Layout abstraction and default layout #38

Closed voytech closed 6 years ago

voytech commented 6 years ago

Implement layout abstraction to allow different approaches to position elements. Same layouting mechanisms should be used for different containers :

for attribute container ( entity )
for entity container (project canvas, root entities)
for component layer ? ( construct not yet exists - just thinking of it )

Common properties of layouts :

layout name
layouting function
layout instance properties:
- origin(x,y) - starting point of transforms relative to container. Origin can be : center , corner.
- left or right - relative position from origin (pixels or percents)
- top or bottom - relative position from origin (pixels or percents)
- width, height (pixels or percents - if percents then its relative to container sizing.
- direction - left-to-right, right-to-left, top-to-bottom, bottom-to-top.
- overflow - extend, hide.

Layout properties should include just a layouting function plus options which can be specific for that function . They can include origin, left, right and so on
