» 2025-06-03 22:58:46 No więc napisałem ale pozostało mi jeszcze pozycjonowanie kursora. Nie mam pomysłu jak rozwiązać ten problem. Skąd wziąć pozycję kursora? if( event.text.unicode == '\b' ) {
if( lines.size() > 0 && cursorPosition != sf::Vector2i( 0, 0 ) ) {
if( cursorPosition.x == 0 && cursorPosition.y > 0 ) {
if( lines[ cursorPosition.y - 1 ]->getString().toWideString().size() == 0 ) {
delete lines[ cursorPosition.y - 1 ];
lines[ cursorPosition.y - 1 ] = nullptr;
cursorPosition.y -= 1;
}
else {
std::wstring line = lines[ cursorPosition.y - 1 ]->getString().toWideString();
line.pop_back();
line = line + lines[ cursorPosition.y ]->getString().toWideString();
delete lines[ cursorPosition.y ];
lines[ cursorPosition.y ] = nullptr;
lines[ cursorPosition.y - 1 ]->setString( line );
}
lines = wrap_text( getTextFromLines() );

else if( cursorPosition.x > 0 ) {

» 2025-06-04 22:18:02 Dla pustej linii się wywala (miejsce z kodem oznaczyłem komentarzem "// backspace") A co tu w ogóle działa? Podaj dokładne kroki do reprodukcji jak chcesz pogadać o konkretnym problemie. |

» 2025-06-04 22:23:11 Działa wprowadzanie tekstu i dodawanie spacji oraz kasowanie tekstu ze środka linii. Ale nie rozumiem dlaczego backspace przed pustą linią nie działa no i ten enter też nie chce działać no chyba, że dodam L'\n" w następującej funkcji: std::wstring getTextFromLines() {
std::wstring text = L"";
for( int i = 0; i < lines.size(); i += 1 )
if( lines[ i ] != nullptr ) {
text = text + lines[ i ]->getString().toWideString() + L"\n";
}
return text;
}
Ale backspace i tak nie działa .. :-/ |

» 2025-06-04 22:33:25 Mam tu problem żeby w ogóle dodać pustą linię. Enter robi dziwne rzeczy i wywala program. lines = wrap_text(
L"A\n\nB"
); A
B Kursor w pustej linii, backspace kasuje "A". To ma więcej sensu: if( lines[ cursorPosition.y ]->getString().toWideString().size() == 0 ) { delete lines[ cursorPosition.y ]; lines[ cursorPosition.y ] = nullptr;
cursorPosition.x = lines[ cursorPosition.y - 1 ]->getString().getSize();
cursorPosition.y -= 1;
lines = wrap_text( getTextFromLines() );
} Drugi przypadek: Kursor na początku 3. linii, przed literą B. Backspace wywala program na pop_back(): int index = getIndex();
std::wstring line1 = lines[ cursorPosition.y - 1 ]->getString().toWideString();
line1.pop_back(); std::wstring line2 = lines[ cursorPosition.y ]->getString().toWideString(); Ten kod ma sens, natomiast linie miały mieć \n który chcesz tu usuwać, chyba że zdążyłeś zmienić koncepcję. |

» 2025-06-04 22:40:22 Ok. Dziękuję za odpowiedź :-) Już poprawiłem te linie i teraz działa. Pozostało tylko do zrobienia wrapowanie tekstu za kursorem. // edit teraz nie działa wprowadzanie znaków. Gdy wprowadza się znaki z klawiatury i linia przekroczy szerokość okna to ostatnie słowo trafia do nowej linii, gdy dalej wprowadza się znaki i kolejne słowo przekroczy dopuszczalną szerokość to też tworzy kolejnę linię.
