I am working on a project and part of ask for:
add a CheckBox menu item Decrypt which can be checked for decrypt or unchecked for Encrypt. This item should be tied to the toggle button in the GUI. Both should reflect the current status of encrypting/decrypting in the application
which is I not sure how to begin with
well to start with, have you created a gui with a JCheckbox and a JToggleButton? If so start by getting your gui created, i'm assuming you are using swing??
Then add an action listener to the checkbox and the togglebutton. You can find a tutorial on action listeners here. Then in the action listener you can check the state of the checkbox and togglebutton and adjust as necessary.
Give this a shot, and post here if you run into problems.

Through DispatchGesture, I need to somehow click on the back button, but do it programmatically, without clicking on the button or reproduce finish(), only in another app
I found a code that only clicks on the given coordinates
Thanks in advance:)
UPDATE
I found this: Trigger back-button functionality on button click in Android, but I want to make a click from Service
I'm currently learning Android development from a book and I've come to the topic of radio buttons. The book explains that you handle radio button clicks (within a RadioGroup) using setOnCheckedChangeListener() with an anonymous OnCheckedChangeListener class as an argument.
However, according to the Android documentation you can set the onClick attribute on radio buttons to simply refer to a method of your design and handle clicks there.
Is there a reason to choose one over the other? What I'm asking is if there is some difference between the two that I'm missing, or if they simply both do the same thing.
setOnCheckedChangeListener() is listening to checked state, so if it is changed programmatically your code will be triggered. onClick listener only detects changes on checked state only if the element is clicked.
Is there a possibility using Java Swing to add in a existing running Swing application a button as an example. The action of the button to have a call to an existing method in that application. Maybe using xml to define the structure of the button.
You can do it. When any action triggered you can create the button and set the listener for it.
But best practice is to create the button and listener at the build time. Here you need to hide/set visibility to false initially and when any action triggered, set the visibility to true.
In Swing it was possible to connect action to a button and button was reflecting action's parameters like icon, enableness, text and so on.
Is this also possible with ControlsFX' Action?
If yes then how?
For an existing button you can use ActionUtils.configureButton(action, button).
To create a button bound to the action, use ActionUtils.createButton(action)
In Eclipse E4, detached view option is not available but this is very important requirement for our project, So i want to add popup menu in MPart to provide the functionality.
Please guide me how can i add popup menu in MPart. I tried adding it in application model but it seems i am doing something wrong.
Thanks in Advance!
Add a popup menu and handled menu item to the MPart in your .e4xmi
Make sure you get the id's correct. The handler will be the code you want to run
see here for an example:
