BeginChild() make its area loose the ability to move a window

[djdeath]

Hi,

I'm trying to layout a window so that there is a top part that doesn't scroll, and the bottom part is a list that can be scrolled :

This can be implemented by using BeginChild()/BeginChildFrame() for the scrolling part.
The slightly annoying problem with this is that previously the entire window would be reactive to click-and-drag (so you can move it by clicking anywhere), but now only the part outside of BeginChild/EndChild has that ability.

Is there a way around this?

Thanks!

Looks like this commit broke it:
313d388
It needs to be looked at.

(Btw I'm not sure why you are using BeginChildFrame and not BeginChild here, and your UI looks really hard to read).

Thanks, indeed, BeginChild() looks much better.
I was just trying out all possibilities.

Should be fixed now!
Note that you can use the ImGuiWindowFlags_NoMove flag on a child window to explicitly disable this if needed.

Wow thanks you so much! All good now 👍

Please note that BeginChildFrame() now has been obsoleted in favor of using BeginChild() with the ImGuiChildFlags_FrameStyle flag. See commit cdbc21a.

I have currently made ImGuiChildFlags_FrameStyle automatically set the ImGuiWindowFlags_NoMove flag but since the API changed I may backtrack on this. However it seems more consistent for user experience to do it.

Those functions were merely PushStyle/PopStyle helpers and custom versions are easy to create.

(The removal isn't so much motivated by needing to add the feature in BeginChild(), but by the necessity to avoid BeginChildFrame() signature mismatching BeginChild() newer signature and features.)
