我有一個包含 Matplotlib 條形圖的 PySimpleGUI 視窗。我最近向它添加了一個事件，允許用戶單擊一個欄并訪問基于欄標簽的功能。這很好用……直到我在非 matplotlib 區域（例如我的 PSG 按鈕）中單擊一下。在做了一些測驗之后，這個問題似乎只有在我呼叫一個新的、不同的視窗函式作為 on_click 事件函式運行的結果時才會發生。在我的示例中，如果我洗掉 another_window()，則單擊列印條形名稱或點擊 PSG 中的按鈕不會出現問題。問題是我需要觸發其他視窗并能夠回傳到正常運行的主視窗。我做錯了什么？提前致謝！

uj5u.com熱心網友回復：
不知道有什么問題fig.canvas.mpl_connect。我的建議不是在事件處理程式中創建一個新視窗，而是為新視窗生成一個到 main_window 的事件。
def on_click(event, win):
ax = event.inaxes
x = event.xdata
lbls = ax.get_xticklabels()
idx = int(x.round())
lbl = lbls[idx]
print('bar name is ', lbl.get_text())
win.write_event_value('Another', None)
cid = fig.canvas.mpl_connect('button_press_event', lambda event, win=windowMain:on_click(event, win))
while True:
event, values = windowMain.read()
if event == '-STORE BUTTON1-':
print('store part')
if event == '-RETRIEVE BUTTON1-':
print('retrieve part')
if event == sg.WIN_CLOSED or event == 'Exit' or event == '-EXIT BUTTON1-':
windowMain.Close()
break
elif event == 'Another':
another_window()
