Able To Open a New Window But Not Close it
« on: June 07, 2021, 02:25:17 am »
Hi, I create a feature that if the user clicks the menu, a window pops out. I'm able to display the pop window but not close it.
class PopWindow {
private:
    sf::RenderWindow popWin;
    sf::Color popWinColor = sf::Color(50, 50, 50);

public:
    // Default constructor
    PopWindow();

    // While pop is Open
    int winOpen();
};
#include "PopWindow.h"

PopWindow::PopWindow() {
  popWin.create(sf::VideoMode(500, 500), "Pop Window");
}

int PopWindow::winOpen() {
  sf::Event popWinEvent{};
  while (popWin.isOpen()) {
    while (popWin.pollEvent(popWinEvent)) {
      if (popWinEvent.type == sf::Event::Closed || sf::Keyboard::isKeyPressed(sf::Keyboard::F2)) {
        popWin.close();
      }
      popWin.clear(popWinColor);
      popWin.display();
    }
  }
  return 0;
}

The weird thing is if I declare a PopWindow object and call object.winOpen() in the main class, everything works fine, however, if the object is declared in one of other classes, I can only open a new window but not close it.

How to handle events for multiple windows?
Thanks for your help!

You have to combine the event processing, update and drawing of both windows in one main/game loop.

Maybe not the best design, but one way would be to change the while (popWin.isOpen()) to a if(popWin.isOpen()) and call it from your main window loop every frame.
