Well, at least one thing is working. ::)

The stupid ICCCM says clients are supposed to support the TARGETS property, but apparently they didn't feel like doing that. So that means I still have to guess what format images will be in.

I think the only way forward is to write a modified version of xclip that supports images and then call that from the program that wants to use the clipboard. Ideas anyone?

Thanks for your help testing stuff Arthur. :)

Edit :
Made it to 100 posts! Woo! :D

To any helpful Linux users :

Do any of you have the x11proto-core-dev package installed, or could you install it, and then post usr/include/X11/Xatom.h for me please? I'm trying to find an updated list of the target atoms currently in use so I can determine which formats to support. Since I'm not on Linux, package managers won't work for me, and the header I need wasn't included in the X11 library source code. Thanks to anyone who takes the time for me. ;)

Well, I guess that XA_CLIPBOARD is an extension of some kind then. I just thought it would be part of the core X11 library. I don't need it anyway, as XInternAtom(display , "CLIPBOARD" , true) finds it anyway.

I'm getting close to having a working clone of xclip that will have support for images, but it won't support images until I find out what format image editors are using to copy/paste images. Luckily my version of xclip will log what selection targets are available and are requested by other programs, so the more it gets run, the more information I will have.

Once my program is complete, I will bump the thread and post it.

Append :
Okay, here's my version of xclip, along with a version of ClipboardTest designed to use it. Linux users compile and test please. ;D

ClipboardTest10.zip
You'll need to compile both programs separately this time and the command line should be something like :

gcc -O2 -Wall xcsi.c -LX11 -o xcsi.exe
gcc -O2 -Wall ClipboardTest.c Clipboard.c -o ClipboardTest.exe `allegro-config --libs`

To test, run ClipboardTest.exe. Copy text or an image in another program and then press the L key in ClipboardTest.exe. Do this for as many programs as you have that support copying text or images.

After that, try setting the clipboard string using S and getting the clipboard string using B.

When you're done, please post the contents of ClipboardLog.txt and xcsi_log.txt.

Thanks again for helping me test this. ;)

xcsi.c cannot compile because you forgot xcsi.h in the archive.

the second one gave lots of compilation errors because you forgot to incclude stdio.h in the top of Clipboard.h, then it compiles cleanly. Of course it won't let me do anything until xcsi is built.

I fiddled with xcsi.c for about an hour to get it to compile.
Some errors were just typos such as backslashes in the #includes or no trailing semicolon to a statement, but most of my "fixes" were just wild guesses.

Now my brain's too fried to figure out what to do with it. It seems to work, but I haven't fiddled with it much. The Clipboard program just exits immediately again.
Maybe tomorrow.

Altered xcsi.c is in the paperclip.

Okay, I made a diff using your altered xcsi.c and I updated mine to fix everything you pointed out. I had to change some of your changes though, so here's the new source code (ClipboardTest.c changed some as well) :

ClipboardTest12.zip

Now, if it quits, it should output why it quit if you run it from a console. I don't know if you need to specify a special flag with gcc to link it as a console application or not though. On MinGW, the flag is -Wl,--subsystem,console. So if it quits and you don't get any output, try that.

Also, thanks for compiling it. If I had Linux and gcc I wouldn't post code with so many errors in it.

You appear to be trying to execute your xcsi program with a .exe file extension in Linux... :-X Linux executables generally don't have file extensions unless they're libraries (e.g., .so), scripts (e.g., .pl), .NET/Mono executables (e.g., .exe), or proprietary installers (e.g., .bin). :-X Since xcsi is a C program I would recommend updating the code. :P

I might. I have a free hard drive I could install it on, but then I would have to use the BIOS to pick the hard drive to start from each time. I could also try to install it using VirtualBox, but I really have no idea how that works. I'm not sure if I need a preinstalled image, or whether I could run VirtualBox and then install Linux normally.

bamccaig said:

You know, 7-zip lets you view archives before you unzip them... Besides, if I zipped the directory the stuff was in, there would be a whole bunch of other stuff with it.

bamccaig said:

Fine. Fixed.

You undid some of the things I did to get it to compile. I don't want to guess again.

Sorry about that. I skipped fixing the 'true' values at first, but then forgot to come back and update it to 'True'. Still getting used to using XLib.

Log file said:

RetrieveTarget warning : QueryAvailableTargets says this target is unavailable. Proceeding anyway.
RetrieveTarget failure : No selection owner.

Did you copy something before you tried that? XGetSelectionOwner should work right, at least.

Anyway, I fixed all the errors you posted, and modified ClipboardTest.c and Clipboard.c to rename xcsi.exe to xcsi, so don't use the exe extension when you compile xcsi.c this time.

Here's the latest version. 3rd (13th) time's a charm?

OK, they all compiled this time.

Step by step test:
Run the clipboard executable.
Copy this line in a.cc reply box by dragging mouse.
Pressed B key and see the text appear correctly.
Pressed the S key and see the message about copying "CyberMan".
Pressed B key again to see "CyberMan" appear.
Pressed C key to see message "Could not set the clipboard bitmap to the CyberMan image"
Pressed V key to see message "There is no image in the clipboard to view".
Opened Cyberman_80x80.bmp with kolorpaint, select all and copy.
Pressed V key to see message "There is no image in the clipboard to view".
Pressed L key.

