gwt virtual keyboard

[Amrutha]

I have created a login page and virtual keyboard using gwt designer.
When i click on show keyboard icon in login page, keyboard should come
there and if i press a key that particular key charactor or number
should appear in username field and password field.
How could i implement this using gwt?In short how could I implement a
gwt login page with virtual keyboard?

[Kanagaraj M]

There are 2 ways to do it.

1. Include the needed elements (keyboard, username, password, submit button) in a GWT Panel

  And add that panel to RootPanel

  Handle the button event

2. Put place holders in the login page

  As the sample project in eclipse does

 Handle the submit action in login page or form submit

Heii Kanagaraj,

 

      Thanks for your reply.I have added buttons in keyboard as images.Can you please tell me how can i get that particular button character in my username?How to code that in gwt?

[Kanagaraj M]

write a click event listener.

Attach the listener to all the buttons.

receive the event, find which button is clicked and add the respective character to text box

Heii Kanagaraj,

 

 I have added the code like this

Image image_1 =

new Image("Images/1.png");

image_1.addClickListener(

new ClickListener()

public void onClick(Widget sender){

textBox.setText((

"1" + sender.getTitle());

}

})

;

this code is working but when i click on this button it works only once when i try to click on it again it won't come in textbox.What should I do for that?

You are overriding the values in the text box,

you have to append with already existing value

[Amrutha Thomas]

can you please show me how to code that??

[Kanagaraj M]

yes.

but you could have added different images. right?

while adding the image, set the respective title

as imageA.setTitle("A"); imageB.setTitle("B") respectively

and use textBox.setText( textBox.getText()+sender.getTitle());

[Amrutha Thomas]

ohhh I have forgotten that Thanks yaar

[Amrutha Thomas]

how to code for the other keys like capslock,arrow keys,tab,shift,backspace,space bar

[Kanagaraj M]

for other keys

NativeEvent event = Document.get().createKeyDownEvent(...);

DomEvent.fireNativeEvent(event, this);

[Amrutha Thomas]

but how can I use this code for a virtual keyboard??

You can use a PopupPanel for this.
