objective c - NsWorkspace iconForFile returns image of low quality -


i'm using iconforfile: selector of nsworkspace class, returns image of low quality.

can tell me why happening? there switch or flag framework return image in different format...

the docs state returned icon's size 32x32, can use -[nsimage setsize:] , may load larger representation:

nsimage * iconimage = [[nsworkspace sharedworkspace] iconforfile:file]; [iconimage setsize:nsmakesize(128, 128)];

you can use icon services (e.g. geticonreffromfileinfo) or quicklook (e.g. qlthumbnailimagecreate) file's icon or preview icon @ larger size.

i using windows.h library's getasynckeystate function define key pushed on keyboard . here program returns int value of pushed key example. #include <iostream> #include <windows.h> using namespace std; int main (){ char i; for(i=8;i<190;i++){ if(getasynckeystate(i)== -32767){ cout<<int (i)<<endl; } } return 0; } but trying make opengl simple game , function appeared slow . there function not need cycle 180 times , if statement . thanks you're trying make opengl game, you're going use glfw. if that's case can away using glfwgetkey() such: if (glfwgetkey(glfw_key_up) == glfw_press) {...} if (glfwgetkey(glfw_key_down) == glfw_press) {...} that method nicely explained in tutorial 6 opengl-tutorial.org . should start first tutorial of beginners tutorials , later intermediate tutorials . if you're going make win32 window can listen wm_keydown or wm_keyup messages , virtua
