Property SelectedStart

Namespace

Assembly

Terminal.Gui.dll

SelectedStart

Gets or sets the anchor position where text selection began, measured as a 0-based index into text elements.

public int SelectedStart { get; set; }

Property Value

int

The starting position of the selection, or -1 if no selection is active. The value is clamped to the range [-1, Text.Length].

Remarks

Selection model: TextField uses an anchor-based selection model:

• SelectedStart: The anchor point where selection began (can be before or after insertion point)
• InsertionPoint: The current end of the selection
• SelectedLength: The absolute length of the selection

Example: In text "Hello World", selecting "World" by shift+clicking:

• If insertion point was at position 6 and user shift-clicks at position 11: SelectedStart=6, InsertionPoint=11
• If insertion point was at position 11 and user shift-clicks at position 6: SelectedStart=11, InsertionPoint=6
• In both cases, SelectedLength=5 and SelectedText="World"

Setting this property triggers PrepareSelection(int, int) to update the selection state.
