| [ROOT] Re: help with root GUIbuilder Ilka Antcheva 16:51:23 |
| | Hi Nagaraj
At its current state the GUI builder can only help you to create and
layout different GUI elements of your application. You may consider
the saved GUI as a part of the application constructor or dialogs
related to it. The easiest way to add functionality to the created GUI
functional is the use of signals/slots communication mechanism (see
"Event Processing: Signals and Slots" on page 394 at
ftp://root.cern.ch/root/doc/chapter26.pdf and
http://root.cern.ch/root/HowtoSignalSlot.html).
Cheers, Ilka

Eliacem,
<big rant>
Poor planning on your part does not constitute an
emergency on my part.
For you to learn, you need to do the programming
yourself. You should get a grade that reflects what
you can do, not what I can do. I took classes and
passed them on my own. I do not need to write your
program to prove anything or to get a grade. Are you
going to share your grade?
What are you going to do when you get a programming
job based on the grade you got for somebody else's
work? Are you going to get someone to do your work
then also? Will you share your paycheck with them?
This group is here to help you, not to do your
homework for you. You put forth some effort to write
the code you provided, now work harder and get the
rest of the code written. I gave you some detailed
hints on what you need to do. NOW DO IT!!!!
</big rant>
Ray

| RTL and __int64 bug for BC5.02 Mohsen 18:15:01 |
| |
Hi all,
I found out that BC5 has some bugs among which /= operator for
__int64 and RTL bug for allocating huge blocks of memory are
notable. I'm using BC5.02 and I tested the __int64 type, but I
did not face any problem with /= operator as if the bug has been
eliminated in this release of BC. I don't know if that's true or
not.
It is also important for me to know if the RTL bug still exist
and how it can be tracked and removed. In my version of BC5.02 there is no source code for RTL libraries.
Many thanks
Mohsen

| [ROOT] Graphical User Interface Tom Roberts 14:09:13 |
| | I am trying to build a GUI. Unfortunately the documents are sparse, as
are examples.
The TGComboBox and TGListBox do not have sensible default sizes.
Unfortunately, the only example using them, guitest.C, contains
HARD-CODED sizes for them -- a very bad idea.
How can I set reasonable default sizes for my widgets?
How can I determine how many pixels an "M" is, wide and tall, for the
default font of these widgets?

| Set the file attribute... Popeye137 16:24:30 |
| | Hello everyone,
I would like to ask how to set a read-only file to a non-read-only file.
i tried to to use
CFile::SetStatus
static void SetStatus( LPCTSTR lpszFileName, const CFileStatus& status );
throw( CFileException );
Parameters
lpszFileName
A string that is the path to the desired file. The path can be
relative or absolute but cannot contain a network name.
my problem is that the file is located in a network computer and not a
local file. so CFile::SetStatus wont work.
Do you know any work around on this?
Thank you very much...
Regards,
Rommel

I have a problem with my project linkink.

referenced all externals from previous unit (about 16000). If I try to link
