Struct zng_wgt_text_input::TextInput

pub struct TextInput(/* private fields */);

W Simple text editor widget.

If txt is set to a variable that can be modified the widget becomes interactive, it implements the usual text box capabilities: keyboard editing of text in a single style, pointer caret positioning and text selection.

You can also use text::cmd to edit the text.

Undo/Redo

Undo/redo is enabled by default, the widget is an undo scope and handles undo commands. Note that external changes to the txt variable clears the undo stack, only changes done by the widget can be undone.

Shorthand

The TextInput! macro provides shorthand syntax that sets the txt property.

let editable_text = TextInput!(var_from(""));
