General / OS X: crash when resize window to minimal size
« on: January 30, 2015, 05:01:08 pm »
SFML from github (master).
When I try resize window to minimal size (i do it fast), program crashes.
UPD: I think is a bug of the OS, because with GLFW i've got same thing.
Code:

General / Re: Is it possible to make this resource manager handle all resource types?
« on: January 29, 2015, 05:53:03 pm »
i've updated my post, may be it helps
but i really have only basic thoughts about how to do this
i'm not cpp programmer, sorry =(
i think object destroyed (cause it on stack) and we need to store it on heap instead of stack (http://www.sfml-dev.org/tutorials/2.0/graphics-sprite.php#the-white-square-problem)
try this, but i'm summon good c++ programmer in this topic)
i've tested drawing, ant it's works fine

im newbie in c++, but may be it will work (it seems to work):
but if the object dies, pointer to this object still be in resourceHolder
UPD
insert pointer line should be
class ResourceManager
{
public:
template<typename Resource>
bool load(std::string address)
{
Resource temporaryResource;
bool success = temporaryResource.loadFromFile(address);
resourceHolder.insert( {address, &temporaryResource} ); // insert pointer instead of value
return success;
}
template<typename Resource>
Resource* get(std::string ID)
{
return static_cast<Resource *>(resourceHolder[ID]);
}
private:
std::map <std::string, void *> resourceHolder; // can store pointer to anything
};
// use
ResourceManager UltimateResourceManager;
if (!UltimateResourceManager.load<sf::Texture>("img.png")) return -2;
sf::Sprite sprite(*UltimateResourceManager.get<sf::Texture>("img.png"));
{
public:
template<typename Resource>
bool load(std::string address)
{
Resource temporaryResource;
bool success = temporaryResource.loadFromFile(address);
resourceHolder.insert( {address, &temporaryResource} ); // insert pointer instead of value
return success;
}
template<typename Resource>
Resource* get(std::string ID)
{
return static_cast<Resource *>(resourceHolder[ID]);
}
private:
std::map <std::string, void *> resourceHolder; // can store pointer to anything
};
// use
ResourceManager UltimateResourceManager;
if (!UltimateResourceManager.load<sf::Texture>("img.png")) return -2;
sf::Sprite sprite(*UltimateResourceManager.get<sf::Texture>("img.png"));

resourceHolder.insert( {address, static_cast<void *>(&temporaryResource)} );

General / Re: Can't build simple app on OS X (SFML from master)
« on: January 29, 2015, 03:00:42 pm »
oh of course
in first time i use dylibs instead of frameworks, and copy headers from include/ dir to /usr/local/include/
now i use frameworks, but compiler still look into /usr/local/include, which contain wrong headers =)
thank you!

Hi!
SFML compiled from sources (github master) using clang and libc++ (may be i do it wrong, but simple app with window compiles succefull).
When i try to compile anything with code:

General / Re: Window size on OS X & Retina display
« on: January 26, 2015, 05:58:25 pm »
It works, thank you!
But now window title looks horrible.
May be exists some method, that returns OS scale modifier? Eg for OS X & Retina modifier = 2, on non-retina is 1, and i just multiply all sizes in my app by this modifier (or if it = 2, load HD images)?

General / Window size on OS X & Retina display
« on: January 26, 2015, 05:02:26 pm »
Hi.
Tested on 2.2 (from sources) & github master.
Code below makes window with size 400x300:
Of course in real (hardware) pixels it have normal size (800x600 real pixels), but by default OS X scales resolution. Same problem with sprites & other.
So can the SFML detect that need to scale all sizes automatically when i run app on retina display and non-retina display?
