Version Numbers

FLTK defines some constants to help the programmer to find out, for which FLTK version a program is compiled.

The following constants are defined:

#define FL_MAJOR_VERSION   1
 
#define FL_MINOR_VERSION   3
 
#define FL_PATCH_VERSION   5
 
#define FL_VERSION
 
#define FL_API_VERSION   (FL_MAJOR_VERSION*10000 + FL_MINOR_VERSION*100 + FL_PATCH_VERSION)
 
#define FL_ABI_VERSION   (FL_MAJOR_VERSION*10000 + FL_MINOR_VERSION*100)
 
#define FLTK_ABI_VERSION   FL_ABI_VERSION
 
Mouse and Keyboard Events

This and the following constants define the non-ASCII keys on the keyboard for FL_KEYBOARD and FL_SHORTCUT events.

Todo:
FL_Button and FL_key... constants could be structured better (use an enum or some doxygen grouping ?)

Box Types

FLTK standard box types

This enum defines the standard box types included with FLTK.

FL_NO_BOX means nothing is drawn at all, so whatever is already on the screen remains. The FL_..._FRAME types only draw their edges, leaving the interior unchanged. The blue color in Figure 1 is the area that is not drawn by the frame types.

Alignment Flags

Flags to control the label alignment.

This controls how the label is displayed next to or inside the widget. The default value is FL_ALIGN_CENTER (0) for most widgets, which centers the label inside the widget.

Flags can be or'd to achieve a combination of alignments, but there are some "magic values" (e.g. combinations of TOP and BOTTOM and of LEFT and RIGHT) that have special meanings (see below). For instance:
FL_ALIGN_TOP_LEFT == (FL_ALIGN_TOP|FL_ALIGN_LEFT) != FL_ALIGN_LEFT_TOP.

Outside alignments (FL_ALIGN_INSIDE is not set):
TOP_LEFT TOP TOP_RIGHT
+---------------------------------+
LEFT_TOP| |RIGHT_TOP
| |
LEFT| CENTER |RIGHT
| |
LEFT_BOTTOM| |RIGHT_BOTTOM
+---------------------------------+
BOTTOM_LEFT BOTTOM BOTTOM_RIGHT
Inside alignments (FL_ALIGN_INSIDE is set):
+---------------------------------+
|TOP_LEFT TOP TOP_RIGHT|
| |
|LEFT CENTER RIGHT|
| |
|BOTTOM_LEFT BOTTOM BOTTOM_RIGHT|
+---------------------------------+

Colors

The Fl_Color type holds an FLTK color value.

Colors are either 8-bit indexes into a virtual colormap or 24-bit RGB color values. (See Colors for the default FLTK colormap)

Color indices occupy the lower 8 bits of the value, while RGB colors occupy the upper 24 bits, for a byte organization of RGBI.

 Fl_Color => 0xrrggbbii
                | | | |
                | | | +--- index between 0 and 255
                | | +----- blue color component (8 bit)

◆ FL_ABI_VERSION

#define FL_ABI_VERSION   (FL_MAJOR_VERSION*10000 + FL_MINOR_VERSION*100)

The FLTK ABI (Application Binary Interface) version number as an int.

FL_ABI_VERSION is an int that describes the major, minor, and patch ABI version numbers in the same format as FL_API_VERSION.

The ABI version number FL_ABI_VERSION is usually the same as the API version FL_API_VERSION with the last two digits set to '00'.

FLTK retains the ABI (Application Binary Interface) during patch releases of the same major and minor versions. Examples:

  FLTK Version  FL_API_VERSION  FL_ABI_VERSION  FL_VERSION (deprecated)
    1.3.0          10300           10300           1.0300
1.3.4          10304           10300           1.0304

Version 1.2.3 is actually stored as 10203 to allow for more than 9 minor and patch releases.

The FL_MAJOR_VERSION, FL_MINOR_VERSION, and FL_PATCH_VERSION constants give the integral values for the major, minor, and patch releases respectively.

To enable new ABI-breaking features in patch releases you can configure FLTK to use a higher FL_ABI_VERSION.

◆ FL_API_VERSION

#define FL_API_VERSION   (FL_MAJOR_VERSION*10000 + FL_MINOR_VERSION*100 + FL_PATCH_VERSION)

The FLTK API version number as an int.

