The text area cannot display correctly when the user inputs a character array.
Hello every,
I created some text areas to display the file name, which comes from a character array provided by the user's input.
Below are the configuration settings for each text area.
1.text area
2.Texts->Typographies
3.code
3.1.text area define in class
touchgfx::TextAreaWithOneWildcard data06_text;
touchgfx::TextAreaWithOneWildcard data05_text;
touchgfx::TextAreaWithOneWildcard data04_text;
touchgfx::TextAreaWithOneWildcard data03_text;
touchgfx::TextAreaWithOneWildcard data02_text;
touchgfx::TextAreaWithOneWildcard data01_text;
static const uint16_t DATA06_TEXT_SIZE = 32;
touchgfx::Unicode::UnicodeChar data06_textBuffer[DATA06_TEXT_SIZE];
static const uint16_t DATA05_TEXT_SIZE = 32;
touchgfx::Unicode::UnicodeChar data05_textBuffer[DATA05_TEXT_SIZE];
static const uint16_t DATA04_TEXT_SIZE = 32;
touchgfx::Unicode::UnicodeChar data04_textBuffer[DATA04_TEXT_SIZE];
static const uint16_t DATA03_TEXT_SIZE = 32;
touchgfx::Unicode::UnicodeChar data03_textBuffer[DATA03_TEXT_SIZE];
static const uint16_t DATA02_TEXT_SIZE = 32;
touchgfx::Unicode::UnicodeChar data02_textBuffer[DATA02_TEXT_SIZE];
static const uint16_t DATA01_TEXT_SIZE = 32;
touchgfx::Unicode::UnicodeChar data01_textBuffer[DATA01_TEXT_SIZE];
3.2.display the file name
void selectFileScreenView::SendOpenFileTitle(const uint16_t index, const char *title)
{
//Debug_Printf("title:%s", title);
switch(index){
case 0:
Unicode::snprintf(data01_textBuffer, DATA01_TEXT_SIZE, "%s", title);
data01_text.invalidate();
break;
case 1:
Unicode::snprintf(data02_textBuffer, DATA02_TEXT_SIZE, "%s", title);
data02_text.invalidate();
break;
case 2:
Unicode::snprintf(data03_textBuffer, DATA03_TEXT_SIZE, "%s", title);
data03_text.invalidate();
break;
case 3:
Unicode::snprintf(data04_textBuffer, DATA04_TEXT_SIZE, "%s", title);
data04_text.invalidate();
break;
case 4:
Unicode::snprintf(data05_textBuffer, DATA05_TEXT_SIZE, "%s", title);
data05_text.invalidate();
break;
case 5:
Unicode::snprintf(data06_textBuffer, DATA06_TEXT_SIZE, "%s", title);
data06_text.invalidate();
break;
default:
break;
}
}
4.result
I’m sure that the const char *title is correct, but all the text areas display "???????????". Please help me fix this. Thanks in advance
