Executing c command in c

[nicholas]

Good to know thanks.

I'm starting to think I might give up or change language as I'm just not finding anything that I is useful to help me understand what to do. Except for the help here which was great.

For example I'm now trying to open a jpg picture in mui.
I found how to play a sound in mui but nothing about pictures.
I found one tutorial that says how to create a datatype object but nothing on how to set that object as a picture or how to display said picture in a window.
I looked at mui_image. I think I have to use the OLD_Image attribute because I didn't see anywhere else to set the image.

I've managed to create a listview with a list that is loaded from a file and when I double click an item in the list it runs an event (Currently shows me the contents of the directory of where the file is stored in the console). I tried to find information on how to do something for a single click .
The only thing I can find that seems to make sense is select_change (https://muidev.de/wiki/Documentation/API/MUI_Listview#MUIA_Listview_SelectChange)
but this only works if I hold the mouse button down and drag it up and down the list.

So I'm thinking it's either keep asking lots of questions here or just give up and as I don't want to annoy people with my questions I'm leaning towards the give up.

This is an old but useful guide to developing in C for the Amiga.

A nice MUI tutorial

If you use IRC the #mui channel on Freenode is a good place to ask questions.

Thanks for the advice nicholas though were the 2 links supposed to be to the same site.
I did find that site but I was looking through an example I downloaded from it but the comments were not in English.

I managed to get an image loaded using Dtpic.
It wasn't working earlier but I think I was using an old version of mui as I downloaded the latest from muidev.de and Dtpic worked.

There's also some demos in this version that I didn't have which seem to do things that I need so I can try and learn the code.

Doh! I posted the wrong first link lol

This is the correct one http://aminet.net/package/dev/c/ACM

These are also handy, they are quite Amiga generic and not so MorphOS specific.

And the bombjack site has PDFs of the RKRM's and almost every Amiga development book ever published.

Another handy site for reference

Some good articles in this repo too

There's always the excellent Hollywood if you give up on C though.

It's powerful yet simple.

Haha I thought it was strange they both linked to the same page.
. I'll have a read through those other sites tomorrow.

I looked at Hollywood but I read somewhere that it doesn't allow you to launch external programs which is why I avoided it as its something I need.


I've managed to get images changing with a single click now using

Code: [Select]


DoMethod(list, MUIM_Notify, MUIA_List_Active, MUIV_EveryTime,
app, 2,
MUIM_Application_ReturnID, DISPLAY);
   
Where DISPLAY contains a set attributes function on my DtPic object.

So I think I'm going to keep trying for a bit.
I should have enough information now to help me understand what I'm doing

Excellent! I look forward to seeing your first creation when it's finished.

Hollywood does support launching external programs though btw.

Oh no way. If I knew that would have looked into getting hollywood as it looks much easier.

If I get stuck again I'll definitely consider changing to it.
For now I'll just convince myself I made the right choice because I'm learning useful things.

You can't go wrong with C, no pain no gain.
