I am just getting started and I am an experienced wxWidgets user.
First I noticed your provided sln on windows builds builds /MT and /MTd which as i understand it has noting to do with building a static lib. It is not the default and everyone's first project will fail to link. Changing it is fine but the lib name is not modified and that could cause issues. The CMAKE does not seem to address this. Just a suggestion.
I am trying to find better doc on the syntax used to set width etc.
Are size of buttons and labels either settable in ctor or sized with sizer? are they mutually exclusive?
Also Where is the STR() function or macro shown in the samples?
(need case sensitive search in forum, LOL )
