Under certain circumstances it is possible that because of floating
point error `nk_widget` will mark a widget as read only if used in
combination with `nk_layout_row`. The fix is rather simple in this
case since the additional floating point precision is not really needed
it is possible to just cast to int and remove the problem all togther.
There is now a difference between hiding a window with
`nk_window_show` and closing a window by clicking the close button in
the window header or calling `nk_window_close`. Only in the case of
activly closing a window will be removed at the end of the frame
besides getting removed if not updated inside the frame.
To support both string formats with string combined with length as
well as zero terminated strings I added a zero terminated string
version to `nk_edit_xxxx` with `nk_edit_string_zero_terminated`.
Fixed scrollbar auto hiding behavior to also work correctly if
the window is not hovered or manipulated in any way.
In addition I fixed a small panel padding bug in `nk_layout_widget`
for all panels outside windows which require a test on
`layout->flags` instead of `window->flags`.
The dynamic immediate mode layout API with `nk_layout_row_begin`,
`nk_layout_row_push` and `nk_layout_row_end` caused an infinite
scrollbar bug by wrongfully calculating the required widget sizes.
This bug is now fixed and everything is correctly calculated.
Previously I packed standard library variable arguments as well as
file operation into one define `NK_INCLUDE_STANDARD_IO`. This caused
some problems and I split the define into two. So if you want the old
behavior you need to define `NK_INCLUDE_STANDARD_IO` as well as
`NK_INCLUDE_STANDARD_VARARGS`. If you only want file operations but
not variable arguments only define `NK_INCLUDE_STANDARD_IO` and
if you only want varargs but not file operations please only define
`NK_INCLUDE_STANDARD_VARARGS`.
If you move the cursor to fast while scaling a window there is a
chance the mouse will miss the scaler and the scaling operation will
halt. Dragging in itself is quite hard but I implemented the hack I
use for property, window moving and slider for the window scaler and
scaling hopefully now works correctly.
This is quite an old bug and a result of being nearly stateless.
If you move/scale a window and another window is behind it the other
window will be acitvated and the move/scale operation will be stopped.
To fix this I now require no mouse down for activating by hovering.
I hope this does not cause any problems and fixes the problem for good.
I had a long standing bug inside nuklear which prevents you from
swapping out a font while the code is being build. This bug is now
fixed but the fix requires _ALL_ `nk_user_font` data structures
provided by `nk_style_set_font` to be persistent.
A previous push request added some macros into the header file and
I missed that it was outside the header include guard. This should
now be fixed and not cause problem if included multiple times in
different location.
Demos for x11 and sdl have been update so that `nk_xxx_handle_event'
return true (1) if the given event was usefull and processed by
nuklear and false (1) if not.
Since it was requested I added a small snippet showing how to create
notebook tabs (header with buttons, selecting content). The added
demo is basically just a combination of already existing widgets +
some small styling changes and can be extended to easily support
case with more tabs then space in the header part. I will have
to think about if it is possible to create an API for this without
taking away the simplicity of it.
Window scrollbar will if enabled by window flag hide if no user
interaction happens for a set time duration.
In addition the internal window/table data structs are now located
inside the header part of nuklear to remove the need to allocate a
pool and therefore simplify memory management.
Hopefully I finally fixed the hole inside combobox popup which only
occur if you set the window border size greater one. In addition
I fixed some subpixel drawing artifacts that come up if you use
antialising in combination with vertex buffer output.
I completely forgot to add the edit scrollbar style and
had a incorrect scrollbar bounds calculation. Both bugs
should now be fixed. Furthermore the edit ROM flag know
prevents any manipulating input instead of all input.
So it should be possible to move or copy inside the edit
field but not to modify the content.
For gui elements like tree tabs, tree nodes and windows themselves,
you can repeatedly click the same "minimize" region and it keeps
toggling that element. This was not the case with "popup" type of
elements. This commit slightly changes how the popups close once
they are already open.
Like before, the user can close the popup by just clicking outside
the popups region. Now the user can also close the popup by clicking
the "header" region of the popup.
