v3.1.0 Release.

This version fixes issue #11...

Thanks to @arminposchmann for reporting: in previous versions, using the line-divider in menus would break Reskinner. No longer a problem.

...and brings easing functions! (CSS lovers rejoice.)

Animated reskins can now utilize one of twenty-five built in easing functions of many types, including SINE, CUBIC, QUART, CIRC, BOUNCE and more to make transitions really pop, courtesy of @ai's gifted work with easings.net. If the 25 aren't enough, you can provide your own; the new easing_function parameter on the animated_reskin function takes any callable that takes the current animation timing as a float between 1 and 0, and returns the desired animation progress, also as a float between 1 and 0.

Once again, please give this project a star if you find it useful. Enjoy.

v3.0.0 Release.

This release brings major improvements and minor breaking changes to Reskinner, mainly:

• The exempt_element_keys, target_element_keys and honor_previous parameters have been removed from the reskin and animated_reskin functions. An element_filter parameter has been added instead, which takes any callable that takes individual PySimpleGUI elements and is expected to return either True or False, and if given, only elements that cause it to return True will be reskinned. This enables more complex element selection, like filtering or selecting even elements with no key.
• COLOR_SYSTEM_DEFAULT shouldn't be a problem anymore; Reskinner now makes use of actual default elements behind the scenes to obtain the right colors.
• The interpolation logic has been reworked; it no longer does any weird colordict manipulation.
• The color selection logic has been reworked as well, with caching as an added feature.

Future releases will focus more on performance and optimization, and possibly the return of the honor_previous parameter.

In the meantime, enjoy.

v2.3.13 Release.

Version 2.3.13

This version mainly addresses the issue with Default PySimpleGUI themes, specifically the issue with COLOR_SYSTEM_DEFAULT (or 1234567890), among other fixes and improvements.

Enjoy.

v2.3.8 Release

Version 2.3.8

This version fixes the instability observed after 1000 reskins, or 100 animated reskins, as first noted in issue #1 . It also removes the dependency on TITLEBAR_TEXT_KEY and other similar PySimpleGUI constants, instead finding the titlebar elements by introspection (fixing the side effect that caused issue #6 ).

Several other fixes have been made, all in all making performance more stable. Enjoy.
