I use RECORD extension to get the protol data between XServer
and XClient.
In some cases, only NoExpose Event is sent to XClient. For
examples, open netscape and enter a web site. The page has some flash, that
is, some place keep changing in the page. in that case, I do
nothing.
Now
in X, there are many Request, and I could get X Request from
Xproto.h. For the core request, it begin from 1 and end with 127.
But X Reply code is only marked as
1 nomorl Reply
0 Error
But there are many different Reply struct, do they
all have the same reply code?
I gu
Hi All,
I intercept request between Xserver and
XClient. However, among them no display
infomation contained.
For example, if there is a intercepted
request: xCopyAreaReq from which sourcr/destination drawable is
obtained, then how can I know where the two drables locates in
Hi all,
I want to receive Expose Event during the
program. The problem is that in some case no expose event occured.
I drag a window over some windows. If the
obscured window is a common window, when some part of the window is exposed, it
will generate Expose Event. But
Hi All
Is there anyone studied the X request about
X_PolyText and X_ImageText?
As you know
XDrawString/XDrawImageString may generate these requests. And X server may
draw a background rectangle for string showing.
Now the problem is how can I get the
background rectangl
I recently study request but meet more problem.
Now the meaning of request length puzzled me. For example, the
request of X_ImageText8
typedef struct { CARD8
reqType; BYTE nChars; CARD16 length
B16; Drawable drawable B32; GContext
gc B32; INT16 x B16, y B16;}
Is there anyone familiar with RECORD extension?
I encounter a problem make me sick.
During the XRecordInterceptProc, I intercepted a request
X_ImageText8.
To get the background the string has occupied, I need to use
XQueryTextExtents (or XTextExtens and XQueryFont) to get the width and
I use XGetWindowAttributes to get window's map
state.
There are 3 state: IsUnmapped, IsUnViewable,
IsViewable.
what's the difference among them. Does Mapped window is
viewable? If yes, IsUnviewable means what?
I search the xlib functions, but failed to find one to be used
to cha
Has anyone here ever used RECORD extension?
From My test, when I start RECORD extension and begin to
intercept protocol data, then start netscape, after a while, X Server
crashed!
Is RECORD extension stabled? or something I hadn't pay
attensions?
Thanks in advance!
Hi,
I try to catch the request the client
sended. most of them can be recognised.
However, in a terminal, I type "clear"
command to clear the characters, no suitably request find.
I guess the related xlib function may be
clearwinow or copyarea or cleararea, but none look
If just switching 2 windows by clicking, we only see these 2
windows changing their frame(such as title bar become bright or dim), while
their content changing nothing.
So, How does client make server do this? I mean how do make
server only change window's frame? and which request sent
I met a problem about one extension, which contains server
side and client side. I just doubt the extension has some problem. But reading
source code make me sick and faid to find anything I need.
So, Is there any way to debug the extension? For example,
XTEST extension.
well, Get GContext from GC is very easy. But I only got
GContext and need GC information to do something, such as get a line's width
from GC.
How Can I get GC information only in client side? I
mean not searching in Server side
Thank you for giving such a nice
explanation!
Yes, I have read xnee source code and find
the work_round you marked works fine with avoiding X server crash.
I have tested RECORD in Solaris. in U5 with
os 5.9, Xserver must be crashed when launch large program like netscape
hi,I everyone! I am new here!
And I got a problem in using RECORD extension. I hope
the extension can record the changed area of screen
when I do screen sampling. And I found the recorded
data is sended throught the callback function. But
what puzzleed me is that I can't find the coordinates

Hi all
Does unix support 22KHz and 44KHz frequencies sampling rate in Audio?
Or is just just related to the sound card
installed in the OS?
