Detailed Description

Implementation of the member functions of class Fl.

Function Documentation

fl_close_display()

void fl_close_display

(

)

Closes the connection to the windowing system when that's possible.

You do not need to call this to exit, and in fact it is faster to not do so. It may be useful to call this if you want your program to continue without a GUI. You cannot open the display again, and cannot call any FLTK functions.

Note

Requires #include <FL/platform.H>

fl_find()

Fl_Window * fl_find

(

Window

xid

)

Returns the Fl_Window that corresponds to the given window reference, or NULL if not found.

Deprecated:

Kept in the X11, Windows, and macOS platforms for compatibility with FLTK versions before 1.4. Please use fl_x11_find(Window), fl_wl_find(struct wld_window*), fl_win32_find(HWND) or fl_mac_find(FLWindow*) with FLTK 1.4.0 and above.

fl_open_display()

void fl_open_display

(

)

Opens the display.

Automatically called by the library when the first window is show()'n. Does nothing if the display is already open.

Note

Requires #include <FL/platform.H>

Variable Documentation

fl_disable_wayland

bool fl_disable_wayland = true

Prevent the FLTK library from using its Wayland backend and forces it to use its X11 backend.

Put this declaration somewhere in your code outside the body of any function :

FL_EXPORT bool fl_disable_wayland = true;

This declaration makes sure source code developed for FLTK 1.3, including X11-specific code, will build and run with FLTK 1.4 and its Wayland platform with this single source code level change. This declaration has no effect on non-Wayland platforms. Don't put this declaration if you want the Wayland backend to be used when it's available.