The resulting log file is in the paperclip.

[EDIT]

Virtual machines are pretty easy. You use the GUI to "create" a new machine,
you get a plethora of options as to the size of the virtual hard disk, how much
memory, to use the actual hardware DVD drive or to mount an ISO file, etc.
Then you either put the actual install disk for the OS into the drive or point
the virtual CD at the ISO, start the machine and install (in the window) just like
it was a real machine.
You may or may not have some trouble running hardware accelerated programs, but A4
and gcc should work fine. It will be slower than the real thing, obviously, but
not too bad.

Yes! Now we're getting somewhere. :D

Try copying an image in Firefox and then press the L key to log the available targets. I'm curious to see what targets it supports and whether they are different from the ones kolourpaint supports.

bamccaig, it would help if you tested copying images and text from other programs (assuming you have different image editors than Arthur, for example Gimp or Paint.net or whatever else you might have) and then pressed the L key in ClipboardTest.exe. All I need then is for you to post xcsi_log.txt.

Edit -
Regarding VM's, I don't know if my laptop's hardware will be supported properly because I have to download custom drivers from Gateway that are only for Vista. Do you think that Linux ATI drivers will support my integrated graphics card?

I clicked on your avatar, right clicked to "View Image", then clicked on it again and selected "Copy Image" and ran the executable, only to have it say "There is no image in the clipboard to view" again. Log is in paperclip.

[EDIT]

You can't install hardware drivers to a virtual machine, it tries to emulate them with its own "drivers" but sometimes fails. It'll work with software rendering though, otherwise it couldn't even show a desktop.

That's okay. I couldn't add image support until I figured out what targets they were using to transfer images. Now maybe I can hack something together over the next few days. I'll have to make some custom functions to read/write a bitmap/jpg/png to memory though. Thanks for everything you've done so far, you've been a great help to me. ;)

I might. I have a free hard drive I could install it on, but then I would have to use the BIOS to pick the hard drive to start from each time.

That's what I used to do. It's not too bad to put up with depending in the BIOS and how often you switch. I did get tired of it though. With experience, I learned to just boot Windows from Grub, and make Grub my boot loader for all. :)

Depending on your distribution of choice (I generally use Fedora), the installer might even prompt you to add other partitions that it detects an operating system on (i.e., other Linux installs and even Windows). If not, it's relatively easy to manually add Windows to your grub.conf. After that, you modify the CMOS settings to always boot from your other hard drive (with Grub on it) which will provide you with a menu to choose from. You may need to alter the timeout though because IIRC Fedora 13's default timeout is 0, which basically means there's no time to actually choose an option. I changed it to like 3 (seconds) so there's enough time to interrupt it if you need to (the countdown stops if you interact with it), but it doesn't slow down booting too much. You can also pick the default boot entry, so if you want Windows to boot normally you can set that up.

You know, 7-zip lets you view archives before you unzip them... Besides, if I zipped the directory the stuff was in, there would be a whole bunch of other stuff with it.

I'm in Linux and don't use GUI tools for regular tasks. That's far too slow. I do it from the command line. I can (and do, from experience) view the contents of archives before extracting them, but it's always a pain when I find an archive that doesn't have a root directory; it means I need to create one, which slows me down. When I don't need to create one then I can generally just recall my last command, change a t or l to x and I'm done. :)

bamccaig, it would help if you tested copying images and text from other programs (assuming you have different image editors than Arthur, for example Gimp or Paint.net or whatever else you might have) and then pressed the L key in ClipboardTest.exe. All I need then is for you to post xcsi_log.txt.

You promise it won't do anything malicious? >:( (I don't feel like trying to make sense of all of the code :P)

With VMs, the only piece of hardware from your machine the OS in the VM can ever hope to see the processor. EVERYTHING else is a set of hardware that the VM maker chose to emulate.

I think Sound Blaster 16 might be an option if you want to put DOS in a VM.

Don't expect that to work yet, because I haven't added that functionality in yet.

What would help though, is if you copied an image using (Gimp , Paint.net , etc...) and then pressed the L key in ClipboardTest.exe and posted xcsi_log.txt.

That will tell me the selection targets that they have available for images, and therefore, how to support copy/paste of images. So far, I've seen image/png, image/bmp, and image/jpeg so those are the ones that I'll try to support for now.

Append -
Well, I've looked into loading/saving bitmap images into memory, and it wouldn't be pretty. I would have to re-implement packfiles as memory files to be able to hack a version of allegro's load_bmp and save_bmp functions to work for our purpose.

The easiest thing to do is to use allegro's built in load_bitmap and save_bitmap functions to load/save a BITMAP* as a temporary file which is piped to xcsi as binary data or piped from xcsi's output to a temporary file. So that is what I did. At least this way, every file format supported by allegro's load/save functions can be used.

This version does not yet have support for INCR transfers, so it may not work for retrieving large images.
