» 2025-06-17 03:14:26 Znalazłem jeszcze jednego Buga. Gdy linia kończy się enterem, to trzeba przesunąć dwa razy w prawo by dotrzeć do nowej linii. To samo z cofaniem się, gdy mamy kursor na pozycji cursorPosition.x == 0 to trzeba dwa razy cofnąć. Zauważyłem, że jest to powiązane ze znakami nowej linii. Dodałem więc odpowiednie obliczenia indeksu ostatniego znaku w danej linii i teraz wszystko działa. Kod zamieszczam poniżej. Zaktualizowane funkcje:setCursorLeft();
setCursorRight(); Resztę kodu możesz znaleźć w repozytorium:https://github.com/tBane1995/Easy-Notepad.git#include <SFML/Graphics.hpp>

» 2025-06-17 03:51:09 Mam jeszcze jednego Buga i nie wiem jak go namierzyć. Gdy na końcu tekstu wprowadzamy enter to nie aktualizuje się widok. tzn. kursor jest poza obszarem renderu. float scrollbar_value;
if( scrollbar != nullptr ) {
float min_val_on_screen = scrollbar->scroll_value;
int lines_on_screen = int( window->getSize().y / font.getLineSpacing( characterSize ) );
float max_val_on_screen = min_val_on_screen + lines_on_screen;
std::cout << "cur: " << cursorPosition.y << "\n";
std::cout << "min: " << min_val_on_screen << "\n";
std::cout << "lines on screen: " << lines_on_screen << "\n";
std::cout << "max: " << max_val_on_screen << "\n";
if( cursorPosition.y < min_val_on_screen )
scrollbar_value = cursorPosition.y;
else if( cursorPosition.y > max_val_on_screen - 1 )
scrollbar_value = cursorPosition.y - int( window->getSize().y / font.getLineSpacing( characterSize ) - 2 );

scrollbar_value = scrollbar->scroll_value;

» 2025-06-17 06:58:13 Już wiem jaki jest błąd ale jak go namierzyć to nie mam pojęcia :-/ Źle oblicza cursorPosition po enterach i przez to źle scrolluje tekst
cur: 0
cur: 0
cur: 1
cur: 2
cur: 3
cur: 4
cur: 5

» 2025-06-18 09:50:43 Mogę zaoferować za pomoc z tym cursorem 200 złotych.
To jak pomoże ktoś?
Bo ja sam tego raczej nie naprawię :-/ |

» 2025-06-18 14:40:27 Myślę, że powinieneś zastanowić się co jest dla ciebie zbyt trudne w tym kodzie i zastanowić się jak go zorganizować 'inaczej', abyś mógł z nim sprawnie pracować. Jeżeli doszedłeś do punktu, w którym nie jesteś w stanie rozwijać własnego kodu, to powinieneś zrobić krok w tył i zastanowić się jak zrobić kod 'prościej' / jak go podzielić na mniejsze funkcjonalne klocki, albo podnieść swoje umiejętności w debugowania. Rozwiązanie tego problemu może ujawnić trzy kolejne problemy więc... to dobre ćwiczenie dla Ciebie, aby poprawić swoje umiejętności debugowania kodu.
Pieniądze w tym wypadku nic nie pomogą, bo zapłacisz teraz i za dwa dni będziesz miał kolejny problem z tym samym kodem, który również będzie kosztował. Tym samym za chwilę albo zatrudnisz juniora albo zapłacisz za licencję AI, którą będziesz katował tak długo aż rozwiąże problem. |

» 2025-06-19 03:37:38 ChatGPT już wykupiłem i nie zawsze jest dla mnie pomocny. Jakieś proste kody ogarnia, ale przy tych dłuższych się gubi. Jestem amatorem jeśli chodzi o programowanie i nie mam żadnego nauczyciela ani mentora. Jestem skłonny zapłacić te 200 zł, bo to nie dużo za pomoc a nuż ktoś pomoże i taki kod będę mógł na spokojnie przeanalizować i nauczyć się czegoś nowego.

