Analysis

Overview

Frame position can be now set by changing values in a HUD or by dragging the frame move halo. The frame move halo should be replaced with a frame title bar which is draggable and moves the frame around.

• The title bar should be at the top of the frame
• Height - the title bar height is equal to halo height + title bar padding. Title bar height doesn't need to be recalculated
• Width - the title bar should contain all needed halos + frame (group) title. This means that minimum witdth is equal to number of halos + space between them + title bar padding + frame name. For selections, the title bar should not be shorter than halos + space between them + padding + amount of pixels (for example - 10)
• Color - the title bar should be semi transparent and should allow changing opacity (and color) on mouse over and mouse pressed.

Task requirements

Create the frame title bar

• This is generally a draggable halo that stays behind the other halos
• Cover the functionalities from the overview
  • Height
  • Width
  • Color
• The position of the title bar depends on upper halo menu position - title bar is behind other halos.
• When the frame is small, the halos should appear the following way:
  

• Introduce another rectangle, relative to the minimal size needed for the title bar.
• Optional - include frame (group) name in the frame title bar. Selections do not need to have titles.

How to demo

• Insert a frame
• Move the frame
• Make the frame tiny (1x1px)
• Move the frame again
• Deselect the frame

Design

• Remove FrameMoveHaloMenu class.
  • Make MainHaloMenu a parent of FrameRemoveHaloButton.
• FrameMoveHaloButton is replaced by a new class MainTitleBar extending AbstractHalo having the following functionalities.
  • Mouse click and movement handling from FrameMoveHaloButton.
  • Override parent(), computeTitle(), computeSize() and computeVisible() methods.
  • The MainHaloMenu is the parent
  • The size of the title bar is calculated as specified
    • The height is equal to the biggest height of all halo buttons + padding
    • The width is the maximal value between the width of the frame and the cumulative width of the halos + side padding + halo spacing + frame (group) name length calculated with default font.
• HaloMenu class is changed.
  • locationSync() method modified to consider right alignment of buttons on the menu (needed for FrameRemoveHaloButton).
  • HaloMenu.computeSize() protected method added.
• HaloButton.alignPos() added to specify the needed alignment of the halo button on its parent.
• Modify FrameRotateHaloMenu.computeLocation() to move rotate halo menu to the bottom right point of the frame.
• Testing
  • Existing unit tests in ​org.sophie2.base.halos.
  • Demo test
    • Start ​HalosDemo.
    • Select a frame
      • There should be no frame move menu.
      • There should be no move frame halo button.
      • The remove frame halo button should be right aligned.
    • Frame movement should be possible when dragging the title bar.
