Here is our work for capturing media (@techteej and @tony) from 2 other threads and @techteej's Speech project, tidied up, wrapped in a class, closing the server and presented in a popover sized to fit the iOS pop up.
The code uses a chunk from @omz's File Transfer script.
Only tested on an iPad mini (original) and the latest iOS 7 (see below), can't vouch for others.
# see version 2.1
New version posted
New public interface attributes of: version, source, message and file name
New compatibility testing in preparation for release of IOS 8
New close button in base class to prompt user action after cancel
New sub class example: MyCaptureMedia
Update: better fix for programmatic close of popover
Notes for GitHub users regarding the items removed there:
_make_xxxmethods are according to @ccc's comments on best practices.... "Each ui element that gets added as a subview to your ui.View should have its own
The methods did load and layout are supplied as a provision for subclasses of CaptureMedia. Did load... gives the subclass the opportunity to add to or modify the ui of the class before it's presented, perhaps to make the WebView visible or leave it hidden but add extra buttons, etc. Layout gives the subclass the opportunity to change the size of the popover or adjust it for orientation changes etc.
The function of the
def log_messageis to suppress the default log messages to the console.
I posted it here on GitHub for you.
@ccc I've added some notes above regarding the purpose of the items removed in the Github edit.
Here's an example of how to make a custom CaptureMedia with the version posted here (this wouldn't work with the GitHub edit)...
class MyCaptureMedia (CaptureMedia): def did_load(self): self.name = 'My Capture Media' self.background_color = 'Lime' self.left_button_items = [ui.ButtonItem(image = ui.Image.named('ionicons-close-24'), action = lambda sender: self.close())] self.lHelp = ui.Label() self.lHelp.text = 'Please choose media...' self.add_subview(self.lHelp) super(MyCaptureMedia, self).did_load() def layout(self): self.width = 320 self.height = 200 self.lHelp.x = 30 self.lHelp.y = 10 self.lHelp.width = 180 self.lHelp.height = 30
@Tony, Thanks for the explanations on the desire for extension points and
log_message(). Makes sense to me. I posted a pull request to re-add
log_message()and will try to put the extension points back into the GitHub source in the next 24 hours (if someone does not do so before I can).
Can we come up with a different name for
did_load()? Ole had reserved the
did_load()name for views that load ui resources from a .pyui file. A
did_load()in a script that does not use .pyui might confuse the casual reader. Given that all ui elements are created at runtime without .pyui, we should use a similar yet different name.
@ccc Good. Maybe... consider though... should the consumer of a class need to know or bother whether behind the scenes it's ui was implemented with the ui editor or with handwritten code?? The use of
did_loadhere was deliberate to create consistency and transparency.
I submitted a pull request which I hope solves the issues that you mentioned above.
I also opened a new issue on cancel and close.
In the base class... after cancel, tap outside the popover to close it and then the server closes because of the will close.
The sub class close button is the same scenario as the close from the POST I think... it seems to be a quirk of a programmatic close of a view presented in a popover that
will_closedoesn't automatically get called on the view in that case. Hence the second line at the end of POST to fix that. (present in a panel doesn't have that quirk I think, nor probably the other presents though I haven't tested.)
The sub class was a quick knock up to show the idea, but more properly I think the button item action would need to invoke both will close and close because of the quirk.
@ccc It's a bit of a fudge, but this addition to the base class seems to fix the quirk of present in a popover programmatic close for both the POST and the sub class button item action (and the fix line from POST can be removed)...
def close(self): self.will_close() super(CaptureMedia, self).close()
Updated source to version 2.0
p.s. I'm working on adding in a settings button and my SettingsSheet class for a switch to turn warnings on/off.
@techteej Thanks :) Likewise when iOS 8 is out I'll have a way to try to get it working on that.
capture_media generates an error on line 115 on my ipad air ios7.... any fix?
Looks like you should replace self._f with
You might also want to try one of the older versions (github history) since it seems like people checked in work without testing.
i've replaced the self._f at 2 locations, but there are still errors.
Which version in the history would your recommend?
Where is a working link?
