Triggers resize events for clients

[blueyed]

Calling revelation triggers the resize event for clients, which makes e.g. Vim change its internal window layout (splits): because there is less space for the whole Vim window, the internal windows/splits get shrunken.
After picking a window via revelation, the original (internal) window/split layout isn't restored.

This affects any application which adjusts it's inner layout when being resized to something smaller, but does not restore it when it gets resized back to the original size.

It would be nice, if this could be avoided.

Hi blueyed,

revelation suppose to restore the window layout of every client after you select.
Could you tell me what your awesome window layout is, when it happened.
And Besides the your select client, e.g. Vim, have the layout of other clients without focus been restored?

Thank you very much.

@guotsuan
I wasn't clear enough: the awesome window layout is not affected, but the internal window/split layout in Vim: I have updated the issue's description - please re-read.

[guotsuan]

Thanks @blueyed, I think I unstood the problem now.

[blueyed]

I have no idea how that might get solved though.
For Vim in particular, it could be made to ignore the resize event maybe and/or be scripted to restore itself via the VimResized autocommand somehow.

The main issue appears to be that revelation resizes the windows though: it would be nice, if some kind of pixmaps of the clients could be used instead.

I have just seen that there's content (a client's screenshot) in the client API: http://awesome.naquadah.org/doc/api/modules/client.html#client

Thank you @blueyed for the heads up.
I think the way that you proposed is the also the best way I can image for now.
The only thing I am worried is that the taking the screenshot and using them rather than the real windows of clients could be much complicated than directly using the windows of clients.
Currently, revelation is only a simple awesome extending module. I hope I can implement this idea without introducing other dependencies.

I think that using the content property might be quite effective, in contrast to automatically calling some external program on each client at least.

[guotsuan]

I just checked the content property. I'm afraid that this field is empty unless you fill it specifically.
One may still have to fill this field by some external program. Please correct me if I am wrong.

Yes, I had asked about it on IRC already.

psychon | client.content has undefined content for the parts of the client that aren't currently visisble
psychon | not that useful for an expose effect
