Thanks Everyone!

SO , I'm doing the wrong thing !
I will read on proper package production and hope I get it fixed soon .

BTW can SFML do that ? I mean press a key ?
Or is it impossible and needs hardware (keyboard in this case) to do it ?
Thanks !

Window / How to simulate keyboard/mouse press with SFML?
« on: March 07, 2014, 06:12:33 pm »
HI Everyone !
Is it possible to simulate a key press with SFML ?
I mean can SFML press a key for me ?

The reason I want this is that I'm writing a program which waits for some time (entered by user) and then runs a kernel command . (Linux Ubuntu 13)
But sometimes when the command is "sudo apt-get install ..." it requires a password and a confirmation which is done by pressing 'y' ;
Do you think I'm doing the right thing ?
Is there a better solution to do this or I should keep looking for key press simulation ?

+ :
I tried searching using forum's search BUT I faced this message :

Database Error
Please try again. If you come back to this error screen, report the error to an administrator.

Who is this administrator ?

Window / Re: Can't save and load ContextSettings and WindowHandle
« on: October 22, 2013, 01:49:19 am »
Thanks Ixrec !

I saved the window's properties one by one (size , position , title + settings) and it worked .

By the way , about that reference .

First I tried to send the object itself , but my "SaveCurrentState ()" caused a problem .
It opened a .hpp file : noncopyable.hpp
I searched in Google and I found  out a reference sign will solve the problem , so I used it .

I still don't know why .
The reason I asked it is that I'm looking for a simpler description of what the problem was and how it was solved .
Can you help me again ? Thanks !

Window / Can't save and load ContextSettings and WindowHandle
« on: October 22, 2013, 12:51:21 am »
HI !
I'm beginner and trying to write a simple app which creates a basic window based on properties the user enters .
Now I want to try to save the current state and load it later , thus I'm using a struct :
struct SLInfo
    sf::ContextSettings winMainSettings ; //winMain.getSettings ()
    sf::WindowHandle winMainSystemHandle ; //winMain.getSystemHandle ()

and a function to save :
int SaveCurrentState (sf::RenderWindow & winMain)
    SLInfo Info ;
    ofstream SaveFile ("some_file" , ios::binary) ;
    Info.winMainSettings = winMain.getSettings () ;
    Info.winMainSystemHandle = winMain.getSystemHandle () ;
    SaveFile.write (reinterpret_cast <char *> (& Info) , sizeof (Info)) ;
    return 1 ;
(is that refrence sign (&) before winMain correct?)
(Most of the code is omitted so that it looks simple and easier for you to check it)

and a function to load :
SLInfo LoadFile (string FileName)
    ifstream LoadLoc (FileName.c_str () , ios::binary) ;
    SLInfo Loader ;
    LoadLoc.read (reinterpret_cast <char *> (& Loader) , sizeof (Loader)) ;
    return Loader ;

Then in another function I open the window like this :
SLInfo winMainInfo ;
    string FileName ;
    cout << "\nEnter file name :\n" ;
    cin >> FileName ;
    winMainInfo = LoadFile (FileName.c_str ()) ;
    sf::RenderWindow winMain (winMainInfo.winMainSystemHandle , winMainInfo.winMainSettings) ;
(+ while window.isOpen () and event handlings , I omitted those parts too)

But when I run it (using Code::Blocks 12.11) I see these messages in console :
Failed to set pixel format for device context -- cannot creat OpenGL context
Failed to activate the window's context
Failed to activate the window's context
And I see no window at all .
Thanks in advanced for helping.
And if there is any additional info on my code needs to be provided let me know .
Thanks .

Graphics / I can't draw a sprite in RenderWindow
« on: October 19, 2013, 12:00:21 pm »
HI !
I am new to SFML .
I wanted to make a window and show a picture inside it .
I create the window correctly and the picture is loaded correctly , BUT I still can't display the sprite .
What I did is I created a RenderWindow and I tried to loadFromFile a sprite , BUT I saw an error indicating its not possible , so I loadeFromFileED a texture and setTextureED the sprite .
BUT I still can't observe the picture .
This is my code :
#include <SFML/graphics.hpp>
#include <iostream>

using std :: cout ;

int main ()
    sf::RenderWindow winMain (sf::VideoMode(800,600),"Test") ;
    sf::Texture winTexture ;
    if (!winTexture.loadFromFile("Untitled.jpg"))
        cout << "ERROR opening Untitled.jpg" ;
    sf::Sprite winSprite ;
    winSprite.setTexture(winTexture) ;
    winMain.display() ;
    while (winMain.isOpen())
        sf::Event winEvent ;
        while (winMain.pollEvent(winEvent))
            winMain.draw(winSprite) ;
            winTexture.update (winMain) ;
            switch (winEvent.type)
            case sf::Event::Closed :
                winMain.close() ;
                break ;
Thnaks !

System / cout operator << doesn't work for getElapsedTime ()
« on: October 02, 2013, 08:56:06 pm »
HI !
I'm new to sfml .
I was just testing time functions and I tried to use this :
cout << clock.getElapsedTime () ;
then i saw this error : "no match for operator << ..."

I tried this :
cout << (sf::Int64) clock.getElapsedTime () ;
BUT I got invalid cast error .

I'm wondering if there is any way to output elapsed time directly without converting it to sf::Time .
Thanks !

Thanks eXpl0it3r and Laurent !
You can't imagine how happy I am !
It's fixed , Thanks !

Laurent thanks BUT it didn't fix it , the same error appears .
and eXpl0it3r doesn't codeblocks use MinGW ?
I have a folder called MinGW in my CodeBlocks folder , so I didn't download TDM .
By the way I am downloading it and I will tell you about that .
Thanks !

I'm beginnger !
I have read the tutorial on setting up sfml (2.1) with CodeBlocks and I pasted the sample code (The one which draws a green circle with caption "IT WORKS") and CodeBlocks messaged : 0 errors , 0 warnings .
But when I ran the program I get this error :
"The program can't start because sfml-graphics-2.dll is missing from our computer."
So I copied all the .dll s in bin folder (from sfml) to debug folder of my project , in the same folder that the executable is created .

Then that error gone and a new one appears :
"The procedure entry point_gxx_personality_v0 could not be located in the dynamic link library libstdc++-6.dll ."

I am using CodeBlocks 12.11 gcc 4.7.1 windows 32 bit .
THank YOU !
