如何使窗口自动调整大小？

Question

I am tried to see different sources that speak about dynamic resize of the window but nothing is really working with me. I tried the following code but as you will see in the figures below more than half of the window is empty when maximizing the window.

root.geometry('500x600')
root.title('Optimization Sphere')
root.resizable(True, True)

My guess is that you're using grid exclusively, or at least for the layout of the highest level of widgets.

With grid , rows and columns will expand or shrink to fit their contents as best they can. If there is extra space, that extra space will go unused.

You can configure grid to allocate space to one or more rows and one or more columns. As a rule of thumb when using grid , you should always do this for at least one row and at least one column. Typically that is the column with the largest widget -- a text widget, a canvas, a tree, something like that.

You control this by giving a row or column 'weight'. The weight tells grid what to do with extra space. The values are relative, so if you have one column with a weight of 1 and one with a weight of 3, the one with the weight of 3 will get three out of every four extra pixels.

In your case I'm guessing you want to give all extra space to column 1, which you would do like this:

root.grid_columnconfigure(1, weight=1)

Without seeing your actual code it's impossible to know if that's the exact right thing to do. However, the point remains that if you're using grid , you need to give a non-zero weight to at least one column if you want that column to expand to fill empty space.
