Summary

Control window title visibility by a new client property in XAWT on Unix desktop systems

Problem

Rich client applications (IntelliJ IDEA for example) need control over window title rendering.

Solution

Some popular X Window Managers allow controlling the window title through the "decorations" part of _MOTIF_WM_HINTS window property, namely, MWM_DECOR_TITLE bit. Extend XAWT by a client property ("xawt.mwm_decor_title") that controls the presence or absence of that bit in _MOTIF_WM_HINTS. The new client property is applied to the root panes of windows.

Specification

The new property follows the format of some existing properties:

"apple.awt.windowTitleVisible"
