New submission from Jason Yang <jason990...@outlook.com>:
Button no response when clicked if mouse move into tooltip and tooltip
destroyed for Python 3.9.9/3.10.1 and tkinter 8.6.12
You can check it by moving mouse into button, then move to tooltip after it
shown, then click button and you won't get response for button clicked, but
"Leave". It is OK for lower version of Python/tkinter.
```python
import sys
from datetime import datetime
import tkinter as tk
class Tooltip(object):
"""
create a tooltip for a given widget
"""
def __init__(self, widget, text='widget info'):
self.waittime = 500 # miliseconds
self.widget = widget
self.text = text
self.widget.bind("<Enter>", self.enter)
self.widget.bind("<Leave>", self.leave)
self.widget.bind("<ButtonPress>", self.leave)
self.id = None
self.top = None
def enter(self, event=None):
print(now(), "Enter")
self.schedule()
def leave(self, event=None):
print(now(), "Leave")
self.unschedule()
self.hidetip()
def schedule(self):
self.unschedule()
self.id = self.widget.after(self.waittime, self.showtip)
def unschedule(self):
id = self.id
self.id = None
if id:
self.widget.after_cancel(id)
def showtip(self, event=None):
x = y = 0
x, y, cx, cy = self.widget.bbox("insert")
x += self.widget.winfo_rootx() + self.widget.winfo_width()//2
y += self.widget.winfo_rooty() + self.widget.winfo_height()//2
self.top = tk.Toplevel(self.widget)
self.top.wm_overrideredirect(True)
self.top.wm_geometry("+%d+%d" % (x, y))
label = tk.Label(self.top, text=self.text, bd=1, font=font,
relief='solid')
label.pack(ipadx=1)
def hidetip(self):
top = self.top
self.top = None
if top:
top.destroy()
def now():
return datetime.now().strftime("%H:%M:%S")
print(f"Python version : {sys.version.split(' ')[0]}")
print(f"tkinter version: {tk.Tcl().eval('info patchlevel')}")
font = ("Courier New", 40)
root = tk.Tk()
button = tk.Button(root, text="button", font=font,
command=lambda:print(now(), 'Button clicked'))
button.pack(padx=10, pady=5)
tooltip = Tooltip(button, 'This is button 1')
root.mainloop()
```
