I've not found the dataChange handler for spark label, as it was for mx:Label.
Is there ability to catch changing the text of spark label?
Any help will be appreciated.
There is no change event for a Label AFAIK.
You have two opportunities:
Create your own componentt wich is based on Label, overrride set text property and dispatch Change event from it (or any other event you like).
Or
If you change Label text somwhere and want some unrelated component to be notified of the change simply dispatch event on a Label control instance
var title:Label;
...
title.text = "Some text";
title.dispatchEvent(new Event(Event.CHANGE));

In my code I have bound the defaultProperty of a button to some other properties like so:
BooleanBinding isAddResourceButtonDefault
= resourceNameTextField.focusedProperty().or(
resourceTypeComboBox.focusedProperty()).or(
divisibleResourceCheckbox.focusedProperty().or(
maxInstancesTextField.focusedProperty()).or(
addResourceButton.focusedProperty()));
addResourceButton.defaultButtonProperty().bind(isAddResourceButtonDefault);
The problem is that the addResourceButton won't fire absolutely any events on pushing Enter - neither OnAction, nor OnKeyPressed.
The default property gets set just fine - I double checked (using output and ScenicView). ScenicView also doesn't show any events being fired upon hitting keys. Any ideas?
I believe TextFields (and other TextInputControls) process and consume key events that occur on them. So pressing Enter on a text field will not fire an action event on the default button (because the key event never reaches the Scene).
If you are just trying to fire the button's action event handler when enter is pressed in one of the text fields, just add the same event handler to the text fields. E.g.
EventHandler<ActionEvent> addResourceHandler = event -> {
System.out.println("Add resource");
// ...
};
addResourceButton.setOnAction(addResourceHandler);
resourceNameTextField.setOnAction(addResourceHandler);
maxInstancesTextField.setOnAction(addResourceHandler);
can i create an event on Ckedtor where as soon as i write some thing in textarea of editor the same should dynamically update on another label below it using jquery.

I have a grid with editable fields (by means of CellEditung plugin).
I need to execute some function each time the content of a field of the grid is changing (I need it for a text field and for a combo box field).
Unfortunately I cannot use event 'edit' since it is fired only when edition process is finished (edited field goes out of focus), and I need capture text changing events (~= keyup event while editing text field).
Anybody knows a way to do that?
You can use cellclick event listener to get the record.
cellclick:function( thisObj, td, cellIndex, record, tr, rowIndex, e, eOpts ){
console.log(record);
}
if you need to do something on selection change, you could wire to one of the methods in to the gridSelectionModel
also you could wire a function to columnModel
or just cellclick or celldblclick
I have called a leave event for a a text box and in it called another buttons event named Retrieve button. so now I just want to check in this retrieve button event weather the text box's leave event is called or not?
When you call the retrieve button event from the text box leave (blur) event you could simply add a flag into the eventArgs that you can check in the retrieve button. This flag would only be set when you implicitly call the retrieve button even from the text box leave event.
This would mean that if the retrieve event is called from other places the flag would not be set so you could tell that the call definitely came from the button leave event.
In my program, I want to change the inputType of Ext.form.TextField when clicking another control. You an imagine about the password textfield and a "Show/Hide" button. I register event for the "Show/Hide" button to change the display form of password. But because that textfield has already rendered before this button click event was fired, so the inputType of it dis not affect immediately. Can you help me? Thank in advance.
The config options are not properties in the sense of C# for example, changing them does nothing because there's no way for the object to know you've changed them, which is usually why you have the many set* methods.
However there is no method for this for TextField so you'll probably have to re-create the object with the required configuration.
