input line text data is contained in text property.
API
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
passwordChar CHARACTER
A character to be shown instead of the text letters when writeOnly property value is 1.
Default value: '*'
readOnly BOOLEAN
If 1, the text cannot be edited by the user.
Default value: 0
selection START, END
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.
writeOnly BOOLEAN
If 1, the input is not shown but mapped to passwordChar characters. Useful for a password entry.
Default value: 0
