Hi Ramesh,

let me answer your questions:

1. When you activate the special characters through '123' the characters which are stored at the variable layoutSpecialOn are used and applied on the keyboard buttons. If you want to replace for example the (,),<,> keys with numeric characters than modify the string stored at layoutSpecialOn. Be aware that when you change it at ExtendedVirtualKeyboard::KeyboardQWERTZ this will also affect its derived keyboard layouts unless this variable is not overwritten there.

2. You can change the bounds of the keyboard buttons within the specific layout e.g. at ExtendedVirtualKeyboard::KeyboardQWERTZ

3. I need here more information from you. Do you want to create a complete new keyboard layout to support a new language. Those layouts can be switched through the globe button. Or do you want to add here a new button like the '123' button which shows different characters on the same keyboard layout?

Regards,

Julian

Here Using layoutSpecialOn  applied keyboard buttons.i added font property here but it is not displayed in layout

ExtendedVirtualKeybaord::Button.UpdateLayout  ->in this function added property

super( aSize );

Frame.Bounds.size = aSize;

if ( textView != null )
{
  textView.Bounds.size = aSize;
   textView.Font=Application::Application::FontL;
  }
   

 

but it is not reflect in layout

Hi Ramesh,

the method UpdateLayout() gets invoked automatically after the size of the component has been changed. It is recommended to only do here layouting. Despite from this the font is set inside UpdateViewState() by:

textView.Font = Appearance.Font;

If you want to change the font than change the font at the ExtendedVirtualKeyboard::KeyInputConfig autoobject you are using e.g. ExtendedVirtualKeyboard::DarkMultiConfig.Font

Regards,

Julian
