Re: Docky transparency on 16bit screens

@ssolie

OK. When I have time I'll try to contribute myself to this article. There is still a lot to say about setting/getting attributes, not to mention DockyProcess() stuff which is quite dodgy to use.

Re: Docky transparency on 16bit screens

Hi, For 16-bit screen, you have to use the separate 8-bit alpha bitmap targeted by alpha.RP field in DockyRenderDestination structure. Here's an extract of a conversation I had with Massimo Tantignone on this subject years ago (I hope he doesn't mind me quoting it here) : When compositing is enabled...

Re: IPrefsObject doesn't load/save XML from ENV:/ENVARC:

@javierdlr For dockies, it's better to use DOCKYGET_DockyPrefs / DOCKYSET_DockyPrefs feature. This way, your prefobject is embedded in AmiDock's own prefsobject, and you can have a separate one for each instance of your docky (in an object-oriented fashion). Check winbar.docky source code on OS4depot.

Re: "amiga.com" string still in some system programs?

In addition to their name, OS4 apps are strongly advised to provide an URL (actually, a domain name) to application.library, in order to avoid name collisions.
This URL ends up in the name of the prefs file (as in "Amidock.amiga.com.xml"), so it cannot be changed without breaking things.

Re: Docky autodoc

No the names of the functions are correct: Clone(), Expunge(), Obtain(), Release() defined as the minimum function set for Exec interfaces. Actually, the names of their implementation in the source of a docky does not matter. Only docky-specific functions are prefixed: DockyGet(), DockySet() and Doc...

Re: Interfaces: correct way of using Clone() method

Hi, Clone() is expected to build a new interface (by means of MakeInterface()), flag it as IFLF_CLONED, initialize its private data and return a pointer to it. In this case, Expunge() shall also be implemented in order to undo what was done in Clone() (free memory, etc...). Such interfaces are also ...

Re: UDMA on microA1

@Christopher Follett My Western Digital 250 GB hard drive worked ok with PIO when I installed it in my system case. Sometime later I tried some UDMA modes and UDMA5 seemed to be the best. Less than a month later, I was having issues with this hard drive (intermittant unable to boot from hard drive,...

Re: UDMA on microA1

I increased the frequency of my 750GX to 800 MHz (as 8 x 100 MHz), but I still have the same symptoms when UDMA is enabled. Given the previous posts and the number of potential causes, I will not perseverate.

Re: UDMA on microA1

@Christopher Follett That's interresting. Do you mean UDMA was causing trouble with a core frequency of 600 MHz and setting the multiplicator to 9 sort of fixed this ? I haven't tried to overclock my G3 yet because the dip switches are glued. However, if I got it right it's worth trying. I replaced ...

Re: UDMA on microA1

I tried all UDMA modes (with idetool), like I said even with the slowest one, no success.
