I made a one line fix to the component source so that the mouse cursors appear without handling OnMouseMove in the project. Debugging a OnMouseMove event is difficult so there may be a better way to achieve this, but the fix seems to work. All I had to do is add an exit in the OnMouseMove event so the cursor code is executed and not overwritten by code following the exit. The exit is shown in boldface:
procedure TImageEnView.MouseMove(Shift: TShiftState; X, Y: Integer);
procedure _MoveSelLayers(iMoveX, iMoveY: Integer);
var
aLayer: TIELayer;
i: Integer;
begin
if ( iMoveX = 0 ) and ( iMoveY = 0 ) then
exit;
for i := 0 to LayersCount - 1 do
begin
// Moving aLayer
aLayer := TIELayer( fLayers[ I ]);
if ( aLayer.Locked = False ) and aLayer.Selected then
begin
aLayer.PosX := aLayer.PosX - iMoveX;
aLayer.PosY := aLayer.PosY - iMoveY;
end;
end;
end;
procedure _RotateSelLayers(Value: Double; bSnapToStep: Boolean);
var
aLayer: TIELayer;
i: Integer;
begin
for i := 0 to LayersCount - 1 do
begin
// Rotating aLayer
aLayer := TIELayer( fLayers[ I ]);
if ( aLayer.Locked = False ) and ( aLayer.Selected or ( i = fRotatingLayer )) then
begin
if bSnapToStep then
aLayer.Rotate := trunc( Value / fLayersRotateStep ) * fLayersRotateStep
else
aLayer.Rotate := Value;
end;
end;
end;
