#includeint main(int argc, char* argv[]) { BAlert *alert = new BAlert("Title", "Message", "OK"); alert->Go(); return 0; }
#includeThis code creates a BAlert object with a title "Title", a message "Message", two buttons "Yes" and "No", displays the alert to the user and waits for them to click one of the buttons. The Go() method returns an integer value corresponding to the index of the button that was clicked, so we can use it to determine which button was clicked and perform some action accordingly. In conclusion, BAlert is a useful class in C++ for displaying various messages to the user in the BeOS and Haiku operating systems. It is a part of the AppKit package library, which provides developers with various GUI components and tools to build graphical applications.int main(int argc, char* argv[]) { BAlert *alert = new BAlert("Title", "Message", "Yes", "No", NULL, B_WIDTH_AS_USUAL, B_WARNING_ALERT); int32 result = alert->Go(); if (result == 0) { // user clicked "Yes" button } else if (result == 1) { // user clicked "No" button } return 0; }
