I'm trying to find a way to tell what object fired my onClick event. I have a checkbox that currently fires once when the checkbox is clicked and fires twice when the label is clicked. I want to be able to ignore when the label is clicked.
I have found some code that is similar to what I want here which explains how to use a gxt FieldEvent, but i'm using a gxt BaseEvent and i'm not able to change it to a field event. Is there an equivalent function to .getTarget() for BaseEvents?
TLDR; Does anyone know how to do an equivalent of what's here but using gxt BaseEvent rather than FieldEvent?
According to the api here:
http://dev.sencha.com/deploy/gxt-2.2.5/docs/api/com/extjs/gxt/ui/client/event/BaseEvent.html
you should be able to call the getSource() method and then extract the name. Was this what you were looking for?

By using doClick() method, the action of a button can be triggered. Is there such a way to change combobox value when a button is clicked in java? Thank You.
As you didn't state the graphical framework I assume you use Swing, as it contains a doClick function.
The doClick() function is only used to emulate a button click programmatically, for example in testing. This will fire all actions that are normally associated with that button, however you need to register those yourself, using a listener.
Is there an equivalent for C's getch() in Android or Java? I want the execution to stop until the user does some action, like tap on the screen or maybe press one of the hardware buttons like volume control or whatever is available. Another option would be to show a modal message box window, which does not let the program continue until the user presses on OK. Is it possible to do this in a simple way in Android? What is the simplest way to get something equivalent to getch() function in android?
I need to be able to use this in a Thread as well
There's no getch() equivalent function/method in java.
You must event handlers to do that.
Like having click handler for button,Which let you to some stuff on onClick() method,Once you click the button.

There's an event listener for android like onCLickListener. Then you can also used Jdialog then set its .isEditable value to false like dialog.isEditable(false);
I've encountered next problem. I've got list of products and each product has button to open its QuickLook PopUp. I've created special event for this button, registered it in EventBus and trigger them. Everything seems good, but when I click one button, popup is shown not just for this item, but for all items, that are in list (I mean numbers of that "show"). This happens cause I have one Event-class for all these buttons, but can I somehow separate them one from another?
I just want to set some ID or something like that to every button and check this condition while triggering or (this would be even better) trigger only event, that I really need.
You don't need an EventBus for this. You can create a simple ClickHandler and attach it to your buttons. When you create a ClickHandler, you pass a product ID (or whatever you use to differentiate your products) to a method that shows your popup.
You can add productId to your Custom Event as a property. Event handler will check it and show only required product info.
I am making a input spinner component. It's almost working, I just was unable to get long mouse click in the up and down buttons.
Is it possible? If yes, how can I do that?

It has the feature you're looking for. You can either use the component it self or see how it implements the feature
Here is the scenario. I have an swing applet with tons of checkboxes. some of them are disabled/unchecked when checking another. Each ItemStateChange() event executes a method to parse the entire form for changes. Is there a way to tell if an ItemStateChange() event was triggered due to a mouse click or from a setSelected() call?
The ItemStateChange() for each checkbox has the standard parameter java.awt.event.ItemEvent evt
I'd like to only call the processOrder() method once when a box is clicked. Right now it fires for each change thats made, regardless of whether the change happened from setSelected(). Sometimes there are 10+ parseForm(); calls from a single click.
You can't tell whether the source of the event is a mouse click or a setSelected call from the ItemEvent.
It sounds like you have a loop in your check box logic. You might want to add a controller that handles the events and sets each checkbox yet ignores events that occur due to calling setSelected on other check boxes.
Is there a way to tell if an ItemStateChange() event was triggered due to a mouse click or from a setSelected() call?
If your application manually invokes the setSelected() method then you can use code like:
checkBox.removeItemListener(...);
checkBox.setSelected(...);
checkBox.addItemListener(...);
If you are able to change to use a MouseListener instead of an ItemListener and respond to the mouseClicked() event you will only receive the events for the checkbox selected by the user.
