Gridbag Constraints Properties
Description of the gridbag constraints set of properties.
Syntax
constraints = createConstraints("gridbag") constraints = createConstraints("gridbag", grid) constraints = createConstraints("gridbag", grid, weight) constraints = createConstraints("gridbag", grid, weight, fill) constraints = createConstraints("gridbag", grid, weight, fill, anchor) constraints = createConstraints("gridbag", grid, weight, fill, anchor, padding) constraints = createConstraints("gridbag", grid, weight, fill, anchor, padding, preferredsize)
Arguments
- grid
[pos_x, pos_y, width, height]a 1-by-4 matrix of double, [0, 0, 0, 0] by default.pos_xandpos_xare the coordinates of the element on a virtual grid.widthandheightare the width and height of the element on the virtual grid.- weight
[weight_x, weight_y]a 1-by-2 matrix of doubles, [0, 0] by default.The weights applied for the resize on either axes.
A larger value means the element will get more space during resize.
- fill
A string
{"none"} | "horizontal" | "vertical" | "both"
Indicates how to fill the available space during resize on either direction (or both).
- anchor
A string
{"center"} | "upper" | "upper_right" | "right" | "lower_right" | "lower" | "lower_left" | "left" | "upper_left"
Tells where to anchor the element when it is smaller than the area it is nested in.
- padding
[pad_x, pad_y]a 1-by-2 matrix of doubles, [0 0] by defaultPadding between this element and elements around it.
- preferred_size
[p_size_x, p_size_y]a 1-by-2 matrix of doubles, [-1 -1] by defaultPreferred size in pixel when not constrained, used to avoid changing the size when resizing the nesting frame.
- constraints
The created constraints.
