Member Function Documentation

int Laxkit::CoreXlibPointer::eventFilter ( EventData **  events_ret, XEvent *  xev, anXWindow *  ww, int &  isinput  )

virtual

Return 1 if event is absorbed, and nothing else should try to parse it. Return 0 for event ignored.

Parameters:

ww	The target window for the event
isinput	Set to 1 if the processed event is input related

Reimplemented from Laxkit::LaxDevice.

References Laxkit::LaxMouse::buttoncount, Laxkit::LaxMouse::buttonPressed(), and Laxkit::LaxMouse::buttonReleased().

int Laxkit::CoreXlibPointer::getInfo ( anXWindow *  win, int *  screen, anXWindow **  child, int *  x, int *  y, unsigned int *  mods, double *  pressure, double *  tiltx, double *  tilty  )

virtual

Get information about the mouse state.

If you pass NULL for any field, then that field is ignored.

If win!=NULL, then return coordinates in win space. If the window is not on the same screen as the mouse, then return 1, and only screen gets set.

Otherwise return screen coordinates. The screen the mouse is actually in gets set.

Return 0 for success, or 1 for mouse not on same screen, or other number for mouse info not available for some reason.

Implements Laxkit::LaxMouse.

int Laxkit::CoreXlibPointer::grabDevice ( anXWindow *  win )

virtual

Return 0 for success, 1 for failure.

Reimplemented from Laxkit::LaxMouse.

References Laxkit::anXApp::app.

int Laxkit::CoreXlibPointer::selectForWindow ( anXWindow *  win, unsigned  long  )

virtual

Return 0 for success. 1 for error.

Selects for key up/down, button up/down, pointer motion, enter/leave, focus change, using core Xlib if ANXWIN_NO_INPUT is not set in win->win_style.

Reimplemented from Laxkit::LaxDevice.

References Laxkit::anXApp::app.

int Laxkit::CoreXlibPointer::setMouseShape ( anXWindow *  win, int  shape  )

virtual

Return 0 for success, nonzero for error.

Reimplemented from Laxkit::LaxMouse.

References Laxkit::anXApp::app.

int Laxkit::CoreXlibPointer::ungrabDevice ( )

virtual

Return 0 for success, 1 for failure.

Todo:

what on earth does XUngrabPointer() actually return??
