I want to cut the window
I know X11 API ： XIntersectRegion XXorRegion XUnionRegion
Is there an API under Wayland that would allow me to make a irregularity window

I have a Perl/Tk window which is displayed on top of all other windows. It is a MainWindow->Frame->Label with text (it's a security classification banner). It must be a window which is on top. However, right now a user cannot move the window from its set location, so it will occasionally cover up a lower window control.
How can I make this window movable so it can be repositioned?
I don't have easy access to external modules since I'm on a closed network, so simple Perl/Tk code is best.
This is a Linux system running the KDE or Gnome desktop.
I have found that if you remove the decorations from a Perl/TK mainwindow, it cannot then respond to mouse movements.
I am new in GTK theming. Now I am trying to create theme GTK for XFCE. Everything is OK but how to remove this ugly shadow under the panel?
I don't think that shadow can be removed via a gtk theme, it is drawn by the compositor. If you are using xfwm4, to disable it open Window Manager Tweaks, go to the Compositor tab and uncheck the "Show shadows under dock windows" option.
Running xprop | grep TYPE and pointing to panel, one can learn that its type is _NET_WM_WINDOW_TYPE_DOCK and according to f.do specs:
_NET_WM_WINDOW_TYPE_DOCK indicates a dock or panel feature. Typically a Window Manager would keep such windows on top of all other windows.
I just installed Eclipse from the Android website and the dialogs have no title bar and seem to be docked at the top of the Eclipse main window. I can't find a way to move them or get the titlebar back. I'm using Gnome 3 as desktop/window manager.
For example, if I choose Search | File... from the main menu, it comes up, but without titlebar. If I press Alt+F7, I can move the entire window, but the dialog will not move relative to the window.
How do I fix this?
Thx.
You are missing an important information, your operating system and desktop environment. Let me guess? Linux/Gnome? Or Cinnamon?
Gnome has the, erm, great feature to attach modal dialogs at the main window.
You can install dconf-editor and set the key org/gnome/shell/overrides/attach-modal-dialogs to false.
In Cinnamon you can easily disable this feature in the System Settings > Windows > Attach dialog windows (may not be the actual text as I translated it from my locale). You need to switch the settings to Expert mode to see the Windows entry.
I want to change the context menu of any application that is attached to the taskbar (should be the same as clicking a folder icon left, e.g. this)
Is there any way to do this for Windows XP?
If I understand your question, you need system wide hook that handles WM_SYSCOMMAND message to modify system menu. See similar question in c#.
Modifying global system menus
In GTK programming, how to monitor desktop environment mouse event while the GTK application is not active, i.e, the mouse is focus on other GTK application?
Finally, I found a library keybinder which is what I want!
The homepage(http://kaizer.se/wiki/keybinder/) of that library introduces that keybinder is a library for registering global keyboard shortcuts. Keybinder works with GTK-based applications using the X Window System.
