Functions

func ClearHighlightRange

func ClearHighlightRange(t *widget.TextGrid, blockMode bool, startRow, startCol, endRow, endCol int)

ClearHighlightRange disables the highlight style for the given range

func GetTextRange

func GetTextRange(t *widget.TextGrid, blockMode bool, startRow, startCol, endRow, endCol int) string

GetTextRange retrieves a text range from the TextGrid. It collects the text within the specified grid coordinates, starting from (startRow, startCol) and ending at (endRow, endCol), and returns it as a string. The behavior of the selection depends on the blockMode parameter. If blockMode is true, then startCol and endCol apply to each row in the range, creating a block selection. If blockMode is false, startCol applies only to the first row, and endCol applies only to the last row, resulting in a continuous range.

Parameters:

• blockMode: A boolean flag indicating whether to use block mode.
• startRow: The starting row index of the text range.
• startCol: The starting column index of the text range.
• endRow: The ending row index of the text range.
• endCol: The ending column index of the text range.

Returns:

• string: The text content within the specified range as a string.

func HighlightRange

func HighlightRange(t *widget.TextGrid, blockMode bool, startRow, startCol, endRow, endCol int, bitmask byte)

HighlightRange highlight options to the given range if highlighting has previously been applied it is enabled

func NewTermTextGridStyle

func NewTermTextGridStyle(fg, bg color.Color, bitmask byte) widget.TextGridStyle

NewTermTextGridStyle creates a new TextGridStyle with the specified foreground (fg) and background (bg) colors, as well as a bitmask to control the inversion of colors. If fg or bg is nil, the function will use default foreground and background colors from the theme. The bitmask is used to determine which color channels should be inverted.

Parameters:

• fg: The foreground color.
• bg: The background color.
• bitmask: The bitmask to control color inversion.

Returns:

A pointer to a TermTextGridStyle initialized with the provided colors and inversion settings.
