Graphics / Re: Getting a blank image

Thankfully I think I figured it out. I move win.update(win) into the outer while loop, before win.clear();

Graphics / Getting a blank image

« on: June 07, 2021, 01:03:14 pm »

Hi, I would like to save a screenshot of the window but end up with getting a blank image

sf::RenderWindow win(sf::VideoMode(500, 1000), "Window 1");
sf::Texture texture;
sf::Image image;
texture.create(win.getSize().x, win.getSize().y);
texture.update(win);

 while (win.isOpen()) {
    sf::Event event{};
    while (win.pollEvent(event)) {
      if (event == sf::Event::Closed) {
        win.close();
      }
    }
    win.clear();
    win.draw(SomeShape);

    image = texture.copyToImage();                         // Assign texture to image
    image.saveToFile("../Saved Image/Logo.png");     // Able to generate the image file, but it's blank...

    win.display();
  }
}

I tried to put the two lines with comments at different position, for instance before win.clear or after win.display, but I still got a blank image.

Window / 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!

I'm using vscode on a Mac, everything works fine until I updated the OS last night... Still working on it...
