| - | **Remarks** | ||
| - | |||
| - | The collision area (the pointer image restricted area) is established by [[open|MouOpen]] and by [[removeptr|MouRemovePtr]]. [[drawptr|MouDrawPtr]] nullifies the effect of the [[removeptr|MouRemovePtr]] command. If there was no previous [[drawptr|MouDrawPtr]] command or if a previous [[drawptr|MouDrawPtr]] command has already nullified the collision area, the [[removeptr|MouRemovePtr]] command is effectively a null operation. | ||
| - | |||
| - | This call is required to begin session pointer image drawing. Immediately after [[open|MouOpen]] is issued, the collision area is defined as the size of the display. A [[drawptr|MouDrawPtr]] is issued to begin pointer drawing after the [[open|MouOpen]]. | ||
