'''Screen
|
|
======
|
|
|
|
This module changes some environment and configuration variables
|
|
to match the density / dpi / screensize of a specific device.
|
|
|
|
To see a list of the available screenid's, just run::
|
|
|
|
python main.py -m screen
|
|
|
|
To simulate a medium-density screen such as the Motorola Droid 2::
|
|
|
|
python main.py -m screen:droid2
|
|
|
|
To simulate a high-density screen such as HTC One X, in portrait::
|
|
|
|
python main.py -m screen:onex,portrait
|
|
|
|
To simulate the iPad 2 screen::
|
|
|
|
python main.py -m screen:ipad
|
|
|
|
If the generated window is too large, you can specify a scale::
|
|
|
|
python main.py -m screen:note2,portrait,scale=.75
|
|
|
|
Note that to display your contents correctly on a scaled window you
|
|
must consistently use units 'dp' and 'sp' throughout your app. See
|
|
:mod:`~kiv.metrics` for more details.
