How to correctly use the PreeditPosition input style

[Sam Varshavchik]

I'm trying to code my own XIM client, as a hobby. Based on XIM protocol specification, and XLIB documentation here's what I'm doing:

1. I am selecting the XIMPreeditPosition|XIMStatusNothing input style, the first style listed in queryInputStyle.

2. I am setting and updating spotLocation and area.

However, ibus 1.5.14 always shows its preedit window below my main window, instead of near the "spotLocation" attribute. I am not getting any XIM_ERROR messages. XIM_SET_IC_VALUES, with each "spotLocation" and "area" attribute update, gets acknowledged without any complaints.

Am I missing some detail, some required step that I need to make? Everything appears to be working fine; the input method is working, just that the preedit area is ignoring what I'm setting for the "spotLocation" attribute.

One thing that wasn't quite clear to me is why the "area" attribute needs to be set. It seems that setting spotLocation alone would be sufficient information to inform the XIM server where in the focus window input is being entered; area seems to be redundant. I'm setting "area" to indicate where in the focuswindow the cursor is blinking, with "spotLocation" being its south-west corner. Also, my focuswindow and clientwindow is the same, it's just one large window.

Thanks for any pointers.

ibus-x11 gets the preedit position from XNSpotLocation:

Probably I think it would be better to refer xterm source codes.
