Hi all ,

i wrote a win32 application under windows , and i want to convert it on linux .

i want to get window handler and name and it's children and many else , i hope to find some one help me

THX

Linux doesn't support the win32 api by itself. You can run windows programs in linux using wine. I believe it is also possible to link directly with the wine libs so your users don't need to install wine, but I haven't tried this yet.

If your program uses MFC/Visual C++ I would recommend porting it to linux using wxWidgets.

Hope this helps

thx gerrit_daniels

But i meant that u can on windows api's get the window handler or it's name or even childs ,....

that's what im searching for "linux x window api"

thx again

From what you're saying I understand that you are looking for the "x.org api" to rewrite your program for linux. If that is the case then I would suggest using one of the toolkits instead of using x directly because they are much easier to use. If you're programming in c you can use GTK, if you use c++ I would suggest wxWidgets or the KDE libs.

Hope this helps

Converting a program to linux will very much depend on how you built the program.

Did you use a RAD IDE to build the windows or you built them coding? In what language did you write the program?

Suposing you coded the window and are writing in c++ the answer is: The inner windowing API for linux is X11, but it is not adequate for most gui programs, you should use a toolkit around it. Another API that makes things a lot easier and goes above X11. There are 2 main such gui APIs for linux: GTK and QT.

For a multiplatform program you could use an API that will go above GTK (and then above Win32 when compiling for windows). Some options are: wxWidgets for c++ and Lazarus LCL for pascal.

thx all very much

here's what i want :

i have made a program on windows using C++ that can retrieve any GUI running application properties (like : the window handler , window childs , containing controls , size , position ,.....) and many else
spy++ (Microsoft) is an example of it
i want to make simillar one on linux
i don't want to build a GUI window , i want to use a current running application ( what ever this app was ) to get what i want from it

you may try those XGetxxxxxx functions in this link :

I hear X11 is a real pain to program for. You might want to figure out what window manager you want it to run under (I think KDE is the most used/easiest to use/most Windows-like GUI). For that you can use Qt (http://doc.trolltech.com/3.3/index.html) which is an excellent user interface library. I think it might be more what you are looking for if you are a Win32 programmer.

i guess he just need some functions to retrieve windows attributes instead of creating a Xwindow and Xevents from scratch .........

yes alred , u r right

i don't need to build any GUI application from scratch

i just need to retrieve some attributes from an already running application ( for ex. firefox , mplayer ,...any window)

thx for everyone

if you are interested in Xlib then you may try roll your own findwindow function by using XQueryTree() , get all window IDs then get attributes .

do a google search with XQueryTree() for full C/C++ example code .....
but still you might find some ready wrapper function from qt or others ......

goodluck ......