FL_API_VERSION is an int that describes the major, minor, and patch version numbers.

Version 1.2.3 is actually stored as 10203 to allow for more than 9 minor and patch releases.

The FL_MAJOR_VERSION, FL_MINOR_VERSION, and FL_PATCH_VERSION constants give the integral values for the major, minor, and patch releases respectively.

Note
FL_API_VERSION is intended to replace the deprecated double FL_VERSION.

#define FL_VERSION
Value:
( (double)FL_MAJOR_VERSION + \
(double)FL_MINOR_VERSION * 0.01 + \
(double)FL_PATCH_VERSION * 0.0001 )

The FLTK version number as a double.

FL_VERSION is a double that describes the major, minor, and patch version numbers.

Version 1.2.3 is actually stored as 1.0203 to allow for more than 9 minor and patch releases.

Deprecated:
This double version number is retained for compatibility with existing program code. New code should use int FL_API_VERSION instead. FL_VERSION is deprecated because comparisons of floating point values may fail due to rounding errors. However, there are currently no plans to remove this deprecated constant.

FL_VERSION is equivalent to (double)FL_API_VERSION / 10000.

◆ Fl_Event

enum Fl_Event

Every time a user moves the mouse pointer, clicks a button, or presses a key, an event is generated and sent to your application. Events can also come from other programs like the window manager.

Events are identified by the integer argument passed to the Fl_Widget::handle() virtual method. Other information about the most recent event is stored in static locations and acquired by calling the Fl::event_*() methods. This static information remains valid until the next event is read from the window system, so it is ok to look at it outside of the handle() method.

Event numbers can be converted to their actual names using the fl_eventnames[] array defined in #include <FL/names.h>

See also
Fl::event_text(), Fl::event_key(), class Fl::
Enumerator
FL_NO_EVENT 

No event.

FL_PUSH 

A mouse button has gone down with the mouse pointing at this widget. You can find out what button by calling Fl::event_button(). You find out the mouse position by calling Fl::event_x() and Fl::event_y().

A widget indicates that it "wants" the mouse click by returning non-zero from its Fl_Widget::handle() method. It will then become the Fl::pushed() widget and will get FL_DRAG and the matching FL_RELEASE events.
If Fl_Widget::handle() returns zero then FLTK will try sending the FL_PUSH to another widget.

FL_RELEASE 

A mouse button has been released. You can find out what button by calling Fl::event_button().

In order to receive the FL_RELEASE event, the widget must return non-zero when handling FL_PUSH.

FL_ENTER 

The mouse has been moved to point at this widget. This can be used for highlighting feedback. If a widget wants to highlight or otherwise track the mouse, it indicates this by returning non-zero from its handle() method. It then becomes the Fl::belowmouse() widget and will receive FL_MOVE and FL_LEAVE events.

FL_LEAVE 

The mouse has moved out of the widget. In order to receive the FL_LEAVE event, the widget must return non-zero when handling FL_ENTER.

FL_DRAG 

The mouse has moved with a button held down. The current button state is in Fl::event_state(). The mouse position is in Fl::event_x() and Fl::event_y().

In order to receive FL_DRAG events, the widget must return non-zero when handling FL_PUSH.

FL_FOCUS 

This indicates an attempt to give a widget the keyboard focus.

If a widget wants the focus, it should change itself to display the fact that it has the focus, and return non-zero from its handle() method. It then becomes the Fl::focus() widget and gets FL_KEYDOWN, FL_KEYUP, and FL_UNFOCUS events.

The focus will change either because the window manager changed which window gets the focus, or because the user tried to navigate using tab, arrows, or other keys. You can check Fl::event_key() to figure out why it moved. For navigation it will be the key pressed and for interaction with the window manager it will be zero.

FL_UNFOCUS 

This event is sent to the previous Fl::focus() widget when another widget gets the focus or the window loses focus.

FL_KEYDOWN 

A key was pressed (FL_KEYDOWN) or released (FL_KEYUP). Fl_KEYBOARD is a synonym for FL_KEYDOWN. The key can be found in Fl::event_key(). The text that the key should insert can be found with Fl::event_text() and its length is in Fl::event_length(). If you use the key handle() should return 1. If you return zero then FLTK assumes you ignored the key and will then attempt to send it to a parent widget. If none of them want it, it will change the event into a FL_SHORTCUT event.

