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 / 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 !

General / (CodeBlocksSetup) point_gxx_personality_v0 can't be located in libstdc++-6.dll

« on: September 30, 2013, 12:14:06 pm »

HI!
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 !
