我試圖讓這個當你右鍵點擊,該行突出的藍色,然後你可以編輯或刪除該條目。但是,由於添加了滾動條,如果頁面滾動,則選擇將被偏移。尋找座標上滾動的帆布的Tkinter
我試圖0找到canvasx和canvasy,然後使用find_closest的建議的事情(,但是當我這樣做,它總是返回(1)不管是什麼。
Canvasx和canvasy似乎本地爲每個標籤,而不是帆布本身
from tkinter import *
def RightClick(event):
#Find widgets on the row that was right clicked
print(canvas.canvasy(event.y))
for widget in frame.winfo_children():
mouseClickY = event.y_root - root.winfo_y() - widget.winfo_height()
widgetTopY = widget.winfo_y()
widgetBottomY = widget.winfo_y() + widget.winfo_height()
if (widget.winfo_class() == "Label") and (mouseClickY > widgetTopY) and (mouseClickY < widgetBottomY):
#Highlight that row
if widget.cget("bg") != "#338fff":
widget.config(bg = "#338fff", fg="#FFFFFF")
#Deselect all rows
elif widget.winfo_class() == "Label":
widget.config(bg = "#FFFFFF", fg="#000000")
def onFrameConfigure(event):
canvas.configure(scrollregion=canvas.bbox("all"))
root = Tk()
root.bind("<Button-3>", RightClick)
canvas = Canvas(root, width = 1080, height=500)
frame = Frame(canvas)
scrollbar = Scrollbar(root, command=canvas.yview)
canvas.config(yscrollcommand=scrollbar.set)
canvas.grid(row=1,column=0,columnspan=5)
canvas.create_window((0,0), window=frame, anchor="nw",tags="frame")
scrollbar.grid(column=5,row=1,sticky="NS")
frame.bind("<Configure>", onFrameConfigure)
for countY in range(40):
for countX in range(6):
l = Label(frame, text=countX, width = 25, height = 1, bg="#FFFFFF")
l.grid(column=countX,row=countY+1)
也就是說waaaaay更多的代碼是必要的,再加上你的縮進被打破。請參閱[如何創建一個最小的,完整的和可驗證的示例](http://www.stackoverflow.com/help/mcve) –
對不起,我會解決這個問題。通常當我在這裏發帖時,我被告知要發佈更多代碼,所以我做了 – Mrchooch
我們只需要足夠的代碼來重現問題,沒有什麼更多。 –