To receive FL_KEYBOARD events you must also respond to the FL_FOCUS and FL_UNFOCUS events.

If you are writing a text-editing widget you may also want to call the Fl::compose() function to translate individual keystrokes into non-ASCII characters.

FL_KEYUP events are sent to the widget that currently has focus. This is not necessarily the same widget that received the corresponding FL_KEYDOWN event because focus may have changed between events.

FL_KEYBOARD 

Equivalent to FL_KEYDOWN.

See also
FL_KEYDOWN
FL_KEYUP 

Key release event.

See also
FL_KEYDOWN
FL_CLOSE 

The user clicked the close button of a window. This event is used internally only to trigger the callback of Fl_Window derived classed. The default callback closes the window calling Fl_Window::hide().

FL_MOVE 

The mouse has moved without any mouse buttons held down. This event is sent to the Fl::belowmouse() widget.

In order to receive FL_MOVE events, the widget must return non-zero when handling FL_ENTER.

FL_SHORTCUT 

If the Fl::focus() widget is zero or ignores an FL_KEYBOARD event then FLTK tries sending this event to every widget it can, until one of them returns non-zero. FL_SHORTCUT is first sent to the Fl::belowmouse() widget, then its parents and siblings, and eventually to every widget in the window, trying to find an object that returns non-zero. FLTK tries really hard to not to ignore any keystrokes!

You can also make "global" shortcuts by using Fl::add_handler(). A global shortcut will work no matter what windows are displayed or which one has the focus.

FL_DEACTIVATE 

This widget is no longer active, due to Fl_Widget::deactivate() being called on it or one of its parents. Fl_Widget::active() may still be true after this, the widget is only active if Fl_Widget::active() is true on it and all its parents (use Fl_Widget::active_r() to check this).

FL_ACTIVATE 

This widget is now active, due to Fl_Widget::activate() being called on it or one of its parents.

FL_HIDE 

This widget is no longer visible, due to Fl_Widget::hide() being called on it or one of its parents, or due to a parent window being minimized. Fl_Widget::visible() may still be true after this, but the widget is visible only if visible() is true for it and all its parents (use Fl_Widget::visible_r() to check this).

FL_SHOW 

This widget is visible again, due to Fl_Widget::show() being called on it or one of its parents, or due to a parent window being restored. Child Fl_Windows respond to this by actually creating the window if not done already, so if you subclass a window, be sure to pass FL_SHOW to the base class Fl_Widget::handle() method!

FL_PASTE 

You should get this event some time after you call Fl::paste(). The contents of Fl::event_text() is the text to insert and the number of characters is in Fl::event_length().

FL_SELECTIONCLEAR 

The Fl::selection_owner() will get this event before the selection is moved to another widget. This indicates that some other widget or program has claimed the selection. Motif programs used this to clear the selection indication. Most modern programs ignore this.

FL_MOUSEWHEEL 

The user has moved the mouse wheel. The Fl::event_dx() and Fl::event_dy() methods can be used to find the amount to scroll horizontally and vertically.

FL_DND_ENTER 

The mouse has been moved to point at this widget. A widget that is interested in receiving drag'n'drop data must return 1 to receive FL_DND_DRAG, FL_DND_LEAVE and FL_DND_RELEASE events.

FL_DND_DRAG 

The mouse has been moved inside a widget while dragging data. A widget that is interested in receiving drag'n'drop data should indicate the possible drop position.

FL_DND_LEAVE 

The mouse has moved out of the widget.

FL_DND_RELEASE 

The user has released the mouse button dropping data into the widget. If the widget returns 1, it will receive the data in the immediately following FL_PASTE event.

FL_SCREEN_CONFIGURATION_CHANGED 

The screen configuration (number, positions) was changed. Use Fl::add_handler() to be notified of this event.

FL_FULLSCREEN 

The fullscreen state of the window has changed

FL_ZOOM_GESTURE 

The user has made a zoom/pinch/magnification gesture. The Fl::event_dy() method can be used to find magnification amount, Fl::event_x() and Fl::event_y() are set as well.
