[STR New] Link: http://www.fltk.org/str.php?L1731 Version: 2.0-feature I'm looking for a way to repositioning the mouse cursor. I need this feature to implement the fly mode in a openGL window in order to allow the camera rotation caturing the mouse movement events. The problem is that when mouse cursor hit the border of the screen it does not generate any other useful event to track the mouse movement. That is, I continue to move mouse but the cursor coordinate offset does not change from 0 (because mouse cursor keep it's position on the screen). So I used to place the cursor at the center of the capturing window at every event, hidding the cursor itself, and monitoring the offset from the center of the render window. Actually I've to do this calling a X or Win32 API directly intead of using an FLTK call. Somebody has posted this solution at http://www.mail-archive.com/[EMAIL PROTECTED]/msg00023.html , in which he propose the function jump_mouse as int jump_cursor (int new_x, int new_y) { #if defined WIN32 BOOL result = SetCursorPos(new_x, new_y); if (result) return 0; // OK #elif defined __APPLE__ CGPoint new_pos; CGEventErr err; new_pos.x = new_x; new_pos.y = new_y; err = CGWarpMouseCursorPosition(new_pos); if (!err) return 0; // OK #else // Assume this is Xlib Window rootwindow = DefaultRootWindow(fl_display); XWarpPointer(fl_display, rootwindow, rootwindow, 0, 0, 0, 0, new_x, new_y); return 0; // Assume OK #endif return -1; // Fail } // jump_cursor Would be nice if it could be tested and integrated in the next version of fltk...
