Add argument 'center' to position the message box centered over the given x/y coordinates. Add another method to supply a widget or window to center the message box over. Fix documentation and don't use INT_MIN to avoid having to include limits.h in user code.

This timer callback shows a message dialog (fl_choice) window

every 5 seconds to test "recursive" common dialogs.
|
|
|
|
The timer can be stopped by clicking the button "Stop these funny popups"
|
|
or pressing the Enter key. As it is currently implemented, clicking the
|
|
"Close" button will reactivate the popups (only possible if "recursive"
|
|
dialogs are enabled, see below).
|
|
|
|
Note 1: This dialog box is blocked in FLTK 1.3.x if another common dialog
|
|
is already open because the window used is a static (i.e. permanently
|
|
allocated) Fl_Window instance. This should be fixed in FLTK 1.4.0.
|
|
See STR #334 (sic !) and also STR #2751 ("Limit input field characters").
