Overview ¶
Package grid helps to build grid layouts.
Example ¶
Shows how to create a simple 4x4 grid with four widgets. All the cells in the grid contain the same widget in this example.
tbx, err := termbox.New()
if err != nil {
panic(err)
}
defer tbx.Close()
bc, err := barchart.New()
if err != nil {
panic(err)
}
builder := New()
builder.Add(
RowHeightPerc(
50,
ColWidthPerc(50, Widget(bc)),
ColWidthPerc(50, Widget(bc)),
),
RowHeightPerc(
50,
ColWidthPerc(50, Widget(bc)),
ColWidthPerc(50, Widget(bc)),
),
)
gridOpts, err := builder.Build()
if err != nil {
panic(err)
}
cont, err := container.New(tbx, gridOpts...)
if err != nil {
panic(err)
}
ctx, cancel := context.WithTimeout(context.Background(), 10*time.Second)
defer cancel()
if err := termdash.Run(ctx, tbx, cont); err != nil {
panic(err)
}
Example (Iterative) ¶
Shows how to create rows iteratively. Each row contains two columns and each column contains the same widget.
tbx, err := termbox.New()
if err != nil {
panic(err)
}
defer tbx.Close()
bc, err := barchart.New()
if err != nil {
panic(err)
}
builder := New()
for i := 0; i < 5; i++ {
builder.Add(
RowHeightPerc(
20,
ColWidthPerc(50, Widget(bc)),
ColWidthPerc(50, Widget(bc)),
),
)
}
gridOpts, err := builder.Build()
if err != nil {
panic(err)
}
cont, err := container.New(tbx, gridOpts...)
if err != nil {
panic(err)
}
ctx, cancel := context.WithTimeout(context.Background(), 10*time.Second)
defer cancel()
if err := termdash.Run(ctx, tbx, cont); err != nil {
panic(err)
}

Types ¶
type Builder ¶
type Builder struct {
// contains filtered or unexported fields
}
Builder builds grid layouts.
type Element ¶
type Element interface {
// contains filtered or unexported methods
}
Element is an element that can be added to the grid.
func ColWidthPerc ¶
ColWidthPerc creates a column of the specified width. The width is supplied as width percentage of the parent element. The sum of all widths at the same level cannot be larger than 100%. If it is less that 100%, the last element stretches to the edge of the screen. The subElements can be either a single Widget or any combination of Rows and Columns.
func RowHeightPerc ¶
RowHeightPerc creates a row of the specified height. The height is supplied as height percentage of the parent element. The sum of all heights at the same level cannot be larger than 100%. If it is less that 100%, the last element stretches to the edge of the screen. The subElements can be either a single Widget or any combination of Rows and Columns.
