Function Documentation

int dmxCheckSpecialKeys (  DevicePtr  pDev, KeySym  keySym )

A pointer to this routine is passed to low-level input drivers so that all special keychecking is unified to this file. This function returns 0 if no special keys have been pressed. If the user has requested termination of the DMX server, -1 is returned. If the user has requested a switch to a VT, then the (1-based) number of that VT is returned.

void dmxEnqueue (  DevicePtr  pDev, int  type, int  detail, KeySym  keySym, XEvent *  e, DMXBlockType  block )

Enqueue a non-motion event from the pDev device with the specified type and detail. If the event is a KeyPress or KeyRelease event, then the keySym is also specified. If block is set to DMX_BLOCK, then the SIGIO handler will be blocked around calls to dmxeqEnqueue().

void dmxGetGlobalPosition (  int *  x, int *  y )

Return DMX's notion of the pointer position in the global coordinate space.

void dmxInvalidateGlobalPosition (  void   )

Invalidate the global position for #dmxCoreMotion.

void dmxMotion (  DevicePtr  pDev, int *  v, int  firstAxes, int  axesCount, DMXMotionType  type, DMXBlockType  block )

Enqueue a motion event for pDev. The v vector has length axesCount, and contains values for each of the axes, starting at firstAxes. The type of the motion may be DMX_RELATIVE, DMX_ABSOLUTE, or DMX_ABSOLUTE_CONFINED (in the latter case, the pointer will not be allowed to move outside the global boundaires). If block is set to DMX_BLOCK, then the SIGIO handler will be blocked around calls to dmxeqEnqueue().
