setting EWM (extended window manager) hints via Qt4 (X11)

[Chicken Blood Machine]

You can use XSetWMHints like this :

#include <X11/Xlib.h>
#include <Q11Info>
 
// In widget constructor
 
// Allocate a hint structure - don't forget to XFree() in destructor!
XWMHints* hints(XAllocWMHints());
 
// Populate the hints structure with the hints you want to activate here.
// hints->flags = ...etc.
 
// Set the hints on the X11 window for the widget.
XSetWMHints(QX11Info::display(), static_cast<Window>(this->winId()), hints);

#include <X11/Xlib.h>
#include <Q11Info>

// In widget constructor

// Allocate a hint structure - don't forget to XFree() in destructor!
XWMHints* hints(XAllocWMHints());

// Populate the hints structure with the hints you want to activate here.
// hints->flags = ...etc.

// Set the hints on the X11 window for the widget.
XSetWMHints(QX11Info::display(), static_cast<Window>(this->winId()), hints);

To copy to clipboard, switch view to plain text mode 

Be careful though, it will hardly be portable...
