I'm making a new plugin: thumbnail

[stjepan]

Here's an early screenie:

This is actually hacked switcher. It's my first Compiz plugin so I don't know very much about Compiz, but I'm progressing slowly (making it two days now).

I have one problem with it though. in thumbPaintScreen function I have this:
Bool status;

SWITCH_SCREEN (s);

if(activated)
mask |= PAINT_SCREEN_WITH_TRANSFORMED_WINDOWS_MASK;

{
UNWRAP (ss, s, paintScreen);
status = (*s->paintScreen) (s, sAttrib, region, output, mask);
WRAP (ss, s, paintScreen, switchPaintScreen);
}

return status;
The mask slows down everything a lot. Rotating cube while thumbnail is activated is very slow. Can I tweak this somehow to speed things up?

OK the bugs are dead now :)

I've got a question:
Can I get pixmaps of minimized windows?

[mikedee]

Items 2 and 3 are related to getting the texture of unmapped windows. I am not sure if it works or not yet though.

http://lists.freedesktop.org/archives/compiz/2006-November/000870.html

In theory, it should work the same way as getting the pixmap for a mapped window. If it doesn't work then it is likely he hasn't finished those bits yet. It should all work soon.

[stjepan]

Thanks.

Next question: I want to send my plugin via dbus window id. How to implement this? What should the dbus-send command look like? How to get that window id in the plugin?

[mikedee]

If you want to get your plugin to thumbnail a particular window then you need to use the getIntOptionNamed function. Something like this.

static Bool
thumbnailInitiate (CompDisplay *d,
CompAction *action,
CompActionState state,
CompOption *option,
int nOption)
{
int window_id = getIntOptionNamed (option, nOption, "window_id", 0);

.....

All your action options are automatically available to dbus and are available with dbus-send like this.

dbus-send --type=method_call --dest=org.freedesktop.compiz /org/freedesktop/compiz/plugin_name/allscreens/action_name org.freedesktop.compiz.activate parameters

Parameters are sent via dbus in key value pairs, each key and value must be typecast on the command line (keys are always strings). eg.

string:'window_id' int32:0x12345

[stjepan]

Thank you.

After playing with dbus, modifying libnwck and improving my plugin I got nice effects so I made a video.

The plugin is progressing well... here's a newer video: http://video.google.com/videoplay?docid=-6092022018589488823

I have another question: how can I get event when scale, switcher, zoom or inputzoom are initiated? Is this possible?

I dont have flash at the moment (and64) so I cannot see it :(

Its a good question and as far as I know it isn't possible at the moment (other than by polling the otherScreenGrabExists function). It is needed for a few other plugins so I think I will try to send a patch. It would be nice to have how it was initiated (eg, by key/mouse/edge/other).

PS - Moved to Plugin Development as its more relevant there

[stjepan]

Can I prevent those plugins from being activated when mine is activated?

PS - this topic is just to get help at developing the plugin, I'll make a new topic with releases, news, bugs etc.

No, they have to be written to not activate when yours has a screen grab. Its fairly easy to do. A lot of them just test to see if any plugin has a grab before not initiating. There are only a few that detect for certain plugins. Its probably nicer to make your not initiate if any plugin has grab rather than testing for specific grabs.

No problem, its more for developers so maybe developer help might be better, heres fine now though ;)

There's the download button at the right...

Tnx I'll see what can I do about those plugin "conflicts"..

[gnumdk]

It should be cool to have some code available to be able to test, debug and why not help you :)

[stjepan]

News:
* fixed borders
* I'll drop dbussing and use xproperties
* license: GPL
* added fading (will be an option) when switching between buttons

I can't release it yet, the code is still dirty, there's no gconf schema, no options, no xproperties.

I only have a nice screenshot for you:

You do not need to worry about the gconf schema, I can generate that for you if you like :)

Looking forward to a release

Tnx, what's your email address?
