: i am reading microwindows' nanox API's implementation. i cannot find the
very line to draw
: the caret. i known the win32 API uses src/mwin/winlib/caret.c to implement
the caret.
:
: Q1: will you please tell me which line to show or hide the caret?
: or, is the caret implemented in flnx but not nanox?
Yes, the caret.c file is the implementation for the win32
caret. However, the nano-X API nor FLNX uses this
method. Instead, FLNX implements a caret using the
nano-X GrSetCursor API to change the graphical cursor.
:
: and, i want to use nxkbd and mouse to input characters, but some times,
the nxkbd will be always
: lower than the main-window which is going to be inputted, so, the nxkbd
will be invisible!!
:
: i want to solve this problem in the following way:
: when the mouse click into an editable control of APPLICATION, the caret
will be shown, at this very time,
: send message to nxkbd to RAISE window; when the caret is hide, send
message to nxkbd to LOWER window.
You will need to either modify the window manager, or
modify internals of nano-X to send a message to
a registered application (not yet implemented) whenever
the focus changes. We don't quite implement selecting
for events for ANY windows, so you'll need a method to
tell the window manager to catch all focus changes.
Easier method would be to modify nanox/srvutil.c and/or
nanox/srvevent.c to send an event to a single window
whenever the focus changes. This window id would be
the nxkbd window id.
:
: Q2: how to send message from APPLICATION to nxkbd?
: will you please give me a suggestion?
You can just execute a GrRaiseWindow from the internals
using nxkbd window id.

Greg
