window.getSize() ???

[Redee]

RenderWindow win(VideoMode(400,200),"123");
Event ev;
win.setSize(Vector2u(150,150));
cout << win.GetSize().x << endl;
cout << win.GetSize().y << endl;
while(win.pollEvent(ev)){}
cout << win.GetSize().x << endl;
cout << win.GetSize().y << endl;

400
200
150
150

And question...
We directly call function to resize window, why window sizes changes only after Event logic.
Maybe some function can detect changed size before Event ?
I can get this using winAPI.... using win.getSystemHandle()... but its.... ok try do something )

[Redee]

You can do this simply like this solution >

#include <Windows.h>
#include <iostream>
using namespace std;
#include "SFML/Graphics.hpp"
using namespace sf;

RenderWindow wIn(VideoMode(400,200), "MyWindow");
wIn.SetSize(Vector2u(150,150));
WINDOWINFO wiInfo;
GetWindowInfo(wIn.getSystemHandle(), &wiInfo);
cout << "Window Render Area width" << endl;
cout << wiInfo.rcClient.right - wiInfo.rcClient.left << endl;
cout << "Window Render Area height" << endl;
cout << wiInfo.rcClient.bottom - wiInfo.rcClient.top << endl;

But for secret I its added to my Sfml Redee's mod )).

When resizing the window, you're actually telling Windows to resize the window. The window itself won't query it's size and rather wait for the resize event to happen/be processed (this way you're skipping all the logic from your second code snippet), which makes the whole thing a lot faster when working real-time with it.

[Redee]

In my example is actually for pre-Logic before game loop...
And its no often uses - only before build window and if you change border of window or in game options select and set new resolution.
Thats all and its fully working for me.

You original SFML code works for me; it outputs (on Windows 7 with SFML 2.3):

150
150
150
150

Here's a compilable version in case anyone else wants to try it:

#include <SFML/Graphics.hpp>
#include <iostream>

int main()
{
        sf::RenderWindow win(sf::VideoMode(400, 200), "123");
        sf::Event ev;
        win.setSize(sf::Vector2u(150, 150));
        std::cout << win.getSize().x << std::endl;
        std::cout << win.getSize().y << std::endl;
        while (win.pollEvent(ev)){}
        std::cout << win.getSize().x << std::endl;
        std::cout << win.getSize().y << std::endl;
        return EXIT_SUCCESS;
}

On which OS?

I'm sorry; I should have said.
I'm using Windows. That's Windows 7 with release version of SFML 2.3.

[Redee]

I used Sfml 2.1 WinXPsp3

[Hapax]

It's possible, then, that it has been fixed. You should try out v2.3 to see if it still causes this error for you.

[Redee]

Yes here in 2.3 version fixed this.
This implementation like I wrote above.

Its uses rcClient values too..