» 2025-06-19 03:41:00 Dobra udało się, trzeba było poprawić kod w dwóch miejscach. Po 1. Należy poprawić funkcję odpowiedzialną za pozycjonowanie kursora:void setCursorPosition( sf::Vector2i cursor_position ) {
cursorPosition = cursor_position;
if( cursor_position == sf::Vector2i( 0, 0 ) ) {
cursor.setPosition( sf::Vector2f( 0, 0 ) );
return;
}
if( lines.empty() ) {
cursor.setPosition( sf::Vector2f( 0, 0 ) );
return;
}
std::wstring line =( cursorPosition.y < lines.size() ) ? lines[ cursorPosition.y ]->getString().toWideString()
: L"";
if( line.size() == 0 ) {
sf::Vector2f charPos( 0,( cursorPosition.y - scrollbar->scroll_value ) * font.getLineSpacing( characterSize ) );
cursor.setPosition( charPos );
return;
}
if( cursor_position.x <= line.size() ) {
sf::Vector2f charPos = lines[ cursorPosition.y ]->findCharacterPos( cursor_position.x );
std::cout << charPos.x << ", " << charPos.y << "\n";
cursor.setPosition( charPos );
return;
}
sf::Vector2f endPos = lines[ cursorPosition.y ]->findCharacterPos( line.size() );
cursor.setPosition( endPos );
}
else if( event.type == sf::Event::TextEntered ) {
int index = getCursorIndex( cursorPosition );
if( event.text.unicode == 8 ) {
if( index > 0 && !text.empty() ) {
if( selection == nullptr || selection->start_index == selection->end_index ) {
text.erase( index - 1, 1 );
index -= 1;
}
else {
text.erase( std::min( selection->start_index, selection->end_index ), std::abs( selection->end_index - selection->start_index ) );
index = std::min( selection->start_index, selection->end_index );
}
if( selection != nullptr ) {
delete selection;
selection = nullptr;
}
}
if( !lines.empty() ) {
for( auto & t: lines )
delete t;
}
lines.clear();
lines = wrap_text( window->getSize().x - 16, text );
cursorPosition = getCursorFromIndex( index );
generateScrollbar();
linesPositioning();
setCursorPosition( cursorPosition );
}
else if( event.text.unicode == 13 ) {
text.insert( index, 1, L'\n' );
cursorPosition.x = 0;
cursorPosition.y += 1;
if( !lines.empty() ) {
for( auto & t: lines )
delete t;
}
lines.clear();
lines = wrap_text( window->getSize().x - 16, text );
generateScrollbar();
linesPositioning();
setCursorPosition( cursorPosition );
}

text.insert( index, 1, L'\t' );
index += 1;

for( auto & t: lines )
delete t;
}
lines.clear();
lines = wrap_text( window->getSize().x - 16, text );
cursorPosition = getCursorFromIndex( index );
generateScrollbar();
linesPositioning();
setCursorPosition( cursorPosition );
}
else {
wchar_t character = static_cast < wchar_t >( event.text.unicode );
if( character >= 32 && character != 127 ) {
if( selection != nullptr && selection->start_index != selection->end_index ) {
text.erase( std::min( selection->start_index, selection->end_index ), std::abs( selection->end_index - selection->start_index ) );
index = std::min( selection->start_index, selection->end_index );
delete selection;
selection = nullptr;
}
text.insert( index, 1, character );

» 2025-06-19 03:57:48 Napisałem. Aplikacja pozwala edytować tekst, zaznaczać, kopiować, wklejać. Obsługiwane skróty klawiszowe. Tekst można zaznaczać kursorem lub poprzez skrót klawiszowy shift+strzałka. Ctrl+a pozwala zaznaczyć cały tekst. Ctrl+c kopiować, ctrl+x wycinać a ctrl+v wklejać tekst.
