Hi Ramesh,

I assume you want to colorize the text of the textkey47 different than at the other key buttons.

The color of the text is assigned within ExtendedVirtualKeyboard::Button.UpdateViewState():

textView.Color = Appearance.TextColor;

This does overwrite the assignment you make at loadLayoutFromString().

What you could do, is that you add an additional bool property at the ExtendedVirtual::Button e.g. call it SpecialColor. Set it inside the inspector on textkey47 to true. As a default it should be false. Than call inside OnSetSpecialColor InvalidateViewState() to request an UpdateViewState() call. Inside UpdateViewState() you can now check on this property to set for example the text color of textkey47 to red:

if ( textView != null )
{
  textView.String = String;
  textView.Font = Appearance.Font;
  textView.Color = Appearance.TextColor;

  if ( SpecialColor )
    textView.Color = #FF0000FF; // Set the text color to red
}

Hi Ramesh,

in general displaying glyphs with different height requires additional font resources. Be aware that especially in this case due to the huge font range this can result in a lot of additional flash memory. If thats not a problem for you than you can do the following:

1. Create a new font resource e.g. ExtendedVirtualKeyboard::FontL and make sure that its proper setup like ExtendedVirtualKeyboard::FontM but with different Height

2. Also do an exception for the font at ExtendedVirtualKeyboard::Button.UpdateViewState() by changing it the following way:

if ( textView != null )
{
  textView.String = String;
  textView.Font = Appearance.Font;
  textView.Color = Appearance.TextColor;

  if ( SpecialColor )
  {
    textView.Color = #FF0000FF; // Set the text color to red
    textView.Font = ExtendedVirtualKeyboard::FontL;
  }
}
