Hide Mouse Curser Globally From an Application

You can call an escape code to globally enable/disable the mouse cursor.



#define ESCAPECODEBASE 100000
#define MOUSECURSOR (ESCAPECODEBASE + 20)

DWORD old_cursor=0;
DWORD new_cursor=0;

// Get Cursor Status
ExtEscape(GetDC(NULL), MOUSECURSOR, 0, NULL, 4, (char*)&old_cursor);

// Disable Cursor
new_cursor=0;
ExtEscape(GetDC(NULL), MOUSECURSOR, 4, (char*)&new_cursor, 4, (char*)&old_cursor);

// Enable Cursor
new_cursor=1;
ExtEscape(GetDC(NULL), MOUSECURSOR, 4, (char*)&new_cursor, 4, (char*)&old_cursor);

Using escape codes is not supported on iMX6
