I have set the tabindex of TexInput controls in my Adobe Air works fine with tab key. Now I want to do the same with the enter key. I mean when I press enter key in the TextInput, next control should be selected.
In C# we can do the same with SendKeys and as per my knowledge there is not such way in Adobe Air.
Here is my added event
// get key presses only when the textfield is being edited
inputText.addEventListener(KeyboardEvent.KEY_DOWN,handler);
function handler(event:KeyboardEvent){
// if the key is ENTER
if(event.charCode == 13){
// WHAT ???
}
}
Find the instance with next/previous tabIndex
Depending on what control you are using, either call setFocus() method on this control (if it has one), or set the focus property of the stage to this instance. Set it to null if you want to remove focus at all.

I have created a JTable in NetBeans IDE. I want to add a new row to the table when the user gets to the lower right-hand corner of the table and presses the TAB key. I have tried NetBeans IDE options of changing the property for keyPressed, keyReleased and keyTyped, but nothing happens. Here is what I tried.
private void tblInterestIncomeKeyPressed(java.awt.event.KeyEvent evt)
{
if (evt.getKeyCode() == KeyEvent.VK_TAB)
{
System.out.println("Released tab key");
model.addRow(new Object[]
{
""
});
System.out.println("Got to this point");
}
}
I am trying to teach myself. I have seen other suggestions on this website, but they don't pertain to NetBeans IDE GUI creation. Thanks for any help.
Swing components use Key Bindings to bind a KeyStroke to an Action. The default Action for the Tab key is to move to the next cell. So you will need to create a custom Action.
You can create the custom Action by extending AbstractAction and adding your logic to the actionPerformed() method. You would then need to replace the current key binding to map to your own Action. Check out Key Bindings for example code on how to replace the bindings.
Or you can check out Table Tabbing. This uses a wrapper class to help make the key bindings process easier so all you need to implement is the logic in the actionPerformed() method.
This example shows how to replace the default Tab Action with a custom Action that will only tab to cells that are editable. You would need to customize this Action to add a new row to the TableModel.
How do I specify which button on the form is the default button which will be pressed when someone presses Enter from anywhere on the screen?
You can't do this in oracle forms with normal functionality.
The only thing you can do if you really want to accomplish this is to re-map your enter key see the following link on how to do this.
Then you can map your enter key to a key-trigger and in that key-trigger you can put the code you want to execute when the enter-key is pressed.
The only downside to this is that in every application the enter key is pressed the same key-trigger will be triggered if it exists in your application. So you can't use this method to only use the enter key in 1 form and normal use (go to the next field) in the other applications. Then you have to make in every application that key-trigger with the code next_item;
In a registration page,i want to move to next field,when i click tab from keyboard.I have implemented ENTER key for submnission,but i cant move to next field when pressing TAB
Setting the tabIndex to sequential values should be enough, maybe tabEnabled too.....
textfieldOne.tabIndex=1;
textfieldTwo.tabIndex=2;
textfieldOne.tabEnabled=true;
textfieldTwo.tabEnabled=true;
I am working on one enterprise app.
In that, I need to open one popup on one shortcut key, which is the combination of Alt+AnyCharKey.
So when I press that key with Alt, for different char keys, different numbers or characters is typed in TextInput.
Suppose If I press Alt+A, it prints 1 in TextInput.
So problem is, when I capture the shortcut key and opens a popup and by setting focus on TextInput of that popup, that number is typed in TextInput.
So how can I disable that Alt+Key combination in TextInput ???
Simple preventDefault on keyDown should help, I think
protected function textinput_keyDownHandler(event:KeyboardEvent):void
{
if (event.altKey)
event.preventDefault();
}
I have a method called checkKeyCode(obj) which simply takes the character you type into a textbox and replaces it with its keyCode.
This method is called from onkeydown attribute of textbox input (onkeydown="return checkKeyCode(this)").
The problem is then I want to be able to press tab and focus to the next element. I don't have to know the element's id or name or tag. Basically I want to combine my method's functionality with the default functionality of browser when you press Tab key (which sets focus to the next element in the form).
Can this be done. If so how?
Any help would be greatly appreciated.
Check the keycode in your handler and if the value is 9, it's a tab. Exit your handler if it is and return false.
Also, don't use the onkeydown event. Use onkeyup instead.
