	Removes the floating endpoint from the Line Tool, creating an undo action to insert the endpoint.
Static Public Member Functions
static ActionCode	Init (Operation *pOp, ActionList *pActionList, BezierTool *pTool, Action **NewAction)
	This is the function which creates an instance of this action. If there is no room in the undo buffer (which is determined by the base class Init function called within) the function will either return AC_NO_RECORD which means the operation can continue, but no undo information needs to be stored, or AC_OK which means the operation should continue AND record undo information. If the function returns AC_FAIL, there was not enough memory to record the undo information, and the user has decided not to continue with the operation.
static ActionCode	DoRemove (Operation *pOp, ActionList *pActionList, BezierTool *pTool)
	This static function makes it a little easier to use this action. It creates an instance of this action and appends it to the action list.

ActionCode RemoveFloaterAction::DoRemove (  Operation *  pOp, ActionList *  pActionList, BezierTool *  pTool )  [static]

This static function makes it a little easier to use this action. It creates an instance of this action and appends it to the action list. Author: Peter_Arnold (Xara Group Ltd) <camelotdev@xara.com> Date: 05/12/94 Parameters: pOp  is the currently running operation [INPUTS] pActionList is a pointer ot the action list to which the action should be appended pTool is a pointer to the Line tool. -  [OUTPUTS] Returns: Action code which indicates success or failure to create the action Errors: - See also: InsertFloaterAction::DoInsert Definition at line 1350 of file opbezier.cpp. { RemoveFloaterAction* RecAction; ActionCode Act = RemoveFloaterAction::Init(pOp, pActionList, pTool, (Action**)&RecAction); return Act; }

ActionCode RemoveFloaterAction::Execute (   )  [virtual]

Removes the floating endpoint from the Line Tool, creating an undo action to insert the endpoint. Author: Peter_Arnold (Xara Group Ltd) <camelotdev@xara.com> Date: 05/12/94 Parameters: -  [INPUTS] -  [OUTPUTS] Returns: ActionCode, either AC_OK, AC_NORECORD or AC_FAIL Errors: - See also: InsertFloaterAction::Execute Reimplemented from Action.

ActionCode RemoveFloaterAction::Init (  Operation *  pOp, ActionList *  pActionList, BezierTool *  pTool, Action **  NewAction )  [static]

This is the function which creates an instance of this action. If there is no room in the undo buffer (which is determined by the base class Init function called within) the function will either return AC_NO_RECORD which means the operation can continue, but no undo information needs to be stored, or AC_OK which means the operation should continue AND record undo information. If the function returns AC_FAIL, there was not enough memory to record the undo information, and the user has decided not to continue with the operation. Author: Peter_Arnold (Xara Group Ltd) <camelotdev@xara.com> Date: 05/12/94 Parameters: pOp  is the pointer to the operation to which this action belongs [INPUTS] pTool is a pointer to the Line tool so the action can access the SetLineTo and ClearLineTo functions pActionList is the action list to which this action should be added NewAction  is a pointer to a pointer to an action, allowing the function to [OUTPUTS] return a pointer to the created action Returns: ActionCode, one of AC_OK, AC_NO_RECORD or AC_FAIL Errors: - See also: Action::Init() Definition at line 1313 of file opbezier.cpp. { UINT32 ActSize = sizeof(RemoveFloaterAction); ActionCode Ac = Action::Init( pOp, pActionList, ActSize, CC_RUNTIME_CLASS(RemoveFloaterAction), NewAction); if ((Ac == AC_OK) && (*NewAction != NULL)) { ((RemoveFloaterAction*)*NewAction)->pLineTool = pTool; } return Ac; }
