Types

type Box 

type Box struct {
	Kids       []*duit.Kid // Kids and UIs in this box.
	Reverse    bool        // Lay out children from bottom to top. First kid will be at the bottom.
	Margin     duit.Space  // In lowDPI pixels, will be adjusted for highDPI screens.
	Padding    duit.Space  // Padding inside box, so children don't touch the sides; in lowDPI pixels, also adjusted for highDPI screens.
	Valign     duit.Valign // How to align children on a line.
	Width      int         // 0 means dynamic (as much as needed), -1 means full width, >0 means that exact amount of lowDPI pixels.
	Height     int         // 0 means dynamic (as much as needed), -1 means full height, >0 means that exact amount of lowDPI pixels.
	MaxWidth   int         // if >0, the max number of lowDPI pixels that will be used.
	ContentBox bool        // Use ContentBox (BorderBox by default)
	Disp       Display
	Dir        Dir
	Background *draw.Image `json:"-"` // Background for this box, instead of default duit background.
	// contains filtered or unexported fields
}

Box keeps elements on a line as long as they fit, then moves on to the next line.
