| | 60 | * Removing the rotate right and rotate left buttons from FrameRotateHaloMenu |
| | 61 | * Fixing the rotation properties dialog to rotate properly |
| | 62 | * Positioning the rotation halo menu properly |
| | 63 | * Writing a new class to handle both showing the rotation properties hud, and have it be draggable to rotate the frame |
| 72 | | FrameRotateHaloMenu currently defines it's location as the topRIght of the selection bounds, but that is no longer valid. Determine new location based on bottomRight, extended down the vector from the top left by a distance of 15 (constant defined in class HALO_OUTSET) and then rotating the center point of the hud around the content location point. |

| | 69 | * FrameRotateRightHaloButton (Removed from the menu, but fixed to ensure it would work should it be used at a later point in time) |
| | 70 | * FrameRotateLeftHaloButton (Removed from the menu, but fixed to ensure it would work should it be used at a later point in time) |

| | 77 | The follow classes were added: |
| 90 | | [[Image(FRAME_ROTATION_R1_UML.png)]] |
| | 96 | == FrameRotateLogic == |
| | 97 | |
| | 98 | This class now implements ROTATE_TO. This method has to back out the existing rotation before it can apply the new rotation, or the frame will "walk" across the page, because all frame rotation is based around the content location now. |
| | 99 | |
| | 100 | == AppHaloUtil == |
| | 101 | |
| | 102 | A helper method, getFirstFrameView, was added to get the first frame in the selection |
| | 103 | |
| | 104 | = FrameRotateHaloMenu = |
| | 105 | |
| | 106 | The computeLocation method was changed to a fairly complex bit of code. First, we have to calculate a line from the top left of the frame to the bottom right. We then extend this line by HALO_OFFSET, a static final value, to determine where the halo menu should be centered. We then calculate the new endpoint of the line and have a haloMenuCenter. |
| | 107 | |
| | 108 | This new center is in unrotated frame coodinates though, so we create a matrix rotated around the frame's content location to find the frameRotationCenter. |
| | 109 | |
| | 110 | Next we create a matrix to rotate a point around the frameRotationCenter by the frame's current rotation value, and transform our haloMenuCenter. |
| | 111 | |
| | 112 | Next, we use scene helpers to get the scene's effective transform and transform our haloMenuCenter by that. This is done so we zoom properly. |
| | 113 | |
| | 114 | Next, we offset the haloMenuCenter so the halo menu will be centered on the proper point. |
| | 115 | |
| | 116 | Finally, we convert the coordinates from scene to swing coordinates. The halo menu is now properly positioned for a rotated and scaled frame. |
| | 117 | |
| | 118 | == FrameDragRotatePropertiesHaloButton == |
| | 119 | |
| | 120 | FrameDragRotatePropertiesHaloButton is the class that handles showing the properties hud and rotating the frame when drug around the rotation center. It was discovered that the existing classes, MoveHaloButton and HaloHudButton were not designed to be used together. After some discussion, it was decided, in order to finish the task on time, to create FrameDragRotatePropertiesHaloButton and have it subclass from MoveHaloButton. |
| | 121 | |
| | 122 | Then, the two methods from HaloHudButton, hud() and computeHud() would be copied into this class, to save time until we refactor the other halo buttons. This allows FrameDragRotatePropertiesHaloButton to both show the properties hud when single clicked, and to rotate the frame when drug. |
| | 123 | |
| | 124 | However, the properties hud would not show, because HaloMenu checks for (b instanceOf HudHaloButton) in two places. Not wanting to break anything, but also finish the task, a new interface was implemented, HudHalo, with the single method hud(). |
| | 125 | |
| | 126 | Both HudHaloButton and FrameDragRotatePropertiesHaloButton implement HudHalo, and HaloMenu now checks (b instanceof HudHalo) for its sanity checks. This factors out the implemention from the intention of the class check. |
| | 127 | |
| | 128 | FrameDragRotatePropertiesHaloButton uses the same pattern as FrameMoveHaloButton. It calculates out the angle between the rotationCenter, the click point and the current mouse point. It then uses this to create a theta delta which is then applied to the frame via the ROTATE_BY EventR3. |
| | 129 | |
| | 130 | |
| | 131 | == MouseCapture == |
| | 132 | |
| | 133 | MouseCapture was updated slightly to record the original click location and the current click location. A new method, hasMoved(), was added that returns TRUE if the mouse has moved at all during the life of this MouseCapture instance, and false if it has not. |
