Analysis
Overview
The frame bounds are the frame size, position and Z order. There are 5 modes in which frame`s bounds could be calculated - Margins mode, Out-Border mode, Mid-Border mode, Padding mode (which is the same as In-Border mode) and Context mode. See trunk/sophie2-platform/doc/spec-diagrams/FrameBounds.png. Those modes determine the rectangular all coordinates are related to. The default mode is the Content mode. There are also 9 special points that could be observed when calculating frame coordinates - TOP_LEFT, TOP_MIDDLE, TOP_RIGHT, MIDDLE_LEFT, MIDDLE, MIDDLE_RIGHT,BOTTOM_LEFT, BOTTOM_MIDDLE, BOTTOM_RIGHT. The default one is the TOP_LEFT. For example in Padding mode and for TOP_RIGHT special point, the frames position is the position of the upper right point of the padding rectangular and the frame size is calculated including the paddings.
Task requirements
- There should be representation of those modes and points.
- (Optional, if there is time) There should be a communal hud for setting the frame bounds.
- There should be options for setting and getting the bounds in all modes and relating to all special points.
Task result
The result of this task is source code.
Implementation idea
- Create needed enums representing the needed modes and points.
