Mouse click without use bind - ATARI_LIVE - Oct-01-2020
I have code with bind which I do not like.
is there another way than bind?
I am looking for counting when the mouse or touchscreen is pressed and hold for about 3 seconds to respond.
Thanks!

There is no built-in way to handle Drag and drop, and the only way to do this is to create the functionality yourself.
Quote:is there another way than bind?
The only possible way to do this without bind is to create a low level listener (and this is essentially a home-grown bind), and you don't want to go there unless you thoroughly understand the interrupt process. Bind is a way to capture interrupts within your code, and you need not be afraid of them.
for drag and drop, you need to bind:
- Button press (In tkinter this looks like <ButtonPress-1> )
- Button move (In tkinter this looks like <B1-Motion> )
- Button release (In tkinter this looks like <ButtonRelease-1>
There are many examples of how to do this. It's quite simple to create your own,
you need create hooks for start, move and, stop activity.
Do a google search for: 'drag and drop for tkinter'
Please not that there is DRag and Drop support comming in ptrhon release 3.9.0 see: https://docs.python.org/3.9/library/tkinter.dnd.html
expected release in just 4 days (Oct 5) or you can download and install the release
see: https://pythoninsider.blogspot.com/2020/09/python-390rc2-is-now-available-for.html?utm_source=feedburner&utm_medium=feed&utm_campaign=Feed%3A+PythonInsider+%28Python+Insider%29
you can find the code for this
if you can't find a suitable example with google,
come back, post your code, and I or another mod/admin will help you write one.
Finally: Perhaps it's time to consider my favorite wxpython, Kivy, or Qt5

Where is drag and drop mentioned?
If you want to force a 3 second continuous touch before doing some action, you'll need to at least bind to touch and release and use an after to call your eventual callback.
from tkinter import *
after_id = None
root = Tk()
def press_cb(event):
global after_id
after_id = root.after(3000, after_cb)
def release_cb(event):
global after_id
if after_id is not None:
root.after_cancel(after_id)
after_id = None
def after_cb():
"""Do whatever"""
print('Leg go of me!!')
root.bind('<ButtonPress-1>', press_cb)
root.bind('<ButtonRelease-1>', release_cb)Or you could combine a few things.from tkinter import *
root = Tk()
def press_cb(event=None):
global lp_id
if event is None:
print('Let go my Eggo!')
lp_id = None
elif event.type == EventType.ButtonPress:
lp_id = root.after(3000, press_cb)
elif lp_id:
root.after_cancel(lp_id)
lp_id = None
root.bind('<ButtonPress-1>', press_cb)
root.bind('<ButtonRelease-1>', press_cb)It would be useful to know what you are trying to do, what you have tried to do, and why you are unhappy with what you've done. At least I am confused about what you are asking.

Quote:deanhystad asked: Where is drag and drop mentioned?Somehow, I answered to the wrong thread.
Now I have to find the correct one, and move the post.
RE: Mouse click without use bind - ATARI_LIVE - Oct-02-2020
Thanks for this and I am sorry for I missed to explained, I do not discuss about drag and drop. I talk about like press button and hold that's it.
Like when I press and hold for 3 sec then open the menu.
thanks again!
Let say for example:
if mousepress == 1:
count = count + 1
else:
count = 0
if count > 10 and count < 20:
Print("Still holding")
if count > 50 and count < 60:
print("That's enough!")
if count > 100:
Print ("Fine! I am quitting!")
exit()The bind do not to continue to pass when press and hold.

No one can?
RE: Mouse click without use bind - deanhystad - Oct-06-2020
I provided an example of how you can use bind to execute a delayed event. The mouse does not do hold/repeat like the keyboard, and even if it did, counting is a poor way to measure time.

That's works but almost!... not for me. I really thankful for this.
