How to show the keypad without edit area or edit field?

Is there a way to show the keypad without showing edit area or edit filed?

I put an edit area(field) offscreen but keypad is also not shown... :(

Hi,

AFAIK, simplest way to do this is to create extremely small EditField as suggested in the topic below:

https://developer.tizen.org/forums/web-application-development/virtual-device-keyboard-api

“I use Tizen::Ui::Controls::EditField with very small Tizen::Graphics::Rectangle(0, 0, 1, 1) on Construct() and then ShowKeypad()/HideKeypad() when required.”

Thanks Alex,

 

I tried to do that, but the screen is cleared with black color when I show the keypad.

How can I prevent the black screen?

I want to display my contents instead of the edit area at the top area of screen and to show keypad at the bottom of screen.

Do you construct your EditField with INPUT_STYLE_OVERLAY or INPUT_STYLE_FULLSCREEN?

Yes sure, there is sample code in the documentation under  (Tizen::Ui::Controls::Keypad Class Reference )

Right. This class allows to display the keypad without EditField. But as far as I understand it covers all the screen with its own edit field. Am I wrong? Actually, I didn't use it before.

Yeah, full screen only AFAIK

For Overlay (half screen), you need editfield or editarea .. maybe if you cover the editfield with another UI like EditField -> Label as background image -> then the rest of UI ... it works and shows the overlay keypad when Editfield get selected in coding

 

 

Or maybe you hide the editfield when the keypad will show (keypad listener)

Or Maybe just have hidden editfield and set it selected in coding ...

I have no tried it before but I think it is possible

Hi, all
Here just one more minor suggestion:

You could construct small EditArea and place it on form below (where keypad will overlays EditArea ) and hide EditArea after,
So you could add in OnInitializing():
 pEditarea->Construct(Rectangle(0, 700, 1 , 1),INPUT_STYLE_OVERLAY);
 pEditarea->SetShowState(false);

And show keypad this way:
 pEditarea->SetShowState(true);
 pEditarea->ShowKeypad();
and hide this way:
 pEditarea->SetShowState(false);
 pEditarea->HideKeypad();

You will avoid constant 1x1 EditField in this case. Unfortunatelly if ShowState=false you are unable to use ShowKeyPad/HideKeypad methods for EditArea.

You can actually show keypad without any edit filed or edit area. All you have to do is bind to InputMethod instance and call ShowKeyPad() and HideKeyPad() methods when required.

Go through the InputMethod class in the documentation. There also is a sample program which shows keypad when a button has gained focus. In your case you have to handle when to show and hide keypad.

Pardon me about the previous comment. Class is InputConnection not InputMethod .
