question on nc-input demo

[kascote]

Hi, I'm toying doing a binding for dart and was trying to replicate the nc-input demo to test some implementation details.
Following the nc-input code I saw something that is not clear to me (I do not understand some things of c,c++ and I'm new to notcurses too).

this line is printing some text usingNCAlign::Center
https://github.com/dankamongmen/notcurses/blob/master/src/input/input.cpp#L292

but the n plane was not created with HORALIGNED flag
https://github.com/dankamongmen/notcurses/blob/master/src/input/input.cpp#L258

HORALIGNED is only setup for the "plot" plane
https://github.com/dankamongmen/notcurses/blob/master/src/input/input.cpp#L274

The question is: why the text is displayed centered when run the demo if the plane do not has that flag setup?

[dankamongmen]

NCPLANE_HORALIGNED isn't about the text within the plane, but rather about the plane's placement relative to its parent plane.

when i create a plane with NCPLANE_HORALIGNED using NCALIGN_CENTER, i'm saying "stick this plane horizontally in the middle of its parent plane." so if say the standard plane is 80 columns wide, and i make a new child plane using NCALIGN_CENTER and the new plane is 40 columns wide, it'll be placed at the 20th column.

within a plane, using NCALIGN_CENTER together with e.g. ncplane_printf_aligned() aligns within the plane.

does that answer your question?

yes perfect.. putstr is overloaded a couple times, I was looking at the wrong one.
thanks an have Happy New Year!
