Previously every widget border was drawn by two overlapping rectangles
to limit the number of primitives required to be supported by any
potential backend. The biggest problem from using this approach
is drawing overhead and no real way to get widget transparency. So
I changed border drawing to use stroked rectangles instead of a
second filled rectangle drawing call.
If you had any kind of popups like for example comboboxes inside a
deeper panel structure using nk_group, then `nk_xxx_close` would only
unblock input for the first level and not the whole panel stack. This is
now fixed and works correctly.
This is a breaking change which fixes bad closing behavior in
non-blocking popups. If the maximum size of a non-blocking popup was
not reached and you clicked to close the popup under it could happen
that it wouldn't be closed. This is now fixed in combination with
more popup control by allowing to set both the maximum height as
well as popup width.
Functions `nk_combo`, `nk_combo_seperator`, `nk_combo_string`,
`nk_combo_callback`, `nk_combobox`, `nk_combobox_seperator`, `nk_combobox_string`,
`nk_combobox_callback` all calculated the the height of the combo box
panel wrong and forces a scrollbar even if it was not required. The
calculation is now fixed and should produce the right result.
I removed the default vertex type and instead create an API to allow the
user to specify the vertex struct layout. Of course you are still
bound on what the library actual has on vertex data but the type and
sequence of the data is now configurable. This commit is quite
experiental and could introduce some bugs, but so far it look fine.
This commit fixed some bugs from the last commit as well as some general
changes and fixes of some old bugs. For overview of all changes please
look inside `CHANGELOG.md`.
This is a rather experiemental commit to remove some internal complexity
that build up over time handling panel padding and border. There still
could be some bugs but I tried my best to keep everything working.
Previously it was only possible to scroll windows and groups by mouse.
No it is possible to scroll popups, as well as nonblocking popups like
menus, contextuals and comboboxes. In addition I fixed a drawing bug
in dynamically growing panels.
To account for hash collisions which can be quite nasty I added
the string representation of the window name for additional
assurance. I also added an assert to check and alert if two windows
have the same name.
It is now possible to temporarily push some style values like color,
style items, font, ... into a stack modify the value and as soon as
you are done just pop the changes. Main benefit is less boilerplate
code to manually save and restore configuration properties.
SDL iOs implementation provides key press and release in
one frame and while nuklear previously was keeping track
of transistions it did not check it. It hopefully should now be
possible to correctly interpret up and down key in the same frame.
