can GtkWindow be a child of another GtkWindow?
Hi, I have a GtkWindow with type GTK_WINDOW_POPUP, I want it to be a child of a GtkWindow, the effect will be the pop up window can only move within the scope of the parent window. And if I invoke the position function for the popup window, the coordinat parameters is relative to the parent window. Is it possible? Or any alternative way to achieve this? Thanks.

Re: Memory debugging -- which tool?
Valgrind for most of it. However, be warned, if you have a multi-threaded application and you're trying to debug a multi-threading issue, Valgrind is not going to work for you. Valgrind does some hocus-pocus to simulate multi-threading, but you will not get the same conditions as when your application is running bare.

Setting a background image for GtkCellRenderer.
Hi,
Am facing problem setting a background image to a GtkCellRenderer, trying to
set the background image for GtkCellRenderer, using the rc file,
my intention is to set a background image(a transparent one) to a cell
which is selected,
This is the part of the rc file i am using.
style "sample-cellrenderer" {
engine "pixmap" {
image {
function= FOCUS
file= "sample.png"
border = { 0, 0, 0, 0 }
stretch = TRUE
}

Monitoring keyboard by an application in System Tray
Hi all, I want to know the procedure to monitor the keyboard for a particular key combination, by an application that sits on the System Tray. Can it be done thru' registering for signalling /callback? How is this possible in a GTK+ application? Thanks! Best Regards, Sundar Looking for last minute shopping deals? Find them fast with Yahoo!

I used to use efence, but it's valgrind all the way for me now. efence is fast but VERY memory hungry. I have a 64-bit machine now and valgrind works wonderfully well. My app needs at least 70MB of RAM on startup and that's enough for efence to run out of space on an 8 GB machine :-( valgrind is bit sluggish, but you can just go for a coffee while waiting for it to spot something. A good tip is to make a careful suppressions file so valgrind only stops your program for your errors. It makes using it much more hands-off.

Memory debugging -- which tool?
Hello, I've written some C code which at some point seems to be trampling over memory that belongs to GTK-related stuff, which causes erratic crashed at some unrelated point much later. This is of course not a GTK issue, just a well-known phenomenon in general. I'm trying to use valgrind to track down this issue; however, this slows down my app to the point where it takes close to a minute for the GUI to start up, and then another minute to get to the crash. I've used ccmalloc with good success in the past, it has very little overhead, but it doesn't seem to support gcc-2.4.1 any more. I need something faster than valgrind. What tools do you guys use?
