GGUserInputImpl: CEDAR PROGRAM

IMPORTS Atom, BiScrollers, Convert, GGError, GGObjects, GGSessionLog, SlackProcess, GGEvent, GGMouseEvent, IO, Rope, ViewerTools

EXPORTS GGUserInput = BEGIN

GargoyleData: TYPE = GGInterfaceTypes.GargoyleData;

Outline: TYPE = GGModelTypes.Outline;

Point: TYPE = GGBasicTypes.Point;

Viewer: TYPE = ViewerClasses.Viewer;

SlackHandle: TYPE = SlackProcess.SlackHandle;

EventProc: TYPE = SlackProcess.EventProc;

Input from the Outside World

From Buttons and Menus

MenuNotify: PUBLIC PROC [clientData: REF ANY, action: LIST OF REF ANY] = {

Used by several menu classes as the procedure to call when a menu click occurs.

gargoyleData: GargoyleData ← NARROW[clientData];

HandleMouseless[action, gargoyleData];

};

From Playback Scripts

PlayAction: PUBLIC PROC [point: Point, action: LIST OF REF ANY, mouseEvent: BOOL, gargoyleData: GargoyleData] = {

IF mouseEvent THEN HandleMouse[point, action, gargoyleData]

ELSE HandleMouseless[action, gargoyleData];

};

From Mouse and Keyboard

InputNotify: PUBLIC PROC [self: ViewerClasses.Viewer, input: LIST OF REF ANY] = {

ViewerClasses.NotifyProc

Called by the TIP table machinery when an action is received from mouse or keyboard. Self is an ActionArea.

gargoyleData: GargoyleData ← NARROW[BiScrollers.ClientDataOfViewer[self]];

IF printAllInput THEN PrintAllInput[input, gargoyleData];

WITH input.first SELECT FROM

mousePlace: BiScrollers.ClientCoords => {

controlPoint: Point ← [mousePlace.x, mousePlace.y];

This puts the control point in Gargoyle coordinates.

HandleMouse[controlPoint, input.rest, gargoyleData];

};

refChar: REF CHAR => {

Need our own copy of the ref and char, because the system will reuse the storage without telling us!!

myRefChar: REF CHAR ← NEW[CHAR ← refChar^];

HandleMouseless[LIST[$AddChar, myRefChar], gargoyleData];

};

ENDCASE => HandleMouseless[input, gargoyleData];

};

Handling Actions

From the Mouse

HandleMouse: PROC [controlPoint: Point, input: LIST OF REF ANY, gargoyleData: GargoyleData] = {

atom: ATOM ← NARROW[input.first];

atomName: Rope.ROPE ← Atom.GetPName[atom];

IF Rope.Equal[Rope.Substr[atomName, 0, 5], "Start", TRUE] THEN {

SlackProcess.QueueInputActionWithPoint[gargoyleData.slackHandle, GGMouseEvent.HandleMouse, input, controlPoint, gargoyleData, NIL];

SlackProcess.QueueInputAction[gargoyleData.slackHandle, GGEvent.SawTextFinish, LIST[$SawTextFinish], gargoyleData, NIL];

}

ELSE SELECT atom FROM

$GuardUp, $MouseUp, $AllUp => SlackProcess.QueueInputActionWithPoint[gargoyleData.slackHandle, GGMouseEvent.HandleMouse, input, controlPoint, gargoyleData, NIL];

$During => SlackProcess.QueueInputActionWithPoint[gargoyleData.slackHandle, GGMouseEvent.HandleMouse, input, controlPoint, gargoyleData, LIST[$During]];

ENDCASE => NotYetImplementedMessage[atom, gargoyleData];

};
