<![CDATA[I want to reserve space for the taskbar using Xlib.]]>I'm currently working on my own Linux distribution, and I'm designing a window that behaves like a taskbar.
I researched how to secure an exclusive area for the taskbar,
and found out that it's possible by modifying the X11 _NET_WM_STRUT property.
I tried the code below, but it doesn't work.
How can I make it work?

Display *display  = QX11Info::display();

    long insets[4] = {0, 0, 500, 0};

    XChangeProperty(display,
                    winId(),
                    XInternAtom(display, "_NET_WM_STRUT", False),
                    XInternAtom(display,"CARDINAL",False) ,
                    32,
                    PropModeReplace,
                    (unsigned char *)&insets, 4);

You might want to check projects such as LXQt that provides a desktop environment built on Qt for inspiration.

I shouldn't have asked this in a Qt topic, since what I asked about was an Xlib issue...

How is your question related to Qt? Isn't it pure X11 / Linux specific code?

How can I make it work?

I assume not with Qt, it might be out of range of something you can control by using Qt.
