Events

Change

The notification is called when the text property is changed, either interactively or as a result of direct call.

Properties

alignment INTEGER

One of the following ta:: constants, defining the text alignment:

        ta::Left
        ta::Right
        ta::Center

Default value: ta::Left

autoHeight BOOLEAN

If 1, adjusts the height of the widget automatically when its font changes.

Default value: 1

autoSelect BOOLEAN

If 1, all the text is selected when the widget becomes focused.

Default value: 1

autoTab BOOLEAN

If 1, the keyboard kb::Left and kb::Right commands, if received when the cursor is at the beginning or at the end of text, and cannot be mover farther, not processed. The result of this is that the default handler moves focus to a neighbor widget, in a way as if the Tab key was pressed.

Default value: 0

borderWidth INTEGER

Width of 3d-shade border around the widget.

Default value: 2

charOffset INTEGER

Selects the position of the cursor in characters starting from the beginning of text.

firstChar

Selects the first visible character of text

insertMode BOOLEAN

Governs the typing mode - if 1, the typed text is inserted, if 0, the text overwrites the old text. When insertMode is 0, the cursor shape is thick and covers the whole character; when 1, it is of default width.

Default toggle key: Insert

maxLen INTEGER

The maximal length of the text, that can be stored into text or typed by the user.

Default value: 256

Two integers, specifying the beginning and the end of the selected text. A case with no selection is when START equals END.

selStart INTEGER

Selects the start of text selection.

selEnd INTEGER

Selects the end of text selection.

textRef SCALAR_REF

If not undef, contains reference to the scalar that holds the text of the input line. All changes to ::text property are reflected there. The direct write access to the scalar is not recommended because it leaves internal structures inconsistent, and the only way to synchronize structures is to set-call either ::textRef or ::text after every such change.

If undef, the internal text container is used.

Default value: undef

wordDelimiters STRING

Contains string of character that are used for locating a word break. Default STRING value consists of punctuation marks, space and tab characters, and \xff character.
