我在畫布中添加了畫布和滾動條。 但是有些東西錯誤導致滾動條關閉(底部底部不可見),我繪製的文本關閉。任何人都可以告訴我最新的問題?我想在畫布上,填補了整個幀(顯然沒有滾動條)使用tkinter畫布的畫布佈局

非常感謝!我有5行,因爲我需要框架'黃色'和'藍色'比其餘rowspan = 4更大。有三排他們會有相同的尺寸,我不想那樣。 – krusty
我剛剛意識到我可以使用rowconfigure weight來實現同樣的只有三行,它更易於閱讀。謝謝! – krusty
@krusty:我想你誤解了網格是如何工作的。每一行都獨立於其他行。你可以有三行,每一行都有不同的高度。如果你跨越一行沒有任何東西的行,那行高度爲零。 –
