Detailed Description

the cgv namespace

Outline of the algorithm: Input parameters:

• width and height of the whole table
• elements with minimum, optimum and default width and height and resize properties
• c: Number of columns
• r: Number of rows

Method "update":

• Method "initialize_space_tables":
  • Create an array with c elements for all columns (one structure per column)
  • For every column do:
    • Get the maximum width of elements
    • Set hints for the column:
      • If one of the elements is expandable then the column is expandable
      • If one of the elements is shrinkable then the column is shrinkable

Do the same for all rows

• As long as the relayouting process is not finished:
  • Method "distribute_space":
    • Sum the space needed for all columns
      • If the space is smaller than the available space:
        • Expand elements that can be expanded or filled
      • If the space is bigger than the available space:
        • Shrink elements that can be shrunk
      • Do the same for all rows
  • For all elements (children) in the table at position (i,j):
    • Get width at columns[i] and height at rows[j]
      • Method "calculate_child_size":
        • If the child can expand in X then set its width to columns[i]
          • If the child cannot expand in X then set its width to its optimal width
          • ... same for Y
      • Try to apply the width and height for the child
      • Get the width and height of the child
      • If it could not set the width or height update the childs minimum width and height
      • If the overall width or height exceeds the available table dimensions:
        • Expand the table
          • Queue another relayout iteration with the new extents
• For all elements (children) in the table:
  • Method "calculate_child_pos":
    • If the child's X-alignment is middle then use the remaining cell space/2 as X offset
      • If the child's X-alignment is right then use the remaining cell space as X offset
      • ... same for Y
  • Set size and position
  • If the overall table size differs from the requested size:
    • Method "repair_default_values":
      • Set the new minimum and default width for the table

file use this header to include opengl, glu and glew in the right order. If you need wglew.h, include <cgv_gl/gl/wgl.h> instead.
