OS4 native FTP client

That's a clever idea.
sftp has a similar set of commands, but it accesses the same port as ssh does. So somehow a "sftp" session should established so sftp-server is launched and not just the default shell (by sshd). But you probably will get into that in future.

I extended bitmap.image instead of button.gadget but the solution still works great for me.

Here are some C++ snippets to get you going...

struct InstanceData {
BitMap* bitmap;
uint32 width;
uint32 height;
};

IClass* iclass =
IIntuition->MakeClass(0, 0, BitMapClass, sizeof(InstanceData), 0);
iclass->cl_Dispatcher.h_Entry = reinterpret_cast<HOOKFUNC>(dispatcher);
iclass->cl_Dispatcher.h_SubEntry = 0;
iclass->cl_Dispatcher.h_Data = 0;

uint32 dispatcher(IClass* iclass, Object* obj, Msg msg)
{
uint32 retval = 0;

switch ( msg->MethodID ) {
case OM_NEW:
{
retval = IIntuition->IDoSuperMethodA(iclass, obj, msg);

InstanceData* data =
static_cast<InstanceData*>(INST_DATA(iclass, retval));

opSet* op = reinterpret_cast<opSet*>(msg);
data->bitmap = reinterpret_cast<BitMap*>(
IUtility->GetTagData(BITMAP_BitMap, 0, op->ops_AttrList));

data->width =
IUtility->GetTagData(BITMAP_Width, 1, op->ops_AttrList);

data->height =
IUtility->GetTagData(BITMAP_Height, 1, op->ops_AttrList);

break;
}
case IM_DRAW:
{
impDraw* imp = reinterpret_cast<impDraw*>(msg);

InstanceData* data =
static_cast<InstanceData*>(INST_DATA(iclass, obj));

Image* image = reinterpret_cast<Image*>(obj);
int32 dx = image->LeftEdge + imp->imp_Offset.X;
int32 dy = image->TopEdge + imp->imp_Offset.Y;
uint32 iwidth = image->Width;
uint32 iheight = image->Height;

if ( iwidth > data->width ) {
dx += (iwidth - data->width) / 2;
}

if ( iheight > data->height ) {
dy += (iheight - data->height) / 2;
}

uint32 bgpen = 0;
(void)IIntuition->GetAttr(IA_BGPen, obj, &bgpen);

IGraphics->SetAPen(imp->imp_RPort, bgpen);
IGraphics->RectFill(imp->imp_RPort, dx, dy,
dx + data->width - 1, dy + data->height - 1);

(void)IGraphics->BltBitMapTags(
BLITA_Source, data->bitmap,
BLITA_UseSrcAlpha, TRUE,
BLITA_Dest, imp->imp_RPort,
BLITA_DestType, BLITT_RASTPORT,
BLITA_DestX, dx,
BLITA_DestY, dy,
BLITA_Width, data->width,
BLITA_Height, data->height,
TAG_END);

break;
}
default:
{
retval = IIntuition->IDoSuperMethodA(iclass, obj, msg);
break;
}
};

return retval;
}

Work continues... today it transferred its first files

I still have a LONG way to go before it can be even considered beta, but already its multithreaded, and supports simultaneous browsing while downloading (provided the server allows multiple connections).

@xeron

Looking good! I just hope we won't need to wait forever for it...

@xeron

Looks like a where useful program.

What type of GUI are you using?

@xeron

Looking good!

@xeron

i've said it before, but i am gonna say it again,
your ftp app looks really slick!
looks like it will put all other amiga clients to deep shame! :D GO GO GO!

Its a ReAction GUI.

Oh yes! I hope this project sees completion.

Progress continues.

Sending and receiving now works (although only passive mode is implimented so far).

The download/upload manager is starting to work. You can queue downloads and start them later, or add to the queue and start immediately. There is a little icon showing whether a transfer is active, queued or paused.

I started work on drag and drop. I first tried subclassing the listbrowser gadget so that i could detect if the user clicked and dragged out of the side, but if you subclass the listbrowser, it disables smooth scrolling via ScrollRaster() and becomes clunky and horrible.

I then tried IDCMPHook, but you can't get left mousebutton down events over gadgets, they seem to be swallowed up before the hook is invoked.

HOWEVER, I can read middle clicks over gadget, so (for now at least) drag and drop works from the middle mousebutton.

A brief summary of whats already done:
* Sending and receiving
* Modular multithreaded design
* Browse while downloading (if server allows multiple connections)
* Drag and drop
* Multi-window support (although it is as easy and quick to use as a classic 2-pane client, and not as fiddly as most multi-window clients).
* FTP server address book
* FTP session logging

Still to do before I can even call it beta (there will be public beta releases before the stable release):
* Allow to pause or abort current transfers
* Direct FTP to FTP transfers
* Non-passive transfers
* Auto binary/ASCII detection (optional :)
* File management (deleting files, making/deleting directories)
* Transferring whole directories
* Impliment the stats panel of the control window
* Session log saving
* Proper error message requesters

Stuff I intend to do after everything above is done (although not necessarily for the first stable release):
* SFTP
* ARexx port
* Lots of keyboard shortcuts
* Locale support

Another shot (although not very much different to the last one)

@xeron

ehi dude... when a beta for os4 betatesters??

@xeron

I've some question: do you plan to add feature of preserving original (ie. source side) time and date of the file(s) after downloading?
It could be very useful to have such functionality possibly as a switch in prefs (preserve / not preserve).
There is need to swap along with FTP the files for archivisation purpose, so having the original (source) date is necessary.

Keep up the good work !

@AmiZaP

That is certainly possible, yes.

@xeron

Thanks xeron for your good work! Now We just need more...

Progress still continues

Key improvements since my last report:

* Both passive and active transfers are now implimented
* You can pause, resume or cancel any pending or active transfers
* You can transfer whole directories (either just the files, or
all subdirectories and their files too)
* You can delete directories and all their contents
* You can rename files
* You can create directories
* Optional automatic binary/ascii mode selection (based on
filename extension)
* You can save FTP session logs
* Error reporting and handling is much improved


Still to do before I can even call it beta (there will be public beta releases before the stable release):
* Direct FTP to FTP transfers (and also local to local ones)
* Impliment the stats panel of the control window
* Further improvements to error reporting and handling


There is a detailed changelog here.

@xeron

Excelent work!

@xeron

Cool stuff.

Until you release your program people can used this

@orgin

Yeah. it'll help tide people over, but (IMHO of course), pftp will be a lot better

@xeron

pFTP fih deh win!
