There are no real changes in this commit but it removes all trailing white space from our source files. This avoids problems when applying patches and making diffs and it would be nice to prevent it from reappearing. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@65680 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775

/*
|
|
* Experimental code to use operators for constraint specification.
|
|
* In the end, the syntax didn't look much clearer than
|
|
* the original, so abandoned.
|
|
|
|
Example:
|
|
|
|
wxConstrain(frame->panel,
|
|
|
|
( leftOf (frame->panel) = leftOf (frame),
|
|
topOf (frame->panel) = topOf (frame),
|
|
rightOf (frame->panel) = rightOf (frame),
|
|
heightOf (frame->panel) = 50 % heightOf (frame)
|
|
)
|
|
);
