How do I use the custom keyboard that's provided in TouchGFX templates.

[ALin]

Hello,

I am fairly new to the TouchGFX designer and am trying to build an application where I can copy the contents typed using the keyboard on a screen(Custom Keyboard application provided with the designer) to another TextArea . I would really appreciate any help regarding this problem.

Hi,

What have you tried to so far do and what are you having issues with?

Just to return to this.

Keyboard has a getBuffer() method that returns the keyboard buffer.

 Unicode::UnicodeChar* getBuffer() const
 {
 return buffer;
 }

You can then use Unicode::strncpy() to copy this to whatever buffer you're using with your TextAreaWithOneWildcard

 /**
 * @fn static uint16_t Unicode::strncpy(UnicodeChar* RESTRICT dst, const UnicodeChar* RESTRICT src, uint16_t maxchars);
 *
 * @brief Copy a string to a destination buffer, UnicodeChar to UnicodeChar version.
 *
 * Copy a string to a destination buffer, UnicodeChar to UnicodeChar version. Stops if it
 * encounters a zero-termination, in which case the zero-termination is included in
 * the destination string. Otherwise copies maxchars.
 *
 * @param [out] dst The destination buffer. Must have a size of at least maxchars.
 * @param [in] src The source string (UnicodeChars)
 * @param maxchars Maximum number of characters to copy.
 *
 * @return The number of characters copied (excluding zero-termination if encountered)
 *
 * @warning If there is no null-termination among the first n UnicodeChars of src,
 * the string placed in destination will NOT be zero-terminated!
 */
 static uint16_t strncpy(UnicodeChar* RESTRICT dst, const UnicodeChar* RESTRICT src, uint16_t maxchars);
