XXX - The current icon size is fixed at 16x16 pixels, which looks fine
|
|
|
|
with kwm (KDE 1.x's window manager), Sawfish (the "default" window
|
|
|
|
manager for GNOME?), and under Windows with Exceed putting X windows
|
|
|
|
on the Windows desktop, using Exceed as the window manager, as those
|
|
|
|
window managers put a 16x16 icon on the title bar.
|
|
|
|
|
|
|
|
The window managers in some windowing environments (e.g. dtwm in CDE)
|
|
|
|
and some stand-alone window managers have larger icon sizes (many window
|
|
|
|
managers put the window icon on the desktop, in the Windows 3.x style,
|
|
|
|
rather than in the titlebar, in the Windows 4.x style), so we need to
|
|
|
|
find a way to size our icon appropriately.
|
|
|
|
|
|
|
|
The X11 Inter-Client Communications Conventions Manual, Version 1.1,
|
|
|
|
in X11R5, specifies that "a window manager that wishes to place
|
|
|
|
constraints on the sizes of icon pixmaps and/or windows should
|
|
|
|
place a property called WM_ICON_SIZE on the root"; that property
|
|
|
|
contains minimum width and height, maximum width and height, and
|
|
|
|
width and height increment values. "XGetIconSizes()" retrieves
|
|
|
|
that property; unfortunately, I've yet to find a window manager
|
|
|
|
that sets it on the root window (kwm, AfterStep, and Exceed don't
|
|
|
|
appear to set it).
|
|
|
|
|
|
|
|
The X Desktop Group's Window Manager Standard specifies, in the section
|
|
|
|
on Application Window Properties, an _NET_WM_ICON property, presumably
|
|
|
|
set by the window manager, which is an array of possible icon sizes
|
|
|
|
for the client. There's no API in GTK+ 1.2[.x] for this; there may
|
|
|
|
eventually be one either in GTK+ 2.0 or GNOME 2.0.
|
|
|
|
|
|
|
|
Some window managers can be configured to take the window name
|
|
|
|
specified by the WM_NAME property of a window or the resource
|
|
|
|
or class name specified by the WM_CLASS property and base the
|
|
|
|
choice of icon for the window on one of those; WM_CLASS for
|
2006-06-06 23:11:31 +00:00
|
|
|
Wireshark's windows has a resource name of "wireshark" and a class
|
2006-05-31 19:12:15 +00:00
|
|
|
name of "Wireshark". However, the way that's done is window-manager-
|
2005-08-20 14:02:00 +00:00
|
|
|
specific, and there's no way to determine what size a particular
|
|
|
|
window manager would want, so there's no way to automate this as
|
2006-05-22 07:29:40 +00:00
|
|
|
part of the installation of Wireshark.

to the X root window. If I understand the documentation correctly,

gdk_window_get_deskrelative_origin applies mainly to Enlightenment

and gdk_window_get_root_origin applies for all other WMs.

The code below tries both routines, and picks the one that returns
|
|
|

the upper-left-most coordinates.

one such window and such a window has already been popped up - we

pop up the existing one rather than creating a new one.
|

|

XXX - we should request that it be given the input focus, too. Alas,
|
|
|
|
GDK has nothing to do that, e.g. by calling "XSetInputFocus()" in a
|
|
|
|
window in X. Besides, using "XSetInputFocus()" doesn't work anyway,
|
|
|
|
apparently due to the way GTK+/GDK manages the input focus.
|
|
|
|

|
|
|
The X Desktop Group's Window Manager Standard specifies, in the section
|
|
|
|
on Root Window Properties, an _NET_ACTIVE_WINDOW client message that
|
|
|
|
can be sent to the root window, containing the window ID of the
|
|
|
|
window to activate; I infer that this might be the way to give the
|
|
|
|
window the input focus - I assume that means it's also de-iconified,
|
|
|
|
but I wouldn't assume it'd raise it.
