| MSWindows only.
After having opened an Fl_Native_File_Chooser with a
ctrl-O shortcut, and closed it, the ctrl modifier
is seen as still present by FLTK, until the keyboard is used again.
For example, click is interpreted as ctrl-click until the keyboard
is used.
Use the attached test program to see the bug:
- click to see Fl::event_ctrl()=0
- press the ctrl key and click to see Fl::event_ctrl()=262144
- press ctrl-O. It opens a Fl_Native_File_Chooser window
- close it without using the keyboard (e.g., click on cancel)
- click to see Fl::event_ctrl()=262144
even though the ctrl key is no longer pressed: THIS IS THE BUG
- press any key
- click to see Fl::event_ctrl()=0 as expected
The attached fnfc.patch is proposed to fix the bug. | |

| Ignore fnfc.patch, and use fnfc2.patch instead. | |

| Same problem when opening a print dialog window with
ctrl-P: if the dialog is closed without using the keyboard
the ctrl modifier appears ON to FLTK when back to
an FLTK window.
Thus a proper fix can't be specific to Fl_Native_File_Chooser.
It seems that the ctrl key up event is not seen by FLTK
in this scenario:
- press ctrl-O (or ctrl-P)
- this triggers opening of a non FLTK, native window
- release keyboard keys
- close the native window without using the keyboard
- click in an FLTK window ==> FLTK sees ctrl-click | |
