Detailed Description

This is the FLTK text input widget.

It displays a single line of text and lets the user edit it. Normally it is drawn with an inset box and a white background. The text may contain any characters, and will correctly display any UTF text, using ^X notation for unprintable control characters. It assumes the font can draw any characters of the used scripts, which is true for standard fonts under Windows and Mac OS X. Characters can be input using the keyboard or the character palette/map. Character composition is done using dead keys and/or a compose key as defined by the operating system.

Keyboard and mouse bindings.

Mouse button 1	Moves the cursor to this point. Drag selects characters. Double click selects words. Triple click selects all line. Shift+click extends the selection. When you select text it is automatically copied to the selection buffer.
Mouse button 2	Insert the selection buffer at the point clicked. You can also select a region and replace it with the selection buffer by selecting the region with mouse button 2.
Mouse button 3	Currently acts like button 1.
Backspace	Deletes one character to the left, or deletes the selected region.
Delete	Deletes one character to the right, or deletes the selected region. Combine with Shift for equivalent of ^X (copy+cut).
Enter	May cause the callback, see when().

Platform specific keyboard bindings.

Windows/Linux	Mac	Function
^A	Command-A	Selects all text in the widget.
^C	Command-C	Copy the current selection to the clipboard.
^I	^I	Insert a tab.
^J	^J	Insert a Line Feed. (Similar to literal 'Enter' character)
^L	^L	Insert a Form Feed.
^M	^M	Insert a Carriage Return.
^V, Shift-Insert	Command-V	Paste the clipboard. (Macs keyboards don't have "Insert" keys, but if they did, Shift-Insert would work)
^X, Shift-Delete	Command-X, Shift-Delete	Cut. Copy the selection to the clipboard and delete it. (If there's no selection, Shift-Delete acts like Delete)
^Z	Command-Z	Undo. This is a single-level undo mechanism, but all adjacent deletions and insertions are concatenated into a single "undo". Often this will undo a lot more than you expected.
Shift-^Z	Shift-Command-Z	Redo. Currently same behavior as ^Z. Reserved for future multilevel undo/redo.
Arrow Keys	Arrow Keys	Standard cursor movement. Can be combined with Shift to extend selection.
Home	Command-Up, Command-Left	Move to start of line. Can be combined with Shift to extend selection.
End	Command-Down, Command-Right	Move to end of line. Can be combined with Shift to extend selection.
Ctrl-Home	Command-Up, Command-PgUp, Ctrl-Left	Move to top of document/field. In single line input, moves to start of line. In multiline input, moves to start of top line. Can be combined with Shift to extend selection.
Ctrl-End	Command-End, Command-PgDn, Ctrl-Right	Move to bottom of document/field. In single line input, moves to end of line. In multiline input, moves to end of last line. Can be combined with Shift to extend selection.
Ctrl-Left	Alt-Left	Word left. Can be combined with Shift to extend selection.
Ctrl-Right	Alt-Right	Word right. Can be combined with Shift to extend selection.
Ctrl-Backspace	Alt-Backspace	Delete word left.
Ctrl-Delete	Alt-Delete	Delete word right.

Constructor & Destructor Documentation

Fl_Input()

Fl_Input::Fl_Input	(	int	X,
		int	Y,
		int	W,
		int	H,
		const char *	l = 0
	)

Creates a new Fl_Input widget using the given position, size, and label string.

The default boxtype is FL_DOWN_BOX.

Member Function Documentation

draw()

void Fl_Input::draw ( )

protectedvirtual

Draws the widget.

Never call this function directly. FLTK will schedule redrawing whenever needed. If your widget must be redrawn as soon as possible, call redraw() instead.

Override this function to draw your own widgets.

If you ever need to call another widget's draw method from within your own draw() method, e.g. for an embedded scrollbar, you can do it (because draw() is virtual) like this:

Fl_Widget *s = &scrollbar; // scrollbar is an embedded Fl_Scrollbar
s->draw();                 // calls Fl_Scrollbar::draw()

Implements Fl_Widget.

handle()

int Fl_Input::handle ( int  event )

virtual

Handles the specified event.

You normally don't call this method directly, but instead let FLTK do it when the user interacts with the widget.

When implemented in a widget, this function must return 0 if the widget does not use the event or 1 otherwise.

Most of the time, you want to call the inherited handle() method in your overridden method so that you don't short-circuit events that you don't handle. In this last case you should return the callee retval.

One exception to the rule in the previous paragraph is if you really want to override the behavior of the base class. This requires knowledge of the details of the inherited class.

In rare cases you may want to return 1 from your handle() method although you don't really handle the event. The effect would be to filter event processing, for instance if you want to dismiss non-numeric characters (keypresses) in a numeric input widget. You may "ring the bell" or show another visual indication or drop the event silently. In such a case you must not call the handle() method of the base class and tell FLTK that you consumed the event by returning 1 even if you didn't do anything with it.

Parameters

[in]

event

the kind of event received

Return values

0	if the event was not used or understood
1	if the event was used and can be deleted

Fl_Event

Reimplemented from Fl_Widget.

Reimplemented in Fl_Spinner::Fl_Spinner_Input, and Fl_Secret_Input.

handle_key()

int Fl_Input::handle_key ( )

protected

Handles a keystroke.

This protected method handles a keystroke in an Fl_Input or derived class. It handles compose key sequences and can also be used e.g. in Fl_Multiline_Input, Fl_Float_Input and several more derived classes.

The method first checks in Fl::compose if the keystroke is a text entry or a control key. If it is text, the method inserts the composed characters into the input field, taking into account the input type (e.g., numeric fields).

If the keystroke is a control key as determined by Fl::compose, the method handles key combinations for Insert, Enter, and Tab depending on the widget's input_type().

The method then checks for Ctrl key combinations, such as Ctrl-A, Ctrl-C, Ctrl-V, Ctrl-X, and Ctrl-Z, which are commonly used for select all, copy, paste, cut, and undo operations.

Finally, the method checks for ASCII control characters, such as Ctrl-H, Ctrl-I, Ctrl-J, Ctrl-L, and Ctrl-M, which can be used to insert literal control characters into the input field.

If none of the above cases match, the method returns 0, indicating that the keystroke was not handled.

Returns

1 if the keystroke is handled by us, 0 if not.
