XtTranslateCoordinates(3Xt) MIT X11R4 XtTranslateCoordinates(3Xt)Name
XtTranslateCoordinates - translate widget coordinates
Syntax
void XtTranslateCoords(w, x, y, rootx_return, rooty_return)
Widget w;
Position x, y;
Position *rootx_return, *rooty_return;
Arguments
rootx_return
rooty_return
Returns the root-relative x and y coordinates.
x
y Specify the widget-relative x and y coordinates.
w Specifies the widget.
Description
While is similar to the Xlib function, it does not generate a server request because all the required information already is in the wid-
get's data structures.

XtQueryGeometry - query the preferred geometry of a child widget
Syntax
XtGeometryResult XtQueryGeometry(w, intended, preferred_return)
Widget w;
XtWidgetGeometry *intended, *preferred_return;
Arguments
intended Specifies any changes the parent plans to make to the child's geometry or NULL.
preferred_return
Returns the child widget's preferred geometry.
w Specifies the widget.
Description
To discover a child's preferred geometry, the child's parent sets any changes that it intends to make to the child's geometry in the corre-
sponding fields of the intended structure, sets the corresponding bits in intended.request_mode, and calls
clears all bits in the preferred_return->request_mode and checks the query_geometry field of the specified widget's class record. If
query_geometry is not NULL, calls the query_geometry procedure and passes as arguments the specified widget, intended, and preferred_return
structures. If the intended argument is NULL, replaces it with a pointer to an structure with request_mode=0 before calling query_geome-
try.

We have quite a few threads about this subject. I have collected some of them and arranged them by the OS which is primarily discussed in the thread. That is because the exact procedure depends on the OS involved. What's more, since you often need to interact with the boot process, the... (0 Replies)
I'm writing a command shell, and I want to be able to detect when the user presses an arrow key (otherwise it just prints [[A, [[B, etc.). I know it's relatively easy (although somewhat more time-consuming) to detect keystrokes in noncanonical mode, but I've noticed that the bash shell detects... (4 Replies)
I'm learning off Linux (Ubuntu) right now. I want to move up to Unix, but I don't want to rush like I did when it came to Windows --> to Linux. What is the best Unix OS that fits in pretty well with Ubuntu.
In other words is there kind of an equal Linux with Unix?
Also what do I need to... (10 Replies)
I noticed my hostname is <my-full-name>s-macbook.local. I'm not sure exactly what information leaves the local network, and whether the hostname is included, but if it is, this would mean people on the Internet can look at my hostname and see who I am. Before anyone says that's not possible,... (4 Replies)
