multiple questions
|
|
|
|
|
==================
|
|
|
|
|
|
|
|
|
|
For modular mode, we should implement a kind of stack: Save the current
|
|
|
|
|
question if any is available, then after exec_() restore it.
|
|
|
|
|
|
|
|
|
|
For async questions, we check if we're currently asking *any* question
|
|
|
|
|
(sync/async), and if so, add the question to a deque instead. After a question
|
|
|
|
|
gets hidden (e.g. in on_mode_left?), we check if another question is in the
|
|
|
|
|
deque, and if so pop and ask it.

Multiwindow
|
|
|
|
|
===========
|
|
|
|
|
|
|
|
|
|
cmdutils.register (and thus Command) gets argument scope which is global/window
|
|
|
|
|
|
|
|
|
|
when scope=global, instance is searched starting with the application
|
|
|
|
|
singleton.
|
|
|
|
|
|
|
|
|
|
when scope=window, instance is searched starting with the window the command
|
|
|
|
|
was executed in.
|
|
|
|
|
|
|
|
|
|
Each window has its own CommandDispatcher, which adds the window as an
|
|
|
|
|
attribute to every Command before calling the handler. The handler then uses
|
|
|
|
|
this to get the starting point for instance=.

IPC

|
===
|
|
|
|
|
|
|
|
|
|
We use QLocalSocket to communicate with another instance
|
|
|
|
|
TODO: find out why many apps just use QLocalSocket as a control channel, and
|
|
|
|
|
shared memory for data.
|
|
|
|
|
Max data size might be 8k, but this is enough for commandline args.

Netscape cookies

- Second column (flag): TRUE if domain starts with ., else FALSE
|
|
|
|
|
- if a cookie is a http-only cookie domain is prepended with a #HttpOnly_
|
|
|
|

- Python's http.cookiejar.MozillaCookieJar might help

Caching
|
|
|
|
|
=======
|
|
|
|
|
|
|
|
|
|
QNetworkManager.setCache() and use a QNetworkDiskCache probably
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Element selection detection
|
|
|
|
|
===========================
|
|
|
|
|
|
|
|
|
|
Possible options:
|
|
|
|
|
- javascript: http://stackoverflow.com/a/2848120/2085149
|
|
|
|
|
- microFocusChanged and check active element via:
|
|
|
|
|
frame = page.currentFrame()
|
|
|
|
|
elem = frame.findFirstElement('*:focus')
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Completion view (not QTreeView)
|
|
|
|
|
===============================
|
|
|
|
|
|
|
|
|
|
Perhaps using a QHBoxLayout of QTableViews and creating/destroying them based
|
|
|
|
|
on the completion would be a better idea?
