Asks the window manager to move this to the given position.
Window managers are free to ignore this; most window managers ignore requests for initial window positions (instead using a user-defined placement algorithm) and honor requests after the window has already been shown.
Note: the position is the position of the gravity-determined reference point for the window. The gravity determines two things: first, the location of the reference point in root window coordinates; and second, which point on the window is positioned at the reference point.
By default the gravity is NORTH_WEST, so the reference point is simply the
y supplied to move. The top-left corner of the window decorations (aka window frame or
border) will be placed at
y. Therefore, to position a window at the top left of the screen, you want to use the
default gravity (which is NORTH_WEST) and move the window to 0,0.
To position a window at the bottom right corner of the screen, you would set
SOUTH_EAST, which means that the reference point is at
x + the window width and
y + the window height, and the
bottom-right corner of the window border will be placed at that reference point. So, to place a window in the bottom right corner you would
first set gravity to south east, then write: `gtk_window_move (window, gdk_screen_width () - window_width, gdk_screen_height () - window_height)
` (note that this example does not take multi-head scenarios into account).
The Extended Window Manager Hints Specification has a nice table of gravities in the “implementation notes” section.
The get_position documentation may also be relevant.
