码文件。请在这里帮忙。

我没有足够的声誉来添加图片，请在此处提供帮助。

凌乱我意味着小部件之间的空间不均匀，大小也不同。

Answer 1

我实际上已经调试了这个问题。以下是需要修改的内容： -

在网格中配置行和列时。使用Grid.columnconfigure和Grid.rowconfigure，权重为1或大于1。
小部件的width属性可能因使用的小部件类型而异。在具有文本值的小部件的情况下，宽度以字符数指定，并且如果小部件具有图像，则以像素指定宽度。

现在，当我将代码从Windows移动到Linux并运行时，GUI的外观看起来与众不同。第一个原因是我之前没有使用上面第1点中提到的网格方法。其次，字体类型和大小起着至关重要的作用。如果您没有明确设置默认字体类型和大小，那么GUI会选择运行它的系统的默认字体类型。

我在Windows和Linux上手动给出了相同的字体大小和字体类型，然后按钮显示相同。

我希望答案很有帮助。在这里，我修改后粘贴代码。

Answer 2

我认为你可以设置几何： root.geometry("500x400+100+100")

您必须在启动Tk实例后添加它！上面代码中的500表示宽度，此处400表示高度，其他2个数字表示高度的位置屏幕上的窗口!!
