Changelog since 4.47.0 release to PyPI on 30 Aug 2021
4,47.0.2
4.47.0.2
New set_option parm: keep_on_top - all windows will default to this value. If all your main_window has keep_on_top set
then you likely want all of your popups to also have it set. Now set it one time using this option. You can override by manually
setting on a popup or window
Added user_settings_object to return the UserSettings object that the function level interfaces use (prints nicely for example)
4,47.0.3
4.47.0.3
Changed docstring for set_clipboard to take str or bytes
4,47.0.4
4.47.0.4
Changed ProgressMeter docstring to more accurately describe the weird size parm (it DOES make sense... just weird sense is all)
4,47.0.5
4.47.0.5
New parameter alias for elements.... p == pad. It is like the other 2 parameter aliases s == size and k == key
4,47.0.6
4.47.0.6
New parameter size_px for ProgressBar - yes, finally a sensible measurement for this element using pixels rather than chars and pixels
4,47.0.7
4.47.0.7
New alias for Stretch - Push - P. Stretch is a Widget name from Qt. I gave it some thought and realized what it DOES is Pushes elements
around. So, Push seemed like a good name, and it's shorter. I then also make the 1-letter version P.
4.47.0.8
New Table parameter / event. Setting the parm enable_click_events=True will cause events to be generated that are tuples when a user clicks on the table.
The event tuple format is: ('-TABLE KEY-', '+CICKED+', (3, 3)) 3 items in the tuple:
1. The Table's key
2. "An additional event name" in this case I've called it "+CLICKED+"
3. The (row, col) format that Jason designed where the header is row 0. I've thought about making the header row -1 so that the table clicks remain 0 based.
