c - Windows - What can we deduce from a mouse click on something "clickable"? -

as title suggests, i'm asking can find out click on screen.

more precisely, can click on precise element (which can + symbol opening new tab on generic browser, or file , save as... elements on open office document) detected , return kind of string of has been clicked?

by working win32 api able detect if left button of mouse has been clicked:

for(character=1; character<=222; character++) {     if(getasynckeystate(character) == -32767) {         ...         switch(character) {             case vk_lbutton: ...; break;             ...         }     } } 

and when click detected, know has been clicked (or, @ least, name of window click happened):

    void whichwindow(file *f) {         hwnd foreground = getforegroundwindow();         char window_title[256];         if(foreground) {             getwindowtext(foreground, window_title, 256);             fputs(window_title, f);             getmenufromwindow(f, foreground);         }         else fputs("problem retrieving window's title name", f);     } 

yet, don't know what has been clicked.

you'll have figured out getting mouse click's coordinates useless me, unless know coordinates of can clickable on screen.

i checked windowsui automation, of in c# and, porpouses, i'd prefer stay in c.

lot of people told me use 1 of programs in web, said, i'd prefer use c, without including extern library.

so: there way find out if clicked "new file" on text editor, or "play" on vlc, using windows api?

you can hold of handle, text , classname of (child) window under mouse cursor logic like:

hwnd hwndf = getforegroundwindow(); if (hwndf != null) {   hwnd hwndc;     tchar szclassname[64], szwindowtext[256];     point pt;      getclassname(hwndf, szclassname, _countof(szclassname));    // main window     getwindowtext(hwndf, szwindowtext, _countof(szwindowtext)); // main window      getcursorpos(&pt);          // in screen coordinates     screentoclient(hwndf, &pt); // in client coordinates of main window     hwndc = childwindowfrompointex(hwndf, pt, cwp_all);     if (hwndc != null && hwndc != hwndf)     {   getclassname(hwndc, szclassname, _countof(szclassname));    // child window         getwindowtext(hwndc, szwindowtext, _countof(szwindowtext)); // child window     } }
