Don't freeze the dialog when searching

[Robin Lee]

By 0.52, when searching, the Search dialog turns frozen. It would be more friendly if a progress bar shows how much texts have been scanned and disappears when search finishes.

I hacked together an improved search dialog. It shows more clear when searching is going on, and when it ends without finding anything. For anyone who wants to test it: please download the attachment of this comment and replace the original zim/gui/serachdialog.py with it, then restart zim. Feedback is welcome!

@Robin: my 164 pages (about 700kB txt with 22MB attachments) are searched in less than a second. So I don't need a progress bar. What do you think of my attachment? Would it be ok for you, if "Searching..." is displayed instead of a growing progress bar?

[Robin Lee (cheeselee)]

Yes, your new dialog is clear. But it may be even better if moving "Searching.." to the center of the textarea.
I will change the title of this issue.

[Oliver Joos (oliver-joos)]

Ok! The default position for text is in the center anyway. I tried to mimic Nautilus Search for files, but now agree with you.

Implemented alternative fix in rev 467. Search is now responsive, shows results early and can be cancelled

Fixed in zim 0.55
