[英]Python ttk notebook showing selected tab wrongly
from tkinter import *
from tkinter import ttk
class MainGame(Frame):
def __init__(self, parent):
Frame.__init__(self, parent)
self.parent = parent
self.initUI()
def tab_change(self, event):
tab_id = self.page.index('current')
print(tab_id, self.page.tab(tab_id, 'text'))
def initUI(self):
global canvas
self.parent.title('PythonPage')
self.pack(fill = BOTH, expand = 1)
self.page = ttk.Notebook(self, width = 646 ,height = 629)
self.page1 = Frame(self)
self.page2 = Frame(self)
self.page.add(self.page1, text = 'Tab1')
self.page.add(self.page2, text = 'Tab2')
self.page.bind('<ButtonPress-1>', self.tab_change)
self.page.pack(expand = 0, anchor = 'w', side = 'top')
root = Tk()
root.geometry('925x650')
main = MainGame(root)
root.mainloop()
tab_change
can show their id and names, but not correctly. tab_change
可以显示其ID和名称,但显示不正确。
When Tab1
is clicked, I clicked Tab2
but it still print 0 Tab1
, it needs one more click to print 1 Tab2
. 单击Tab1
,我单击了Tab2
但它仍然打印0 Tab1
,还需0 Tab1
单击一次以打印1 Tab2
。
Tab2
click to Tab1
is the same, it needs one more click to show the current selected tab. Tab2
单击与Tab1
相同,需要再次单击以显示当前选定的选项卡。
I want to find why the tabs need double click? 我想找到为什么选项卡需要双击? And how can I get selected tab correctly by a single click? 怎样单击才能正确选择选项卡?
