Re: Help needed to get the application work for native linux editors

Hi,

I can't really give you any advice on using the X API,
but I can tell you that the Win32 and X API are
completely different. If you want to support native X
apps then you will have to either completely rewrite
your Windows program in Linux or you will have to
compile the Linux editor as a Winelib app and run it
under Wine.
I suggest you find a good book on the X API and/or
contact the appropriate mailing lists to find out
which functions you should use.

Hai friends,

I successfully ran a script manager(keyboard Manager/driver) developed for windows (using VC++) in Linux using wine.  Its working in the wordpad application called using wine.I want to make it work in Linux editors.

The technical details about the working of the keyboard driver is as follows.
 1) The keyboard driver is a keyboard hooker program. The keyboard driver will trap all the keystrokes from the keyboard and  convert the Ascii value to the appropriate native language Character code.
 2) First we have to get the handle of the window/control where the cursor is currently located, for that the GetFocus API is used.
 3) Virtual-key code of the key that generated the keystroke message is converted to appropriate another code for making the keyboard Inscript or phonetic and send using Postmessage API.

I have some doubts. Do these APIs written for  windows work in linux. In linux , How could i get the handle of  the window where the cursor is currently located. What are the changes that i should make in the source code to make it work for linux editors. 
Looking for your suggessions. Thanks in advance .

Help needed to get the application work for native linuxeditors

Hi,

Can you tell me where I can get the help on X APIs. I am very new to
Linux programming.
I feel that replacing windows GetFocus API & Postmessage API with that of
Linux APIs might work.

The man pages are a good start, here is the Xlib manual:

Man, I feel old in the face of such enthusiasm.

Hi Saravanan,

Please, the last thing I want is to pour cold water on your enthusiasm. 
However, I'm afraid the project you are contemplating on doing here is 
in the order of magnitude of Wine itself.

You see, the thing about X windows is that they don't have an HWND, for 
the very simple reason that they are not Windows windows (not a generic 
name my %$&!@). As such, you will find that in order to do what you are 
trying to do, you will have to create a HWND representation for windows 
you don't control. It gets worse - X gets events, not messages. You will 
have to create message loops for each window you want to create a Win32 
identity for, and then figure out for each individual message how to 
translate it into the X API space. This is not a trivial job to do, and 
so far as far as I know, Wine has not handled this aspect at all. It 
just didn't seem important enough to anyone.

Wine is currently mostly handling the Windows->X translation, not the 
other way around. This means that Wine is currently figuring out how to 
make the Win32 constructs appear inside the X world. Making the X 
constructs appear in the Win32 world has never came up, as far as I know.

That said, you can search some of the following sites for the docs you 
want. http://x.org, http://xfree86.org, http://freedesktop.org.
