RP #71

[Dirkster99]

Hi @LyonJack can you please use TAB character based indentations? It is otherwise very hard to see the changes because the whole document is marked as changed in GitHub's Web-Interface. Thank you Drk

[LyonJack]

Where is the setting of tab character indentations?I use the default setting of vs,when I try to 'Ctrl + K +D' to format the codes，all of the codes‘ indentations will be changed

[LyonJack]

It’s the chang of all my commit:
1、change override void OnPreviewGotKeyboardFocus to OnPreviewMouseLeftButtonUp
2、change the debug info
3、fix #71 ,look the picture of the chang

OK, I understand the change now but the indentation in the file in your branch is not based on the TAB character as you can see in this image where I compare the file in:

• your branch (on the left) with the file in
• dirkster99/AvalonDock/master branch

I have used Edi to visualize SPACE versus TAB character but you can use any editor (VS, Notepad++) to make Spaces and TABS visible

The VS Community Setting I am using is this (but there might be a way to make this project specific):

I normally don't care that much about it and change it later to TABS but it makes the [merge view]
(master...LyonJack:master) increasingly hard to interprete because it simple shows the whole file as being changed :-(

[LyonJack]

next time I'll use tab

OK no big deal - I just thought I mention it because its a bit of a hutzle - I used to use spaces as well but somehow everyone else seems to prefer TABS so I switched to TABS some time ago ...
