By default, the Pocket IME UI displays the candidate list window under the composition window. If there is a software input panel under the composition window, the software input panel overlaps the candidate window. This is not a problem if you can move the software input panel. If the software input panel is docked, as on a small screen, problems occur when you attempt to select the candidate window. If you plan to make the software input panel docked, you can modify Pocket IME UI source code to move the IME candidate window and avoid overlapping the IM window.
The following example modifies Cand100.cpp, the source code file that creates a candidate window. The example uses SipGetInfo to retrieve the IM window position, and to check whether the IME candidate window overlaps with it.
Note
The code modifications are noted by comment. If you want to implement this modification, insert the new code in Cand100.cpp. To make the following code example easier to read, error checking is not included. This code example should not be used in a release configuration unless it has been modified to include secure error handling.
