TKinter 樣式和 Treeview 單擊問題

Question

我在 TKinter 中掙扎於樣式我的主要問題是您無法單擊樹視圖中的任何內容。

要測試，只需按“按測試”按鈕

出於某種原因，它看起來像 style.theme_create 接管了我的樹視圖小部件，無論我嘗試什么，我似乎都無法找到解決方案。 我嘗試激活光標、selection_set、focus_set 等。

如果我評論樣式，我可以點擊，但不能點擊。

我對 python 還是很陌生，希望得到一些見解。

我嘗試了 t1.bind('') 並試圖找到一個選定的樣式，但似乎無法使其工作，綁定本身不起作用。 我已經閱讀了文檔，但所有與選擇相關的嘗試似乎都失敗了。

這是我整個應用程序的一個縮略部分，但仍然有效。

Answer 1

問題：無法單擊樹視圖中的任何內容。
使用.theme_create禁用Treeview selected樣式。

---

Click 正在工作，您可以通過將回調綁定到事件'<Button...來驗證這一點。

    def on_selected(event):
        print('on_selected{}'.format(event))

    t1.bind('<ButtonRelease-1>', on_selected)

參考：

• widget.bind(event, handler)

  對於每個小部件，您可以將 Python 函數和方法綁定到事件。 如果小部件中發生與事件描述匹配的事件，則使用描述該事件的對象調用給定的處理程序。

您正在失去'selected'樣式或'!selected'樣式變得相同。 因此，如果您單擊一行，則不會發生顏色變化。

解決方案：
為新theme的Treeview小部件顯式設置'selected'樣式。

style.theme_create("fclassic", parent="alt",
                   settings={
                        'Treeview': {
                            'map': {
                                'background': [('!selected', 'blue'), ('selected', 'red')],
                                'foreground': [('selected', 'black')],
                                'font': [('selected', ("Century Gothic", 10, 'bold'))],
                            }  # end 'map'
                        }  # end 'Treeview'
                   }  # end settings
                   )
