[E-devel] Position bug?

Hi,

I tell a program to remember it's virtual desktop and position.
When I start the program from an other desktop or from startup/.order
the program starts on the desired desktop but the position are wrong. It
always starts in the upper left corner!

And now the program has a new position in memory and will start in the
corner every time until I move it to a new position!

Bug or a feature?

	Well, the get/put functionality is actually a kind of "last
resort" thing. It's generally very slow to 'get' from a display
target.. but it would be there for very particular obj types that
need an argb copy of what's already been rendered in order for it
to 'do its thing'.. Most objs would not need this.
	What they would use is some form of compositing to the
display target, or to a target specific buffer surface.

But there is a module in e_modules (bling?) which is a preliminary 
composite manager. Needs more work though.

Re: [E-devel] C++ bindings for EFL?

Hey,

I know the first one (iirc, the dev is on that list, or e-users)
i didn't know the second, but there is no file rleased, and nothing in 
cvs. Also, the home page does not exist.

[E-devel] [PATCH] cpu module for >1 cpus

I had to modify the CPU module a bit to make it show the usage of both
of my CPU cores. I checked it for compatibility on another machine with
a plain normal Pentium 3 CPU.
Without the patch the CPU module only shows the summary of both cores
divided by 2 on the left and always 0% on the right.

[E-devel] Edit / create issue in e_border.c

As far as I can tell, you always get the "Create Icon" instead of "Edit
Icon" border menu entry unless bd->app is set.  Typically bd->app is
only set if the border icon came from the E_App, all other methods leave
bd->app empty.  Most of these other methods have priority over the
E_App icon.  So, even though there may already be an E_App (.eap
or .desktop atm) on disk, you may not get to edit it, only create a new
one.

Creating a new E_App from the border menu also sets the bd->app, but
that's not gonna help for pre existing E_Apps.  Also, any number of
things in e_border.c will clear bd->app, I haven't determined what
triggers all of those yet.

If no other border icon is found using other methods, then
e_border_icon_add() uses a couple of methods to search for the E_App.
e_border_icon_add() is used from a few places.  I'm wondering if we
should search for the E_App regardless of any other source of the icon,
so that any pre existing ones can be edited via the border menu.  May
be a performance hit, I dunno yet.  Being less aggressive about
clearing bd->app might also help.  Alternatively, do a search for
bd->app at border menu creation time.

I'm open to suggestions.

This would be really a must. As I am currently playing with some sdl engine, I 
see quite a lot of redundant code that could really benefit from some kind of 
surface allocator/destructor. Perhaps a first step would be to add this 
function to the current engine design.

[E-devel] _NET_CLIENT_LIST problems

It seems to me that the _NET_CLIENT_LIST atom is giving an incorrect
list of window Ids.

I have a piece of code that iterates though the returned list and this
code works fine outside of e17, but it breaks inside :(

Any clues as to what is wrong? netwm.txt says that this is supported...

There has been a lot of changes since it was added, so no wonder it's wrong.
