after the last 6 or seven bugs I sorted out, another one. the redo button reacted not proper, but after enabling to connect a button to several events (one line of code), thats also no problem. Now i'm hitting toward the little problem in contextmenu on TabBar.
First i wanted to connect this contextmenu also into the main menu. but Wx seems to not support that. So I think a make 2 different menus, since i want to select on the tabbar just the files, and in the main menu the 3 commands (next, previeous, last used) also. since my idea was that the main menu is a bit of documentation, what the editor provides.
After that Problem also adressed, PCE really get's a stage of sanity that's nearly good for a major release.
