How to make class method wait for user input from gui
Hello,
I have a program with a gui and a different class named Search with a static method named paging().
This paging method retrieves some results and shows them using pagination,
so, it prints first e.x 10 results and then asks the user if he wants to continue to the next page, previous, quit or jump to a page.
I have buttons for previous, next page etc. on the gui, so I want the paging() method to wait until the user clicks a button.
What is the right way to do this?
Re: How to make class method wait for user input from gui
Don't start the method until the user presses the button. That is the natural way that GUI works.so I want the paging() method to wait until the user clicks a button.
If you don't understand my answer, don't ignore it, ask a question.
Re: How to make class method wait for user input from gui
There is another button that starts the paging() method, but then it waits for user input.
If the user presses next page then it retrieves the next 10 results, prints them and asks the user again if he wants to go to previous, next etc

How and where does the program ask the user any question?asks the user again
Is there a prompt in a small window?
Is there a message written to a text field in the GUI?
Or somewhere else?

Is the paging method running on its own thread?

Yes

One way to coordinate between threads is to us the CountDownLatch class. There is a sample program in the API doc for the class.
