Re: sir i have boolean variable i want if mouse is clicked on it...
There are some limitations to this approach. The mechanical action of the switch can only be Switch Until Released or Latch Until Released. For any other mechanical action, you can tell when it was pressed or when it was released, but not both. If you need to use local variables for your button, you can only use Switch Until Released (locals don't work with latch actions). Switch Until Released and Latch Until Released limit the switch to a momentary-contact switch. If you need a toggle switch, you need an event structure. Using an event structure gives you a lot more flexibility. You can use a toggle switch. You can check if the button was held while turning it either off or on or both.
Re: sir i have boolean variable i want if mouse is clicked on it...
For those who don't have the ability to create event structures, it's pretty easy to do the old-fashioned way. Create a while loop with a shift register and initialise it with the ms tick count. Each time round the loop, check the Boolean and if it is True, keep the existing shift register value, otherwise update the register with the current ms tick count. Compare the current ms tick count with the original value plus 2000 and if it's greater, exit the loop and write True to the second Boolean. The loop only needs to cycle every 100 ms or so so it's hardly a big drain on your processor...

Ben: I didn't go through your code, but once your LED goes on, it stays on, even if the next time you press the button it's for less than 2 seconds.
Re: sir i have boolean variable i want if mouse is clicked on it...
You are correct! The orignal question was not exaclty clear on what should happen to clear the output boolean. My example simply toggles the state of the output boolean when the control boolean is held down for more than 2 seconds. Ben
Re: sir i have boolean variable i want if mouse is clicked on it...
Nirmal: I think the question asked how to indicate that a button was held down for more than 2 seconds. Your example just lights the LED two seconds after the button was pressed and doesn't check how long the button was held down. To see how long a button is held down, you should use an event structure. Look at Ben's example or my example.
