XPLMCreateWindowEx

XPLM_API XPLMWindowID XPLMCreateWindowEx(
                         XPLMCreateWindow_t * inParams);

This routine creates a new “modern” window. You pass in an XPLMCreateWindow_t structure with all of the fields set in. You must set the structSize of the structure to the size of the actual structure you used. Also, you must provide functions for every callback—you may not leave them null! (If you do not support the cursor or mouse wheel, use functions that return the default values.)
