调整和移动活动窗口X11

Question

我试图(用python)为一个非平铺的WM写我自己的“贴图助手”，比如Xfce，MATE，ecc。此代码应将活动窗口放置在屏幕的中央、左侧或右侧。

我使用pyewmh库与X11交互。

当我试图调整大小和移动窗口时，它不能正常工作，我不知道为什么！

这是我的python代码：

import argparse
from contextlib import contextmanager
from typing import Any, Dict, Optional, Tuple, Union, Callable  # noqa

from ewmh import 

# wm manager
ewmh = EWMH()

# get desktop size and real desktop sizes
w, h = ewmh.getDesktopGeometry()
xr, yr, wr, hr = ewmh.getWorkArea()[:4]


def main():
    print("Desktop Geometry: ", w, h)
    print("Desktop WorkArea:", xr, yr, wr, hr)

    # execute user selected tiling operation
    options[args.mode]()

    ewmh.display.flush()


def __edit_window(win=None, x=None, y=None, w=None, h=None):
    if win is None:
        win = ewmh.getActiveWindow()

    ewmh.setMoveResizeWindow(
        win,
        x=x,
        y=y,
        w=w,
        h=h
    )

    if h is None:
        ewmh.setWmState(win, 1, '_NET_WM_STATE_MAXIMIZED_VERT')

    print(f"New Window {win} pos: ({x}, {y}), New Window size: ({w}, {h})")


def tile_left():
    """
        Tile window to the left part of the screen.
        -m tile_left
    """

    print(f"Left Tiling Window")

    __edit_window(x=0, y=0, w=int(wr/2)) # w or wr ??


def tile_right():
    """
        Tile window to the right part of the screen.
        -m tile_right
    """

    print(f"Tiling Right Window")

    __edit_window(x=int(wr/2), y=0, w=int(wr / 2)) # w or wr ??


def centering_window():
    """
        Centers the active window.
        -m center
        Used with --noresize the active window is not resized when centered
    """

    print(f"Centering Window")

    win = ewmh.getActiveWindow()
    win_size = get_window_size(win)

    # disable maximised_vert 
    ewmh.setWmState(win, 0, '_NET_WM_STATE_MAXIMIZED_VERT')

    if args.noresize:
        # centering windows without resize dims
        print('\t with NoResize mode')

        __edit_window(win, x=int((wr - win_size.width) / 2), y=int((hr - win_size.height) / 2), w=win_size.width, h=win_size.height)  # w or wr ??

    else:
        # centering windows and resize dims
        print('\t with Resize mode')

        __edit_window(x=(xr + 50), y=(yr + 50), w=(wr - 100), h=(hr - 100))  # w or wr ??


def get_window_size(window):
    """Returns window size object"""
    # get window dims
    win_size = window.get_geometry()
    print(f"Window pos: ({win_size.x}, {win_size.y})  Window size: ({win_size.width}, {win_size.height})")

    return win_size


if __name__ == '__main__':
    # define selectable options
    # type: Dict[str, Callable[[None], None]]
    options = {
        'center': centering_window,  # center window
        'tile_left': tile_left,  # tiling window to the left
        'tile_right': tile_right,  # tiling window to the right
    }

    # init argument parser
    parser = argparse.ArgumentParser(description='My awesome python tiling assistant !')

    # arguments
    parser.add_argument(
        '-m',
        '--mode',
        type=str,
        choices=options.keys(),
        required=True,
        help='Choose how to tile the active window'
    )
    parser.add_argument(
        '--noresize',
        action='store_true',
        help='Center window without resize it'
    )

    args = parser.parse_args()

    main()

下一张图片显示了这个问题：

两个终端之间和右侧终端与屏幕边界之间有一定的空间。

我在设置正确的窗口高度方面也有问题。我用_NET_WM_STATE_MAXIMIZED_VERT的道具修复了它，但是当我试图用鼠标移动窗口时，它有点卡在Maximesed_Vert状态了。

要使这样的脚本在不同的桌面环境(如XFCE、KDE、Gnome等)中正确工作是不容易的，因为这些DEs不同地装饰窗口。另外，CSD (客户端装饰)或不起作用。我认识一个人，他目前正在从事一个类似的项目，应该在几个DEs上工作。为了完成这项工作，他的程序收集了几个几何数据。请参见https://gitlab.com/corthbandt/shinglify/-/blob/main/ewmhbackend.go函数refresh()。

我还在python中编写了一个平铺助手，它在XFCE上工作得很好。也许你可以把它作为一个起点。我的脚本，除了平铺外，还可以同时调整并排窗口的大小.不幸的是，我不能像您一样使用EMWH-模块，因为这会在自动调整大小的过程中引起恼人的闪烁。
